    Notes: An analysis was made on 140 adult chickens of the relationship between visual estimation of the degree of encroachment of the lumen of the vessel by plaques and such morphometric variables as weight, length, circumference, thickness, density, and combinations thereof of the thoracic and abdominal segments of the aorta. Aortic weight and thickness functions were found to be significantly correlated to scores, accounting in the two highest cases (thickness and weight/area of the abdominal segment, body weight held constant) for 46% (r = 0.68) and 42% (r = 0.65) respectively, of the variability in score. Correlations were considerably lower in the thoracic segment, the highest being r = 0.36 for weight/circumference. The scoring thoracic segment, the highest being r = 0.36 for weight/circumference. The scoring system thus has a basis in measurable physical changes in the wall of the blood vessel, but scoring apparently evaluates considerably more than was measured by the morphometric variables. The morphometric variables would probably serve best as means of comparing different scoring systems and as objective supplements to scoring. The procedure of choice would appear to be weight/area with body weight held constant (i.e.  -  partial correlation and/or covariance analysis).

    Notes: Wistar strain albino rats were injected with 1 cm3 of a 1% solution of trypan blue. Three types of dye were used: Matheson, Coleman and Bell, Chroma-Gesellschaft and a highly purified sample. The dyes were injected on days 6, 7, and 8 of gestation. Fetuses were excised from days 16 through 20, fixed, decalcified where necessary, embedded in paraffin, serially sectioned and stained. Newborn young were treated similarly. Chroma-Gesellaschaft trypan blue was without reproductive or teratogenic effect at the above doses. Increasing the dose did not increase the teratogenicity but did yield a decrease in litter size. Both Matheson, Coleman and Bell trypan blue and the purified sample were teratogenic. The most frequent neural defect observed was hydrocephalus. Serial sections of the newborn hydrocephalics showed an occluded or extremely tenotic aqueduct of Sylvius in 31 of 33 sectioned animals. The fetuses collected from days 18 through 20 also had occluded or stenotic aqueducts if hydrocephalic. Aqueductal stenosis or occlusion was present in 17-day-old fetuses, but hydrocephalic was not conclusively demonstrated at this age. Sixteen-day-old fetuses did not have aqueductal occlusion in any of those examined, but stenosis was evident. It is concluded that the defect predisposing to hydrocephalus in the young of trypan blue treated rats of this strain is aqueductal stenosis or occlusion.

    Notes: Follicular activity in the ovary of the pregnant hamster is divided into two periods. During the first eight days (corresponding to the duration of pseudopregnancy) an average of 11 follicles per ovary from 277 to 553 μ are present. From day 10 to 16 of pregnancy, the ovary contains 22 follicles ranging from 277 to 600 μ and larger. The day after parturition, atresia destroys all large multilayered and vesicular follicles.Hamsters injected with human chorionic gonadotropin on day 4 of pregnancy ovulated ten ova, whereas similary treated day 12 animals ovulated 35 eggs. No cyclic follicular activity corresponding to the length of the estrous cycle occurred during gestation. On the contrary, a constant increment of small follicles took place throughout pregnancy.

    Notes: A plastic sealing compound for museum jars is described. It has the consistancy of toothpaste and is applied in a similar manner directly to the museum jar from a tube. No catalyst or mixing is required. Moisture in the air cures the plastic in 12-24 hours. After the extruded “rope” is applied, the lid is placed on the jar and the jar set aside for the cure. After cure any excess can be trimmed with a scalpel.

    Notes: A method is described for making simple balloon cannulas. These may be inserted into the depths of the brain of the experimental animal and inflated, resulting in the production of a permanent destructive lesion characterized by hemorrhagic necrosis of the parenchyma, elements of the stroma being preserved peripherally. In time, a smooth, well-defined membrane delineates the oval shaped cavity resulting in a sharply punched-out lesion. A reversible lesion cannot be produced by this technique. Such lesions may have further clinical or experimental value. The local application of radioactive isotopes to specific areas of the brain under controlled situations permitting withdrawal of solutions may be possible by this method.

    Notes: The excessive growth of fatty tissue around atrophic organs has been described in humans as “hypertrophy ex vacuo”. Since adipose tissue receives its blood supply from smaller branches of arteries which also supply organs or muscles, it has been suggested that increased amounts of blood could be diverted from the inactive organs to the surrounding fatty tissue and promote its growth. This theory was investigated, using rats and mice of different strains. One testis, the artery of which also supplies the epididymal fat pad, was removed, and the animals sacrificed 3-4 weeks later. Growth of the affected fat pad in both rats and mice of normal body composition was significantly reduced. Removal of the testis in adult yellow-obese mice during periods of weight gain produced a moderate but significant weight increase of the affected fat body.

    Notes: The right knees of rabbits were rigidly fixed with metal clamps midway between full flexion and full extension. After six dayas the knees of six were preserved while clamped. Twenty other rabbits were sacrificed after 16 days. Ten received colchicine on the eighth, eleventh and fifteenth day following clamp application. Their knees were preserved after clamp removal. The femoral and tibial articular cartilages subjected to pressure for six days were extremely compressed but viable. In knees clamped for 16 days the changes found were related to the amount of knee movement present at autopsy. Where it was small but easily detectable the cartilages were normal. Where there was no movement the cartilage was dead. Where it was only slight variable cartilage changes were found ranging from surface abradement, Matrix swelling, enlargement of lacunae and chondrocytes, increased number of cells per lacuna, and an occasional chondrocyte in mitosis, to an extensive matrix alteration resulting in the disappearance of lacunae, chondrocytes released from the confines of lacunae and interspersed among a meshwork of fine collagen fibers, and a few released chondrocytes in mitosis. The most extensive change was where the cartilage defect area was occupied by a mass of proliferating richly-cellular tissue. The knee articular cartilage changes of this experiment are compared with those occurring during pregnancy in the pubic symphyseal cartilage of mice.

    Notes: A study of nerve-muscle relations and fine innervation patterns is reported for the stapedius muscle of the cat. Gross relations of the muscle to its associated nerves and other middle ear structures are shown by illustrations. Histologic features of innervation are studied with the Bodian silver method. the thiocholine technique, and iron hematoxylin and osmic acid stains.The muscle is richly supplied by 3 to 4 facial nerve branches in which no axons are found above 8 μ and the majority are unimodally grouped at 2-4 μ. The auricular nerve of the vagus does not penetrate the muscle. Three to four distinct zone is of fasciculi are found whose muscle fibers are 14-20 μ in diameter. Each zone is supplied by primary nerves whose branches do not exhibit terminal overlap or multiple innervation of muscle fibers. Short terminal axons lead to motor and plates from all intramuscular nerve branches. Nerve branches and motor end plates are confined to the basal third of the muscle. Sensory endings are not detected within the muscle or its tendon. It is estimated that each motor neuron supplies no more than five muscle fibers but more probably three or less.

    Notes: While studying the electrocardiograms of developing hearts it was noted that an adult type ECG could not be obtained in an embryonic heart which could not be blocked with digitalis. The need to know more about heart-block was obvious. Intact embryos of 36 to 120 hours were floated on to glass plates and treated with digoxin-Tyrode solution. Before 36 ± hours no dissociation of beat could be produced. The heart just stopped. At 40 ± hours a conal block followed by a midventricular block appeared. At 42 ± hours conal and midventricular blocks were followed by the first appearance of AV block. It was intermittent. At 47 ± hours conal block jumped to an incisive AV block. Midventricular block was rare. At 72 hours conal and then AV block occurred. Combinations such as four atrial to two ventricular to one conal beat could be readily produced while blood circulated.Electrocardiograms and cinephotomicrographs were taken of 72 and 96 hour hearts. Most striking was the fact that the typical Wenckebach phenomenon of adult heart-block could be duplicated, i.e., an increase of PR interval preceding AV block followed by a shorter PR interval which again gradually increased preceding AV block. This sequence was repeated over and over. An explanation of these events is offered.

    Notes: This study was undertaken to determine the relationship between Marshall's metalophilic reticular cells and the cells exhibiting non-specific esterase and acid phosphatase activity in the rat spleen. Untreated and stimulated animals were used. Observations were made chiefly on the marginal metalophils of Snook. These cells showed strong acid phosphatase activity but only slight non-specific esterase activity in untreated animals. Following stimulation non-specific esterase activity increased in these cells. Within the nodules metalophilic reticular cells were always more numerous than cells with enzyme activity. Many of these metalophilic cells developed enzyme activity following stimulation. By the use of a restaining technique it was shown that all reticular cells possessing enzyme activity were also metalophilic but that the converse was not true. No mitotic activity was present in these cells.The results suggest that Marshall's metalophils are cells of the reticuloendothelial system in various stages of maturation and that, following stimulation, they may differentiate into mature phagocytic cells.

    Notes: In the normal parathyroid gland of the mouse there is only one type of cell which is small with a large nucleus and small amount of cytoplasm. In order to investigate the effect of relaxin on parathyroid histology, mice were injected with relaxin, the degree of pubic separation was measured by the x-ray technique, and the parathyroid glands were studied histologically. After one day of relaxin injection, the pubic symphysis showed a distinct separation and in part of the parathyroid gland the cells were larger and stained lighter and pinker than the normal cells with hematoxylin, eosin, and azur II. After four days of relaxin treatment, the whole gland had changed so that all the cells were of the second type. Glands of pregnant mice near term also were composed of cells of this type. These results indicate a relationship between relaxin and the parathyroid gland.

    Notes: Comparison of results obtained by S35O4= autoradiography with those from histochemical staining methods and evaluation of the effect on the staining resulting from prior sialidase digestion, methylation, methylation and saponification, or sulfation, substantiates the selectivity of some procedures for sialomucin and others for sulfomucin. These two types of mucopolysaccharide may be differentiated by the high iron diamine-alcian blue or aldehyde fuchsin-alcian blue sequences or comparison between staining with the alcian blue pH 2.5-PAS sequence and staining with the alcian blue pH 1.0-PAS method. These techniques reveal that some rodent or lagomorph salivary glands form sialomucin alone, others apparently only sulfomucin, whereas a number produce both types of acid mucopolysaccharide either in different mucous cells throughout the gland or in the same cell.Differences in affinity for basic dyes, periodate reactivity, and susceptibility to elimination of basophilia by methylation or enzymatic digestion are evident among both the sulfo- and the sialomucins in different glands. After brief saponification the sialomucin in rat sublingual glands becomes sialidase digestible and gains alcohol resistant metachromasia.Several serous or seromucous glands secrete neutral mucopolysaccharides; others secrete polysaccharides containing sulfate or sialic acid groups whose affinity is masked for some but not for other basic dyes.

    Notes: Neuroanatomical nuclear configuration corresponding to the projection regions for the chorda tympani, the IXth, and the lingual nerves was studied in the cat thalamus by a combination of electrophysiological, stereotaxic, and histological techniques. Each of the three nerves innervating the tongue was dissected for stimulation in cats deeply anesthetized with Nembutal. Maps of the extent of the thalamic projection for a particular nerve were obtained by recording evoked potentials in the thalamus during the stimulation of one of these nerves. Such maps were correlated with the anatomical structures of the cat thalamus by reconstructing the recording sites from histological sections of the cat brain. It was found that the chorda tympani and the IXth nerve projection regions correspond closely to the ventromedial nuclear complex with slight encorachment on the lingual nerve projection region in the ventrobasal complex. The most medial portions of the taste nerve projection regions do not relay any tactile afferent impulses and the most lateral portion of the lingual nerve projection is not activated by impulses in the taste nerves. Therefore, it is suggested that the thalamic relay of taste is not coextensive with other lingual modalities in the cat thalamus but it has an independent representation in the ventromedial nuclear complex.

    Notes: Analysis of age changes in physical characteristics of mouse limb bones requires a sensitive, consistent and relatively simple apparatus for determination of transverse breaking strength. The developed instrument is essentially a one meter counter-balanced 4-to-1 lever with a tracked, motor-driven weight on its upper surface. At the beam's short end a loading tool impinges upward on a bone mounted in an adjacent holder; at the opposite end is a mercury switch connected to a relay halting the weight motor when fracture occurs. Bones, with proximal ends embedded in convex securing blocks of impression medium, may be positioned in a standard relationship to the holder, loading tool edge, and the balanced beam.Repetitive loading of a steel spring indicates instrument error of 1.8%. Preliminary tests with a random series of paired mouse femora show no significant difference between left and right bones. In the long-term study it will be possible to correlate physical strength with other characteristics of opposite bones.An air-gap capacitor across loading tool and bone holder and coupled to a variable frequency oscillator permits monitoring of specimen elasticity on a strip-chart recorder.

    Notes: The area of new cell formation, the rate of proliferation, and the manner in which cells are lost from the intestinal epithelium in the turtle, Chrysemys picta, were studied using a cell labeling technique with tritiated thymidine and mitotic inhibiting technique with colchicine.In the intestinal epithelium of Chrysemys picta, cellular proliferation was observed to occur in the layer of cells adjacent to the basement membrane. Mitosis occurred throughout the epithelium at a fairly low rate (mitotic index 0.0016). In the upper intestine fewer labeled cells were found in the apical one-third of a villusfold than in either the mid or basal one-third. The time required to renew the intestinal epithelium, was estimated to be about eight weeks in winter turtles maintained at 20° to 24°C.Cell loss from the system appeared to be due to a randomly located movement of cells lumenward from the basement membrane.Mitotic activity in cold torpid turtles (11°C ambient temperature) appeared to be completely suppressed as shown by a lack of incorporation of tritiated thymidine and an absence of mitotic figures in the intestinal epithelium.The term villi-folds was proposed to provide a category for those animals possessing structures having characteristics both of villi and of folds as found in C. picta.

    Notes: The volumes of parenchymal cells and their nuclei in liver were calculated in white rats, Columba livia (rock pigeon), Calotes versicolor (garden lizard) and Bufo melanostictus (toad); from their optical area and cell thickness. The area was measured from camera lucida drawings. The largest cellular and nuclear volume was observed in rats and smallest in pigeons. The cell volume in toads was similar to that found in rats but they had smaller nuclei. The cellular and nuclear volumes in lizards were smaller than in toads; and in pigeons smaller than lizards. The significant difference, in both cellular and nuclear volumes that has been observed in different classes of vertebrate, cannot be correlated with the evolutionary changes.

    Notes: In the literature the nutrient artery to the diaphysis of the canine femur has been described as arising from the medial circumflex femoral artery which is a branch of the deep femoral artery. However in 19% to 100 canine hind extremities dissected after injection with colored media, the femoral nutrient artery arose from a large muscular branch (the proximal posterior femoral) of the superficial femoral artery. In 17% of 42 dogs one femur only was supplied by this variant. In three additional femurs other variations occurred.

    Notes: Ectopic glomeruli and proximal convoluted tubules were found in the kidneys of the rat, cat, dog, rabbit and ferret and in the human full-term fetus. They lay in the connective tissue around the main intrarenal vessels and deep to the pelvic mucosa. Their afferent arterioles were long and gave branches to the pelvic mucosal plexus, while their efferents supplied the pelvic mucosa and the medulla, or one or the other of these tissues. In the rabbit the ectopic glomeruli often produced small cysts in the pelvic septum. Degenerating ectopic glomeruli were occasionally found and in the dog the majority of them showed this change. In the adult human kidney, aglomerular arteries supplied both the pelvic mucosa and the medulla and it is suggested that such arteries are the result of degeneration of ectopic glomeruli.

    Notes: A purified diet lacking folic acid and containing 20 mg% of the antimetabolite, 9-methyl pteroylglutamic (folic) acid was fed to female Long-Evans rats during days eight and nine of pregnancy. Embryos were removed at autopsy on the tenth day of gestation for study and comparison with embryos from normal control pregnancies.Analysis of mitotic counts revealed that 18.6% of the cells in control embryos were in mitosis in contrast to only 5.7% in PGA-deficient embryos. A disproportionate reduction in anaphase and telophase stages was observed in conjunction with an increased percentage of cell at metaphase. Concomitantly with these mitotic changes a marked reduction in histochemically demonstrable RNA and in numbers of ribosomes as revealed by electron microscopy was observed.

    Notes: The perineal pigment spot of the C57 Black mouse was examined macro- and microscopically in animals ranging in age from 14 days post-fertilization to 28 days post-parturition. Dendritic pigment-containing cells first become evident in the dermis of the area on the sixteenth day post-fertilization. Throughout later stages of development, these pigmented cells continue to be restricted to the dermis of this area. Since the dopa treatment reveals the presence of a melanin synthesizing system within these cells, they are true melanocytes which have become restricted to this layer of the integument.Histological examination reveals a population of melanocytes in the epidermis and/or hair follicles also. These are rarely found over the center of the area but are seen in increasing numbers laterally from the ventral midline. In contrast, dermal melanocytes are heavily concentrated near the ventral midline but decrease in numbers laterally. There are, therefore, two opposing but complementary gradients of melanocytes in the integument of the pigment spot. This suggests the possibility that a precocious differentiation of the basement membrane in this area during embryonic development inhibits the passage of melanoblasts into the epidermis thereby causing them to be restricted to the dermis.

    Notes: Electron microscopic studies reveal that the red pulp of the rabbit spleen is composed of reticular cells, reticulum and elements of the blood circulating through it. The three types of reticular cells described follow no definite pattern as to types of spaces they line and are not always adjacent to a basement membrane. Similar or dissimilar cells may line a basement membrane on the same or opposing sides. The entire red pulp area is intercommunicating through pores and junctions of the several spaces and in that area in which no basement membrane exists, the cytoplasmic projections of the reticular cells form a meshwork of spaces. Terminal arterioles are seen to end in collapsed type channels with a change from endothelium to Type I reticular cells. These rapidly join dilated areas. The reticular network of the spleen appears as four types: homogeneous, fibrillar, a combination of these, and reticular cells only. Isolated cilia are found in the reticular cell cytoplasm and are shown to be associated with a basal body and a centriole. The investigation supported the hypothesis that the red pulp of the spleen in the adult rabbit is a functionally dynamic area constantly changing its histological structure, both regarding cells and state of the vascular channels.

    Notes: The ultimobranchial body was investigated in 63 specimens of Rana pipiens. The morphology is described for “typical” (unifollicular) glands and those found in animals in poor physiological (“stressed”) condition. The typical follicular epithelium is of a mixed pseudostratified type and includes “elongate” cells which extend from the basement membrane to the free surface. These contain elongated nuclei, prominent terminal lipid droplets and “deltoid bodies” which are triangular, homogeneously staining structures apical or basal to the nucleus. “Isometric” cells do not extend to the basement membrane. They posses intensely staining nuclei, few lipid droplets and no deltoid bodies. The stressed gland is multifollicular and degenerate. Mitochondria, lipid droplets, deltoid bodies and glycogen have been identified and are located in specific areas of the follicular cells. The secretory products within the lumina of the glands have tentatively been shown to contain acid mucopolysaccharides, carbohydrate-protein complexes, mucoproteins, lipid droplets and lipid complexes. These secretions may either represent possible precursors to future secretions or a retention of secretions produced during metamorphosis. The ultimobranchial body has shown no indication of degeneration in the adult.The ultimobranchial body in typical Rana is an active secretory gland which shows no indication of degeneration in normal adult anurans. Furthermore, it responds to fluctuations in environmental conditions as illustrated by its altered structure and varied types of secretion when stressed.

    Notes: Conventional radiographs of lungs of calves which had been injected post mortem with barium sulphate could not be used to demonstrate vessels smaller than 50 μ in diameter. To overcome this difficulty, frozen sections 50-150 μ thick were floated on to high resolution photographic plates and contact microradiographs made using soft radiation. The resultant microradiogram was then viewed and photographed with the light microscope. It was possible to visualize the smaller arterioles and the capillary networks around the alveoli. The technique is simple and gives reproducible results.

    Notes: UDPG-glycogen synthetase was studied in the uterus of ovariectomized and ovariectomized-hormone treated rabbits and in the tongue. Following the biochemical technic of Leloir and Goldenberg it was not possible to demonstrate the enzyme in the uterus of the ovariectomized or ovariectomized treated animals. However, in the tongue the enzyme was present. The data from this study along with previous histochemical studies indicates that the glycogen in the uterine muscle is not synthesized through the UPDG pathway, but is synthesized from G-1-P by the action of phosphorylase. Since UDPG-glycogen synthetase can be demonstrated in the tongue a difference seems to exist in glycogen synthesis between the smooth muscle of the uterus and skeletal muscle of the tongue.

    Notes: The A-V node of the dog is composed of closely interwoven fibers which frequently connect with each other within a sparse collagen framework. Fibers from the interatrial septum enter the posterior half of the node along its superior and posterior margins, while the anterior half of the node is isolated from such connections. In addition there are fibers from the interatrial septum which bypass these marginal atrionodal junctions and instead enter the convex surface of the node, which lies beneath the right atrial endocardium. These bypassing fibers circumvent most of the interweaving fibers within the A-V node. At the posterior margin of the node, lying between it and the coronary sinus, there are ganglia and nerves, with the nerve fibers extending anteriorly through the A-V node into the A-V bundle. The only major anatomic difference between the human and canine A-V nodes is their arterial blood supply, that of man being derived from one source originating from the right coronary artery and that of the dog being from two sources, both of which originate from the left coronary artery.

    Notes: Experiments reveal that growth reactions may be evoked in amputated forelimbs of fully adult Rana pipiens and R. catesbiana by electrical stimulation of the normal limb nerve supply. The evoked growths were generally small cones, 5-10 mm in length; none developed into limbs of normal size and morphology, but some formed digits and cartilage and developed striated muscle. The combined influences of trauma, effected by salt treatment, and electrical stimulation of the nerve produced more growths than trauma or stimulation alone.

    Notes: Vital staining by trypan blue was used to demonstrate macrophages within involuting (post-secretory), lactating and resting mammae of mice. Involution was produced by removal of the nursing young on the eighth day post-partum when maximal lactation was present. The number of macrophages in involutin mammae was not significantly greater than that found in the rsting glands of mice receiving comparable injections of dye. Macrophages (coarse, granular accmulations of trypan blue in cytoplasm) in involutin mammae were congregated around and within atrophic alveoli and small ducts, while in lactating and resting mammae they were located primarily in the areolar stroma. Plasma cells, lymphocytes and neutrophils were increased during involution, but the limited leucocytic response did not indicate that a significant inflammatory reaction was active in the process of involution. Difuse parenchymal staining, indicating cellular injury or death, was limited to the epithelium of necroptic ducts and alveoli of involuting glands. Granular deposits of dye, as in macrophages or renal tubular epitelium, were not seen in the resting, lacating or involuting mammary parenchyma.

    Notes: Embryonic thymus provides a distinct advantage over the definitive thymus because the earliest formation of lymphocyte and lymphocytic precursors can be observed in a relatively simple and uncomplicated situation. Special cytological techniques combined with light, phase, and electron microscopy have been performed in this investigation involving over 150 chick embryos between 5 and 18 days of embryonic development.Sequential cytological changes in the development of the thymus into an active lymphocytopoietic organ indicate that lymphoblasts develop by the gradual proliferation and transformation of “undifferentiated” epithelial cells comprising the primordial thymus. Lymphoblastic transformation begins on the seventh day of embryonic development in the chick and is characterized by increased cytoplasmic and nucleolar basophilia and chromatin condensation. “Undifferentiated” epithelial cells undergo two distinct lines of differentiation between the seventh and tenth days: into lymphoblasts and into stellate reticular-epithelial cells which constitute the organ parenchyma. All stages of lymphocytic maturation may be observed by 10-11 days as the thymus assumes a predominately lymphocytic character. Absence of lymphocytes or lymphocytic precursors in the connective tissue surrounding the embryonic thymus before and during the period of initial lymphoblastic transformation; presence of a continuous basement membrane surrounding the developing thymus; and absence of cells passing through this membrane during this phase of development indicate that the lymphocytic elements appearing in the embryonic thymus parenchyma are of epithelial rather than mesenchymal derivation. Although a contribution of mesenchymal elements to the lymphocytic population via vascular invasion and lobular formation in later stages of thymic development is unlikely, this question cannot be answered at this time. In spite of functional immunological distinctions between the lymphocytes of the chick thymus and bursa of Fabricius, the similarity of origin of the lymphocytic elements of these lympho-epithelial organs is apparent.

    Notes: The cytoplasm of the megakaryocyte in the rat spleen possesses three zones, the perinuclear, intermediate and marginal. The perinuclear zone is characterized by the presence of Golgi apparatus, ribosomes, endoplasmic reticulum, and mitochondria. These organelles are found also in the more voluminous intermediate zone which in addition exhibits platelet granules and an extensive development of vesicles from smooth-surfaced endoplasmic reticulum to form demarcation membranes by coalescence. The marginal zone is almost devoid of the organelles and inclusions present elsewhere. Shedding of platelets appears to occur by extension of a paired demarcation membrane from the intermediate zone to the cell membrane and subsequent separation of its lamellae so that all of the essential organelles and inclusions of the intermediate zone may be included within the platelet. In addition, platelets contain vesicles which are probably pinocytotic in nature. Platelets are sometimes engulfed by the cytoplasm of phagocytic cells.

    Notes: A technique was devised for obtaining marrow-free trabecular bone so that the trabecular and cortical bone composition of dog, steer, monkey and man could be studied. Vertebral body was cut in the frontal plane into slices 2 mm thick with an electric band saw. The cortical bone encrircling each slice was trimmed off with a cleaver, leaving intact a lacy slice of trabecular bone. The marrow substance was washed away by fine and powerful jets of tap water obtained from an adjustable nozzle. Marrow washing was discontinued when no trace of red color was visible on holding the slice in front of a strong light source.The quantities of water, volatile inorganic, organic and ash fractions in cortical bone was alike for all species. Likewise, the trabecular bone fractions of each was quantitatively similar. In general, density and amount of ash in cortical bone was higher than that in trabecular bone. The water and ash:organic ratio were higher in trabecular than in cortical bones.Ratios of trabecular to cortical ash for the bones in an entire dog skeleton were also determined. Based on this, volume or mass of the various bone fraction may be estimated when the weight of the ash for any particular bone is known.

    An improved method for evaluating osteogenesis in vitroSupported in part by a grant from the Squibb Institute for Medical Research and by the United States Public Health Service grant no. GPD-16, 196. (1964)

    Notes: A simple, rapid method is presented which permits qualitative evaluation of osteogenesis in tissue culture. Eleven-day embryonic chick tibiae, with distal and proximal condyles removed, were grown in organ culture for two weeks. Explants demonstrated subperiosteal osteogenesis, bridging of fracture defects, and formation of bone, de novo, over the cut cartilaginous end surfaces of explants.The method presented herein has several advantages over those previously described and may be adopted for an in vitro assay of materials to determine direct effects on osteogenesis. Large quantities of explants can be prepared easily and cultured to yield consistantly abundant quantities of osteoid. Bone which is formed over ends of anlage is particularly significant by virtue of its position. New bone formed elsewhere in explants, with the possible exception of the fracture sites, however, is difficult to distinguish from bone present before onset of cultivation. Further more, osteogenesis which occurs over the cut cartilaginous ends after a week of culture, probably results from favorable environmental conditions in vitro and not from cellular activity “preprogrammed” in ovo.In addition to osteogenesis, alteration of cartilage cells and matrix were observed in this system. Chondrocytes in the cut ends of the anlagen became spheroidal and resembled osteoblasts. Bone formation, however, was not observed about these cells. In and about lacunae of degenerating chondrocytes at the ends of the anlagen, collagen fibers appeared.

    Effect of transplacental mitotic inhibitors on the fetal hamster eyeSupported by U. S. Public Health Research grant GM 10210-01. (1964)

    Notes: Congenital malformations of the hamster eye, consisting of microphthalmia and anophthalmia have been noted consistently in the offspring of pregnant hamsters treated with intravenous injections of colchicine, Vinacaleukoblastine (VLB) and Vincristine (VCR) on the eighth day of gestation. In an attempt to compare the mitotic-arresting activity of these three compounds on the lens and retina of the fetal hamster eye, various concentrations of the drugs were injected into pregnant hamsters on the fourteenth day of gestation and the fetuses recovered after three hours. Mitotic counts were done on comparable sections of lens and retinas of the fetuses. Colchicine has the most marked mitosis-inhibiting activity of these three drugs. The most effective mitosis-inhibiting dosage of colchicine also correlates with its most effective teratogenic dose. VLB and VCR do not inhibit mitosis in the fetal hamster eye as markedly as colchicine and their most effective mitosis-inhibiting dosages are equal to or above levels which cause a 95-100% embryonic mortality. It is possible that some common biological mechanism other than inhibition of mitosis may be responsible for the similar teratogenic activity of these compounds. The natural resistance of the golden hamster to colchicine does not appear to be manifest in the developing embryos in utero.

    Notes: Intimal proliferation in dog coronary arteries occurred in the vessel having the greatest range of motion. Within an involved segment of the artery, intimal proliferation could be related to the anatomy of the muscle bundles. Arterial muscle bundles originate from the adventitia, spiral around the artery and insert distally into the adventitia. The adventitia and the internal elastic lamina course along the long axis of the artery and are connected by elastin-collagen fibers. Intimal thickening developed under the muscle insertion sites in regions where the adventitia was apparently placed under tension. In these regions, the net force of a muscle bundle contraction increases and shearing would occur between a muscle bundle at its insertion site and the remaining bundles gliding past it. This local shear force would then be transmitted to the internal elastic lamina through the elastin-collagen fibers which connect it to the adventitia. Deformation and apparent injury of the internal elastica would follow and cause a fibrous tissue response. In the smaller arteries and arterioles, intimal proliferation occurred most prominently in the vessels supplying a mobile structure, i.e., anterior papillary muscle of the left ventricle.

    Notes: This report on the early human ilium is based on the Streeter collection, Carnegie Institution of Washington, Department of Embryology, Baltimore. The five phases in chondrogenesis, described by Streeter for the humerus ('49) and the horizons (Streeter, '42) are used in the description of the changes observed in the ilium. From horizon XV (7-8 mm, 30-32 days) to horizon XVIII (14-16 mm, 36-38 days) component cells of the ilium are mesoblasts. In horizon XIX (17-20 mm, 38-40 days) young cartilage cells have appeared. Both phase 1 and phase 2 cells appear in horizon XX (21-23 mm, 40-42 days), the former characterized mainly by the first appearance of intercellular material, the latter by their slender shape and arrangement in tiers. Phase 3 cartilage cells, cuboidal with many vacuoles, appear in horizon XXI (22-24 mm, 42-44 days). Increasing vacuolization of the cytoplasm of cells is noted throughout horizons XXII and XXIII until, in horizon XXIII (28-30 mm, 46-48 days) total disintegration of cells, a feature of phase 5, is evident. Thus the phases of cartilage differentiation described for the humerus are present also in the ilium.

    Notes: The luminal and glandular epithelia of the rat uterus during delayed implantation have been studied with the electron microscope. The tall columnar cells of the luminal epithelium are characterized by a distinct zonation of organelles. On the free surface there are short microvilli and occasional cytoplasmic extrusions, with terminal bars joining adjacent cells at their apical margins. Beneath the free surface are numerous pinocytotic vesicles and mitochondria. Above the nucleus are a prominent Golgi apparatus with large dilated vacuoles, and numerous dense inclusion bodies. Large clusters of lipid droplets and aggregations of mitochondria occupy the basal zone of the cell.The apical portion of the gland cell has fewer pinocytotic vesicles and the Golgi is smaller than in the luminal epithelial cells. Dense bodies are numerous above the nucleus. The basal portion of the gland cell is devoid of lipid, but there are often one or more enlarged mitochondria. Although a dense PAS+ substance fills the lumina of the glands, there is no obvious evidence of secretory activity in the glands during delay.The relationships of the epithelia to the environment of the blastocysts during delay is discussed.

    Notes: Die Frage, wie weit der Druckverlust eines Anströmbodens, z. B. einer Loch- oder Porenplatte, herabgesetzt werden darf, ohne daß es zu einem Durchbruch der Strömung durch das Bett kommt, ist bisher noch nicht geklärt, obwohl die Kenntnis dieses Zusammenhanges großes Interesse für die Praxis hat. Es wurden daher Versuche an Böden von unterschiedlichem Durchmesser angestellt, deren Ergebnisse zeigen, daß zwischen dem erforderlichen Mindestdruckverlust eines Anströmbodens und dem Druckverlust eines Fluidalbettes eine Beziehung besteht, die von den Betriebsgrößen des Bettes abhängt.

Das erste Problem betrifft ein hydraulisches Analogieverfahren, das erlaubt, den Einfluß des Druckverlustes der Dampfströmung an den wärmeübertragenden Elementen auf die Wärmeübertragung in einem Kondensator für niedergespannten Dampf zu bestimmen. Sodann wird eine wirtschaftlich interessante Möglichkeit diskutiert, den Irreversibilitätsgrad bei der Wärmeübertragung zu verringern, wobei das Heiz- bzw. Kühlmittel keine Phasenänderung erfährt.

In geeigneten apparativen Anordnungen lassen sich mit exothermen katalytischen Gasreaktionen auch stehende (stationäre) Brennzonen erzeugen. Sie bilden in der Katalysatorschüttung annähernd Halbkugelschalen konstanter Brenngeschwindigkeit, wie man sie auch mit den Brennflächen von Bunsenflammen im Feld einer Potentialströmung erhalten kann. Ähnlich wie umgekehrte Flammenkegel können innerhalb bestimmter Stabilitätsbereiche auch „umgekehrte“ Brennzonen erzeugt werden.  -  Auf Möglichkeiten zur Anwendung stationärer Brennzonen für spezielle Umsetzungen wird hingewiesen.

    Notes: Es wird der üblichen Helmholtz-Gouyschen Theorie der Elektrokinetik die Theorie der Aufladung schlecht leitender Flüssigkeiten in turbulenter Strömung gegenübergestellt. Bei den schlecht leitenden Flüssigkeiten verteilt sich die freie Ladung über den ganzen Rohrquerschnitt, und die Aufladung wird verursacht durch einen Diffusionsmechanismus der Ionen durch die Grenzschicht. Die diesbezügliche Rechnung ist eine Vereinfachung der von Koszman und Gavis gegebenen. Praktische Folgerungen, um bei schlecht leitenden Flüssigkeiten die statische Elektrizität zu beseitigen, werden besprochen.

Auf Grund der experimentell gesicherten hohen Wirksamkeit und der allgemeineren Gültigkeit des metallorganisch-elektrochemischen Raffinationsgeschehens wird auf die Möglichkeit der Elektroraffination anderer organophiler Metalle hingewiesen.

    Notes: Um 50proz. Silber-Münzgut elektrolytisch aufzuarbeiten, wird soviel Kupfer zulegiert, daß der Ag-Gehalt zwischen 10 und 25% beträgt. Bei der folgenden Cu-Elektrolyse in schwefelsaurer Lösung läßt sich dann das Kupfer aus der zu 5 mm dicken Anoden vergossenen Legierung herauslösen, während ein stabiles Silber-Skelett an der Anode zurückbleibt. Als Nebenprodukt werden Nickel- und Zinksulfat gewonnen. Das an der Kathode abgeschiedene Kupfer wird teilweise in den Prozeß zurückgeführt. Dieses Verfahren bietet gegenüber einer Aufarbeitung durch Silber-Elektrolyse beträchtliche wirtschaftliche Vorteile und hat sich seit fünf Jahren bewährt.

    Notes: Einige charakteristische Beispiele für die Metallabscheidung aus komplexen Elektrolytlösungen zeigen, daß die Metallabscheidung bevorzugt über Komplexe verläuft, die eine kleinere Ligandenzahl haben als das stabilste Komplex-Ion. Diese Komplexe sind vermutlich während der eigentlichen Entladungsreaktion an der Oberfläche adsorbiert. In manchen Fällen konnten parallele Reaktionswege nachgewiesen werden, von denen jeweils derjenige mit der größten Reaktionsgeschwindigkeit dominiert.

    Notes: Der geometrische Aufbau von Sieb-, Litzen- und Tressengeweben wird untersucht und durch meßbare, z. T. auch berechenbare geometrische Kennwerte beschrieben. An insgesamt 17 Gewebearten werden die Druckverluste bei isothermer Strömung gemessen. Der Beiwert für den Druckverlust aller untersuchten Gewebearten folgt im Bereich kleiner Reynolds-Zahlen einer Beziehung, die auch für poröse Festbetten gilt. Im Bereich größerer Reynolds-Zahlen weichen die Ausgleichskurven durch die Meßpunkte der verschiedenen Geweben und der porösen Festbetten erwartungsgemäß etwas voneinander ab.

    Notes: Mit der Verbrennung des Industriemülls wird ein wichtiger Beitrag zur Reinhaltung des Grundwassers und der Oberflächengewässer geleistet; denn die Abfallstoffe werden dabei in praktisch sterile Schlacke bzw. Flugasche umgewandelt, und der Gehalt der Rauchgase an schädlichen Stoffen läßt sich in den vorgeschriebenen Grenzen halten. Die erste Müllverbrennungsanlage der Badischen Anilin- & Soda-Fabrik AG hat bereits eine Betriebszeit von 24 000 Stunden hinter sich. Beim Bau einer Erweiterungsanlage wurde die durch die Produktion bedingte veränderte Zusammensetzung des Mülls berücksichtigt. Mit besonderer Sorgfalt wird die unvermeidliche Luft-Verunreinigung durch die Verbrennungsanlage verfolgt.

    Notes: Der wichtigste Teil des pH-Meßwertübertragers, der Gleichstromverstärker, wird ohne mechanische Zerhacker und Elektronenröhren nur mit einem Impedanzwandler ausgerüstet, dessen Kapazitäten infolge der Verwendung von Halbleitersperrschichten spannungsabhängig sind. Infolge dieses Aufbaues arbeitet das Gerät sehr zuverlässig. Bei Umgebungstemperaturen von  - 10 bis +50°C wird der Eingangswiderstand im Betriebszustand 〉 5 · 1011Ω, die Spannungsdrift 〈 ± 1mV und die Stromdrift 〈 10-12 A. Die kleinen Versorgungsspannungen und Ströme der Halbleiterschaltungen erlauben die eigensichere Auslegung des Ein- und Ausgangskreises oder des gesamten Gerätes, ermöglichen aber auch die Konstruktion eines batteriebetriebenen pH-Meters. Darüber hinaus ist der Verstärker allgemein anwendbar, z. B. für Ionisationskammern oder Integrationsverstärker für Rechenanlagen, also immer dann, wenn kleine Stromstärken aus hochohmigen Quellen oder kleine Spannungen leistungslos zu messen sind.

    Notes: CFl female mice were time mated and the embryos at each gestation day from 0.0 to 18.0 were x-rayed to 100 r and the young carried to four months at which time a skeletal study was made. With this exposure the litters were reduced in size, following irradiation at certain gestation ages, and there was neo-natal mortality so that this skeletal study is based upon the survivors to four months and represents the maximum development under the conditions of irradiation. The sex ratio was not altered by this irradiation. Male mice of this strain are always heavier than the females of the same age, and this exposure reduced the over-all average of either sex by 2.5 grams. The skeletal measurements were taken from 1,005 radiographs of the living animals, and the averages calculated for each gestation day. There were sex differences in stunting, even when x-irradiation occurred before day 9.0. When the differences were pronounced the female was the more adversely affected. The highest statistical significance in skeletal effects of seven measurements was between 11 and 13 days, when the embryo shows the earliest skeletal differentiation. Such mice were topographically well developed.

    Notes: The normal bovine sperm tail consists of the classical 9 + 9 + 2 fiber pattern bound anteriorly by the mitochondrial helix and posteriorly by the fibrous helix except for the last 2 to 3 μ.The outer ring of nine coarse fibers originate as laminated columns, beginning from a common base which is located in a recess at the base of the head. The fibers taper posteriorly ending at different levels in the principal piece. Evidence is presented for the alternate contraction and expansion of the laminated segments of the coarse fibers in the neck  -  the probable mechanism for initiating the flagellar wave.The mitochondrial helix is composed of several mitochondrial strands of different length. Each strand consists of several elongated mitochondria positioned end to end. Apparently the strands of mitochondria may begin or end at various locations along the middle piece. The number of turns in the mitochondrial helix was found to vary from approximately 65 to 75 turns among cells. The helix binds the axial fiber bundle with a pitch of 20 to 25° over most of the middle piece. The mitochondria are double-walled and possess internal cristae that are vesicular or tubular in structure.The fibrous helix consists of dense, circumferential strands of variable thickness and shape with two longitudinal elements on opposite sides of the helix. Both the circumferential strands and the longitudinal elements become thinner as they progress posteriorly.

    Morphologic observations concerning the release and transport of secretory products in the adenohypophysisSupported in part by United States Public Health Service Grants GM 03784 and GR-881-02. (1964)

    Notes: The processes involved in the release of secretory products from the parenchymal cells and the movement of these products into the circulating blood were studied by electron microscopic observations on the adenohypophyses of virgin estrous rabbits. The released secretory products were found in the form of discrete granules, with or without a perigranular membrane, in intercellular spaces, between the plasma membrane and the parenchymal basement membrane, in the perivascular space, in the endothelial cytoplasm, and in the lumen of capillaries. Vesicles containing material which resembled that in the perivascular space were observed in endothelial cells.Interpretation of these observations has led to the proposal of the theory that secretory products of the adenohypophysis may be liberated from parenchymal cells in the following way: by fusion of the perigranular membrane with the plasma membrane (merocrine) or by the detachment of small processes containing secretory granules (“microapocrine”). It is further believed that the discharged products may be transported into circulation in three different manners: by diffusion of dissolved material through the fenestrated endothelium, by active transport of dissolved secretory products by the endothelial cells, or by active transport of intact secretory granules through the endothelial cytoplasm.

    Structural and functional aspects of rodent salivary glands including two desert speciesThis study supported by U. S. Public Health Service grants DE-01226-03 and D-1674. (1964)

    Notes: The submaxillary glands of the adult desert rat, antelope squirrel, rat, mouse and hamster have in common low levels of amylolytic enzyme in comparison with the relatively high levels of parotid gland amylase in these rodents. Submaxillary gland acini are classed as seromucous secreting although there is some variation in the carbohydrate histochemistry of these secreting units. Granular tubules are absent in antelope squirrel submaxillary glands and they are present in the submaxillary glands of the desert rat, rat, mouse and hamster. Electron micrographs reveal the presence of numerous basal folds in the acini of antelope squirrel submaxillary and parotid glands. These structures were not observed in the salivary gland acini of the hamster. Golgi membranes and “immature” secretion granules are topographically intimate in parotid glands of the hamster and antelope squirrel. In the submaxillary glands of these two rodents, the secretory material appears to originate in relation to the endoplasmic reticulum and secondarily, the granules become associated with a diffusely arranged system of Golgi membranes. The sublingual glands of all the rodents of this study are predominantly ones that produce mucous secretion and contain well developed striated duct systems. Of the salivary glands investigated in this study, the parotid glands of the rat, mouse and desert rat produce an isotonic saliva; the saliva of the other glands is definitely hypotonic.

    Notes: Die Messung der Wärmeleitfähigkeit feuchter Bau- und Isolierstoffe bietet Schwierigkeiten und ist aufwendig. Man muß sie zwar für praktische Berechnungen im Hochbau kennen, doch würde oft eine verläßliche Schätzungsmöglichkeit genügen, da man noch Sicherheitszuschläge machen muß. Ausgehend von einem Gedanken von O. Krischer wird ein brauchbares Schätzungsverfahren gezeigt, und es werden die dafür nötigen Versuchsunterlagen mitgeteilt.

    Notes: Um im Laboratoriumsmaßstab Einkristalle von Magnesiumoxyd mit Kantenlängen bis über 1 cm zu erhalten, wird vorgesintertes MgO mit einem Kohlebogen geschmolzen. Da der Ofen selbst aus MgO besteht, ist eine Kontaminierung durch die Gefäßwand ausgeschlossen. Durch Zusatz geringer Mengen an Fremdsubstanzen, z. B. Fe2O3, MnCO3, Li2CO3, lassen sich Einkristalle verschiedener Dotierungen herstellen. MgO-Einkristalle, besonders solche mit definierter Dotierung, gewinnen wegen ihrer elektrischen und optischen Eigenschaften an Bedeutung, z. B. als Laser- und Maser-Material.

    Notes: Es wurden mit Stickstoff legierte unstabilisierte Chrom-Nickel(-Molybdän)-Stähle untesucht, die bei guten Zähigkeitseigenschaften höhere Werte der Streckgrenze und Festigkeit aufweisen als die bisherigen austenitischen Stähle. Der Nachweis dafür wurde an großen Betriebsschmelzen geführt. Diese Stähle haben einen sehr niedrigen Kohlenstoff-Gehalt und sind stabil austenitisch. Ihre Schweißbarkeit ist gut. In ihrer Korrosionsbeständigkeit unterscheiden sie sich nicht von den bisher verwendeten Stählen. Ihre Anwendung führt z. B. im Behälterbau zu geringeren Wanddicken.

    Notes: Die Korrosion von Metalien in wäßrigen Elektrolytlösungen wird vom Standpunkt der Elektrodenkinetik aus behandelt. Bei der Diskussion des anodischen Verhaltens der Metalle wird zwischen Metallen im aktiven und im passiven Zustand unterschieden. Die anodische Auflösung aktiver Metalle ist eine in mehreren Teilschritten verlaufende Reaktion an der Phasengrenze zwischen dem Metall und dem Elektrolyten. Die verschiedenen Teilschritte dieser Reaktion werden an Beispielen diskutiert. Bei einem passiven Metall trennt eine porenfreie Deckschicht das Metall vom Elektrolyten. Das Korrosionsverhalten wird weitgehend von der Deckschicht bestimmt, deren Eigenschaften besprochen werden.

    Notes: Indium wird heute vor allem für Transistoren verwendet. Es ist in Pyrit zu 1 ppm enthalten und wird bei der normalen Erzaufarbeitung zusammen mit Thallium angereichert. Von diesem wird es durch Flüssig-Flüssig-Extraktion getrennt. Zur Feinreinigung dient eine mehrstufige Elektrolyse der salzsauren InCl3-Lösung mit Hg-Elektroden, wobeidas in einer Zelle an der Kathode abgeschiedene In-Amalgam in der nächsten Zelle an der Anode wieder gelöst wird. Dabei werden Quecksilber und Elektrolyt im Gegenstrom geführt. Zur Endabscheidung dient eine Schmelzfluß-Elektrolyse des InCl, das aus dem In-Amalgam durch Einleiten von HCl erzeugt wird. Auf diese Weise werden täglich 200 g In-Metall gewonnen mit einer Verunreinigung an Hg von einigen Tausendstel Prozent.

    Notes: Kobalt läßt sich durch elektrolytische Raffination nur dann rein gewinnen, wenn diese mit anderen Reinigungsverfahren gekoppelt wird. Auch das um fast 0,5 V elektronegativere Zink wird bei der Kobalt-Elektrolyse mitabgeschieden. Bei hohen Zink-Gehalten der Ausgangsstoffe, wie sie z. B. bei der Duisburger Kupferhütte vorliegen, ist daher eine Elektrolyse mit löslichen Anoden zweckmäßig, da beim Calcinieren des als Zwischenprodukt gefällten Kobalthydroxyds und beim reduzierenden Schmelzen des Kobaltoxyds im Elektroofen Zink verflüchtigt wird. Die Duisburger Kupferhütte raffiniert eisenreiches Kobalt, das bei der Aufarbeitung der Kobalt-Raffinationsschlacke erhalten wird, durch eine Elektrolyse mit löslichen Anoden und Diaphragma.

    Notes: Die Eigenschaften galvanischer Metallniederschläge (Glanz, Härte, Polierfähigkeit) werden von den Abscheidungsbedingungen (Stromdichte, Spannung, Art der Salze und Zusätze, pH-Wert, Temperatur) beeinflußt. Bei der Nickel-Abscheidung ist der Oxydgehalt durch ein Nickelhydroxyd vom C6-Typ bzw. Brucit-Typ (β-Form) bedingt. Außerdem wird ein βαNickelhydroxyd der idealisierten Formel 3Ni(OH)2 · 2H2O abgeschieden. Diese α-Form ist löslicher als die β-Form und läßt sich auch aus Lösungen mit sehr verdünnter Lauge ausfällen und durch mehrwertige Alkohole stabilisieren.

    Notes: Thioharnstoff-Zusätze zu sauren Verkupferungsbädern verbessern die mechanischen Eigenschaften der abgeschiedenen Schichten. Der Thioharnstoff kann in Form seines Cu(I)-Komplexes spektrophotometrisch im UV-Bereich bestimmt werden. Dieser Komplex verschwindet bei der Elektrolyse schneller aus dem Anoden- als aus dem Kathodenraum. Elektronenmikroskopisch ließ sich zeigen, daß bei zwei nacheinander mit dem gleichen Bad erhaltenen Schichten die mittlere Korngröße zunimmt, während Verteilungsdichte und mittlerer Durchmesser der Einschlüsse sich kaum verändern. Die Zunahme der Korngröße im Verlauf der Elektrolyse wurde auch innerhalb einer einzigen Schicht nachgewiesen.
