    Notes: Summary 1. Within the cat geniculate ganglion three distinct neural populations were definable on the basis of single unit recordings. These three neural populations were designated “ear units”, “regular discharge units” and “tongue units.” Units from these three populations tended to be located in different regions of the ganglion and were influenced by different types of stimulation to different parts of the body. 2. Ear units seemed to constitute a uniform functional population, with the major differences between units being the external locus of projection. Ear units typically had no spontaneous activity. They were discharged by dynamic displacements of hairs on the skin of the inner surface of the ear. 3. Regular discharge units were classified into three types on the basis of their spontaneous activity patterns. Discharge of most of the units could be affected by static dislocations of tissues of the soft palate and pharynx. Discharge patterns, evoked and spontaneous, tended to be extremely regular. 4. Tongue units seemed to constitute an extremely diverse population. Wide variability was shown on every measure taken of tongue unit activity. Spontaneous activity patterns varied markedly from unit to unit, with bursting discharge common. Most units could be discharged by electrical stimulation of papillae of the tongue, although the number of stimulatable papillae varied from unit to unit as did latency measures. Some tongue units were discharged by mechanical stimulation of the tongue, most by chemical stimulation of the tongue (with salt, acid, quinine and common cat foods), and some by both.

    Notes: Poly-4,4′-oxydiphenylenesulfonyl and poly-4,4′-methylenediphenylenesulfonyl were synthesized by an electrophilic substitution polymerization of the arylene monosulfonyl chloride monomers. The glass-transition temperatures Tg of these polymers were determined by calorimetric and dynamic mechanical measurements, and the number-average molecular weights were determined by vapor-pressure osmometry. Both polymers were found to have the same Tg at equivalent molecular weight; the limiting value at high molecular weight is 238°C. Both polymers have two dynamic mechanical relaxation peaks at temperatures far below Tg. One is in the neighborhood of 0°C, and the other is at -110°C. Plausible origins for these relaxations, and the absence of any near 0°C in poly(4,4′-isopropylidenediphenylene-co-4,4′-sulfonyldiphenylene dioxide), are discussed.

    Notes: Horseradish peroxidase was injected into the spleens of mice and the animals were sacrificed ten minutes after injection. The tissues were reacted with 3-3′ diaminobenzidine hydrochloride and the distribution of the reaction product was studied with both the light and electron microscope. The peroxidase was localized between epithelial cells up to the region of the tight junction and within vacuoles in the absorptive cells Granules ranging in size from ca. 40A to 600A were observed in the cytoplasm of epithelial cells in numbers far in excess of that found in control specimens. It appeared that the diffuse light brown staining observed in epithelial cells with the light microscope could be attributed to large numbers of granules of reaction product free in the cytoplasm. When corn oil was given by stomach tube and an intravascular injection of perioxidase was given ten minutes later, absorbed lipid was found to pass from interepithelial cell spaces to lamina propria at the same time that peroxidase was traversing the same compartments in the reverse direction. Hence, it was shown that exogenous peroxidase and probably other substances of vascular origin required for the metabolism of epithelial cells are exposed to both the basal and lateral epithelial cell membranes, even when absorbed lipid is traversing the same spaces in the opposite direction.

    A morphological and histochemical study of the primary and secondary immune responses in the rat spleenThis project received support from a General Research Support Grant to the University of Wisconsin Medical School from the National Institutes of Health, Division of Research Facilities and Resources.

    Notes: Macrophages and cells of the plasmocyte series were studied in the rat's spleen during the primary and secondary immune responses to particulate antigen. Evidence is presented to suggest that the plasma cell precursors are located in the marginal zones surrounding the lymphoid nodules and that less than one day following injection of antigen, these cells migrate into the nodules, where mitosis and subsequent differentiation into hemocytoblasts occurs in the presence of nodular macrophages. The hemocytoblasts then migrate across the marginal zone into the red pulp where differentiation into mature plasma cells occurs in the presence of red pulp macrophages. It is suggested that the initiation of the antibody-forming process occurs in the lymphoid nodules where marginal zone cells come into close contact with the marginal metalophils or with germinal center macrophages. The process initiating the migration of cells from the marginal zone to the nodules is unknown.

    Marginal zone and germinal center development in the spleens of neonatally thymectomized and nonthymectomized young ratsThis project received support from a General Research Support grant to the University of Wisconsin Medical School from the National Institutes of Health, Division of Research Facilities and Resources.

    Notes: Spleens from neonatally thymectomized and nonthymectomized young rats were studied histologically and histochemically to elucidate the development of the splenic immune system with and without thymus.In intact animals primitive germinal center activity could be elicited with antigen as early as 13 days of age. More definitive germinal centers lacking tingible body macrophages were observed at 18 days of age. Germinal centers containing tingible body macrophages did not develop until 35 days of age in response to antigenic stimulation. This coincided with maximal development of the marginal zone of medium-sized lymphocytes and the mature development of nodular macrophages possessing strong acid phosphatase activity.Neonatally thymectomized rats developed marginal zones and germinal centers similar to control littermates when the young animals were maintained on tetracycline. Thymectomized animals not given tetracycline showed disturbances in splenic development. These are discussed.The results suggest that the thymus may be critical to the immune system in rats from birth to about 30 days of age but is not essential to its function beyond this period. Marginal zone lymphocytes and germinal center cells proliferate normally and mature to the plasma cell stage in the absence of a thymus if the animals are maintained on tetracycline beyond this critical age.

    Notes: Liver mitochondria from normal and alloxan diabetic rats, isolated in 0.25 M sucrose, were assayed with an oxygen electrode for ADP/O and Ca+2/O ratios, respiratory ratio, and respiratory control index. Mitochondria were incubated with two substrates, succinate and β-hydroxybutyrate; two types of ionic media, Na+ medium (Na+ the major monovalent cation) and K+ medium (K+ the major monovalent cation); and two respiratory stimulants, ADP (352 μM) and Ca+2 (187 μM). Significant differences between respiratory rates and ADP/O ratios were dependent upon the substrate and ionic medium employed. The results confirm previous studies which showed no alteration in ADP/O ratio but decreased State 3 respiratory rates under similar conditions of K+ medium with ADP stimulation in the diabetic. Furthermore, the State 3 respiration was prolonged compared to normal. Ca+2 stimulation was the same in normal and diabetic mitochondria in K+ medium. Studies in Na+ media revealed more significant differences in RCI's, respiratory rates, and ADP/O ratios that were substrate dependent as well as ion dependent. The results from these various studies can be accounted for by an hypothesis linking mitochondrial K+ interaction with alterations in the diabetic mitochondria.

    Notes: As model polymers for isolated short-chain branches in low-density polyethylene, a series of ethylene-1-olefin copolymers was examined by use of 13C NMR at 25.2 MHz. An array of 13C resonances was observed that could be associated independently with methyl through amyl branches. The 13C chemical shifts became insensitive to branch length with hexyl and longer branches. Assignments of the various carbon resonances associated with branching were accomplished by using off-resonance decoupling techniques and the behavior of alkane chemical shifts previously observed by other investigators. The ratio of certain backbone and branch resonances could be used to establish the short-chain branch distribution in a low-density polyethylene.
