    Notes: Most fish have a diffuse exocrine pancreas located around the internal organs, but its exact structure is not well understood. In this study, we developed a method for analysing zymogen granules using anti-fish trypsinogen, and the structure of the flounder pancreas was examined by localizing pancreatic exocrine cells. Anionic trypsinogen was purified from eel pancreas by chromatography using DE-52-cellulose and Superose 12 columns. Rabbit antiserum (anti-eel trypsinogen antibody: anti-eTrg) was raised against purified trypsinogen. Immunoblotting analysis demonstrated that anti-eTrg recognized two isoforms of eel trypsinogens and trypsins. This antibody also reacted with flounder trypsin. Zymogen granules containing trypsinogen were visualized within pancreatic glandular cells of the flounder Paralichthys olivaceus by immunohistochemistry using anti-eTrg. The flounder exocrine pancreas was reconstructed from observations of serial sections of digestive tract. The exocrine pancreas cells were localized along the hepatic portal vein and the veins running to the portal vein from the intestine, stomach, pyloric appendage and spleen, forming a highly branched tissue. Interlobular ducts from pancreatic acini formed a pancreatic duct covered with smooth muscle at the point where it met (but did not join) the bile duct. The pancreatic duct opened into the intestinal lumen at the basal portion of the third pyloric appendage in parallel with the bile duct.

    Notes: We demonstrate optical response from a side-injection light-controlled bistable laser diode buried with semi-insulating InP using hydride vapor phase epitaxy. The buried surface around both the 〈110〉 and 〈−110〉 oriented mesas is flat. The bistable operation is obtained by applying control voltage to the saturable absorption region. After optimization of the device parameters, we obtained error-free operation at a bit rate as high as 2.5 Gbit/s. © 1997 American Institute of Physics.

    Notes: Vertical-cavity surface-emitting laser (VCSEL) structures have been grown on GaAs (311)B substrates by metalorganic chemical vapor deposition. C-doped GaAs and AlAs layers with smooth surface morphology and a hole concentration of 1018 cm−3 were obtained by optimizing the growth conditions; these conditions contributed to high-quality p-type distributed Bragg reflectors (DBRs). The devices on the (311)B substrates exhibited a threshold current of 9.6 mA, voltage of 2.1 V, and maximum power of 4.1 mW at a 20 μm φ size; these characteristics are similar to those obtained on (100) substrates. The polarization was aligned to [2¯33¯]. © 1997 American Institute of Physics.

    Notes: Abstract. Bone lengthening by callotasis is one of the most useful methods not only for the treatment of short extremities but also for extensive bone defects; however, the procedure takes a long time especially for the consolidation of the distracted callus. In this study, effects of a single local injection of recombinant human fibroblast growth factor-2 (FGF-2 or basic FGF) on callotasis bone lengthening were examined in rabbits. Ten days after the osteotomy at the middle of the tibia and the installment of an external fixator, the osteotomized site was distracted at a rate of 1.4 mm/day for 7 days, resulting in 9.8 mm lengthening. On the final day of distraction, 200 μg of FGF-2 in 150 μl of saline solution or vehicle alone was injected into the center of the distracted callus. Injection of FGF-2 increased bone formation at the distracted callus radiologically and histologically. A significant effect on bone mineral content (BMC) at the callus was observed as early as 2 weeks, and FGF-2 increased the BMC about twofold at 5 weeks after a normal remodeling process. We conclude that the callotasis method in combination with FGF-2 injection at the consolidation step could be clinically beneficial to shorten the bone lengthening period.

    Notes: Abstract The effect of basic fibroblast growth factor (bFGF) applied locally into the bone under physiological conditions was investigated. An aqueous solution containing Oμg (vehicle), 100 μg or 400 μg recombinant human bFGF was percutaneously applied through a needle into the right ilium in rabbit, and the ilia were harvested 4 weeks after the application. Compared with vehicle-treated animals, bone mineral density measured by dual-energy X-ray increased in the 400 μg bFGF group. The width of trabeculae in the bFGF-treated groups was greater than in the vehicle group. These results showed that bFGF applied locally into the bone under physiological conditions affected bone formation, and suggested that such an application might have potential for increasing bone.

    Changes of callus diameter during axial loading and after fixator removal in leg lengthening (1998)

    Notes: Abstract We retrospectively reviewed nine tibial lengthenings in seven achondroplastic patients. The callotasis method was used, and a unilateral type lengthener, either the Dynamic Axial Fixator (Orthofix, Italy; eight legs) or the High Functional Fixator (Matsumoto Co., Japan; one leg), was applied. The distracted length averaged 14.6 (range 10–18) cm. The minimum diameter of the callus was measured using a ruler on anteroposterior and lateral radiographs. The callus diameter ratio (%) was calculated as the callus diameter divided by the original diaphysis diameter. For periods during axial loading and after removal of the fixator in each patient, a single regression line was drawn on the callus diameter ratio data using the least squares method, and the diameter change rate (%/day) was evaluated by inclination of this line. The diameter change rates during axial loading were negative in six legs, but those after fixator removal were positive in all legs, and the latter were significantly greater than the former. The diameter change rates after fixator removal on the anteroposterior radiographs were negatively correlated with the callus diameter ratio at the time of fixator removal (r = 0.84, P = 0.0008). Simple axial loading may not be a sufficient mechanial environment for restoration of the physiological shape, and it is important to be aware that we cannot expect the callus diameter to increase by this means alone.

    Notes: Abstract Spondyloepiphyseal dysplasia congenita (SEDC) can be accompanied by hypoplasia of the odontoid and/or lax ligaments which may lead to spinal cord compression. Since an early diagnosis of myelopathy is essential for rational treatment, identification of the high-risk factors is imperative. Sixteen patients were retrospectively reviewed, 10 male and 6 female, and their average age at the time of examination was 18 (range 3–37) years. Myelopathy was seen in 6 individuals. Five were associated with atlantoaxial subluxation, and the critical value of space available for the spinal cord at the level of the atlas was 10 mm or less. Their height was less than –7SD of average Japanese of the same age, and all were associated with severe coxa vara. Although SEDC itself is a risk factor, marked short stature of less than –7SD and severe coxa vara are particularly high-risk factors for cord compression at the level of the atlas.

    Notes: Abstract The cardinal feature of Maffucci syndrome is the coexistence of enchondromatosis and vascular anomalies. The patients are usually normal at birth, the disease becoming evident at any time up to puberty. Association of soft-tissue swelling has been described in this syndrome but has not been listed as a sign or symptom. We report three cases in which the initial sign was diffuse swelling of the dorsum of the hand and/or foot. This was noticed at birth in cases 1 (girl) and 3 (girl) and at the age of 1 month in case 2 (boy), who otherwise appeared normal except for case 3 who had a rectovestibular fistula. The pathology of the swollen soft tissue was adipose tissue associated with various degrees of thickened and fibrotic septum containing dilated lymphatic channels. These dilated channels within the septum were so subtle that they were initially overlooked in cases 1 and 2. Awareness that swelling of the dorsum of the hand or foot can be the sole sign and symptom of Maffucci syndrome before the typical indications become evident helps the physician establish an early diagnosis of this condition.

    Familial occurrence of hyperplastic callus in osteogenesis imperfecta (1997)

    Notes: Abstract There is a hypothesis that hyperplastic callus (HC) in osteogenesis imperfecta (OI) is not merely a rare complication but could actually be inherited, although this idea has not yet been investigated. We described two cases, a mother and son, with mild OI, normal scleral colour and no dentinogenesis imperfecta, who repeatedly had HC in their femur. Familial occurrence of HC was found in 13 cases in 5 families among 21 cases in 7 families with a familial background of OI in the literature (including this report). This is higher than the reported incidence of HC, 1.5% (5 cases of 333), and the mode of transmission is concomitant with autosomal dominant inheritance in all these families. Since a review of 47 cases in the literature shows that HC occurs independently of scleral colour and the degree of bone fragility, it may be an additional criterion for subdivision within each type of the Sillence classification.
