A case of dysplasia eplphyseaalis hemlmelica (Fairbank, 1956) in a 8 years old boy, showlng typical clinical and roentgenographical appearance, is reported together wlth a brief review of literature in this paper. This condition is a rare developmental disorder of childhood in which there is a asymmetrical cartilaginous overgrowth of one or more than one epiphysis, or of a tarsal or carpal bone. Thls disorder is usually Iimited to elther the medial or lateral half of a single extremity. The disease is characterised radiographically by delay in the appearance of the epiphyseal nucleus, which is mottied and of irregular density. The most common deformities were genu valgum or varum and valgus or equinus deformity of the ankle. These deformities tended to increased wlth growth but the size of the lesion increased in proportion to the growth of the normal bone. Concomitant involvement of the knee and ankle is the rule, and in those cases the affected limb Is usually longer than Its mate. The lesion Is often microscopically indistingulshable from an osteochondroma.

The influence of normal late pregnancy on insulin action and insulin secretion was studied in the Sprague-Dawley female rats. On 20th day after mating, intravenous glucose tolerance test(IVGTI) was performed in non pregnant control and pregnant rats. As results of IVGTT, glucose disappearance rate was not significantly different in both groups, but secretory response of insulin was significantly(p<0.05) increased in pregnant rat. And the ratio of insulin/ .glucose was significantly higher in pregnant rats, which means existence of insulin resistance. These insulin resistance was overcomed by increased secretory response of pancreatic insulin. Insulinogenic index( A insulin/glucose - 5 min) was highly significantly (r=0.62, p<0.01) correlated with progesterone concentration. Glycogen level and amounts of "C-glucose incorporated into glycogen after IVGTT were significantly(p<0. 05) decreased in the liver, but were not changed significantly in soleus. Glycogen synthase activity of soleus and liver was not differ significantly in the both groups. Insulin binding at varying concentrations of insulin to crude membrane of pregnant liver was not significantly different from control. In conclusions, although these pregnant rats were normal glucose tolerance due to increased secretory response of insulin, that was correlated with progesterone concentration, pregnant rat had insulin resistance. The mechanisms of insulin resistance were not related to defect of insulin binding phase and glycogen synthase, but suggest pre-receptor and/or postreceptor phase.

The effect of exercise on plasma insulin, free fatty acid, and glucose uptake and glycogen concentration in soleus, and intravenous glucose tolerance of streptozotocin treated, diabetic Sprague-Dawley rats were studied. Diabetic-trained animals were subjected to a regular program of treadmill running for 4 weeks. Seventy-two hours after the last training session, basal and insulin-stimulated glucose uptake was studied in incubated strips (about 20 mg) of soleus muscle in vitro. Glucose tolerance was measured with intravenous infusion of 0.5 g glucose/kg body weight. In diabetic rats, training was associated with increase glucose uptake in basal and maximal insulin concentrations, decreased fasting glucose concentrations, and increased muscle glycogen levels, but there were no changes in glucose tolerance curve and plasma insulin concentrations. These results suggest that regular running program for 4 weeks improve responsiveness of insulin on soleus muscle, but fails to cause improvement of impaired intravenous glucose tolerance in mild degree streptozotocin induced diabetic rats.

During development of central nervous system, cell proliferation, cell migration, cell differentiation and cell death are required. It has been reported that a number of cells are dying during development in the mammalian retinae examined so far, but the pattern of cell death has not been clarified yet. In addition. little has been studied on cell proliferation after birth. This study was conducted to identify histogenesis, cell death and cell proliferation in the retinae of the developing rats by light and electron microscopic methods as well as by immunohistochemical method using anti-proliferating cell nuclear antigen [PCNA] antiserum. The results were as follows : 1. In the developing rat, from postnatal 0 through 7 days, retina consisted of ganglion cell layer, inner plexiform layer and neuroblast layer. Neuroblast layer could be subdivided into three sublaminae : sublamina a, sublamina b and sublamina p, from postnatal 3 through 7 days. 2. From postnatal 10 days, retina consisted of ganglion cell layer, inner plexiform layer, inner nuclear layer, outer plexiform layer and outer nuclear layer. 3. Cells undergoing degeneration were observed from postnatal 0 to 13 days, and patterns of cell death were apoptosis, cytoplasmic degeneration and autophagic degeneration. 4. PCNA-immunoreactivity was seen in the cells located in sublaminae b and p of the neuroblast layer at postnatal 0 and 1 days. From postnatal 3 days PCNA immunoreactivity decreased. At 7-day-old rat, PCNA-Immunoreactive cells scattered in the distal part of sublamina p of the neuroblast layer.No immunoreactivity was observed from postnatal 10 days. These results demonstrate that retinal cell proliferation ends at postnatal 7 days, and histogenesis of retina is completed at postnatal 10 days, and superfluous cells during retinal development are eliminated by apoptosis, cytoplasmic degeneration and autophagic degeneration.

Traditionally, evaluation after ACL reconstruction has been focused on physical characteristics and measures of knee stability. Recently, however, reliance on such criteria has been refuted based on the lack of a strong relationship between these measures and both the patient s perception of knee function and return to sports activity. In present study, preoperative and postoperative physical examinations, isokinetic dynamometer, arthrometer test and functional tests were performed on 17 patients with chronic anterior cruciate ligament tears treated by arthroscopic reconstruction using autogenous bone-patellar tendon-bone graft with at least 1 year of follow-up. Muscle power, joint stability and functional recovery were checked for functional evaluation by specific methods. Lysholm score rating scale and functional tests (single leg hop test, vertical jump test, timed single jump test) were performed preoperatively and 6, 12 months postoperatively. Pivot-shift test, Lachman test, anterior drawer test, thigh circumference index and Cybex II+ isokinetic dynamometer test were done preoperatively and at 3, 6, 12 months postoperatively. KT-2000 arthrometer test was done at last follow-up. Lysholm score has showed increasing tendency at 6, 12 months postoperatively (p < 0.01). In Cybex study, deficit percentage of peak torque and total work of the quadriceps and hamstrings was same or slightly decreased at 3, 6 months, but have decreased at 1 year follow-up (p < 0.01). Functional tests and physical examinations have also showed improving tendency at 12 months (p < 0.01). Arthrometer test revealed no significant laxity of the knee joint at last follow-up. In conclusion, muscle strengh and functional capacity in ACL reconstructed knee showed significant improvement at postoperative one year compared with preoperative status. It was considered that arthroscopic reconstruction using autogenous bone-patellar tendon-bone graft is one of the useful method for chronic anterior cruciate ligament injury.
