The normal criteria of the ankle joint laxity of the Korean may be different from that of the western. For the objective study, we designed two devices for the anterior drawer test and inversion stress test. Using the devices we radiologically examined the 120 ankle at neutral and 30 plantar flexed position. The following results were obtained; l. In the talar tilt angle, the minimun angle, the maximun angle and the mean were 1.0°, 12.0°, 3.7° respectively at the neutral position and 1.0°, 19.0°, 4.8° respectively at the 30° plantar flexed position. 2. With the Grace method, the minimum distance, the maximum distance and the mean were 3.Omm, 12.0mm, 5.2mm respectively at the neutral position and 3.0mm, 12.6mm, 6.1mm respectively at the 30 plantar flexed position. 3. With the Kelikian method, the minmum value, the maximum value and the mean were Omm, 7.5mm, 2.2mm respectively at the neutral position and Omm, 8.0mm, 2.5mm respectively at the 30 plantar flexed posion. 4. There was no difference in laxity for the age and sex.

In order to evaluate the ocular autonomic dysfunction in diabetics, pupil cycle time(PCT) was assessed in 201diabetics and 33controls. PCT was significantly different between the diabetics and controls and prolonged in diabetics in regard to the severity of retinopathy(p<0.05). PCT was significantly prolonged in diabetics in regard to the diabetic peripheral neuropathy and nephropathy(p<0.05). PCT was significantly different among the diabetic groups in regard to the duration of diabetes(p<0.05). Sustainde PCT was unmeasurable in 56.7% of diabetics and in 72.3% of proliferative diabetic retinopathy compared with 28.8% of controls(p<0.05). Ocular autonomic dysfunction in diabetics correlated closely with the severity of the diabetic retinopathy, diabetic petiphetal neuropathy and nephropathy, diabetic duration.

In order to investigate the cumulative incidence and risk factors for diabetic retinopathy among non-insulin dependent diabetes mellitus, 116 patients which given diagnosis of diabetes at age 30 years or older who had been followed-up for more than 10 years and were initially free from retinopathy were analysed retrospectively. Several risk factors for retinopathy were analysed at the initial examinations: sex, age at the onset, age at the initial examination, duration, fasting plasma glucose(FPG), two-hour postpradial plasma glucose(pp2), blood pressure, hypertension status, therapeutic regimen, total cholesterol, HDL-cholesterol, triglyceride, body mass index. After a mean follow-up time of 11.7 years. The cumulative incidence was 31.0%. By univariate analysis. Significant risk factors of retinopathy were age at the onset, age at the initial examination. FPG, PP2, therapeutic regimen. However, By using multivariate analysis. Independent risk factors were not found.

It is well known that the medullary carcinoma of the breast is one of the special types of breast carcinoma with a good prognosis. At present, the medullary carcinoma of the breast is subclassified into 3 types: typical medullary, atypical medullary and nonmedullary carcinoma. Among them, the former has the best prognosis. We reviewed the film mammographic and ultrasonomammographic findings of 13 patients according to the reevaluated histopathologic diagnosis. Typical medullary carcinoma shows a well circumscribed mass with surrounding halo on film mammogram, and well defined mass with central intermediate echogenicity and peripheral low echogenicity and posterior acoustic enhancement on ultrasonomammogram. Atypical medullary carcinoma shows relatively well circumscribed mass with partial marginal obliteration on film mammogram, and irregular bordered mass with inhomogeneous echogenicity due to focal necrosis in the mass and associated findings of thick boundary, asymetrical lateral shadowing on ultrasonomammogram. Nonmedullary carcinoma shows lobulated mass with surrounding parenchymal distortion and skin thickening on film mammogram, and relatively well defined lobulating mass with surrounding parenchymal distortion and marked heterogeneous internal echogenicity on ultrasonomammogram. Therefore, differentiation between typical medullary carcinoma with good prognosis and atypical medulary or nonmedullary carcinoma with poor prognosis, may be possible by various diagnostic imaging modalities preoperatively. But further collective study shall be needed in near future.

OBJECT: This study was carried out to investigate the effect of pentoxifylline on in vitro fertillization and developmen of preimplantation stage of mouse embryos. MATERIAL AND METHODS:F1 hybrid mice was superovulated with PMSG/hCG and mouse oocytes were recruited. After the normal sperms were incubated with PTX before in vitro fertilization, it was observed whether the fertilization and embryo development was affected or not by the sperm preparation(washing, dilution and no washing or no dilution). And after 1-cell and 2-cell stage of mouse embryos were incubated with PTX, the development to hatching blastocyst was also observed. RESULTS: When in vitro fertilization was revealed by using the washed normal sperms after 0, 3.6 and 7.2 mM PTX incubation, the fertilization rates were 92.5%, 48.8%, 36.8%, respectively. So 3.6 and 7.2 mM groups presented significantly low fertilizatin rate, but the development rates were 93.9%, 85.0%, 95.2%, respectively. Therefore, there were no significant difference between each group. When in vitro fertilization was revealed by using the diluted normal sperms after 0, 3.6, and 7.2 mM PTX incubation, the fertilization rates were 58.6%, 5.4%, 9.4%, respectively. So 3.6 and 7.2 mM groups presented significantly low fertilization rate. The developmental rates were 88.2%, 100%, 100%. And there were no significant difference between each group. When in vitro fertilization was revealed by using the not washed and not diluted normal sperms after 0, 3.6 and 7.2 mM PTX incubation, the fertilizatin rates were 61.2%, 5.7%, 3.8%, respectively. 3.6 and 7.2 mM group presented significantly low fertilization rate. The development rates were 73.3%, 0%, 0%, respectively. So 3.6, 7.2 mM group presented significantly low developmental rate. After 1-cell stage of mouse embryos were incubated in 0, 5, 10, 50 nM of PTX, the development rates were not significantly different among them. After 2-cell stage of mouse embryos were incubated in 0, 5, 10, 50 nM of PTX, the development rates were not significantly different among them. CONCLUSION: In conclusion, when PTX is used in in vitro fertilization program with normal sperms, it may affect the fertilization and embryo development in high concentration. And if PTX concentration is very low, the developmental rate would not be affected. So PTX must not be used to normal sperms and where use of PTX is indicated, it is recommended that remainder PTX must be removed as completely as possible.

It is well-known that the infection of bone and joints could produce the shortening by destroying the articuiar cartilage and growth plate, or the lengthening hy increased hlood circulation to the epiphyseal and metaphyseal regions of long bone. Since 1985, we have treated total l7 cases of children s pyogenic or tuberculous children s knee with early arthrotomy and continuous irrigation etc. and followed their long hone growth for average 53 months after surgical intervention. Five patients (group I ) were early treated within 2 weeks and twelve patients(group 3 ) were delayed to treat their knees for more than 2 weeks of symptom development. Total 11 patients out of 17 cases(64.7%) (2 cases of group 1 pyogenic arthritis, and 1 case of group l and 8 cases of group II tuberculous arthritis) revealed growth acceleration. Femoral lengthening was much more greater than that of tibial growth, and the size of patella, distal femoral and proximal tibial epiphysis which were measured by computerized digitizer were also significantly larger than that of opposite knee. The total limb length was increased hy average 7mm in 6 months, l4mm in 1 year and 3mm in 2 years after operation. These results suggest the pyogenic and tuberculous arthritis in children s knee should he treated as early as possible after symptoms developed, and followed them to trace their limh inequality for at least 2 years after surgery. That means the early arthrotomy for tuberculous knee or even in pyogenic arthritis can preserve normal articular cartilage and can also prevent the early epiphyseal closure hy infection. and can get the limh lengthening by increased blood circulation around the knee joint.
