At the time in vitro fertilization and embryo transfer, patients with unsuitable endometrium recovered by hormone. However, the overtreatment of hormone causes indispositionly the uterus internal secretion and finally induces endometriosis. Therefore, this study was done to inverstigate the effects of interleukin-2, which was known to differentiator and proliferator of T cells, on proliferation of the endometrial stromal cells in vitro. We have exammined the effects of interleukin-2, on the proliferation of bovine endometrial stromal cells in vitro, assessed by ['H]-thymidine incorporation and MTT assay methods. Results indicate that we isolated endometrial stromal cells from bovine uterus and established in vitro culture system. And interleukin-2 showed distint stimulatory effect on proliferation of the established stromal cells. These stimulative effects were not affected by estrogen and progesterone indirectly. In conclusion, these data imply that interleukin-2 may proliferate bovine endometrial stromal, cells, and it provides clue for understanding of direct actions of cytokines on the endometriat cells.

Livedo reticularis is a mottled bluish discoloration of the skin which occurs in a netlike pattern and is not a diagnosis in itself, but is a nonspecific reaction pattern. It may be classified as idiopathic and secondary livedo reticularis. Decompression sickness can occur during decompression after diving into deep sea water or during a rapiid ascent from sea level, and is one of the many causes of the secondary livedo reticularis. We report a case of livedo reticulris which developed in a patient with decompression sickness. A biopsy from the purpuric patch revealed an unusual histopathologic finding that resembles those of bullae and sweat gland necrosis in drug induced coma.

The use of the interlocking intramedullary nails expand the possibilities for treatment of femoral shaft fractures, as illustrated by consistent and satisfactory clinical results. However, the technique is relatively complex compared to conventional nails and frequently poses technical problems. A retrospective review was undertaken of twenty-eight patients with femoral shaft fractures which had technical problems after undergoing the closed reduction and internal fixation with interlocking intramedullary nail procedure. We studied the types of the problems. Their causes, the frequency of problems with various kinds of nails, and discussed solutions of the problems. There were 21 additional comminutions and intraop erative splinterings, 8 angular deformities, 3 malpositioned nails, 3 loosened distal locked screws, 2 brocken drill bits, and 1 femoral neck fracture. Bone-union was attained in all cases (28 patients), but the period of treatment to attain bone-union was protracted to an average of 6.8 (5-12) months. In 3 cases, the knee joint range of motion was of limited flexion, 70 to 90 degrees, but in all other cases full range of motion was realized. 7 cases required 2 or more operations. The hospitalization period was for an average of 3.6 months. In conclusion, the importance of careful preoperative planning and experienced surgical technique cannot be overemphasized because we could see no significant difference in the occurence of technical problems in several kinds of the nail.

The recent trend in method of long bone fracture had been toward bracing or closed medullary nailing except for certain fractures that fall within well-established surigcal criteria. Functional bracing is gaining widespread acceptance in management of tibial, femoral, and forearm fractures and is well suited to humeral shaft fractures. Twenty four cases of humeral shaft fractures were treated with functional brace and early mobiliza tion from October 19S2 to June 1984 at Busan National University Hospital and the results were as follows. 1. The fracture sites were composed of middle third in 15 cases, distal third in 6 cases, and proximal third in 3 cases and the fracture shapes were transverse in 10 cases, oblique and spiral in 5 cases respectively, and comminuted in 4 cases. 2. The average time from injury to functional bracing was 13.0 days and to discontinuance of the functional brace was 9.0 weeks. 3. Nonunions have not been encountered in all cases. The residual angulation was under 20degrees in all but one and the most common deformity was varus in 20 cases. Minimum limitation of motion, mostly a loss of the last few degrees of external rotation, was detected after follow-up of 2 months but did not present any clinical problem. 4. The achievement of rapid and uninterrupted osteogenesis without undesirable functional or cos- metic deficit could be listed as the advantage.

We report a case of Hunter's syndrome in an 8-year-old boy, who presented with ivory-white colored papules and ridges on the left chest area, which were regarded as pathognomonic cutaneous markers for Hunter's syndrome. He also showed growth retardation, dear corneas, hepatosplenomegaly and fair intellect. The histopathological findings of papular lesions revealed loosely arranged collagen fibers with massive mutinous material which stained positively with alcian blue at both pH 2.0 and 0.5. On quantitation of glycosaminoglycans by hexuronic add assay in 24-hour urine, excessive excretion of creatinine was noted. To the best of our knowledge, this is the first case in Korea.

OBJECTIVE: Our present studies were conducted to examine more effective isolating method of preantral follicles from mouse ovaries. METHODS: ICR mice (3-6 weeks old) were sacrificed through cervical dislocation and their ovaries were removed and put into watch glasses containing Hams F-10 supplemented with 10% fetal bovine serum (FBS). Preantral follicles were isolated by three different methods; 1) enzymatical method and 2) mincing method, and 3) scraping method. Enzymatical method was carried out as following. Ovaries were bisected with a pair of fine 30G needles. Bisected ovaries were incubated at 37degrees C and 5% CO2 incubator in 2-well dish containing Hams F-10 supplemented with collagenase 600 IU/ml. After 20 min.,follicles were isolated by repeated pipetting. Isolated preantral follicles were collected, and the remnant of tissues was placed in incubator and previous procedure was repeated. Mincing method was carried out with a pair of fine 30G needles attached to 1 ml syringes and mined ovary. Scraping method was carried out wit a pair of fine 30G needles and scratched to surface of ovary. The differences between isolating methods were analyzed using Student's t-test and Chi-square. Results were considered statistically significant when P value was less than 0.05. RESULTS:In handling time, mincing or scraping method (28+/-3.42 min or 16+/-1.58 min) were significantly (p<0.00001) shorter than enzymatical method (72+/-1.69 min), and scraping method was significantly (p<0.01) shorter than mincing method. Total number of isolated follicles was significantly (p<0.0001) higher in enzymatical method (49.8+/-3.91) than in mincing or scraping method (25.3+/-2.33 or 20.5+/-1.75). Isolated follicles in < or =90 micrometer were significantly (p<0.005) higher in enzymatical method (15+/-1.71) than in mincing or scraping method (7.8+/-0.98 or 8.1+/-1.31). In 91~130 micrometer, isolated follicles were significantly (p<0.0005) higher in enzymatical method (33+/-3.27) than in mincing or scraping method (16.3+/-1.82 or 10.7+/-1.38). In > or =131 micrometer, isolated follicles were not significantly differences between all groups. In equal sizes, the rate of isolated follicles in < or =90 micrometer was highest in scraping method (39.6% vs. enzymatical method:30.1%, p<0.05; mincing method: 30.9%, p=0.11719, NS). Rate of follicles in 91~130 micrometer was significantly (p<0.05) lower in scraping method (52.7%) than in emzymatical or mincing method (66.3% or 64.5%). Rate of follicles in > or =131 micrometer was highest in scraping method (8.3% vs. enzymatical or scraping method: 3.6%, p<0.05)or 4.6%, p=0.19053, NS). CONCLUSIONS: This study suggests that scraping method is simple and useful for isolation of preantral follicles, because this method reduced handling time and recovered enough follicles. The recovered rate of isolated follicles in diameter of 91~130 micrometer was highest in all methods.
