OBJECTIVE: To elucidate the location of leptin and receptors of ovary specimens obtained from patients undergoing hysterectomy by immunohistochemical staining and to determine the effect of leptin on the steroidogenesis of cultured granulosa cells. METHOD: In the culturing process of the granulosa cells, FSH (1 IU/ml)and leptin (50 ng/ml), IGF-I (50 ng/ml) was administered to each study group (Group I: FSH; Group II: FSH, leptin; Group III: FSH, IGF-I, leptin), and the levels of estradiol, progesterone, androstenedione in the culture media was measured by radioimmunoassay. Statistical analysis was conducted by one-way ANOVA with Scheffe test. RESULTS: The results showed that leptin and leptin receptors were both found to be strongly stained in granulosa and theca cells, and also in some interstitial cells. Leptin receptors were also observed in cultured granulosa cells. While there was no statistically significant difference in the androstnedione concentrations between the groups, estradiol concentrations was significantly decreased in Group IV (2202.0+/-151.14 pg/ml) compared to Group III (2859.0+/-122.6 pg/ml), and progesterone concentrations were also significantly decreased in Group II(4696.3+/-190.6 ng/ml) and Group IV (4517+/-206.78 ng/ml) compared to Group III(5546.0+/-179.5 ng/ml). CONCLUSTION: The study result of this study suggest that leptin is directly involved in the regulation of ovarian functions, in particular steroidogenesis.

The UGI studies had been performed to 238 patients below the age of 15 years during the period from Jan. 1979to Jul. 1983 in SCH hospital. The results are as follows; 1. Among 238 cases, 48 cases revealed peptic ulcers ofstomach or duodenum (20.2%). The ulcer was in 31/37 cases of male patients(22.6%), and in 17/101 cases of female(16.8). Below the age of 5 years, ulcer was noted in 9 cases among 61 cases (14.8%), whereas above 5 years, in 39cases among 177 patients (22.0%). 2. In the age group below 5 years, mostly the objective symptoms were discovered(8/9), but above 5 years, complained of subjective symtoms (30/39). 3. The predominant site of peptic ulcer wasgastric antrum in the age group below 5 years (7/9), whereas duodenal bulb above 5 years(33/43). 4. Gastric antrumor duodenal bulb deformity was revealed in 13 cases and most of them were in the age group above 5 years. 5. Alllesion so peptic ulcers in this study were benign in nature. 6. In follow up study after 1 or 2 months, ulcer wasdecreased in size strikingly(9/11).

There have been many reports to date regarding the role of GnRH as a local regulatory factor of ovarian function as studies of human and rat ovaries revealed GnRH and its receptor. In recent studies it has been shown that GnRH directly causes apoptosis in the granulosa cells of the rat ovary, and such results leads to the suggestion that the use of GnRH agonist for more stable long term ovarian hyperstimulation in human IVF-ET programs causes granulosa cell apoptosis which may lead to follicular atresia. Therefore this study attempts to determine if granulosa-luteal cell apoptosis occurs in patients during IVF-ET programs in which GnRH agonist is employed for ovarian hyperstimulation. The quality of oocyte-cumulus complexes obtained during ovum pickup procedures were assessed morphologically and then the fertilization rate and developmental rate was determined. Apoptotic cells among the granulosa-luteal cells obtained during the same procedure were observed after staining with Hematoxylin-rosin. The fragmentation degree of DNA extracted from granulosa-luteal cells was determined and comparatively analyzed. There was no difference in the average age of the patients, the number of oocytes retrieved, and fertilization and developmental rates between the FSH/hMG group and GnRH-long group. There was also no difference in the apoptosis rate and pyknosis rate in the granulosa-luteal cells between the two groups. However, when the oocyte-cumulus complexes were morphoogically divided into the healthy group and atretic group without regard for the method of hyperstimulation, the results showed that the number of oocytes obtained averaged 11.09+/-8.75 and 10.33+/-4.53 per cycle, respectively, showing no significant difference, but the fertilization rate (77.05%, 56.99%, respectively, p<0.01) and developmental ,ate (65.96%, 41.51%, respectively, p<0.01) was significantly increased in the healthy group when compared to the atretic group. The degree of apoptosis in the granulosa-luteal cells showed that in the healthy group it was 2.25% which was not significantly different from the atretic group (2.77%), but the pyknosis rate in the atretic group (27.81%) was significantly higher compared to the healthy group (11.35%, p<0.01). The quantity of DNA fragmentation in the FSH/hMG group was 32.22%, while in the GnRH-long group it was 34.27%, showing no significant difference. On the other hand the degree of DNA fragmentation was 39.05% and 11.83% in the healthy group and atretic group, respectively, showing significantly higher increase in the atretic group (p<0.01). The above results suggest that death of granulosa-luteal cells according to the state of the oocyte-cumulus complex is more related to pyknosis rather than apoptosis. Also, the GnRH agonist used in ovarian hyperstimulation does not seem to directly affect the apoptosis of retrieved oocytes and granulosa-luteal cells, and which is thought to be due to the suppression of the apoptogenic effect of GnRH agonist as a result of the high doses of FSH administered.
