The suture techniques to anastomose successfully small vassels of 1mm in diameter were continuous suture and interrupted suture, and patency rate of them has been estabilished by orthopaedic surgeon. In 1962, Chase and Schwarz reported better results with interrupted suture than with a continuous suture, Firsching reported less time using with continuous suture than with interrupted suture, but no difference in flow rate, in 1984 Lilly reported that interrupted suture does no result in stenosis of venous end to end anastomoses by continuous suturing technique, Mao reported that there was no statically significant difference between two suture methods in patency rate. The authors have experimentally studied the patency rate and histopathological findings of two suture techniques in the 20 Newzealand white rabbit at the department of Orthopaedic Surgery, Hanyang University Hospital and can be obtained the following results. l. In arterial patency, the interrupted suture and continuous suture were 100% in rate and patency rate in veins were 95% in interrupted suture and 75% in continuous suture. 2. Subintimal hyperplasia occured earlier in arteries than in veins and it may be due to the medial component of vessel. 3. In anastomoses of small vessel the accurate apposition of cut vessels edges decreased the thrombi formation of vessel.

Glutathione has a key role in several detoxification reactions and in the protection against injury caused by reactive oxygens. Pregnancy-induced hypertension(PIH) is associated with endothelial cell dysfunction. Such dysfunction could be caused by oxidative stress. There is evidence of increased activity of free radicals in PIH, but little is known about the part played by changes in specific antioxidants. In this study, the changes of glutathione levels were investigated in blood of patients with PIH, and cord blood of these patients was also investigated. The glutathione levels in cord blood of neonates from hypertensive pregnant women were significantly higher than in cord blood from normotensive pregnant women. The changes of gamma-glutamuylcysteine synthetase and of glutathione s-transferase in placenta were not significant, but gamma-glutamyl transpeptidase activity increased significantly in placenta of hypertensive pregnant women. These results suggest that the increased glutathione in cord blood of patients with PIH may be due to increased glutathione interorgan transport resulting from incerased activity of the placenta gamma-glutamyl transpeptidase.

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.
