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.

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.

OBJECTIVES: The purpose of this study was to investigate the differences between potential neuroanatomical sites of action of(1) a typical antipsychotic drug (haloperidol), (2) an atypical antipsychotic drug (clozapine), and (3) three combinations of both haloperidol and serotonergic agents (haloperidol+buspirone, haloperidol+cyproheptadine, haloperidol+fluoxetine) by comparing their effects on c-fos expression in the rat brain. METHODS: Twenty-four Wistar rats of male sex, weighing 300-450 g, were divided into 6 groups according to the type of the agents tested [vehicle (0.14 M acetic acid 1 ml/kg), haloperidol (1.0 mg/kg), clozapine (20 mg/kg), haloperidol+buspirone (1.0 mg/kg+1.0 mg/kg), haloperidol+cyproheptadine (1.0 mg/kg+1.0 mg/kg), haloperidol+fluoxetine (1.0 mg/kg+0.25 mg/kg)]. The brain of variously treated rat was examined 2 hours after subcutaneousely injection in the neck. The brain was removed immediately after perfusion with 4% paraformaldehyde and placed in a fresh fixative of the same solution. After 12-hr fixation, brain sections (30 mum) of the areas including the medial prefrontal cortex, nucleus accumbens, and lateral striatum were stained by Fos immunohistochemistry, and subjected to light microscopic analytical observations. RESULTS: 1) The number of Fos-positive neurons in the medial prefrontal cortex was significantly increased in the clozapine, haloperidol+buspirone, haloperidol+cyproheptadine, and haloperidol+fluoxetine treated groups than in the control group (p<0.05). But, the haloperidol treated group shows no significant difference. 2) The number of Fos-positive neurons in the nucleus accumbens was significantly increased in the haloperidol clozapine, haloperidol+buspirone, haloperidol+cyproheptadine, haloperidol+fluoxetine treated groups than in the control group (p<0.05). 3) The number of Fos-positive neurons in the lateral striatum was significantly increased in the haloperidol, haloperidol+buspirone, haloperidol+cyproheptadine, haloperidol+fluoxetine treated groups than in the control group (p<0.05). But, the clozapine treated group shows no significant difference. CONCLUSION: These results suggest that differential expression of c-fos in rat brain induced by haloperidol, clozapine, and haloperidol combined serotonergic agents is associated with their clinical and pharmacological differences.
