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.

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.

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.
