  • To investigate the acupuncturing function of $ST_{36}$(足三里) on the gastric activity, four different treatment methods such as intact, local anesthesia, ligation and nerve dissection were implemented. Followings are the results from the present study. 1. When a simple acupuncture with intact, the stomach motility and frequency were increased without significance compared with control. 2. Under local anesthesia on femoral region, the stomach motility and frequency showed no such changes compared with control. 3. With ligation of femoral region, the stomach motility and frequency were decreased significantly compared with control. 4. When the siatic nerve was dissected, the stomach motility and frequency showed no such changes compared with control. Overall, the effect of acupuncture on the $ST_{36}$(足三里) was very closely related with the condition of surrounding area. It is assumed that further studies should be done for the investigation of mechanism behind the acupuncturing function in conjunction with the nervous system.

  • Inulin space was measured in the normal control rabbits and abdominal vena cava partially ligated (to about 1/2 of normal lumen) rabbits. Eleven rabbits served as the control and 12 rabbits after 7 to 10 days of abdominal vena cava ligation were used. Inulin space in the normal rabbits was $376{\pm}102.70\;ml\;(Mean{\pm}S.D.)\;or\;18.0{\pm}5.21%$ body weight. After 7 to 10 days of abdominal vena cava partial ligation inulin space decreased and the values were; $253{\pm}145.79\;ml\;or\;14.4{\pm}8.55%$ body weight.

  • In this study, an environment-friendly synthetic strategy to process zinc oxide nanocrystals is reported. The biosynthesis method used in this study is simple and cost-effective, with reduced solvent waste via the use of fruit peel extract as a natural ligation agent. The formation of ZnO nanocrystals using a rambutan peel extract was observed in this study. Rambutan peels has the ability to ligate zinc ions as a natural ligation agent, resulting in ZnO nanochain formation due to the presence of an extended polyphenolic system over the whole incubation period. Via transmission electron microscopy, successful formation of zinc oxide nanochains was confirmed. TEM observation revealed that the bioinspired ZnO nanocrystals were spherical and/or hexagonal particles with sizes between 50 and 100 nm.

  • Possible mechanism of decreased catechol-O-methyltransferase (COMT) activity in cholestatic rat liver was studied. Hepatic and serum COMT activities were determined from the experimental rats with common bile duct ligation (CBDL). The Michaelis-Menten constants in this hepatic enzyme were also measured. The activities of cytosolic, mitochondrial and mircosomal COMT as well as their Vmax values were found to be decreased significantly in CBDL plus taurocholic acid (TCA) injected group than in the control group, such as CBDL alone groups. However, their Km values in the experimental groups did not vary. Serum COMT activity increased slightly in the CBDL plus TCA injected group than in the control group. The above results suggest that TCA represses biosynthesis of the COMT in the liver. The elevated activity of the serum COMT is believed to be caused by the increment of membrane permeability of hepatocytes upon TCA mediated liver cell necrosis.

  • Possible mechanisms of increased serum aryl sulfotransferase (AST) isozyme activities in cholestatic rats were studied. Serum AST-I, II and -III, IV isozymes activities were determined from the experimental rats with common bile duct ligation (CBDL) or choledocho-caval shunt (CCS). The activities of serum AST-I, II and -III, IV isozymes were found to be increased significantly in both the CCS plus taurocholic acid (TCA) injected group, and the CBDL plus TCA group than those in each control group, such as CCS or CBDL alone groups. The above results suggest that the elevated serum AST most likely due to increased hepatocyte membrane permeability caused by TCA mediated liver cell necrosis.

  • An aberrant right subclavian artery is a rare congenital anomaly that usually does not produce symptoms. Symptomatic patients require surgical intervention. Ligation of the aberrant artery through a left thoracotomy has been advocated as the operation of choice. If development of vertebrobasilar insufficiency is anticipated, division and ligation of he aberrant artery and its anastomosis to the right common carotid artery or aortic arch are performed at a second operation. Experience with successful surgical treatment of a patient with an aberrant subclavian artery is described. A right thoracotomy incision was utilized for division of the subclavian artery and for reestablishment of arterial continuity with Dacron graft. Postoperative arteriography demonstrated a good reconstruction and normal blood flow was established to the right upper extremity.
