Objective To investigate the effect of Ruigan (L-omithine-L-aspartate) on liver function of perio-perative treatment. Methods 58 patients with obstructive jaundice and having been done operation were randomly di-vided into two groups:ruigan group (cured group,32 cases) and routine hugan group (control group,26 cases). The levels of liver function and endotoxin were detected when being in hospital, before operation and after operation re-spectively. Results Treatment with ruigan could improve the liver function in perioperation, which has significant difference when compared to the control group (P < 0.05).. Ruigan could reduce the level of endotoxin before and af-ter operation (P < 0.05) and improve endotoxaemia in obstructive jaundice. Conclusion Ruigan would improve the liver function and the endotoxaemia in the perioperative obstructive jaundice.

Objective To investigate the effect of ultrasound-guided percutaneous tube drainage in early acute pancreatitis of closed abdominal injury. Methods The clinical data about fifteen ca.ses of acute pancreatitis of closed abdominal injury in our hospital were reviewed retrospectively. Results By ultrasound-guided percutaneous tube drainage, 11 cases were cured, 2 cases were drainaged by open operation with the complication of pancreatic pseudocyst, 2 eases were transfered to superior hospital with state of an illness sharpened. Conclusion Ultrasoundguided percutaneous tube drainage was effective treatment in early acute pancreatitis of dosed abdominal injury,and avoided open operation.
