AIM:To study the effects of ulinastatin (UTI) on infection of rats with obstructive jaundice.METHODS: Eighty SD rats were assigned randomly into four groups: Control group (A), UTI group (B), prevent group (C) and pseudoperation group (D), and were sacrificed seven days late. A, B and C groups were operated on, the common bile-duct was ligated. UTI was given intraperitoneally at the dosage of 40 000 IU/kg/d in UTI group at the first day of postoperation and in prevent group at the previous day of preoperation. In the control and pseudoperation groups, 0.9 % NS was given intraperitoneally at the first day of postoperation. When the rats were sacrificed, their blood was taken for blood routine and germ culture A small part of the live was taken for light microscopic examination. RESULTS: The WBC levels of A, B, C and D groups were (19 4±2 4)×10 9 ·L -1 , (14 9±2 3)×10 9 ·L -1 , (11 0±2 7)×10 9 ·L -1 and (9 2±1 8)×10 9 ·L -1 , respectively, which were significantly different ( P 0 01). By light microscopic examination, the degeneration of hepatocytes and neutrophil infiltration in the liver in A, B and C groups was observed. The changes in A group was more obvious than those in the other groups and focal necrosis of hepatocytes and lobules damage were also observed. CONCLUSION: UTI has a significant preventive effects on the infection of rats with obstructive jaundice.
