Experimental Study on the Combined Hyperbaric Oxygen and Ulinastatin of Acute Necrotizing Pancreatitis / 中国普外基础与临床杂志

ABSTRACT

Objective To investigate therapeutic effect and mechanism of hyperbaric oxygen and ulinastatin respectively or combinatively used to treat acute necrotizing pancreatitis (ANP). Methods One hundred and twenty SD rats were divided into 6 groups randomly group of normal control, group receiving sham operation, group of untreated acute necrotizing pancreatitis (ANP group), group of acute necrotizing pancreatitis treated with hyperbaric oxygen (HBO group), group of acute necrotizing pancreatitis treated with ulinastatin (ULT group), and group of acute necrotizing pancreatitis treated with combined hyperbaric oxygen and ulinastatin (HBO+ULT group). The rat model of acute necrotizing pancreatitis was established according to Aho HJ et al. Concentrations of amylase, TNF?, TXB-2 and 6-keto-PGF- 1? in blood were measured through ELISA or radioimmunoassay. Changes of pancreatic histopathology were investigated. SPSS 10.0 was used in statistical analysis. Results The concentrations of amylase, TNF?, TXB-2 in the ANP-treated groups were significantly lower than those of ANP group (P
