查询词典 chain reaction

METHODS: The acute pancreatitis model was induced by retrograde injection of 50 g/L sodium taurocholate into the bili-pancreatic duct in SD rats. Forty-eight mas-culinity SD rats were randomly divided into 2 groups: the sodium taurocholate group and the operational control group. The serum amylase level and the histol-ogical pathologic changes of pancreas were measured at different time point in each group. The expression of pancreatic CINC protein and mRNA were determined by immunohistochemistry and semi-quantitative reve-rse transcriptase polymerase chain reaction, respectively.
