Abstract:
Objective To investigate the mechanism by which taxol induces apoptosis of pancreatic acinar cells during experimental acute pancreatitis in rats. Methods Intrapancreatobiliary duct injection of sodium deoxycholate was carried out to establish acute pancreatitis model in Wistar rats. Taxol was injected intraperitonealy to induce pancreatic acinar cell apoptosis. The expression of apoptosis associated protein Bcl-2,Bax,Fas,FasL and p53 was detected by immunohistochemistry. Results The expression of Bax(2 506?942),Fas(279?150) and p53(180?56) increased,while Bcl-2(79?42) remained unchanged in pancreatic acinar cells during acute pancreatitis,and the expression of FasL could only be detected in infiltrative inflammatory cells. Conclusions During acute pancreatitis,the acinar cell apoptosis induced by taxol is associated with activity regulation of Bax,Fas/FasL system and p53.
