The role of apoptosis in the pathogenesis of experimental acute pancreatitis

Objective To explore the role of apoptosis in the pathogenesis of acute pancreatitis(AP)and to (investigate) the effect of ligustrazin(LGT) on the apoptosis in acute pancreatitis .Methods Experimental animals were divided into three groups randomly: (1) AP group, (2) comparison group,and (3) therapy group. Pathologic score and TUNEL method were used to detect the pathologic mophology of pancreatic tissue and the pancreatic cell apoptosis index in the 3 groups. Results In the early stage of AP,the majority of cells are apototic and the degree of AP is slight.In the late stage of AP,the majority of cells show necrosis,and the degree of AP is severe.The (induction) of cell apoptosis can lessen the pathologic state of AP. Conclusions The degree of pathologic changes in AP can be lessened by the induction of cell apoptosis,but there is a definte time limit.
