大黄素诱导细胞凋亡对不同类型急性胰腺炎腺泡死亡方式的影响

Objective To investigate the effect of Chinese medicine emodin on death patterns of pancreaticacinar cells in different types of aute pancreatitis and explore its possible mechanism. Methods Rat acute edematous pancreatitis models and acute necrotic pancreatitis models were estab-lished and treated with emodin. Alternations of apoptosis, NF-κB mRNA, Pax mRNA and TNF-α mRNA expression in pancreatic tissue were studied with in situ TUNEL and RT-PCR. Results Nega-tive correlation was found between apoptosis and the severity of pancreatic damage. Following the treatment with emodin, more apoptosis than necrosis was observed in all treaded groups of acute pan-creatitis and the severity of pancreatic histological pathologic damage was dramatically improved. Local expression of NF-κB mRNA and Bax mRNA increased. Conclusion Pancreas aeinar death patterns of apoptosis are induced by emodin. Emodin might regulate the acinar cell death patterns by changing the activation of NF-κB and the expression of bax to lessen the severity.
