Effect of Puerarin on mechanism of endothelinin in biliary pancretitis with renal impairment / 国际外科学杂志

ABSTRACT

Objective To investigate the mechanism of endothelin (ET) in acute biliary pancretitis (ABP)with renal impairment, and examine the improvement of renal function by puerarin. Methods Thirty-two patients of ABP with renal impairment were selected and were randomly divided into group A and group B. Group A were given puerarin post-operatively, while group B were given common manegement postoperatively. Meanwhile, 16 ABP patients without renal impairment were selected as group C, and 16 nonABP patients who had common hepatic or biliary diseases were selected as group D. The levels of plsma ETand creatinine clearance rate(Ccr) of renal function in each group were observed pre-operation and 1 week post operation. Results In pre-operation the ET level in group A, B and C were higher than in group D(P ＜0.001), and the ET level in group A,B was higher than in group C(P＜0.001). Post operation after I week the ET level in group A was lower than in group B(P =0.014), while the Ccr level in group A was higher thanin group B ( P = 0.002). Conclusions The function of endothelin is an important mechanism in biliary pancretitis with renal impairment. Puerarin might reduce the ET level and increase the Ccr level in patients of ABP with renal impairment, improve the renal function of such patients.
