Abstract:
Objective To explore the regularity of heat shock protein 70(HSP70)expression and its function in renal ischemia/reperfusion injury(IRI),and to reveal whether traditional Chinese medicine, Xuebijing injection(血必净注射液),induces HSP70 synthesis and has a protective effect on IRI.Methods One hundred and eight female Sprague-Dawley(SD)rats,(200?20)g in weight,were used in this experiment,and randomly divided into three groups(each n=36):control(A),model(B)and treatment group(C).The I/R model was established by clamping renal pedicles on both sides for 45 minutes to cause ischemia and then reperfusion was made.In group A,a similar model procedure was performed,but without ischemia.At 5-10 minutes before the IRI was performed,5 ml/kg of normal saline and 5 ml/kg of Xuebijing injection was injected through the femoral vein in group B and C respectively.In B and C groups,according to the durations of reperfusion for 0,6,12,24,36 and 48 hours,the rats were subdivided into six subgroups (each n=6).At the end of each time point,blood and renal tissue were collected to measure blood creatinine (SCr)and urea nitrogen(BUN),and Western blotting method was used to examine the expression of HSP70. In another kidney,renal tissue was obtained for hematoxylin and eosin(HE)staining pathological and immunohistochemical examinations.Results In B and C groups,the SCr and BUN levels at 6 hours after I/R were significantly higher than those in the A group,and those in the C group were lower than those in the B group(P
