Abstract:
Objective To investigate the function of apoptosis in the renal injury by observing change of renal pathology and ultrastructure in the rat with obstructive jaundice(OJ) and if salvia miltiorrhiza(SM) can lighten the renal dysfunction of obstructive jaundice.Methods A total of 100 adult Sprague-Dawley rats were studied.Among them,the 80 models of obstructive jaundice were established by ligating bile duct(BDL),then divided into two groups: the OJ rats administered daily abdomen injections of SM(1.7g per rat) after operation of bile duct ligation(the SM group,n= 40);the OJ rats receiving only the same normal saline(the OJ group,n=40).The other rats with sham operation receiving only normal saline(the control group,n=20).Three groups of rats were sacrificed in groups at postoperation 1,2,3 and 4 week,respectively.Then serum BUN & Cr were tested and renal change of histopathology and ultrastructure were observed;Apoptosis of renal tissue were assayed by TUNEL method.Results With the time of BDL extending,the value of serum BUN & Cr increased;Apoptotic cells increased in renal tissue.After treatment with SM,the injury degree of renal function and histopathologic changes decreased.Conclusion Obstructive jaundice can lead to renal injury.Apoptosis had an important effect on renal function injury in the rat with obstructive jaundice.Salvia miltiorrhiza can ease the degree of renal function injury.
