ABSTRACT
Objective:
To study the therapeutic effect of Kangxianling decoction on renal fibrosis induced by 5/6 nephrectomy, and angiotensin converting enzyme-angiotensin Ⅱ-angiotensin Ⅱ 1 receptor (ACE-AngⅡ-AT1R) axis.Method:
Totally 50 SD rats were randomly divided into the following groupscontrol group (n=10), sham-operation group (n=10), 5/6 nephrectomized renal fibrosis model group (n=30). After two weeks, the rats in operation group were divided into the model group, Kangxianling group, and losartan potassium group, n=10 in each group. Rats in losartan potassium group were administered with losartan potassium by gastrogavage, and rats in Kangxianling group were administered with Kangxianling by gastrogavage. Equal volume of saline was administered to rats in the other groups. The rats were put to death after 16 weeks of consecutive medication, and serum creatinine(SCr), blood urea nitrogen(BUN), 24 h urine protein(24 h-Pro) were measured in each group. Hematoxylin-eosin(HE) staining was used to observe the pathological changes of kidney tissues, and the degree of renal fibrosis was observed by Masson staining. The expressions of ACE1 and AT1R were detected by immunohistochemistry. The protein expression levels of ACE1, AngⅡ and AT1R were determined by Western blot.Result:
Compared with control and sham-operation groups, SCr, BUN and 24 h-Pro in model group were significantly increased (PPPPConclusion:
Kangxianling decoction can delay the progress of renal fibrosis in 5/6 nephrectomized rats, which is closely related to the inhibition of ACE-AngⅡ-AT1R axis activation.
