Abstract:
Objective To evaluate the effect of naringenin on KIM-1 expression in rats with renal interstitial fibrosis caused by unilateral ureteral obstruction(UUO).Methods 24 SD male rats were randomly divided into Sham group,UUO group and naringe-nin group(Nar group),respectively.Rats in UUO group and Nar group got UUO to establish renal interstitial fibrosis models. Rats in Sham group only free but not ligated and cut ureters.Rats were administered saline and naringenin 25 mg/(kg·d)for 14 days.Then,24 h urine samples were collected before the rats were killed,and KIM-1 in these samples were measured by ELISA. Specimens were obtained from obstructive renal,the pathological change of renal tubule and interstitial were observe by HE and Masson staining.Moreover,the tubulointerstitial damage index was scored and the expression of KIM-1 in renal tissue was examined by immunohistochemical staining.Results Compared with Sham group,the tubulointerstitial damage index of UUO group significantly increased(P <0.05),contents of KIM-1 in urine and renal tissues also significantly increased(P <0.05).Com-pared with UUO group,the tubulointerstitial damage index score of Nar group alleviated(P <0.01),contents of KIM-1 in urine and renal tissues also reduced(P <0.05 ).Correlation analysis showed that there was positive correlation between KIM-1 in urine and renal tissues and TDI(r=0.862,0.866,P <0.01).Conclusion Naringenin can relieve renal interstitial fibrosis and reduce the content of KIM-1.
