Abstract:
Objective To investigate the protection effects and possible mechanism of apoptotic effect of compound Xiancao granules on renal ischemia reperfusion injury ( IRI ) in rats. Methods Renal IRI rat model was established by clipping bilateral renal artery.The rats were divided into model control group (n=10), compound Xiancao granules group (n=10) and sham operation group (n=10).All Serum creatinine (Cr) and blood urea nitrogen (BUN) were determined to evaluate kidney function after IRI.Superoxide dismutase (SOD), glutathione peroxidase (GSH-PX) and malondialdehyde (MDA) activity in kidney were measured by colorimetric method. Expression of apoptotic regulatory genes Bcl-2 and Bax in renal tissue were detected by Western blotting.Renal tissue sections were stained by hematoxylin and eosin (HE) and examined under a light microscope. Results SOD and GSH-PX levels of the compound Xiancao granules group (278.1±16.2),(155.96±20.58) U?mg-1 were significantly higher than those of the model control group (196.3±12.1),(109.34±17.81) U?mg-1 (P<0.05). MDA, BUN and Cr (12.49±1.07) nmol?mL-1,(8.9±2.7) mmol?L-1,(149.7±8.5) μmol?L-1 were significantly reduced in the compound Xiancao granules group as compared with those of the model control group (17.32±1.26) nmol?mL-1,(14.6± 3.3) mmol?L-1,(206.1±11.2) μmol?L-1(P<0.05).Bax and Bcl-2 mRNA expression levels of sham operation group were significantly lower, and the Bax and Bcl-2 mRNA expression levels of model control group were significantly enhanced ( Bcl-2:P<0. 05, Bax: P<0. 01 ) . Bax mRNA expression level of compound Xiancao granules group was significantly decreased as compared with that of model control group ( P<0.05) , but Bcl-2 mRNA expression level of compound Xiancao granules group was significantly enhanced as compared with that of model control group (P<0.01). Conclusion These results suggested that compound Xiancao granules has protection effect on renal IRI in rats. The mechanisms may be related to its antioxidant activity and expression of the apoptotic genes such as Bcl-2 and Bax.
