ABSTRACT
<p><b>OBJECTIVE</b>Following the former report, we continue to observe the chronic renal tubular-interstitial injury induced by Radix Aristolochiae Fangchi Extract(RAFE) in rats in order to understand whether RAFE in different doses causes the renal tubular-interstitial injury or not.</p><p><b>METHOD</b>RAFE at the dose of 25.0 mg x kg(-1) x d(-1), 120.0 mg kg(-1) x d(-1) and 200.0 mg x kg(-1) x d(-1) and aristolochic acid (AA, 10.0 mg x kg(-1) d(-1)) was interruptedly administrated by gastric tube for 22 w and 4 w durg withdrawal. Blood, urine and kidney were taken out respectively in 17 w, 22 w and 26 w to measure the indexes of renal function. The morphology of kidney was observed, and Masson staining of kidney were made respectively to compare RAFE groups with AA group.</p><p><b>RESULT</b>Pathological changes of renal tissue forms were as follows All RAFE groups and AA group could develop the pathological process of renal tubular injury-chronic renal interstitial fibrosis. The pathologic changes of RAFE were similar with AA.</p><p><b>CONCLUSION</b>RAFE at all doses administrated interruptedly by gastric tube above 13 w caused chronic renal tubulo-interstitium fibrosis. The renal injury in functions and tissue forms in rats were similar with AA closely. The results showed that AA was the main toxic composition of RAFE.</p>
