Abstract:
OBJECTIVETo observe the renal function, histology and the levels of interleukin-1beta (IL-1beta), interleukin-6 (IL-6) in rats administered with Aristolochi manshriensis (AM) and Longdan Xiegan decoction (LDXG) containing AM.
METHODDivided SD rats into control, AM and LDXG groups (n = 10 per group) at random and administrated orally for 8 weeks with distilled water, AM (6 g x kg(-1) x d(-1)) and LDXG (17. 5 g x kg(-1) x d(-1), containing AM 6 g x kg(-1) x d(-1)), respectively. Measured renal functional parameters in serum, urine and IL-1beta, IL-6 in renal homogenate, and observe renal histologic lesions at the end of 8 weeks.
RESULTTwo kinds of water abstract induced significantly renal injury in rats, IL-1beta, IL-6 levels in renal homogenate were significantly increased compared with controls, histological section showed inflammatory cell infiltration play important role in renal tubulointerstitium damage. LDXG caused less seriously damage than AM.
CONCLUSIONAM and LDXG in experimental dosage can induce renal injury, inflammatory cell infiltration in renal tubulointerstitium and high levels of IL-1beta, IL-6 presumpt that the nephrotoxicity of AM and LDXG refered to the immune mechanism. LDXG has light nephrotoxicity due to its restraining the inflammatory reaction caused by AM.
