ABSTRACT
OBJECTIVE To investigate the protective effect of total saponins from stems and leaves of Panax ginseng (GSLS) on cisplatin (CDDP)-induced kidney damage in mice and its possible mechanism. METHODS Thirty-two male ICR mice were randomly divided into normal control group, CDDP group, and GSLS(150 and 300)+CDDP groups. GSLS was administered to mice by oral gavage once a day for 7 d. On the 7th day, a single injection of CDDP 20 mg·kg-1 was given 1 h after GSLS 150 and 300 mg·kg-1 before GSLS 150 and 300 mg·kg-1 continued to be given for 3 d. Blood urea nitrogen (BUN) and creatinine (CRE) , catalase (CAT) in renal tissue, reduced glutathione (GSH), tumor necrosis factorα(TNF-α) and interleukin 1β(IL-1β) of cisplatin induced mice were detected after 72 h. HE and PAS staining were used to observe the renal histopathological changes;While TUNEL and Hoechst33258 staining were employed to observe apoptosis in kidney tissues. RESULTS Compared with normal control group, CDDP group had a significant reduction in relative body mass (P<0.05), and the level of GSH and CAT in kidney tissues (P<0.05). The level of CRE, BUN, TNF-α, and IL-1βin serum and renal indexes significantly increased (P<0.05, P<0.01), especially BUN and CRE that respectively doubled and quadrupled. CDDP group developed glomerulus swelling, renal tubular expansion and epithelial cell necrosis. Trans?parent tube type of tube cavity appeared, the nucleus pycnosis disappeared, but renal interstitial edema and inflammatory cell infiltration appeared. There was a large amount of glycogen deposition and high expressions of TUNEL positive cells and Hoechst33258 positive cells. Compared with CDDP group, the levels of BUN and CRE in GSLS treatment group significantly decreased (P<0.05, P<0.01) in serum, glycogen deposition was reducted and apoptosis of renal tubular epithelial cells decreased in kidney tissues (P<0.05). The level of TNF-α, IL-1β(P<0.05) and the degree of renal tissue necrosis were significantly reduced (P<0.05) in CDDP+GSLS 300 group, but there was a significant increase in the level of CAT and GSH (P<0.05). CONCLUSION GSLS can protect against mouse kidney injury induced by cisplatin. The mechanism may be related to oxidation, reduced inflammation reaction and resistance to apoptosis.
