鹿茸水提物减轻顺铂所致的小鼠肾损伤

目的:探讨梅花鹿二杠茸和三岔茸水提物对顺铂(CDDP)所致小鼠肾损伤的影响。方法:采用灌胃给药方式,用顺铂(15 mg/kg)诱导小鼠肾损伤模型,测定小鼠肾脏指数(KI)、血清肌酐(SCr)、血尿素氮(BUN)、肾脏组织中超氧化物歧化酶(SOD)和谷胱甘肽过氧化物酶(GSH-Px)活性及丙二醛(MDA)含量,并对肾脏组织进行HE染色,观察肾脏病理学变化,研究梅花鹿二杠茸和三岔茸的水提物各剂量对小鼠肾损伤的影响。结果:与顺铂组相比,各剂量鹿茸水提物可显著降低CDDP诱导肾损伤小鼠SCr、BUN水平及肾脏MDA含量,提高SOD和GSH-Px的活性(P0.05);明显改善肾组织病理学形态,减轻CDDP对肾小管上皮细胞的损伤程度,且同等浓度下,与三岔茸相比,二杠茸水提物能更好地改善肾功能及减轻病理损伤。结论:鹿茸水提物减轻顺铂引起的小鼠肾损伤,其作用机制可能与鹿茸水提物增强小鼠肾脏组织的抗氧化能力有关。

Protective effect of aqueous extract of velvet antler on cisplatin-induced nephrotoxicity in mice

AIM: To study the protective effect of aqueous extract of 2-branched and 3-branched velvet antler on cisplatin (CDDP)-induced nephrotoxicity in mice. METHODS:The mouse model of renal injury was induced by intragastric administration of CDDP at the dose of 15 mg/kg. After treatment, kidney index (KI), serum creatinine (SCr), blood urea nitrogen (BUN), the activity of superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px), and the content of malondialdehyde (MDA) in the kidney were determined. The renal pathological changes were observed with HE staining. RESULTS: Aqueous extract of velvet antler at the tested dose markedly decreased BUN, SCr and the content of MDA, and elevated the activity of SOD and GSH-Px in the mice pretreated with CDDP (P<0.05). The pathological changes of the renal tissues were improved obviously, and the injury of the epithelial cells of renal tubules was mitigated. The effect of the aqueous extract of 2-branched velvet antler on renal function and cisplatin-induced nephrotoxicity was better than that of 3-branched one at the same concentration. CONCLUSION: The aqueous extract of 2-branched and 3-branched velvet antler has a certain protective effect on cisplatin-induced nephrotoxicity, which may be associated with increasing the anti-oxidative capability of mouse renal tissue.
