摘要: 目的:观察槲皮素(quercetin, Que) 对环孢素A(cyclosporine A, CsA) 肾毒性的影响。方法:大鼠28只随机分为4 组:正常对照组、Que (40 mg/kg) 组、CsA (40 mg/kg) 模型组、CsA (40 mg/kg) +Que(40 mg/kg) 组。以上各组动物每天给药1 次, 连续给药15 d 。各组大鼠于给药d 10 及d 14 分别置于代谢笼中收集24 h 尿液检测尿蛋白含量和尿N-乙酰-β-D-氨基葡萄糖苷酶(NAG) 活性;于末次给药4 h 后处死大鼠, 测血清BUN、 Cr 和肾组织还原型谷胱甘肽(GSH)、 丙二醛(MDA) 含量及超氧化物歧化酶(SOD)、 谷胱甘肽-S-转移酶(GST)、 谷胱甘肽过氧化物酶(GSH-Px)、 过氧化氢酶(CAT) 活性;肾组织10% 甲醛溶液固定, 石蜡包埋,HE 染色, 光镜观察其形态学变化。结果:Que 对CsA 所致的尿蛋白、尿NAG、 BUN、 Cr、 肾组织MDA 含量的升高均有显著降低作用, 并明显增加肾组织GSH 含量及GST、 SOD、 GSHPx、CAT 活性, 对CsA 引起的肾小管病理性损伤也有较好的保护作用。结论:Que 对CsA 所致的肾脏毒性具有明显的保护作用。

Abstract: AIM:To investigate the protective effects of quercetin on nephrotoxicity induced by cyclosporine A (CsA) in rats.METHODS:Male Sprague-Dawley (SD) rats were divided into four groups of seven rats each. Control group, quercetin (40 mg/kg) group, CsA (40mg/kg) group, CsA (40 mg/kg) plus quercetin (40 mg/kg) group. The all groups were administered once day respectively for 15 days. Twenty-four hour urines were collected at the 10th and 14th day respectively after administration to measure the content of urinary protein and urinary Nacetyl-β-D-glucosaminidase (NAG). The animals in all groups were sacrificed 4 h after the last administration. Blood samples were collected to measure serum creatinine (SCr), blood urea nitrogen (BUN). Kidneys were removed rapidly, excised and sectioned for histological analysis. Other kiney tissues were utilized for biochemical analysis.RESULTS: Quercetin prevented urinary protein, SCr, BUN, NAG, and kidneys histological alterations. Quercetin significantly decreased malondialdehyde (MDA) content while significantly increased glutathione (GSH) content and glutathione-S-transferase(GST), superoxide dismutase (SOD), glutathione peroxidase (GSHPx), catalase(CAT) activities of kidneys tissues in the rats treated with CsA.CONCLUSION:Quercetin can effectively attenuate the nephrotoxicity induced by CsA.

Key words: quercetin, cyclosporine A, nephrotoxicity, antioxidation
