The objective of this study was to investigate the propensity of lambda-cyhalothrin (LTC) to induce oxidative stress in blood and brain of male Wistar rats and its possible attenuation by vitamin C. Rats were randomly divided into four groups: group I served as control rats. group II was treated daily with 200mgvit C/(kgbw) administered by intraperitoneal way. Rats of group III have received orally 668ppm LTC. Animals of group IV were treated with LTC and vitamin C. A decrease of some hematologic parameters (RBC, Hb, Ht: p<0.01) and a significant increase of MDA levels (p<0.05) in erythrocytes and brain were observed in LTC group compared to controls. Antioxidant enzyme activities in both tissues were modified in LTC group compared to controls. Administration of vitamin C ameliorated these parameters. Our results indicated the potential effects of LTC to induce oxidative damage in tissues and the ability of vitamin C to attenuate LTC-induced oxidative damage.
本研究旨在探讨 lambda-氯氰菊酯 (LTC) 在雄性 Wistar 大鼠血液和大脑中诱导氧化应激的倾向,以及维生素 C 对其可能的缓解作用。大鼠随机分为四组:第 I 组作为对照组。第 II 组每天通过腹腔注射 200mg/kgbw 的维生素 C 进行治疗。第 III 组大鼠口服 668ppm 的 LTC。第 IV 组动物接受 LTC 和维生素 C 治疗。与对照组相比,LTC 组的一些血液学参数(RBC、Hb、Ht:p<0.01)和红细胞及大脑中 MDA 水平显著升高(p<0.05)。与对照组相比,LTC 组两种组织中的抗氧化酶活性均发生改变。维生素 C 的给药改善了这些参数。我们的结果表明 LTC 具有诱导组织氧化损伤的潜力,以及维生素 C 减轻 LTC 诱导的氧化损伤的能力。
