Exposure to pesticides can pose a greater threat to multiple organs of nontarget animals. Cartap is a thiocarbamate pesticide, broadly used in agricultural fields. The assessment of neurotoxicity of cartap has not been properly studied in the mammalian systems. The present investigation unveils the toxic effects of cartap in the brain of Wistar rats its amelioration by using aqueous extract of leaves. We have used 4 groups of animals comprising six in each: Group 1- control, Group 2- control with , Group 3- cartap, Group 4- cartap with treated After 15 days of treatment, biochemical investigations were conducted. Wistar rats orally exposed to sublethal doses of cartap, showed significant variations in the levels of prooxidants i.e. MDA and GSH (an oxidative stress marker) and enzymatic antioxidants i.e. SOD, CAT, GST, GPx. The decreased levels of CAT, SOD, GST and increased levels of GPx were detected in the experimental rats treated with cartap. The significant alterations were recorded with the declined activities of LDH and AChE, considered as the biomarker of energy metabolism and altered cholinergic function, respectively. However, the pre-administration of aqueous extract of leaves was found to markedly ameliorate the toxic effects of cartap by shielding the levels of aforesaid oxidative markers near to the control. The ameliorative impact of , might be due to the presence of several antioxidant molecules in it which were able to counter the oxidative stress generated by cartap stress. These results suggested that could be utilized as a possible supplement with the relevant therapeutics in the suitable management of cartap toxicity in association.
接触农药会对非靶标动物的多个器官构成更大威胁。杀螟丹是一种硫代氨基甲酸盐类农药,广泛应用于农业领域。在哺乳动物系统中,尚未对杀螟丹的神经毒性进行充分研究。本研究揭示了杀螟丹对Wistar大鼠大脑的毒性作用以及叶水提取物对其的改善作用。我们使用了4组动物,每组6只:第1组为对照组,第2组为对照组加[此处原文缺失具体添加物],第3组为杀螟丹组,第4组为杀螟丹加[此处原文缺失具体添加物]处理组。处理15天后,进行了生化研究。经口暴露于亚致死剂量杀螟丹的Wistar大鼠,其促氧化剂(即丙二醛和谷胱甘肽,一种氧化应激标志物)以及酶促抗氧化剂(即超氧化物歧化酶、过氧化氢酶、谷胱甘肽S-转移酶、谷胱甘肽过氧化物酶)的水平出现了显著变化。在用杀螟丹处理的实验大鼠中,检测到过氧化氢酶、超氧化物歧化酶、谷胱甘肽S-转移酶水平降低,谷胱甘肽过氧化物酶水平升高。乳酸脱氢酶和乙酰胆碱酯酶的活性分别出现显著改变,它们分别被视为能量代谢和胆碱能功能改变的生物标志物。然而,发现预先给予叶水提取物可通过将上述氧化标志物的水平维持在接近对照组的水平,从而显著改善杀螟丹的毒性作用。[此处原文缺失具体植物名称]的改善作用可能归因于其中存在多种抗氧化分子,这些分子能够对抗杀螟丹应激产生的氧化应激。这些结果表明,[此处原文缺失具体植物名称]可作为一种可能的补充剂,与相关治疗方法联合用于杀螟丹毒性的适当管理。
