The study was designed to clarify the hapato-nephroprotective effects of purslane ethanolic extract (PEE) against cadmium toxicity. Cadmium (Cd) is a toxic heavy metal. Cd occurs as environmental and food/ feed contamination causing public and animals health hazards. Liver and kidney are the main target organs for acute and chronic cadmium toxicity. Portulaca is rich in several vitamins, minerals, antioxidant components, and omega-3 fatty acids mainly α-linolenic acid and eicosapentaenoic acid. Results showed significant elevation of the liver and kidney functions, lipid profile and lipid peroxidation. In contrast to the antioxidants enzymatic were greatly decreased. The hepatic and renal tissues showed severe degeneration and necrosis accompanied by severe congestion and multifocal hemorrhages in Cd intoxicated rats. All parameters and tissues showed no changes in rates-treated with both Cd and purslane extract as compared with the control rats. The administration of PEE provided a significantly protection against Cd-induced hepato-nephrotoxicity.
本研究旨在阐明马齿苋乙醇提取物(PEE)对镉毒性的肝肾保护作用。镉(Cd)是一种有毒重金属。镉作为环境污染物以及食品/饲料污染物存在,对公众和动物健康构成危害。肝脏和肾脏是急性和慢性镉中毒的主要靶器官。马齿苋富含多种维生素、矿物质、抗氧化成分以及ω-3脂肪酸,主要是α-亚麻酸和二十碳五烯酸。结果显示,镉中毒大鼠的肝功能、肾功能、血脂谱和脂质过氧化显著升高。与之相反,抗氧化酶活性大幅降低。镉中毒大鼠的肝组织和肾组织出现严重变性和坏死,并伴有严重淤血和多灶性出血。与对照大鼠相比,同时给予镉和马齿苋提取物处理的大鼠的所有参数和组织均未出现变化。给予马齿苋乙醇提取物可显著保护大鼠免受镉诱导的肝肾毒性。
