Abstract

In recent years, there has been an escalation in alcohol abuse and inevitably, alcohol related disorders are becoming an increasingly important cause of morbidity and mortality. Alcohol is known to induce a dose dependent increase in lipid peroxidation. Alcohol related disabilities are more pronounced when taken along with diet rich in polyunsaturated fatty acid (PUFA). The present work aims at analysing the protective role of ferulic acid (FA), a naturally occurring nutritional component on alcohol and PUFA induced oxidative stress. Two different doses of ferulic acid, 20 mg/kg body weight and 40 mg /kg body weight were used for the study. The results showed that the levels of oxidative markers; thiobarbituric acid reactive substances (TBARS), hydroperoxides (HP) and levels of copper (Cu) and ferritin were increased significantly in plasma of alcohol, thermally oxidised PUFA (DeltaPUFA) and alcohol + DeltaPUFA groups, which were decreased significantly on treatment with both the doses of ferulic acid. The activities of enzymic antioxidants viz. superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx) and non enzymic antioxidants like vitamin C, vitamin E, and reduced glutathione (GSH) and the levels of zinc (Zn) were significantly decreased in alcohol, DeltaPUFA and alcohol + DeltaPUFA groups which were improved significantly on treatment with both the doses of FA. The reduction in oxidative stress was more significant in 20 mg/kg body weight treatment groups compared to 40 mg/kg body weight. Thus from the results obtained, we conclude that FA effectively protects the system against alcohol and PUFA induced oxidative stress.

摘要

近年来,酒精滥用情况不断升级,与之相关的疾病不可避免地成为发病率和死亡率日益重要的原因。已知酒精会导致脂质过氧化呈剂量依赖性增加。当与富含多不饱和脂肪酸(PUFA)的饮食一起摄入时,与酒精相关的残疾会更加明显。本研究旨在分析阿魏酸(FA)这种天然营养成分对酒精和PUFA诱导的氧化应激的保护作用。研究使用了两种不同剂量的阿魏酸,即20毫克/千克体重和40毫克/千克体重。结果表明,在酒精组、热氧化PUFA(DeltaPUFA)组和酒精 + DeltaPUFA组的血浆中,氧化标志物硫代巴比妥酸反应性物质(TBARS)、氢过氧化物(HP)以及铜(Cu)和铁蛋白的水平显著升高,而在使用两种剂量的阿魏酸治疗后,这些水平显著降低。酶促抗氧化剂超氧化物歧化酶(SOD)、过氧化氢酶(CAT)、谷胱甘肽过氧化物酶(GPx)以及非酶促抗氧化剂如维生素C、维生素E和还原型谷胱甘肽(GSH)的活性,以及锌(Zn)的水平在酒精组、DeltaPUFA组和酒精 + DeltaPUFA组中显著降低,而在使用两种剂量的FA治疗后显著改善。与40毫克/千克体重治疗组相比,20毫克/千克体重治疗组的氧化应激降低更为显著。因此,根据所得结果,我们得出结论,FA能有效保护系统免受酒精和PUFA诱导的氧化应激。
