Methods:Oxidative stress was induced by oral administration of ethanol(20%w/v) at a dosage of 5 mL/kg bw in rats.After 28 days of treatment,the rats were fasted overnight and sacrificed by cervical dislocation.Brain tissues were assayed for total phospholipid(TP) content and malondialdehyde(MDA).Results:Administration of alcohol significantly caused a reduction in TP content.Treatment with pineapple peel extract significantly increased the TP content. Significant high levels of MDA was observed in alcohol-fed rats,treatment with pineapple peel extract significantly reduced the MDA levels.Conclusions:Results obtained from this study indicates that pineapple peel extract protects against alcohol-induced changes in total phospholipids and lipid peroxidation in brain tissues.展开更多
