The aim of this study was to investigate a potential preventive effect of phycocyanin extract from against ethanol- induced hepatorenal toxicity and cognitive behavior impairment in male Wistar rats. The animals were randomly and equally divided into four groups (six animals each): control group received saline solution, ethanol (EtOH) group was injected intraperitoneally with 1 ml/kg of ethanol solution 38% (w/v), phycocyanin groups were treated with 25 (PC1) or 50 (PC2) mg/kg phycocyanin extract followed by ethanol administration. All treatments were conducted for 14 successive days. Results revealed that ethanol induced oxidative stress in brain, liver, and kidney by increasing lipid peroxidation level and SOD and CAT activities. Serum biochemical perturbations were also observed in EtOH group, which was indicated by a significant elevation in ALT, AST, cholesterol, triglycerides, creatinine, and urea levels. Combined exposure to EtOH with phytocyanin contracted these biochemical alterations. Phycocyanin decreased also EtOH-induced anxiety and ameliorated exploratory behavior assessed by the elevated-plus maze and open field tests respectively.
本研究旨在探讨螺旋藻藻蓝蛋白提取物对雄性 Wistar 大鼠乙醇诱导的肝肾毒性和认知行为损伤的潜在预防作用。动物随机等分为四组(每组 6 只):对照组给予生理盐水,乙醇(EtOH)组腹腔注射 38%(w/v)乙醇溶液 1ml/kg,藻蓝蛋白组分别给予 25(PC1)或 50(PC2)mg/kg 藻蓝蛋白提取物,然后给予乙醇。所有处理均连续进行 14 天。结果表明,乙醇通过增加脂质过氧化水平和 SOD 和 CAT 活性,在脑、肝和肾中诱导氧化应激。EtOH 组还观察到血清生化扰动,表现为 ALT、AST、胆固醇、甘油三酯、肌酐和尿素水平显著升高。同时暴露于乙醇和藻蓝蛋白可减轻这些生化变化。藻蓝蛋白还降低了乙醇诱导的焦虑,并通过高架十字迷宫和旷场试验分别改善了探索行为。
