In this study, we investigated the protective effects of Peganum harmala seeds extract (CPH) against chronic ethanol treatment. Hepatotoxicity was induced in male Wistar rats by administrating ethanol 35% (4 g/kg/day) for 6 weeks. CPH was co-administered with ethanol, by intraperitonial (IP) injection, at a dose of 10 mg/kg bw/day. Control rats were injected by saline solution (NaCl 9‰). Chronic ethanol administration intensified lipid peroxidation monitored by an increase of TBARS level in liver. Ethanol treatment caused also a drastic alteration in antioxidant defence system; hepatic superoxide dismutase (SOD), catalase (CAT) and glutathione peroxidase (GPx) activities. A co-administration of CPH during ethanol treatment inhibited lipid peroxidation and improved antioxidants activities. However, treatment with P. harmala extract protects efficiently the hepatic function of alcoholic rats by the considerable decrease of aminotransferase contents in serum of ethanol-treated rats.
在本研究中,我们调查了骆驼蓬种子提取物(CPH)对慢性乙醇处理的保护作用。通过给雄性Wistar大鼠腹腔注射35%乙醇(4克/千克/天),持续6周,诱导肝毒性。CPH以10毫克/千克体重/天的剂量通过腹腔注射与乙醇共同给药。对照大鼠注射生理盐水(0.9%氯化钠)。慢性乙醇给药通过肝脏中硫代巴比妥酸反应物(TBARS)水平的升高加剧了脂质过氧化。乙醇处理还导致抗氧化防御系统发生剧烈变化;肝脏超氧化物歧化酶(SOD)、过氧化氢酶(CAT)和谷胱甘肽过氧化物酶(GPx)活性。在乙醇处理期间共同给予CPH可抑制脂质过氧化并改善抗氧化剂活性。然而,用骆驼蓬提取物治疗可通过显著降低乙醇处理大鼠血清中的转氨酶含量,有效保护酒精性大鼠的肝功能。
