Effect of methanolic extract of Rumex hastatus roots (MRR) and its derived fractions, n-hexane (HRR), ethyl acetate (ERR), chloroform (CRR), butanol (BRR), and aqueous extract (ARR), was studied against carbon tetrachloride (CCl4) induced hepato and testicular toxicity in rats. Intraperitoneal dose of 20 percent CCl4 (0.5 ml/kg bw) was administered twice a week for eight weeks to a group of rats. Other groups were given CCl4 and various fractions of R. hastatus roots (200 mg/kg bw). CCl4 treatment depleted glutathione contents and activities of antioxidant enzymes while increased the concentration of lipid peroxides (TBARS) along with corresponding DNA injuries and histopathological damages. Supplementation with various fractions of R. hastatus roots (200 mg/kg body weight) attenuated the toxicity of CCl4 in liver and testis tissues through improvement in the serological, enzymatic, and histological parameters towards the normal. Posttreatment of R. hastatus roots (200 mg/kg body weight) also reversed the alteration in reproductive hormonal secretions and DNA damages in CCl4 treated rats. The results clearly demonstrated that R. hastatus treatment augments the antioxidants defense mechanism and provides the evidence that it may have a therapeutic role in free radical mediated diseases.
研究了酸模(Rumex hastatus)根的甲醇提取物(MRR)及其衍生的正己烷(HRR)、乙酸乙酯(ERR)、氯仿(CRR)、正丁醇(BRR)和水提物(ARR)对大鼠四氯化碳(CCl4)诱导的肝和睾丸毒性的影响。一组大鼠每周两次腹腔注射 20% CCl4(0.5 ml/kg bw),共 8 周。其他组给予 CCl4 和 R. hastatus 根的各种馏分(200 mg/kg bw)。CCl4 处理会耗尽谷胱甘肽含量和抗氧化酶的活性,同时增加脂质过氧化物(TBARS)的浓度,以及相应的 DNA 损伤和组织病理学损伤。用 R. hastatus 根的各种馏分(200 mg/kg 体重)进行补充,可以通过改善血清学、酶学和组织学参数,减轻 CCl4 在肝和睾丸组织中的毒性,使它们恢复正常。用 R. hastatus 根(200 mg/kg 体重)进行治疗后,还可以逆转 CCl4 处理大鼠生殖激素分泌和 DNA 损伤的改变。这些结果清楚地表明,酸模处理增强了抗氧化剂防御机制,并提供了证据表明,它可能在自由基介导的疾病中具有治疗作用。
