This study evaluated the ameliorative potential of aqueous extract of Trichosanthes dioica fruit (AQTD) against arsenic-induced toxicity in rat brain. AQTD (50 and 100 mg/kg) was administered orally to male Wistar albino rats for 20 consecutive days before oral administration of sodium arsenite (10 mg/kg) for 8 days. We then evaluated the brain biochemical parameters viz. lipid peroxidation, reduced and oxidized glutathione, glutathione-S-transferase, glutathione peroxidase, glutathione reductase, superoxide dismutase, catalase, and DNA fragmentation. Pretreatment with AQTD significantly and dose dependently modulated all the antioxidative parameters and reduced DNA fragmentation in rat brain intoxicated with arsenic. These findings conclude that T. dioica fruit possesses a remarkable ameliorative effect against arsenic-induced brain toxicity in male albino rats, which is mediated by alleviation of arsenic-induced oxidative stress by multiple mechanisms.
本研究评估了绞股蓝果水提物(AQTD)对大鼠脑砷毒性的改善潜力。雄性 Wistar 白化大鼠连续 20 天口服 AQTD(50 和 100mg/kg),然后连续 8 天口服亚砷酸钠(10mg/kg)。然后,我们评估了脑生化参数,即脂质过氧化、还原型和氧化型谷胱甘肽、谷胱甘肽-S-转移酶、谷胱甘肽过氧化物酶、谷胱甘肽还原酶、超氧化物歧化酶、过氧化氢酶和 DNA 片段化。AQTD 的预处理显著且剂量依赖性地调节了所有抗氧化参数,并减少了砷中毒大鼠大脑中的 DNA 片段化。这些发现表明,绞股蓝果具有显著的改善作用,可以对抗雄性白化大鼠的砷诱导的脑毒性,这是通过多种机制减轻砷诱导的氧化应激介导的。
