is potentially toxic to humans and animals. Its seeds are crop contaminant weeds in some localities where liver disease is prevalent. This study assessed the subacute hepatotoxicity of seeds in mice model. Three groups of female Swiss Albino mice (25-28 g, aged 8-10 weeks) received distilled water (control), 400, and 1000 mg/kg extract of seed, respectively. At the end of the study, body weight and liver organ weight were recorded, and tissue and blood samples were collected and analyzed. The results indicated that the extract treated groups, at both doses, showed significant ( ≤ 0.001) decrease in mean body weight gain in the fourth week of the experiment. Besides, the extract treated groups showed significant ( ≤ 0.001) elevation of liver enzyme markers: alanine aminotransferase and aspartate aminotransferase. Also, histopathological examinations of liver tissue showed moderate microvesicular steatosis of hepatocytes and mild inflammation in the 400 mg/kg treated group as well as marked micro- and macrovesicular steatosis, focal area necrosis, and periportal inflammation with mononuclear cell infiltration in the 1000 mg/kg treated group. Thus, these findings show that seeds exhibit hepatotoxicity in mice, characterized by changes in liver tissue architecture and liver enzyme levels.
对人类和动物具有潜在毒性。在一些肝病流行地区,其种子是作物中的有害杂草。本研究评估了[种子名称]种子在小鼠模型中的亚急性肝毒性。三组雌性瑞士白化小鼠(体重25 - 28克,8 - 10周龄)分别接受蒸馏水(对照组)、400毫克/千克和1000毫克/千克的[种子名称]种子提取物。在研究结束时,记录体重和肝脏器官重量,并采集组织和血液样本进行分析。结果表明,两个剂量的提取物处理组在实验第四周平均体重增加均显著降低(P≤0.001)。此外,提取物处理组的肝酶标志物谷丙转氨酶和谷草转氨酶显著升高(P≤0.001)。而且,肝组织的组织病理学检查显示,400毫克/千克处理组肝细胞有中度微泡性脂肪变性和轻度炎症,1000毫克/千克处理组有明显的微泡和大泡性脂肪变性、局灶性坏死以及汇管区炎症伴单核细胞浸润。因此,这些研究结果表明,[种子名称]种子在小鼠中表现出肝毒性,其特征为肝组织结构和肝酶水平的变化。
