Abstract

The present study aimed to evaluate the acute and subacute toxicity profiles of extracts in mice using the methods described in the guidelines of the OECD. In the acute toxicity study, the LD value was greater than 2000 mg/kg. The subacute toxicity study of extracts showed no significant changes in body or organ weights. The administration of extracts to mice at a dose of 200 mg/kg led to an increase in white blood cells, platelets and hemoglobin. Moreover, the aqueous extract of only decreased liver aspartate aminotransferase (ASAT) levels at a dose of 200 mg/kg, and creatinine and urea levels did not show any significant alterations compared to the control group. Our results showed that the extracts of caused a slight increase in alanine aminotransferase (ALAT) and triglycerides. The histological study showed that mice treated with extracts experienced some histopathological changes in the liver, particularly with the methanolic extract, and slight changes in the kidneys and pancreas. Regarding the renal profile, no toxicity was observed. These results provide basic information on the toxicological profile of used in traditional medicine.

摘要

本研究旨在采用 OECD 指南中描述的方法评估 提取物在小鼠中的急性和亚急性毒性特征。在急性毒性研究中,LD 值大于 2000mg/kg。 提取物的亚急性毒性研究显示,体重和器官重量无明显变化。以 200mg/kg 的剂量给予小鼠 提取物后,白细胞、血小板和血红蛋白增加。此外,只有水提物在 200mg/kg 剂量下降低了天冬氨酸转氨酶 (ASAT) 水平,与对照组相比,肌酐和尿素水平没有显示出任何显著变化。我们的结果表明, 提取物引起丙氨酸转氨酶 (ALAT) 和甘油三酯略有增加。组织学研究表明,用 提取物处理的小鼠肝脏出现一些组织病理学变化,特别是在使用甲醇提取物时,肾脏和胰腺也有轻微变化。关于肾脏特征,未观察到毒性。这些结果为传统医学中使用的 毒性概况提供了基本信息。
