摘要:

本文主要观察酢浆草乙醇提取物对小鼠出血时间(BT)、凝血时间(CT)和急性毒性作用。首先取40只小鼠, 随机均分为正常对照组、云南白药组、酢浆草乙醇提取物低剂量组和高剂量组。给药组以酢浆草乙醇提取物低剂量(0.6 g/kg)、高剂量(1.2 g/kg)灌胃, 应用玻片法、剪尾法测定小鼠的凝血时间(CT)、止血时间(BT); 再取50只小鼠, 采用半数致死量法, 对小鼠进行灌胃给药, 观察小鼠生理状态、中毒反应及死亡, 于试验第14天剖检观察其脏器有无异常情况。结果在凝血止血试验中, 我们发现各组间无统计学差异(P > 0.05), 但具有明显的剂量反应关系, 且BT时间和CT时间明显低于阴性对照组, 和云南白药对照组相当。在急性毒性试验中, 酢浆草乙醇提取物半数致死量为6.0291 g/kg, 95%可信区间为5.3065–6.7829 mg/kg。

Abstract:

In the present study, we aimed to observe the effects of ethanol extract of Oxalis corniculata L. on bleeding time (BT) and coagulation time (CT) and determine its acute toxicity in mice. Firstly, the ethanol extract of O. corniculata was administered to 40 mice, which were randomly divided into the normal control group, Yunnan Baiyao control group, low-dose group, and high-dose group. The low-dose (0.6 g/kg) and high-dose (1.2 g/kg) groups received ethanol extract of O. corniculata by gavage, and the BT and CT of the mice were measured by the slide method and tail clipping method, respectively. Secondly, the median lethal dose method was used with 50 mice to observe the physiological state, poisoning reaction, and death of the mice after intragastric administration. Finally, on the 14th day of the experiment, a necropsy was performed to observe any abnormality of the organs. In conclusion, in the coagulation and hemostasis tests, there were no statistical differences between the groups (P > 0.05), while there was a significant dose-response relationship, and the BT and CT were significantly shorter than those of the negative control group, which were comparable to the Yunnan Baiyao control group. Moreover, in the acute toxicity test, the median lethal dose of ethanol extract of O. corniculata was 6.0291 g/kg, with a 95% confidence interval of 5.3065–6.7829 mg/kg.
