-
摘要: [摘要]目的 对地衣抗癌活性部位AMH-T进行常规毒理学试验研究,了解其毒作用的性质和强度,为抗癌药物的开发提供安全性依据.方法 急性毒性试验、小鼠骨髓微核试验、小鼠精子畸形试验、Ames试验.结果 雄性小鼠经皮下注射给药的LD50为147 mg/kg,雌性小鼠的LD50为171 mg/kg.小鼠骨髓微核试验、小鼠精子畸形试验和Ames试验在试验剂量下未见阳性结果.结论 AMH-T皮下注射给药具有较强的急性毒性和肝毒性,实验剂量范围内未见遗传毒性.Abstract: [Abstract]Objective To provide safety reference for the development of anti-cancer drugs by evaluating thetoxicological safety of the anticancer bioactive fraction AMH-T of lichen through the understanding of its poisonous nature and the intensity. Methods Acute toxicity test, bone marrow micronucleus test in mice,sperm malformation test in rats, Ames test and short-term repeat drug test in mice were conducted. Results Male mice were injected LD50 of 147 mg/kg and female mice 171 mg/kg. Conclusion Injection of AMH-T has acute toxicity and liver toxicity,but has no genetic toxicity.
