蟾砂胶囊急性与长期毒性研究

目的探讨蟾砂胶囊单次或多次给药后,动物出现的毒性反应及其性质和程度,为临床安全用药提供毒理学依据。方法急性毒性实验采用小鼠灌胃给予蟾砂胶囊浸膏10.8g/kg体重(分2次),观察14d;长期毒性实验采用大鼠连续以蟾砂胶囊19.98g/kg、9.99g/kg、2.00g/kg体重,灌胃给药180d,停药30d,观察其雌雄大鼠体重、食量及粪便等一般临床体征,检测血液学指标、血液生化指标、脏器指数,并对主要器官和组织进行了病理学观察。结果小鼠灌胃最大耐受量为45.8g生药/kg,相当临床用量的92.3倍。长期毒性试验中,中、高剂量组对血液学指标,高剂量组对血液生化学指标、脏器重量绝对值、脏器指数等出现一定的影响,部分指标有显著差异(P<0.01),脏器肉眼观察及病理学检查可见肝脏和肾脏有病理改变。停药恢复30d后,大鼠体重、摄食量、活动、血液学、生化指标检查、脏器重量系数、病理学检查均正常。结论蟾砂胶囊在说明书推荐剂量下服用是安全可靠的。

Study of Acute and Long-term Toxicity of Chansha Capsules

Objective To observe acute toxicity in mice and long-term toxicity in rat of Chansha Capsules.Methods Given the extract of Chansha Capsules 10.8g/kg to the rats for 14 days,and calculated the maximum administration dosage.In the long-term toxicity test,rats were continuously fed with Chansha capsule at 19.98g/kg,9,99g/kg and 2.00g/kg a day for 180 days,and 30 days of stopping treatment,observe the male and female rats weight and appetite and feces,general clinical signs,the indication of hematology and bloo...
