摘要
研究了具有强纤溶性纳豆激酶的安全性,通过小鼠尾静脉注射及最大耐受剂量评价其急性毒性。实验结果表明,纳豆激酶小鼠半致死剂量LD50(尾静脉注射)为172.6kU/kg.bw,小鼠最大耐受剂量MTD为400 kU/kg,口服安全性很高。
Nattokinase (NK) has strong fibrinolytic activity, its acute toxicity was tested in this paper. The medium lethal dose (LD50) of the rats was 172. 6kU/kg. bw by injection, and the maximum tolerated dose (MTD) was 400 kU/kg by gastriclly administered.
