摘要: 目的:用ICR 小鼠研究重组葡激酶(r - SAK) 的致畸作用。方法: ICR 小鼠于妊娠第6 - 15d 静脉注射r - SAK,剂量为100mg/ kg. bw、31. 6mg/ kg. bw、10mg/ kg. bw , 同时设立阴性对照组和阳性对照组,于孕第18d 处死动物,进行各项检查。结果:各剂量组孕鼠增重、活胎率、胎鼠体重、身长及尾长与阴性对照组比较,差异皆无显著性( P > 0. 05) ; 各剂量组胎鼠外观、内脏和骨骼均无畸形发现。结论:在本实验条件下,r - SAK对ICR 小鼠无致畸作用。

Abstract: Purpose : To research the teratogenic effect of recombinant staphylokinase ( r - SAK) on ICR mice. Methods : The animals were divided into negative and positive cont rol and three experiment groups which were int ravenously given by r - SAKf rom Day 6 to Day 15 of gestation in dosages of 100mg/ kg. bw , 31. 6mg/ kg. bw and 10mg/ kg. bw , respectively. The body growth gains of gestation mice , the numbers , body weight , length and tail length in living fetus and some indicators of embryonic formation were measured. Results : There were no significant differences as compared with negative cont rol groups. Besides , the deformity of the appearances , internal organs and bone in fetal mice was not found. Conclusion : The result s indicated that r - SAK had no teratogenic effect on ICR mice in this experiment .

Key words: recombinant staphylokinase, teratogenicity
