Effect of Reptilase on Bleeding Time and Blood Coagulate Function in Rabbits / 中国药房

ABSTRACT

OBJECTIVE: To evaluate the dose-effect relationship of reptilase in hemostasis. METHODS: The effects of different doses of reptilase on bleeding time (BT), Blood coagulation and hemorheology in New Zealand rabbits were examined. RESULTS: Reptilase showed a significant hemostatic effect at the dosages of 0.023, 0.07, 0.21 and 0.63KU?kg-1, respectively, with the hemostatic effect lower in 0.63KU?kg-1 group than in 0.21KU?kg-1 group; and at the 4 different dosages, reptilase showed no significant effect on fibrinolysis system. At a dosage of 1.90 or 5.71KU?kg-1, reptilase showed a significant anticoagulation efficacy and enhanced fibrinolysis function. There was no significance in hemorheology among groups. CONCLUSION: At a dosage range of 0.21～0.63KU?kg-1, reptilase has an optimal hemostatic effect in New Zealand rabbits.
