Abstract:
OBJECTIVE:To study the pharmacokinetics of recombinant staphylokinase(r-SAK)in a thrombosis model of femoral artery in rabbits.METHODS:Large glass plates were used for modified agar-well diffusion assay to measure r-SAK concentration in plasma of rabbits which had been administered different doses drug by different means respective?ly.RERULTS:The pharmacokinetics of r-SAK infusion in thrombosis model of the femoral artery in rabbits fits two-com?partment model,the plasma levels and the diameter of lytic circles showed a good linear correlation under the scope of20~2500IU/ml(r=0.9960),and the averaged recovery rate was(96.05?9.20)%.The peak concentrations of low,medial and high dose drop group and single iv group are(2.28?1.06),(3.54?0.32),(6.12?1.61)and(5.16?1.02)?g/ml.CONCLUSION:The biological assays is a simple,reliable method to determine the plasma level.
