摘要: 目的 研究猕猴单次静脉滴注注射用枯草芽孢杆菌纤溶酶(BSFE) 的药动学。方法 6 只猕猴静脉滴注BSFE 2 .5 mg/kg, 采用ELISA 法测定动物的血药浓度, 实验数据用DAS 2 .0 药动程序拟合并计算药动参数。结果 6 只猕猴静脉滴注2 .5 mg/kg 的BSFE, 浓度-时间数据经药代动力学参数计算, 表明药物消除符合二房室模型。6 只猕猴的达峰时间(tmax) 均为0 .5 h, 峰浓度(Cmax) 均值为(592 .3 ±150 .9) μg/L ;平均消除t1/2β为(5 .78 ±1 .19) h ;平均清除率(C L) 为(4 .42±1 .19) L · h-1·kg -1 ;药时A UC0 -24 .5 h均值为(557 .1 ±211 .1) μg·L -1·h 。结论 本试验所建立的双抗体夹心ELISA 法, 灵敏度高、特异性强、操作简便, 适于BFS E 的药代动力学研究。

Abstract: AIM: To characterize the pharmacokinetic proper ties of a Bacillus subtilis fibrinoly tic enzyme (BSFE) following intravenous infusion in rhesus monkeys.METHODS: Six mon-keys received sing leintraveno us infusion doses of BSFE at 2.5 mg/kg.Serum concentration of BSFE was measured at various time-point s after dosing by ELISA.Pharmacokinetic parameters were calculated with DAS 2.0 software.RESULTS: The concentration-timepro file of BSFE in monkey s was described by a two-compartment model.The mean time to reach peak concentration (tmax) was 0.5 h.The mean peak concentration (Cmax) was(592.3 ±150.9) μg/L.The mean elimination half-life (t1/2β) was (5.78 ±1.19) h. The mean drug clearance from the serum (CL) was (4.42 ±1.19) L·h-1·kg -1.The mean area under the serum concentration-time curve (A UC0 -24.5 h) was (557.1 ±211.1) μg·L-1·h. CONCLUSION: A sandwich ELISA method is sensitive, high specificity and convenient, sui table for the determination of BSFE in serum and its pharmacokinetics studies.
