摘要: 目的:建立高效液相色谱-质谱检测兔血浆乌头碱、次乌头碱和新乌头碱的方法, 研究兔急性草乌中毒血液灌流后的毒代动力学。方法:普通级健康成年雄性日本大耳白兔8 只, 体重(2. 5 ± 0. 2)kg, 予草乌酒1. 0 mL/kg 灌胃(i. g.)染毒, 染毒后0. 25 h 予血液灌流2 h 。分别于染毒后0. 5、 1、 1. 5、 2、 3、 4、 6、 12、 24 h 取血浆。以高效液相色谱-质谱法检测血浆新乌头碱、乌头碱、次乌头碱的浓度。应用DAS 2. 0 程序计算毒代动力学参数。结果:急性草乌中毒血液灌流后, 新乌头碱毒代动力学参数为:tmax(3. 1 ±0. 8)h、 Cmax (11. 5 ±2. 1)μg/L、 Ka (1. 6 ± 0. 9)h、 Ke (0.13 ± 0. 05)h、 t1/2 (5. 9 ± 1. 7)h、 V/F (85. 4 ± 20. 9)L/kg、 CL/F (10. 28 ±1. 46)L·h-1 ·kg-1; 乌头碱毒代动力学参数为:tmax(3. 2 ±0. 5)h、 Cmax(18. 7 ±5. 5)μg/L、 Ka (1. 2 ±0. 4)h、 Ke (0.10 ± 0. 03)h、 t1/2(7. 5 ±2. 4)h、 V/F (2. 7 ±1. 0)L/kg、 CL/F(0. 25 ±0. 08)L·h-1 ·kg-1; 次乌头碱毒代动力学参数为:t max (3. 0 ±0. 8)h、 Cmax (14. 6 ± 11. 0)μg/L、 Ka(1. 4 ±1. 2)h、 K e(0. 09 ±0. 03)h、 t1/2(8. 3 ±2. 1)h、 V/F (10. 7 ±6. 9)L/kg、 CL/F (0. 85 ±0. 38)L·h-1 ·kg-1结论:急性草乌中毒兔血液灌流治疗后的毒代动力学呈一级吸收的一室模型。

Abstract: AIM:To establish an HPLC/MS method for simultaneous determination of mesaconitine, aconitine and hypaconitine in rabbit plasma, and study their toxicokinetics in wild aconite poisoned rabbits after hemoperfusion. METHODS:Eight health grownup male Japan big ear white rabbits [the body weight (2. 5 ±0. 2)kg] were intragastrically poisoned by wild aconite liquor 1. 0 mL/kg and the hemoperfusion was given for 2 h at 0. 25 h after poisoning. The blood was taken after poisoned 0. 5, 1, 1. 5, 2, 3, 6, 12, 24 h respectively. The concentrations of mesaconitine, aconitine and hypaconitine in plasma were detected by HPLC/MS. The toxicokinetics parameters were calculated by DAS 2. 0 program. RESULTS:The parameters of toxicokinetics for mesaconitine in wild aconite poisoned rabbits after hemoperfusion were as following: tmax(3. 1 ±0. 8)h, Cmax(11. 5 ±2. 1)μg/L, Ka(1. 6 ±0. 9)h, Ke(0.13 ±0. 05)h, t1/2(5. 9 ±1. 7)h, V/F (85. 4 ±20. 9)L/kg, CL/F (10. 28 ±1. 46) L·h-1 ·kg-1. The parameters of toxicokinetics for aconitine were as following: tmax(3. 2 ±0. 5)h, Cmax (18. 7 ±5. 5)μg/L, Ka (1. 2 ±0. 4)h, Ke (0.10 ± 0. 03)h, t1/2(7. 5 ±2. 4)h, V F(2. 7 ±1. 0)L/kg, CL/F(0. 25 ±0. 08)L·h-1 ·kg-1. The parameters of toxicokinetics for hypaconitine were as following: tmax(3. 0 ±0. 8)h, Cmax(14. 6 ±11. 0)μg/L, Ka(1. 4 ± 1. 2)h, Ke(0. 09 ±0. 03)h, t1/2(8. 3 ±2. 1)h, V/F (10. 7 ± 6. 9) L/kg, CL/F (0. 85 ± 0. 38) L·h-1 ·kg-1. CONCLUSION:The toxicokinetics of mesaconitine, aconitine and hypaconitine in wild aconite poisoned rabbits after hemoperfusion are fitted to the one-compartment model with first-order absorption.
