Influence of portal vein and liver artery ligation on the toxicokinetics of soman in rabbits.

摘要

The portal vein, liver artery ligation treatment and the portal vein ligation treatment could increase the concentration of P(-) soman in rabbit blood 3.6-19.3 times as compared with soman control group at each time points after soman injection (43.2 microgkg(-1), i.v.). Toxicokinetics parameters showed that portal vein, liver artery ligation treatment and portal vein ligation treatment could reduce the clearance (CL) and distribution volume (V(d)). Meanwhile, they could significantly increase the AUC of soman in rabbits from 2.08+/-0.154 to 18.2+/-2.96 and 22.9+/-3.73 mg s l(-1), respectively. All these data showed that the liver and intestine play a very important role on elimination the free soman in rabbit's blood at high dosing of soman.
