摘要

The effects of 8018 [3-(2'-phenyl-2'-cyclopentyl-2-hydroxyl-ethoxy)quinuclidine] on the elimination of soman in rabbits blood and distribution in mice brain and diaphragm were investigated using the chirasil capillary gas chromatographic analysis method. In all experiments, the concentration of P(+)soman was below the detection limit (< 0.1 ng.mL(-1)). 8018 (1 mg.kg(-1), im, 10 min pre-treated) could significantly reduce the concentration of P(-)soman in rabbit blood from 53.6 +/- 13.3 to 26.2 +/- 9.70 ng.mL(-1) blood as compared to soman-treated control animal at 15 s following soman injection(43.2 mug.kg(-1), iv). Toxicokinetic parameters showed 8018 could increase clearance (CL(s)) from 20.8 +/- 1.54 to 38.2 +/- 15.3 mL.kg(-1).s(-1) and reduce AUC of P(-)soman from 2.08 +/- 0.151 to 1.30 +/- 0.564 mg.s.L-1. 8018 could reduce the concentration P(-)soman in diaphragm from 74.7, 70.5, 88.7 ng.g(-1) to 54.5 45.6, 50.0 ng.g(-1) at the time of 30, 90, 120 s after intoxication of soman subcutaneously vs. soman control respectively, but it had no influence on the concentration of free P(-)soman in brain. Isotope trace experiments showed that it could significantly increase the distribution amount of bound [H-3]soman in mice plasma and small intestine during 0-120 min after mice received [H-3]soman (0.544 GBq.119 mug.kg(-1), sc) compared to soman control group.
