Abstract:
Objective To study the toxicokinetics of phthalates in male rabbits. Methods Concentrations of DEHP or DBP in plasma of 6 healthy male rabbits were determined by RP-HPLC after constant rate infusion of 0.5 g/kg DEHP or DBP(IV). The toxicokinetic parameters were computed by 3P87 program. Results The toxicokinetic model of DEHP and DBP were both first-order elimination and two-compartment model with constant rate infusion. The main toxicokinetic parameters of DEHP were as follows: distribution phose t1/2(?)=0.101 h; elimination phase t1/2(?)=12.701 h; CLs=0.013 g?kg-1?h-1. The main toxicokinetic parameters of DBP were as follows: t1/2(?)=0.441 h; t1/2(?)=31.311 h; CLs=0.021 g?kg-1?h-1. Conclusion DEHP and DBP were both first order elmination and two-compartment medol with constand rate intusion(IV). DEHP and DBP could be rapidly eliminated in male rabbits.
