In this experiment, sodium selenite solution were used as single oral dos-ing infusion(0.6mg/kg body weight) and the blood samples were collected in differenttimes. The selenium concentration in blood was measured by fluori-spectrophotometer。The true value of selenium concentration in blood were processed with MCPKP which isspecially designed for pharmacokinetics on microcomputer and by which we obtained thetheoretical value of selenium concentration in blood and pharmacokinetics parameters。The blood seleni...
