Abstract
An improved flow injection analysis (FIA) method has been developed fo r the determination of trace selenium in biological samples, and this method has been applied to investigate the effect of captopril, an ant ihypertensive drug having a thiol group, on selenium concentrations in the rat blood, liver and urine. After oral administration of captopri l, selenium levels in the blood decreased, while those in the liver in creased significantly. However, no pronounced effect was observed on t he urinary excretion rate. The glutathione peroxidase activities in th e blood and the liver were comparable to the changes in the selenium l evels.
