Objective To investigate the effect of antidepressant drugs on serotonin (5HT).Methods 5HT immunoreaction in rats brain was detected after the acute and chronic adminisstration of four antidepressant drugs by immunohistochemistry methos.Results The results showed that: (1) Only fluoxetine could decrease the 5HT immunoreaction in cornu ammonis and thalamas in rat brain in the acute group; (2) Four antidepressant drugs could decrease 5HT immunoreaction in six regions of rats brain in the chronic group. Conclusions It was suggested that four antidepressants might inhibit 5HT reuptake in various degrees and decrease the 5HT concentrations in intraneuron.
