We developed a sensitive microbore HPLC method coupled with an on-line microdialysis system to simultaneously measure endogenous 5-hydroxytryptamine (serotonin; 5-HT) and its major metabolite 5-hydroxyindoleacetic acid (5-HIAA) in the rat blood in vivo. A dialysis tube was placed in the right jugular vein. The validity of the procedure is demonstrated because analysis of the aggregating agents, collagen (1 mg/kg) plus epinephrine (0.3 mg/kg) after intravenous injection, showed that they induced an increase in 5-HT and 5-HIAA levels in the jugular vein of the rat.
