Abstract : Brain slices from the rat were allowed to respire for 2 hr in a modified Tyrode's solution containing the monoamine oxidase inhibitor 1-phenyl-2-hydrazinopropane (alpha-methyl phenyl hydrazine, JB-516). The filtered Tyrode's solution was shown to contain 5-hydroxytryptamine (Serotonin, 5-HT) by both bioassay and fluorometric techniques. Preliminary evidence indicates that the amount of 5-HT in the filtrate is increased significantly by adding reserpine and JB-516 to the incubation medium. These findings suggest that a sensitive bioassay procedure, coupled with the use of brain slices. offers an approach for the study of factors affecting the storage and release of endogenous 5-HT.
