Effect of 5-Hydroxytryptamine on Sodium Transport across Bullfrog Skin
5-hydroxytryptamine (5 HT) has been shown to promote the reabsorption of sodium by the renal tubule (Blackmore 1958, Little et al. 1961); it is also considered as an inhibitory transmitter substance in the central nervous system (Brodie and Shaw 1957, Twarog 1954). Despite these and other important rôles played by 5HT, its effect on membrane permeability and transport in relatively well-defined systems is not known. Hence, this investigation was undertaken to study the effect of 5HT on sodium transport across frog skin.
