A preliminary note on the adrenergic mechanism of sweat secretion and the sweat electrolyte concentration in man.

A role of the adrenergic mechanism on the sweat electrolyte concentrationshave been suggested in our previous study", in which the elevated sodium and chloride concentrations in the human palmar sweat induced by emotional stress, or in the human body sweat induced by physical exercise, were observed. The role of the adrenergic mechanism on the sweat electrolyte secretion and reabsorption was further classified into the alpha and beta adrenergic receptor mechanisms to produce a high sodium•\low potassium sweat or a low sodium•\high potassium sweat, in our previous study on the palmar sweat of the monkey who received continuous intravenous infusion of noradrenaline, adrenaline, dibenzyline, isoproterenol and inderal, combined with subcutaneous injection of pilocarpine, respectively2). The present studies deal with the electrolyte concentrations (Na, K and Cl) of the human body sweat produced by the combination of noradrenaline and pilocarpine, or by the combination of adrenaline and pilocarpine, to investigate the role of the alpha and beta adrenergic receptor mechanism on the sweat electrolyte concentrations in man, if there is any at all.
