Palmar or Plantar Sweat Electrolyte Concentration in the Monkey. II

Palmar or plantar sweat of the monkey induced by the combination of pilocarpine and adrenaline, revealed Na-concentration, Cl-concentration and Na/K ratio higher than the control sweating induced by pilocarpine alone. Sweat induced by the combination of pilocarpine and adrenaline, also revealed Na- and Cl-concentrations as well as Na/K ratio higher than the control, but not as significantly as in noradrenaline sweating. The Na/K ratios in noradrenaline sweating and adrenaline sweating are both greater than 1.0, revealing parallel increase with increasing sweat rates, but Na/K ratios at the same sweat rates were revealed always greater in noradrenaline sweating than adrenaline sweating.Palmar or plantar sweat of the monkey induced by the combination of pilocarpine and dibenzyline, or by the combination of pilocarpine and isoproterenol, revealed decreased Na- and Cl-concentrations as well as decreased Na/K ratios smaller than 1.0 which decrease along with increasing sweat rates.Palmar or plantar sweat of the monkey induced by the combination of pilocarpine and inderal, revealed increased Na- and Cl-concentrations as well as increased Na/K ratios greater than 1.0 which increase along with increasing sweat rates.On the basis of these findings on the palmar or plantar sweat of the monkey, and of the similar findings in the sweat of the human general body surface, α- and β-adrenergic mechanisms to produce a high Na-low K sweat and a low Na-high K sweat, was suggested to exist in the sweat gland of the monkey as in man.
