The innervation of human axillary sweat glands was studied by using the specific SPG (sucrose-potassium phosphate-glyoxylic acid) catecholamine histofluorescence method and the peroxidase-antiperoxidase (PAP) immunocytochemical method. The present results demonstrated that human sweat glands are surrounded by nerves containing a
