[Secretion of pepsinogen, amylase and alkaline phosphatase by human sweat glands]

Human sweat contains pepsinogen, amylase, and alkaline phosphatase excretion of which depends on functional state of the digestive and sweat glands and on the topography of latter. Pepsinogen excreted with sweat has the gastric origin. Different food irritants activate amylase and alkaline phosphatase excretion with sweat. A high positive correlation exists between amylase and pepsinogen excretion by kidneys and sweat glands in healthy subjects.
