Localization of Cytochrome Oxidase in the Human Eccrine Sweat Unit.

Phosphomonoesterases in Eccrine Sweat and Their Localization after Prolonged Sweating

“…Such a mechanism, analogous to th at of the renal tubules, has been inferred by many, notably by Lobitz and Mason [11] and Conn [12]. We have also cited the high m etabolic activity of the eccrine duct, as shown by its content of succinate de hydrogenase and cytochrome oxidase, as supporting evidence [13,14]. All these inferences, however, are indirect; if our assumption regard ing the localization of phosphomonoesterases in these cases is correct, this experiment provides the first ocular demonstration of resorption of sweat by the eccrine duct.…”
