title: Phosphatases in the lingual glands of man and dog.
abstract: Phosphatase activity was demonstrated in the lingual glands of man and dog. Especially the ducts of the glandular elements of the dog exhibited a peculiar and rather perplexing pattern of activity which does not seem to fit in with any of the prevailing concepts of the function of the duct system. The secretory capillaries (Sekretionscapillaren) in many of the serous acini of the human lingual glands have demonstrated phosphatase activity with all the 17 substrates used. The significance of these phosphatases, expecially ATPase, in the active transport across biological unit membranes has been discussed.
