Abstract
Stimulation by pilocarpine led to a marked increase in amylase activity in the submadibular and sublingual glands and serum, and resulted in a considerable depletion of the enzyme in the parotid gland and pancreas of rats. Parotidectomy reduced these pilocarpine effects. It is conluded that amylaser released by pilocarpine from the parotid gland but not from the pancreas elevated the nzyme activity in the submandibular and sublingual glands.
