Abstract:
:Amylase activity in various tissues--i.e., submandibular/sublingual and parotid glands, the pancreas, saliva, and serum--in rats was measured after injection of isoproterenol, pilocarpine, and acetylcholine. All agents reduced amylase activity in the parotid gland and increased the enzyme activity in the submandibular/sublingual glands, in saliva and serum.
