Summary
-
1.
The distribution of cholinesterase in the parotid salivary gland has been studied histochemically in 21 mature rats.
-
2.
A large amount of true and pseudo cholinesterase activity was found to be present throughout the cytoplasm of the secretory cells.
-
3.
Cholinesterase activity was also seen in moderate amounts in the nerve trunks accompanying the inter- and intralobular ducts and blood vessels.
-
4.
Postganglionic sympathectomy was found to have no effect on the activity of cholinesterase in the secretory cells and nerve trunks.
-
5.
The significance of these findings is discussed.
