Summary

Experimental data of the study of cholinesterase activity in the smooth muscles of normal and depancreatized frogs are presented. Variations in the activity of cholinesterase of smooth muscle organs of frogs are insignificant during the autumn-winter season. However, the activity of cholinesterase considerably increases during the spring season (March–April).

Increased activity of cholinesterase is, likewise, observed in depancreatized frogs. It coincides with the time of derangement of the parasympathetic influence on the organs and tissues during the postoperative period. Compensatory introduction of acetylcholine to operated frogs prevents the increase of cholinesterase activity.

It is probable that increased cholinesterase activity in tissues and organs of frogs is one of the factors of parasymphathetic disturbance in depancreatized frogs.
