Abstract


The paper presents results of the researches on acetylcholine-acetylcholine esterase system's formation in the stomach of piglets at an age of 1, 10, 21, 30, 60, 120 days. Regularities of age-related changes for transmitter`s acetylcholine content and acetylcholine esterase enzyme activities are identified in different sections of the stomach as diverticulum, cardiac, fundus, pyloric area of stomach. It was found out that age-related changes of acetylcholine - acetylcholine esterase system are of irregular and heterochronic character. There is a relative stability of acetylcholine - acetylcholine esterase activity in the tissues of stomach areas under consideration of both piglet groups that starts from the age of 2 months. Acetylcholine - acetylcholine esterase concentration in the cardiac and fundus stomach area's tissues is relatively stabilized from the ages of 1 month and 2 months. There is no relative stability in the diverticulum and pyloric stomach area's tissues.
