[Pancreatic enzyme spectrum in chronic stress].

In acute experiments on white male rats the enzyme spectrum of pancreas homogenate was studied in the process of 30-day adaptation after 3-hour exposure to the muscular loading (compulsory swimming in the water at a temperature of 32 +/- 1 degree C), the heat (overheating at 40-41 degrees C) and the cold (cooling at -3-4 degrees C). It was shown that the initial periods of adaptation to the factors mentioned (2d-12th day) were characterized by a considerable decrease in the activity of all the enzymes under study. With subsequent adaptation of the animal body to these stresses the enzyme activity level recovered to the initial value (18-24th day) and remained more or less stable up to the end of the experiment (30th day).
