Purpose of the study. Study of the activity and topography of enteral enzymes in rats of mixed, non-aggressive and aggressive groups under conditions of immobilization stress.
Material and methods. The experiments were carried out on adult outbred rats weighing 180-200 g. Animals were tested for aggressiveness. Immobilization stress was induced by forced immobilization for 24 hours. The activity of digestive enzymes was determined. Statistical data processing was carried out according to the Student-Fisher method. Results. Depending on the behavioral characteristics of animals, there are variations in the activity and topography of enzymes throughout the small intestine. These parameters are close to each other in rats from the mixed and non-aggressive groups, while in aggressive individuals there is a different picture, sharply different from the two groups described above: the activity of enteral enzymes, except for lactase, is higher and the topography of enzymes is different.
