PHARMACOLOGICAL CORRECTION OF EXPERIMENTAL GASTRIC ULCER BY A NEW HERBAL AGENT

The aim of the study was to study the effect of liposome emulsion with grape seed polyphenols (LEGSP) on the secretory and motor-evacuatory functions of the gastrointestinal tract and efficacy in experimental gastric ulcer. Materials and methods. The experiments were carried out on 36 white non-linear male rats weighing 180–220 g and 12 white non-linear mice weighing 18–20 g of different sexes. The effect of LEGSP on the secretion of gastric juice was assessed in terms of total, free and associated acidity of gastric contents; on the motor-evacuation function of the gastrointestinal tract – according to the percentage of intestinal length passed by the contrast mass from the absolute intestinal length. Evaluation of the antiulcer activity of the emulsion was carried out according to macroscopic indicators of the intensity of the formation of ulcerative defects in the gastric mucosa. Statistical processing of the results was carried out using parametric and nonparametric methods of analysis. Differences between the control and experimental groups were considered statistically significant at P < 0.05. Results. It was found that for 4 hours of the experiment under the influence of LEGSP the secretion of gastric juice decreased by 12.7 % relative to the group of intact animals. Total, free and associated acidity decreased by 33.3 %, 41.4 % and 24.2 %, respectively. That is, the use of LEGSP leads to a moderate suppression of the acid-producing function of the stomach. An increase in the motor function of the intestine was also observed with the introduction of LEGSP to mice, as evidenced by an increase in the relative index of the intestinal length passed by the contrast agent by 28.5 % compared with the intact control. In the experimental group, which received LEGSP, the average area of ​​erosive damage areas decreased by 3.7 times and amounted to (5.7 ± 0.5) mm2. The ulcerative index is 1.4; antiulcer activity – 93.4 %. Conclusions. A new herbal remedy based on grape seeds (LEGSP) leads to the suppression of the acid-producing function of the stomach, stimulates the motor-evacuation function of the intestine and has high antiulcer activity in the model of acute serotonin gastric ulcer.
