EXPERIMENTAL STUDY OF THE ANTIDIARRHOEAL ACTIVITY OF MONTMORILLONITE-CONTAINING ENTEROSORBENT

Abstract

Aim. To study the antidiarrhoeal activity of montmorillonite-based enterosorbent on the model of serotonin-induced diarrhea. Materials and methods. The study was performed on laboratory mice of both genders, acute diarrhea was induced by intraperitoneal injection of serotonin hydrochloride at a dose of 0.32 mg/kg, enterosorbent as an aqueous suspension was administered orally in a wide range of doses 30 minutes prior to serotonin administration. Within 4 hours, the time of diarrhea onset, the number of defecations, the fluid content in the fecal masses was considered. Morphological examination of the small intestine was carried out. Results. The administration of serotonin led to the development of diarrhea in 100% of animals in 12,8±1,2 minutes, the number of defecations increased 2,5 times compared to intact animals and was 19,5±0,5 times within 4 hours, the fecal masses were predominantly wet and liquid. The use of enterosorbent under the Crim_04 cipher in the maximum dose led to a delay in the development of diarrhea to 73,6±4,1 minutes, a reduction in the number of defecations to 9,4±0,1 and a significant inspissation of stool. The antidiarrhoeal effect of enterosorbent was confirmed morphologically. Conclusions . Montmorillonite-based enterosorbent under the laboratory cipher Crim_04 has a dose-dependent antidiarrhoeal activity in the modeling of serotonin-induced diarrhea.
