[Protective effect of the intraperitoneal and intragastric administration of PGP-peptide on ethanol-induced erosions and acetate-induced ulcers in rats].
2004
: We investigated the impact of PGP on ethanol-induced mucosal damages and on the development of acetate gastric ulcers in rats for two ways of introduction--intraperitoneal and intragastric. PGP in the dozes of 0.1, 1 and 10 mg/kg authentically reduced the area of ethanol-induced mucosal damages at intraperitoneal introduction by 43, 70 and 65%, respectively; at intragastric introduction--by 64, 66 and 83%, respectively. Intraperitoneal introduction of PGP in the doze of 1 mg/kg and its intragastric introduction in the doze of 0.1 mg/kg equally reduced the development of acetate gastric ulcers by 73%. Thus, irrespective of the way of its introduction (intraperitoneal or intragastric) and its doze, PGP has a significant protective anti-ulcerous effect and reduces the development of acetate gastric ulcers in rats.
