[Protective effect of the intraperitoneal and intragastric administration of PGP-peptide on ethanol-induced erosions and acetate-induced ulcers in rats].

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.

[Highly stable regulatory oligopeptides: experience and applications].

The most stable regulatory peptides (RP) including the new family of RP (glyprolines) and derivatives of hybrid peptide MEHFPGP are characterized. High ability of glyprolines to penetrate into the blood-stream through the gastrointestinal tract is demonstrated. Antiulcer, antithrombotic and antidiabetic activities of glyprolines were discovered in experiments on white rats.
