Peptide correction of disorders in rat mesenteric microcirculatory system during inflammation.

Abstract

PGP peptide had a protective effect in contractile dysfunction of the rat mesenteric lymph vessels under conditions of inflammation, irrespective of the time of its injection (before or after inflammatory agent). The preventive effect of this peptide is largely determined by its capacity to prevent mast cells activation. PGP injected 2 h after induction of inflammation did not inhibit secretory activity of mast cells, which suggests other mechanisms of its therapeutic action.
