Histomorphological characteristics of accelerated healing of acetate ulcers under the effect of glyprolines.

Glyprolines (PGP, GPG, GPGP, PGPGP, and GPGPGP) modulated histomorphological characteristics of acetate ulcers. They accelerated healing of acetate ulcers, promote complete differentiation of the surface epithelium and glands in the gastric mucosa, contributed to the appearance of a considerable number of fibroblasts at the site of the regenerating mucosa, and significantly decreased the count of macrophages.
