title: [Lysosomal enzyme activity of the gastric mucosa in rats during experimental ulcer formation].
abstract: Lysosomal membrane stability has been studied in the gastric mucosa in response to mechanical damage caused by lysosomal fractionation and release of lysosomal enzymes from mucous cells into the gastric cavity of alive animals during induction of acetic ulcer or erosive damage of the gastric mucosa resulting from intraperitoneal introduction of histamine and serotonin. It has been found that all types of ulcerogenesis in the gastric mucosa led to the decrease in lysosomal membrane stability to mechanical stress in the course of lysosomal fractionation. In addition there was a substantial release of lysosomal enzymes into the gastric cavity in different types of ulcerogenesis. The decrease in lysosomal membrane stability combined with a subsequent development of ulcers and erosions in the gastric mucosa seems indicative of the fact that lysosomal enzymes take part in the initial formation of ulcers in the gastric mucosa.
