title: Acute gastric mucosal ulceration in septic shock. An experimental study on pathogenic mechanisms.
abstract: Intravenous infusion of live. E. coli bacteria in cats did not induce microscopic damage to the gastric mucosa within 3 hours. However, if the cats before the induction of bacteremia were given 80 mM HCl and 0.6 ml gallbladder bile/kg b.w. microscopic mucosal damage developed regularly in the corpus-fundus area of the stomach. The gastric mucosal damage was not associated with significant decrease of total gastric blood flow as measured continuously electromagnetically or decreased gastric mucosal blood flow measured early and late during sepsis using radioactively labelled microspheres. Neither was the development of gastric mucosal damage associated with reduced gastric wall collagen concentration nor in RNA, DNA concentrations or RNA/DNA ratio in the gastric mucosa.
