[Effect of hypoxia on gastric secretion of hypovolemic rats]

Gastric secretion was checked in two groups of rats with pyloric ligature and experimental hypovolemia subjecting one of the groups to acute hypoxia; in this group there was significant decrease in volume, acid and pepsin secretion and potassium concentration in gastric contents. In gastric mucosa pepsinogen was increased. We wish to emphasise in these changes, the importance of water and hypoxia in electrolytic balance.
