[Gastric secretion in hypovolemic rats caused by acute hemorrhage]. 1977

B Cannata, and E Agüero, and H Peralta, and O Mateo, and J R Suárez

Gastric secretion was studied in two groups of rats in which pyloric ligature with wire was previously peformed. One of the groups was acutely bled until hypovolemia. The following parameters were checked: gastric volume, acid and pepsin secretion, Pu/g of stomach, chloride, potassium, and sodium. A significant decrease in volume, acid and pepsin secretion, Pu/g of stomach and chloride and increase in potassium in the hypovolemic rats found. There was no significant change in sodium concentration. There was no significant difference in the pepsinogen concentration in gastric mucous between both groups of rats.

D005750 Gastric Juice The liquid secretion of the stomach mucosa consisting of hydrochloric acid (GASTRIC ACID); PEPSINOGENS; INTRINSIC FACTOR; GASTRIN; MUCUS; and the bicarbonate ion (BICARBONATES).

D005753 Gastric Mucosa Lining of the STOMACH, consisting of an inner EPITHELIUM, a middle LAMINA PROPRIA, and an outer MUSCULARIS MUCOSAE. The surface cells produce MUCUS that protects the stomach from attack by digestive acid and enzymes. When the epithelium invaginates into the LAMINA PROPRIA at various region of the stomach (CARDIA; GASTRIC FUNDUS; and PYLORUS), different tubular gastric glands are formed. These glands consist of cells that secrete mucus, enzymes, HYDROCHLORIC ACID, or hormones.
