[Secretory activity of the stomach during modeling of increased filling of abdominal veins].
Determination of the stomach secretory activity and ultrasonic investigation of the gastroduodenal organs and vessels were performed in test-subjects tilted at -12 degrees and -15 degrees. Short HDT(12-24 hrs.) as a hypokinesia factor was minimized which caused enlargement of the parenchymatous and thickening of walls of the hollow organs. Increased filling of the abdominal veins was paralleled by rise in pepsinogen levels in blood and urine, and increase in the intravitelline content in fasting subjects. Elevated tone of the pylorus and retarded evacuation from the stomach indicated active hydrochloric acid secretion. Concurrently, bile and pancreas juices were secreted more profusely and intestinal content in the duodenum increased. It was shown that modeled increase of abdominal vein filling stimulates secretion as by fasting stomach so by the liver and pancreas.
