The process of aging of the human organism is accompanied by certain changes in the regulation of the secretory activity of the stomach. This applies to the neural mechanisms of regulation just as much as to the humoral ones. Quite often such changes are opposed. The significance of cholinergic mechanisms is reduced whereas that of adrenergic mechanisms is(More)
For studying the changes in the gastric secretory capacity that are caused by old age, the double-pentagastrin test is recommended; this test serves to examine the gastric secretory reaction by administering twice pentagastrin in a dose of 6 micrograms/kg. With this suggested method it was possible to find out the age-dependent decrease in the functional(More)
The motor function of the stomach in the fasting condition and in the presence of a conditioned food stimulus has been studied in practically healthy elderly and aged subjects. As the investigations have shown, gastric motoricity changes during the process of ageing in that there is a decrease in the tonus in the various sections of the stomach, and in(More)
