[Effect of various methods of oxygenation of the small intestine mucosa on the kinetic characteristics of glucose and glycine transport].
Nutrient transport in the small intestine in different conditions of oxygenation of the mucosa in vitro has been studied using original approaches. New experimental data revealed two types of cellular respiration: basolateral and apical ones. Mucosal, serosal and bilateral oxygenations were shown to affect kinetic characteristics (Kt, Vmax) of glucose and glycine active transport in the small intestine. The effect of starvation on the active transport of glucose in the small intestine in different conditions of oxygenation, is discussed. When passing from satiety to starvation state, active accumulation of glucose in the tissue increased during serosal oxygenation and decreased during mucosal and bilateral oxygenation. Characteristic features of functioning of the two types of cellular respiration were investigated in various periods of starvation.
