  • Title: [Characteristics of the motor function of the proximal segment of the gastrointestinal tract].
    Author: Virchenko SB, Kucherenko TL.
    Journal: Fiziol Zh (1978); 1989; 35(3):32-8. PubMed ID: 2737325.
    Abstract:
    Dynamics of the solid carbohydrate food evacuation from the duodenum has been determined in chronic experiments on dogs using modified technique for multiple drainage of intestinal fistulas. It is established that dynamics of the duodenal chyme emptying depends on the absolute quantity of the stomach-evacuated food and includes three phases: increase in the evacuation rate, exponential phase and that of accelerated evacuation. The highest rate of the duodenal contents is observed in the period from the 90th to 210th minute after food intake, the lowest one--at the end of the digestive cycle. A conclusion is made concerning the high degree of coordination of the evacuatory stomach and duodenum function.
