[Use of mathematical models in the analysis of gastric digestion].
Mathematical models of gastric hydrolysis of different proteins were elaborated in dogs. These models consider the spatialtemporal coordinates of distribution of pepsin, hydrogen ions and hydrolysates in the stomach, carry out the analysis of factors determining the gastric digestion. The main part belongs to topography and hydrodynamics of gastric content as well as to pepsin concentration. The concentration of "total hydrolysates" is proposed as the final criterion of the gastric digestion. An algorithm for mathematical modelling of gastric digestion is suggested.
