[Phenomenon of formation of structures in the dense fraction of the enteric milieu when its pH is changed].
Morphological study of the dog duodenum and ileum contents revealed that the food particles of less than 2 mm size constituted not more than 30% of the total volume of the chyme dense fraction. The main part of the dense fraction consists of the gel structures precipitating in the enteral milieu during changes of its pH due to acid content of the stomach. Histochemical reactions of these structures reveal presence of mucopolysaccharides, proteins and lipids. As the surface of these structures is able to adsorb the digestive enzymes, the intensive digestion of small food particles seems to be due to an increase of the enzyme hydrolysis occurring on the chyme dense fraction structures which are being formed during changes of the enteral milieu pH.
