[Levels of various lipid fractions in mucosa tissues of the rat oral cavity in experimental gastrointestinal pathology].

The content of main lipid fractions was determined by thin-layer chromatography in mucosa tissues of the rat oral cavity under chemical damage of the stomach, large intestine and extrahepatic cholestasis. A decrease in the amount of phospholipids, free fatty acids, free cholesterol, di- and triglycerides is found in the mucosa of the animal oral cavity independently of the character and level of the gastrointestinal tract damage. There are topographic differences in the extent and manifestation of the observed disorders.
