MORPHOFUNCTIONAL CHARACTERISTICS OF STRUCTURAL CHANGES IN GASTRIC BLOOD VESSELS AFTER REMOVAL OF MANDIBULAR AND PAROTID GLAND IN RATS
Ilya Ye. Herasymyuk and Olexander A. Bedenyuk*
ABSTRACT
A significant number of scientific works are devoted to study of salivary glands role in maintaining the normal functioning of the human body and ensuring a systematic welfare, but this problem is not fully explored. As to pathogenetic connection between salivary glands affections and other diseases of the gastrointestinal tract organs, most of the studies considered it from the position of the secondary oral cavity pathology, which develops against other digestive diseases while anatomically and functionally a reversed approach would be more logical and consistent. We should take into account the fact that one of the priorities of modern morphology is to establish character and features of the circulatory system restructuring under the disturbed conditions of hemocirculation as an important link in the development of pathological processes. Remove of the parotid and mandibular glands in rats accompanied by significant remodeling of stomach blood vessels that is the progressive strengthening of blood supply with same time increasing of vascular resistance in organ during the 21th day after operation. From 21th to 28th day of the experiment, there is a partial regression of morphofunctional state of stomach bloodstream, which may be caused by compensatory hyperplasia and hyperfunction of other localization of salivary glands of other located salivary glands which are left (sublingual, buccal, gingival and lingual).
Keywords: salivary glands, stomach, Vohenvort index, remodeling, blood vessels.
