[Morphology of chronic gastritis]

The objective of the paper is the specification of morphological criteria for the diagnostics of chronic gastritis. Biopsies, taken from the antral and corporal mucosa of 317 patients, were studied. Light chronic superficial gastritis was established in 184 cases. Manifested chronic superficial gastritis--in 178 cases, 119 of them in the antrum. Chronic gastritis with initial atrophy of the glands was established in II cases, and complete--in one. Chronic gastritis with intestinal metaplasia was observed in the antral mucosa mainly, and with various degrees of glandular atrophy both in case of the chronic superficial gastritis and chronic gastritis. The chronic gastritis with some changes in the glands, but without atrophy--47 cases, is of particular interest. The intestinal metaplasia as well as the pylorization of the corporal glands in chronic gastritis with changes in the glands without atrophy are a manifestation of dysregeneratory disorders and disturbance in the coordination between the phases of proliferation and differentiation.
