[Adenosquamous early gastric carcinoma].
A case of early gastric carcinoma with areas of the adenosquamous differentiation is described. The origin of the squamous epithelium in gastric carcinoma is discussed.
[Intestinal metaplasia and stomach cancer].
Foci of intestinal metaplasia of gastric mucosa are known to be heterogeneous both morphologically and functionally, and several types of such metaplasia are now recognized. However, different authors use different criteria for their identification and, moreover, evaluate the signs of metaplasia in different ways. Also, the relationship of different types of intestinal metaplasia to one another and to dysplastic changes in the epithelium and to gastric cancer is a matter of controversy. Variants of intestinal metaplasia with sulfomucin secretion are considered as precancerous states that may give rise to gastric cancer of an intestinal type.

[Morphogenesis of coronarosclerosis in rheumatism].
Post-mortem studies of 72 hearts of persons who when alive had suffered from rheumatism were carried out. A complex genesis of sclerotic processes in the vascular walls was noted. They were occurring as a result of the desorganization of the connective tissue, as well as of "wearing out" of hemodynamic adaptation structures and development of atherosclerosis. The dependence of the character of sclerotic changes in vessels upon the peculiar features of the clinical course of the disease is shown. In cases with a high activity of the rheumatic process and considerable increase in the vascular-tissue permeability the development of hyalinosis was noted, and in cases with a slow course of rheumatism an increased fibrillogenesis was observed. Simultaneously, lesion and perish of the smooth-muscle fibres of the media with outgrowth therein of the connective tissue occurred. The dependence of the extent of atherosclerosis in various branches of the coronary arteries upon a morphofunctional characteristics of this defect was established. The most extensive atherosclerotic lesions were found in those vessels which supplied with the blood the functionally burdened regions of the myocardium. A higher activity of lipolitic enzymes in the vessels and the cardiac muscle was observed in persons with rheumatism, as compared with that in persons free from cardiovascular diseases, and particularly in patients with atherosclerosis.
