[Morphological peculiarities of the adipose tissue and their significance for the ultrasound lipodestruction].

Using the autopsy material obtained from 20 human corpses, the samples of subcutaneous adipose tissue of the gluteal, abdominal, inguino-ileal and axillar areas, as well as the samples of mesenterial, retroperitoneal, mediastinal, pararectal and paranephral adipose tissue was studied histologically. The average sizes of the lobes and of adipocytes were measured, and the degree of the development of connective tissue elements was determined. Adipose tissue was found to have a similar general structural plan in all the areas studied, however the differences were noted in the thickness of the interlobular connective tissue septae and in tissue vascularization. The gluteal, inguino-ileal and anterior abdominal wall adipose tissue had the highest density. The lobules of this adipose tissue possessed the minimal numbers of adipocytes that had the smallest size. The mediastinal, retroperitoneal and paranephral adipose tissue was classified as a relatively loose one. The velocity of lipodestruction depended the degree of the development of connective tissue septae: this process proceed most rapidly in the mediastinal adipose tissue and most slowly--in the gluteal adipose tissue. In all the other areas studied, the duration of lipodestruction was the intermediate one.

[High-intensity ultrasonic destruction of fatty tissue in the course of lymphatic dissection in oncological patients].

The paper discusses experimental findings in support of ultrasound destruction of fat tissue at different sites. Rate of destruction was designed to match that of development of the connective-tissue stroma of adipose tissue and size of adipose cells. Parameters of adipose tissue framework at different sites may be taken into account during extended lymph node dissection using ultrasound liposuction in oncological practice.

[Helicobacter pylori and stomach cancer]. / Helicobacter pylori i rak zheludka.

The neoplasms and gastric mucosa colonization with Helicobacter pylori was studied in 40 stomachs resected for expansive (n = 20) and infiltrative (n = 20) carcinoma using Giemsa staining histological sections, histochemical reactions to oxyreductase, and urease test. In expansive carcinoma of the stomach, H. pylori was identifiable both in the tumour and surrounding gastric mucosa in 70 per cent of cases; infiltrative carcinoma appeared to be associated with gastric mucosa H. pylori in 80 per cent, whereas tumour H. pylori were recordable in 30 per cent of cases, which fact is dependent upon the histological structure of carcinoma. The role H. pylori plays in cancerogenesis is discussed.
