[Evaluation of the results of reconstructive operations in patients with occlusive diseases of the abdominal aorta and its branches]. / Otsenka rezul'tatov rekonstruktivnykh operatsii u bol'nykh s okkliuzionnymi zabolevaniiami briushnoi aorty i ee vetvei.

The article deals with the results of studying regional microcirculation in 550 patients with chronic arterial insufficiency. Radioisotope study of blood flow in the muscles with isotopes 131I or 133Xe before and after muscular exertion, morpho-histological++ study of biopsies from a skeletal muscle, histochemical and ultrastructural study of the microcirculatory channel were carried out. Analysis of the findings made it possible to distinguish, according to the changes in circulation in the tissues, three clinical groups of patients (compensated, subcompensated, and decompensated), to determine the indications and contraindications for various types of reconstructive operations, and to prognosticate with high authenticity the outcome of the disease.

[Colonoscopy in the diagnosis and treatment of small colonic polyps]. / Kolonoskopiia v diagnostike i lechenii melkikh polipov tolstoi kishki.

The results of treatment of 801 patients are analysed. It is shown that the probability of growth and the development of new adenomas or a recurrence of the disease is higher in patients with multiple small polyps and in their combination with larger structures. Therefore, all multiple structures in the colon, irrespective of their size, must be removed endoscopically without fail and the patients kept under dynamic control subsequently. Solitary small polyps show no tendency to grow, in view of which the therapeutic tactics in such cases should be individualized and determined by the histological structure of the growth themselves and the character of the changes in the colon.

[Treatment of polyps and villous tumors of the large intestine]. / Lechenie polipov i vorsinchatykh opukholei tolstoi kishki.

Polyps and villous tumors were found in 1525 of 10624 patients (14.3%) aged from 40 to 60. In 82% of the cases they were in combination with ulcer disease of the stomach and duodenum, with inflammatory diseases of the gastro-intestinal tract, diverticulitis, tumors of the colon. 1519 polypectomies and dissection of villous tumors both via the fibroscope, rectoscope and by transanal access were made. Complications were obtained in 5 patients, recurrent disease was noted in 3 patients (0.9%).

[Morphofunctional preservation of islet cells of the guinea pig pancreas during subculture]. / Morfofunktsional'naia sokhrannost' ostrovkovykh kletok podzheludochnoi zhelezy morskoi svinki pri ikh subkul'tivirovanii.

The authors studied the possibilities of long-term culture of islet cells of guinea-pig pancreas by passages. beta-cells of guinea-pig pancreas were cultured for 180 days and underwent 6 passages. Morphological and radioimmunological studies of long-term-viable cells of the pancreas have shown that regular passages enable the obtaining of a homogeneous population of beta-cells. During all the passages, the cells preserve the morphological and functional features of islet tissue.
