Radioautographic study of palatine tonsillar cells.

Proliferative and functional (protein producing) activities of palatine tonsillar cells were studied by light radioautography (semithin sections). 3H-Thymidine incorporation demonstrated the dynamics of renewal of palatine tonsillar cell populations in various pathological states. 3H-Uridine labeling objectively evaluated functional activity of different cells and more accurately showed distribution of destructive processes in the organ.

Proliferative activity of adipocytes in adipose tissue tumors.

Electron-autoradiographic study of normal and tumor-transformed adipose tissue (common lipoma and destructive lipoma, i.e. infiltrating and degrading lipoma) showed the capacity of adipose tissue cells in lipomas, especially in destructive lipomas, to proliferation and differentiation. In vivo synthesis of DNA in mature adipocytes not observed previously is described. The role of microvascular wall cells as mesenchymal multipotent precursors in the formation of the adipose tissue is discussed. The involvement of the bone marrow mesenchymal stem cell in this process cannot be ruled out.

Morphological changes in the anterior abdominal wall of rats with peritonitis and implanted synthetic film.

Histological study and electron microscopy of the anterior abdominal wall and laparotomy wound closed using a polytetrafluoroethylene film was performed on rats with experimental peritonitis. We studied 4 types of polytetrafluoroethylene films differing in the size of micropores and technology of treatment. The tissue response differed after implantation of various films. A multilayer film with minimum size of pores was optimal to repair the laparotomy wound.

[Radio-frequency ablation appliance in resection of the liver].

Pilot experience with "Radionics Cool-Tip RF System" appliance for radio-frequency ablation (RFA) in hepatic resection in the patients with focal lesions of the liver is presented. Advantages of RFA as an alternative method for hemostasis are demonstrated. With this technique bisegmentectomy (II - III) was performed in 4 patients, right-sided hemihepatectomy - in 2 patients. RFA permitted to minimize intraoperative blood loss without increase of surgery time. There were no severe complications during surgery and in early postoperative period. The method permits to perform combined surgeries without a significant increase of surgical risk.

Structural and metabolic characteristics of liver acini in dogs with acute cholecystitis.

Structural and metabolic changes in liver tissue in dogs with acute cholecystitis were studied by histological, histoenzymatic, and biochemical methods. It was found that the development of destructive inflammatory processes in the gallbladder wall induces morphological damage to the liver tissue, which correlates with metabolic disorders in this organ and leads to liver dysfunction.
