[Morphological and immunohistochemical characteristics in endometrial hyperplasia].

The development of different types of endometrial hyperplasia is associated with the changes in the proliferation/apoptosis ratio, with the former being predominant in the presence of increased neoangiogenesis and altered endometrial cell receptor status.

[A role of growth factors in development of various histological types of uterine leiomyoma].

The following growth factors play a role in the development of uterine leiomyoma: EFR- epidermal growth factor, EFR-R- receptor of EFR, TGF- thrombocytic growth factor, TGFb- transforming growth factor beta, ILGF1 - insulin-like growth factor of the 1st type. These factors stimulate proliferation of cells, stroma and angiogenesis in the tumor. Mitotically active leiomyoma is characterized by a higher content of these growth factors vs ordinary and cellular leiomyomas.

[Clinico-economic evaluation of cost effectiveness of treatment of inpatients with ulcers].

The treatment efficiency was estimated in 128 patients with peptic ulcer (65 patients were treated in policlinic in daily hospital and 63 patients were treated in usual hospital). It was demonstrated that the duration of treatment in daily hospital was average reduced on 4.8 days and treatment value in daily hospital was lowered on 49%.

[Pathology of the joints of the hand and periarticular tissues in exposure to local vibration and functional overload of the hands].

The hand joint is a multi-joint formation, including the wrist, carpal, intercarpal, carpometacarpal, intermetacarpal, distal radioulnar joints. Features of hand joint and periarticular tissue disease were studied in 536 workers exposed to local vibration and functional overstrain. The most prevalent diseases are arthroses with deformation of the wrist, radiocarpal, carpometacarpal joints, often with involvement of the triangular fibrous disk and carpals, periarthroses of the hand joint with compression neuropathy of the median and ulnar nerves.

[Role of lipids in the acid resistance of saprophytic mycobacteria].

The resistance of saprophyte mycobacteria to acids increases on a medium containing paraffin. The content of free lipids and mycolic acids in the cells of Mycobacterium convolutum assimilating the hydrocarbon increases cf. that in the cells grown on meat-peptone broth.
