[[Impact of plestazol preparation on hyperplasia of inter vascular layer in the patients, suffering obliterating atherosclerosis of the lower extremities arteries after reconstructive operations].]

In the clinic 60 patients were examined, in whom reconstructive operations on the main arteries were performed for obliterating atherosclerosis (OA) of the lower extremities vessels. Efficacy of impact of Plestazol (in a 200 mg/day dose) on neointima hyperpla- sia was studied. Clopidogrel (75 mg/day) was administered to patients of comparative group. Effective criteria for estimation of the migration-proliferation disorders state in endothelial dysfunction are concentration of the intercellular adhesion molecules (ICAM) and the basic factor of the fibroblasts growth (FGFb); morphological disorders in hyperplastic reactions of neointima - determination of thickness of "intima-media" complex in accordance to the ultrasound duplex scanning data. There was established, that Plestazol constitutes an effective disaggregate preparation, positively impacting decelerating reaction of neointima hyperplasia, including, deceleration of the smooth- muscle cells migration into subendotelial layer in the formation zone of the femoro- popliteal shunt distal anastomosis.

[Cross-reacting antigens of pathogenic Burkholderia and some dangerous causative agents of infectious diseases].

Cross-reacting antigens in B. mallei, B. pseudomallei, B. thailandensis, Francisella tularensis, Yersinia pestis and Mycobacterium tuberculosis were studied with the use of immuno- and electrophoretic techniques. The set of antigens was shown to be almost identical in the causative agents of glanders, melioidosis, as well as in B. thailandensis, though in the latter organism 200-kD glycoprotein was absent. The analysis of immuno- and proteinograms demonstrated the presence of cross-reactions in the representatives of the genus Burkholderia with the causative agents of plague, tularemia and tuberculosis, which served as the basis for making the scheme of their antigenic relationships. The use of immunosorption techniques with subsequent analysis of the preparations by means of the SDS polyacryl gel electrophoresis and immunoblotting made it possible to characterize cross-reacting antigens of the pathogenic microorganisms under study, to establish their molecular weights (81-15 kD) and to show that some detected antigens are analogous to B. pseudomallei outer membrane proteins (34 and 30 kD).
