[Kidney allotransplantation from the AB0-incompatible donors].

The experience of 28 kidney allotransplantations from the AB0-incompatible donors was analyzed. The comparative group consisted of 38 patients, who received the AB0-compatible organ. The results were assessed using the following parameters: renal function, morphology of the biopsy samples of the transplanted kidney and actuary survival of the recipients with functioning transplants in both groups.

Myeloperoxidase modulates human platelet aggregation via actin cytoskeleton reorganization and store-operated calcium entry.

Myeloperoxidase (MPO) is a heme-containing enzyme released from activated leukocytes into the extracellular space during inflammation. Its main function is the production of hypohalous acids that are potent oxidants. MPO can also modulate cell signaling and inflammatory responses independently of its enzymatic activity.

[Effect of clarithromycin on the systemic inflammatory response syndrome severity in patients after myocardial revascularization surgery].

The aim is to investigate the effectiveness of SIRS pharmacological correction in patients after CABG when adding clarithromycin to the standard antibacterial therapy. Patients of the 1st group (n=25) received Klacid- CP ("Abbott") in perioperative period plus to standard antibacterial therapy (3rd generation cephalosporins), patients of 2nd group received standard therapy. At 1st screening stage, as well as on the 2-nd and 4-th day after operation were recorded data of an anamnesis, concomitant pathology, examination, were measured the level of white blood cells, LII, biochemical blood analysis (CRP), defined the concentration of interleukins (IL-1, 6, 8,10,12) and TNF - a.

[The kidney transplantation from the ABO-incompatible donors].

The experience of 28 allotransplantations of ABO-incompatible kidneys was compared with the treatment results of 38 ABO-compatible renal transplantations. The transplanted kidney function, morphological changes of the transplanted kidney and the comparative analysis of actuary survival in both groups showed no significant difference. The results of the study prove the validity of the kidney transplantation from the ABO-incompatible donors.

[Glutathione-dependent regulation of platelet aggregation with neutrophils and tumor cells].

It is shown that in the presence of reduced glutathione at low concentrations (1-5 microM) the extent of platelet aggregation with neutrophils increases and the lag period of platelet aggregation induced by tumor cells decreases. At the same time in the presence of reduced glutathione at high concentration (3 mM) the extent of platelet aggregation with neutrophils decreases, and the lag period of platelet aggregation induced by tumor cells increases. It is established that glutathione-dependent regulation of the intercellular contact formation between platelets and neutrophils depends on the ratio of glutathione oxidized and reduced forms: at fixed total glutathione concentration of 5 microM, increase of glutathione redox potential from -175 mV to 0 mV led to reduction in platelet aggregation with neutrophils.
