[Preservation of the components of blood and bone marrow for autotransfusion in patients of a particular risk contingent].

Cryopreservation is the method of choice in solution of the problem of the done in good time reservation of the components of blood and bone marrow for autotransfusion in patients referred to the contingent of particular risk. Freezing of autologous hemocomponents increases the infection safety and efficiency of therapy with hemocomponents. The wide introduction of using autologous hemocomponents into the everyday surgical practice and in the arsenal of means and methods of the medicine of extreme situations is an indispensable condition for increasing the effects of curative and medico-evacuational measures.

[Blood transfusion support in rendering medical care in extreme conditions].

About 20% of accident and disaster victims need the hemotransfusion therapy. At present the method of erythrocyte long-term storage in the blood banks with glycerin high concentration is the most acceptable one. There are special medical teams (SMT) in the districts. They include the transfusiologic group with appropriate reserve of hemotransfusion materials. Most of them must be stored as untouchable reserve in the institutions of blood service and large hospitals on which the SMTs are based.

[Structural and functional changes of bone marrow stroma in chronic lymphocytic leukemia].

Marrow stroma was investigated in 20 patients with chronic lymphocytic leukemia (CLL). Such morphological and functional features as adipose tissue reduction, sinusoid pattern obliteration and increased number of reticular cells were identified as typical of marrow stroma in such patients. Foci of fibrosis, nuclear bodies in stromal cell nuclei and heightened proliferation of stromal precursors in organ cultures were recorded in the subendostal and perivascular areas in 60% of patients with diffuse lesions of bone marrow. Bone marrow stroma was shown to suffer morphological and functional changes which were particularly pronounced in diffuse lesions of the bone marrow. Such changes may be traced both to the malignant clone of lymphoid cells and stromal lesions.

[Morphologic and functional features of hemopoietic microenvironment in acute lymphoblastic leukemia].

Data of the histological, ultrastructural and culture cell investigations of bone marrow microenvironment in 20 patients with acute lymphoblastic leukemia (ALL) are presented. Morphological and functional peculiarities of the patients' bone marrow stroma different from that in healthy subjects were identified. They included distorted histotopographic patterns of stroma-hemopoietic cell-to-cell interaction, obliteration of sinusoid counts, resorption on the sites of internal bone support structures, a changed stromal cells ratio, formation of reticular cell clusters in the subendosteal and perivascular bone marrow areas, fibroid centers, the presence of nuclear bodies in stromal cell nuclei and an intensified proliferation of stromal cell precursors in organ tissue cultures. Morphological and functional changes in bone marrow microenvironment were detected in ALL patients, which could have been caused both by malignant cell clones and stromal defects.

[A syphilis marker study of blood component donors].

Laboratory testing of donor blood is the key point in prevention of hemotransmissive syphilis. The probability of using diagnostic EIA kit RecombiBest antipallidum-strip (AO Vektor-Best, Novosibirsk) is assessed. Ninety-two donor sera were tested. For assessing the sensitivity of the test system, 11 sera of syphilis patients were titrated by double dilutions 1:10 to 1:1280 for each strip. In parallel with this, antibodies to T. pallidum were assessed in the precipitation microtest. EIA proved to be not only highly specific, but more sensitive than precipitation microtest. Antibodies to T. pallidum are detected by EIA in serum dilutions at least two times higher than the minimal titers in the precipitation test. Thus, the above diagnostic kit is recommended for screening of donors of blood and its components.

[Diagnostic and prognostic value of interleukin-6 in malignant non-Hodgkin's lymphomas].

Sixty six patients with non-Hodgkin's lymphomas (NHL) were studied, interleukin-6 (IL-6) was revealed in the blood sera of 33 patients. IL-6 was revealed more frequently in patients with high-grade malignant (p < 0.05) than in those with low-grade malignancy. The largest group of IL-6 positive patients included NHL patients with diffuse large B-cell lymphoma and angioimmunoblastic lymphoma. The marked relationship was found between the serum IL-6 levels and the stage of disease: the serum IL-6 level was significantly lower in untreated patients with Stages II and III disease than in those with end-stage (IV) NHL. IL-6 significantly decreased upon remission, comparable with its level before the initiation of treatment. Analysing the association of prognosis of disease with the serum IL-6 showed that in the group of patients with good (The SNLG index < 2) and intermediate (2 < SNLG index < by 2.6) prognosis, the concentration of this cytokine was significantly lower than in those with poor prognosis (SNLG index > 2.6). There was a significant decrease of the total survival rates of NHL with serum IL-6 found. Therefore, IL-6 is a good prognostic marker in NHL and associated with the activity of a malignant process. Additionally, the increased serum IL-6 levels correlated with NK activities positively and with serum IL-4 levels negatively.

[The Epstein-Barr virus in patients with infectious endocarditis].

Serological markers of Epstein-Barr virus (EBV) infection has been investigated in 28 patients with infectious endocarditis. In 75% of patients IgM antibodies to "early" antigen of the virus which are the marker of active viral infection occurred vs 6.2% among healthy blood donors. Specific for infectious endocarditis reaction profile (anti-EBV combination in one person) indicates reactivation of latent viral infection. The conclusion is made on the necessity of further investigation of both the role of EBV in pathogenesis of pyoseptic diseases and immunologic mechanisms for reactivation of latent viral infections.

[Current problems in organizing the donor system in the Armed Forces].

In the work the factors, rendering essential influence on organization of donorship in modern army conditions are systematized. The organization of donorship should be connected to functioning of territorial system of medical maintenance of the Armed Forces of RF. It assumes presence of four organizational levels: central, district, zone and garrison. Perfecting the system of organization of donorship, we should be guided by the following conducting principles: maximum maintenance of safety of donorship; wide introduction of a method of plasmacytopheresis in work of establishments and subdivisions of blood supply service; organization of autodonorship and quota of the donors of an emergency reserve in each military-medical establishment; reliable maintenance of revealing of markers of hemotransmissible infections at inspection of the donors.
