[Dynamics of changes in the composition of leukocyte population of peripheral blood during the African swine fever].

The comparison of the composition of leukocytes of peripheral blood of healthy and Infected swine revealed the quantitative alterations, as well as the appearance of new cells in leukocyte population during African swine fever. It was determined that African swine fever virus induced mass-scale mortality of cells of peripheral blood, especially lymphocytes and neutrophiles. The number of the dead cells reaches 60% of the initial number of all cells at the end of infection.

[Pathology of lymphoid tissue cells infected by African swine fever virus in vitro].

The authors studied the pathology of bone marrow (BM) lymphoid cell from pigs infected by African swine fever virus (ASFV) in vitro. Monocytes were shown to be primarily afflicted in unstimulated BM culture. These cells disappeared completely 72 hours after infection.

[Radiation protective effects of laser irradiation with wavelength 532 nm].

The combined effect of 532 nm laser radiation and alpha-particles on survival of Escherichia coli (AB 1157) has been investigated. The sensitivity of cells to alpha-particles was decreased by pre- and post-irradiation with laser.

[Cytological diagnosis and differentiation of tracheobronchial cylindromas].

From study of histocytological parallels in 12 cases of cylindromas the authors determined the criteria of cytologic diagnosis which allowed these tumors to be differentiated from other neoplasms of the lungs. Cylindromas are characterized by the presence in the cytogram of 2 types of cells (small cells and larger ones with light nuclei), homogeneous spherical structures with cells occurring centrally or on the periphery, ball-shaped clusters of cells, and an oxyphilic structureless mass forming the background of the preparation. The absence of oxyphilic masses in solid cylindroma, atypism and polyphormism of the epithelial cells makes it very difficult to differentiate it from moderately and poorly differentiated glandular carcinoma.

[The cytomorphological diagnosis of benign tumors of the peripheral nervous system].

Results of cytologic examination of punctates, imprints and scrapings as well as histologic sections of benign tumors of peripheral nerves surgically removed from 95 patients were used to study peculiarities of cytologic appearance and develop criteria for cytologic identification of the nature and histogenesis of those tumors. The analysis outlined the role of cytologic examination of punctates in complex preoperative diagnosis of peripheral nerve tumors. The procedure established the benign nature of tumor in 75.
