Baikal Lake fish: stone sculpin (Paracottus knerii), yellowfin (Cottocomephorus grewigkii) and perch (Perca fluviatilis) were exposed for 14 days to phenol (6mg˖L-1). The reaction of blood cells in all studied species had a similar character, whilst, also revealing distinctions. Fast activation of immune processes was found in the pelagic yellowfin. These changes were slower at the coastal stone sculpin. Quantitative changes of blood cells were minor in the coastal nonendemic perch. After four days of exposure, the cells of fish showed signs of destructive processes: strong vacuolization of cytoplasm and partial destruction of the cell membrane. In the cell nucleus the chromatin was condensed, the perinuclear space had expanded and the nuclear membrane had been partly destroyed. In another experiment, stone sculpin and perch were first exposed to phenol for 30 days and then they were kept for another 30 days in water without phenol. In the kidneys and spleen of stone sculpin the processes of lymphopoiesis were observed, whereas in perch the processes of lymphopoiesis and myelopoiesis occurred.

W pracy przedstawiono wyniki badań nad wpływem niskociśnieniowej zimnej plazmy na biologiczną aktywność immunocytów. Analizowano zmiany fluorescencji limfocytów krwi ludzkiej. Wykazano wpływ zimnej plazmy na zmiany fluorescencji limfocytów, przy czym wzrost natężenia fluorescencji był wyższy w przypadku limfocytów osoby chorej niż zdrowej.

The effect of low-pressure cold plasma on biological activity of immunocytes was examined. The fluorescence of lymphocytes of healthy and ill person was examined. The increase of fluorescence intensity was observed in the lymphocytes of ill person.
