Free radicals, as a product of cigarette smoke, are considered to have deleterious effects causing oxidative stress. Acute active smoking seems to be followed by transient leukocytosis and delayed increase in neutrophil activation. The aim of the present study was to investigate the oxidative status of smokers and passive non-smokers, as well as the impact that acute cigarette smoking has on hematological parameters. ⋯ Acute exposure to cigarette smoking affects hematological indexes and oxidative stress biomarkers negatively, in both active and passive smokers, with similar results. The outcome seems to be even worse in passive smokers regarding oxidative stress and antioxidant protection markers. Elimination of cigarette smoking could prevent the adverse effects for smokers, as well as for healthy non-smokers in their vicinity. Hippokratia 2015; 19 (4): 293-297.

Recent studies provide evidence that peripheral blood monocytes have the ability to differentiate into mesenchymal-like cells. The ability of cultured monocytes to differentiate and produce insulin in vitro is analysed in the present study. ⋯ Monocytes can acquire morphological properties of multipotent cells when they are cultivated under specific conditions in vitro. Differentiated monocytes are able to synthesize and excrete insulin. Hippokratia 2015; 19 (4): 344-351.
