[The erythrocyte composition of the peripheral blood in tobacco smokers]

Data of cytometry and acid erythrography were evaluated in 60 tobacco smokers and 30 non-smoking healthy persons depending on length of smoking. Tobacco smoking was found to effect blood erythrocytes. Five-year smoking resulted in an increase of macrocytes, young resistant cells. Toxic signs were less pronounced concerning the resistance of circulating red cells. 6-10 years duration of smoking resulted in toxic lesions of the circulating erythrocytes confirmed by an increase of the number of spherulation-altered and low-resistant cells, early onset and late termination of hemolysis, increase of the percent of perished cells.
