Biological effects of cigarette smoking assessed with the NBT test.
The NBT reduction spontaneous and stimulated test was carried out on 90 men; 30 of which had never smoked cigarettes, 28 subjects have smoked for up to 10 years and 32 subjects--since over 10 years. The investigations demonstrated show that in subjects smoking cigarettes for up to 10 years the spontaneous and stimulated ability of the neutrophils to reduce NBT was increased whereas in the subjects smoking cigarettes since over 10 years impairment of the stimulated NBT reduction was demonstrated. We've come to a conclusion that an exposure to tobacco smoke may activate oxidation-reduction processes of the neutrophils in the initial stage and impair them in longer stage of smoking.
