The questionnaire included questions regarding personal characteristics, dependence and quitting smoking, consequences on health. Lung function tests were performed in 31 students (16 smokers and 15 non-smokers). The serum concentrations of sICAM-1 and -3 were determined using ELISA-method.Results: There were 18,8% of current smokers (from which 46% females); an index of duration of smoking was 3,0±1,9 pack/years. The early age of the beginning of smoking (of 9-14 years) has been registered. Means of FVC and PEF in smoking students were significantly lower than in non-smoking (81,1±5,9 vs 87,5±9,1% and 75±9,7 vs 84,9+7,6%, respectively). The serum levels of sCD50 and sCD54 in smoker (140,4±57,7 U/l and 78,9±29,7U/l, respectively) were significantly reduced compared with non-smoker (242,4+54,4 U/l and 172,7+51,5 U/l, respectively).Conclusion: These results indicate high level of tobacco use among medical students in this Russian city, especially among females. The reduced levels of FVC and PEF, as well as of sICAM-1 and -3 in smoker compared with non-smoker were revealed. Decrease in levels of sCD50 and sCD54 in smokers might be due to inhibitory effect of smoking on intercellular adhesion. ER -
