Objective:To determination of the smoking effect on some immunity parameters and compare the results with the non-smokers by using IFN-γ, CD4+and CD8+.

Patients and Methods: 45 of smokers blood samples and 44 of non-smokers blood samples are collected. The levels of cellular of IFN-γ,CD4+and CD8+has been determined by using sandwich ELISA test.

Results: The study included 45 smoker that have the average age of 29.60 ( ± ) 10.36 year, while the healthy non-smokers group have 44 person who's have the average age of 26.56 ( ± ) 9.09 years old. When comparing the level of CD4+T cells ,CD8+T and the level of IFN-γwith the number of cigarettes consumed per day, the class (20-1) was found to be the highest average of T cells.while (40-21) were less than average, with no significant difference. When comparing the level of CD4+T cells and the level of CD8+T cells with IFN-γwith smoking duration, the highest mean T-cell (10-6) years and the lowest mean (25-21). The results of the present study showed a statistically significant association between CD4+, CD8+and IFN-γmolecules.

Conclusion: The general results of the tests on the effect of smoking on immunologic markers CD4+, CD8+and IFN-γassumed an increase in the ratio of the three indicators compared to the control group.
