Abstract:
Preliminary studies to evaluate lymphocyte subsets bronchoalveolar lavage (BAL) and blood were carried out in a group of patients with lung asbestosis. The assessments were made by an indirect immunofluorescent method using monoclonal antibodies as a marker. The results were recorded on a flow cytofluorometer FASC-can. As compared with a control group, the patients with lung asbestosis showed a slight decrease in the total level of T lymphocytes (CD3) in BAL, however with a clearly disturbed proportion between T-helper (CD4) and T-suppressor (CD8) lymphocytes, which led to a decreased CD4/CD8 ratio. The blood level of T lymphocytes and their subsets in these patients approximated that in the controls. Heavy smoking was also found to enhance disorders in their number and proportion. The assessment of B lymphocytes (by using polyclonal antihuman immunoglobulins (sIg/FITC) showed a significantly high level of these lymphocytes in BAL with simultaneously low levels in blood in the same patients with lung asbestosis. We did not find a clear synergic effect of cigarette smoking on the levels of B lymphocytes in the studied group.
