Procedure: Induced sputum (inhalation of 3.5% saline)
Twenty Ulcerative colitis patients and 20 control subjects (all nonsmokers) without respiratory symptoms will be tested. The induce sputum by 20' inhalation of 3.5% saline using ultrasonic nebulizer. Samples will studied by differential counts of 200 cells on cytopreps stained by Giemsa. T-lymphocyte subset analyses were done by FACS using three monoclonal antibodies: CD3 = total T cells, CD4 = T helper cells, and CD8 = T suppressor-cytotoxic cells. CD4/CD8 >2.5 was considered abnormal.
