The negatives were embroidered using a mouse IgG1 antique MOPC body cell line as a prime Rer antique Body. The treatment of bronchial epithelial cells with cilomilast bronchial epithelial cells were in the absence or presence of 1 ? ?M cilomilast cultured for 24 hours at 37 in a humidified 5 CO2. This cilomilast was determined in each of three consecutive dose-response curves in which the effects were evaluated for the release of TNF ? ?? ? ?? th GM-CSF three concentrations of cilomilast.
At the end of the incubation period, the Lebensf Assessed ability of the cells by 90 as trypan blue exclusion and cell-Cured Walls were harvested. At 80 for a more detailed analysis and chemotaxis assay Sputum induction and induction of sputum conversion and processing are gem found the method of Hargreaves et al modification.21 performed without differential cell counts on cytocentrifuge preparations with May Grunwald Giemsa conducted rbt. In all F Cases 400 cells were hlt by two observers blind gez And the results are expressed as percentage of the total cells. Treatment of the cells with cells from sputum sputum cilomilast were resuspended at a concentration of 1 ? ? 06 in RPMI 1640 10 ml heat-inactivated FCS a penicillin-streptomycin, L L solution of 1 mmol L glutamine.
The cells were in the absence or presence of sputum cilomilast ? ?M for 24 hours at 37 in a humidified 5 CO2 cultured. This cilomilast concentration was determined evaluated on the basis of three consecutive dose-response curves in which the effects of three concentrations of the drug were on the release of TNF ? ?? ? ?? th GM-CSF. Dose-response experiments with the curve of a gr Eren number of points of the concentration were prevented by the limited number of cells. At the end of the incubation period, the Lebensf Ability of the cells 85, as assessed by trypan blue exclusion, and the Cured Walls were harvested. At 80 for further analysis and chemotaxis assay Measurement of TNF ? IL-8 and GM-CSF absolute values of TNF ?

TNF ? IL-8 and GM-CSF kits were purchased from R & D Systems, and their detection limits were 0.18 pg ml, 3 pg ml and 10 pg ml neutrophil chemotaxis assay to additionally USEFUL support for the hypothesis that cilomilast can play an r Decreased in the migration of neutrophils in the airways of COPD patients, we give the F Capacity of up Cured Walls investigated by bronchial epithelial cells and sputum cells in the presence or absence of cilomilast ? ?M incubated for 24 hours at 37 in the CO2 in humidified 5 induce neutrophil chemotaxis.
