The cases were grouped by the complication of pulmonary tuberculosis and the type of ventilatory impairment.
FEV_(1.0) decreased 110㎖ in the group of normal type which complicated with pulmonary tuberculosis. In the group of pure coal workers´ pneumoconiosis, there were no significant change in each impairment type of FVC and FEV_(1.0). Suppose, it was due to small sample size in thses impairment types.
