FEV1/FVC: ratio of forced expiratory volume in one second to forced vital capacity; BUD: nuclear buds; KR: karyorrhectic cells; KL: karyolytic cells; DI: damage index; MMS: methyl methanesulphonate; % residual damage, calculated for DI after 3 h MMS treatment for each subject taking the value of DI after 1 h MMS treatment as 100%.
