Data are presented as mean +/- SD; SAR: patients with sarcoidosis, IPF: patients with idiopathic pulmonary fibrosis, COB: patients with chronic obstructive bronchitis, N: number of subjects, parameters of the two-term exponential relaxation model: Ar_s: fraction of slow decay, Tr_f: time constant of fast decay, Tr_s: time constant of slow decay, Tr_a: time constant of initial decay; b1: normalized decay after 1 min.; b5: normalized decay after 5 min.; Er: cell energy; ns: not significant; *: p < 0.05, **: p < 0.01). | ||||
