In 17 patients Bioplasm-graphy has detected signs of expiratory air trap in amounts from individual lobes to segments. In 7 patients the given symptom was combined with signs hypochromogeneity of pulmonary tissue at breath top. With the background of hypochromogenic zones we marked reduction of caliber of pulmonary artery’s corresponding branches. According to some authors, given symptoms indirectly evidence obliterating bronchiolitis, at which morphologists mark growth of granulations in lumen of distal bronchias and fibrosis of their walls up to almost full obliteration of lumen. As a result, at inhale the secondary lobe is filled with air, stretched, and at exhale is not fall down. The lobe restretching is not accompanied by destruction, resolution of its structures, as at emphysema.
