title: [Utility of the ultrathin fiberscope for the diagnosis of chronic obstructive pulmonary disease].
abstract: The purpose of thin fiberscope examination for COPD are to investigate the relationship between structure and obstructive lung function and to realize the genetic mechanism by the specimen taken from the peripheral airways. The obstructive site of the airway is the 10th order bronchus and peripheral airways from this site are characterized by web like trabecula formation and granular deformation of the mucosa. The role of cytotoxic T cell is considered to be important for the formation of peripheral airway disorders.
