[Possible pleurogenic route in the development of bronchiectasis in children].
Chronic pneumonia with bronchiectases develops often after acute destructive pneumonia with pleurogenous complications. This process is attributed to infection of the pleural adhesions, disorders of pleuropulmonary circulation of blood and lymph, and changes of the rhythmic activity of the bronchi. Study of the motor activity of the smooth-muscle structures of the wall of bronchi involved in a chronic process disclosed sharply diminished tonus and activity of biopotentials. In the initial forms of chronic unspecific pulmonary diseases affection of the neuromuscular apparatus responsible for conduction of the nerve impulse occurred, then the muscle fibres became involved in a sclerotic process, which was attended by reduced evacuation function of the bronchi. The reduction of the bronchial motor function closes the vicious circle of disorders of the pleuropulmonary connections of blood and lymph circulation and is conducive to rapid progress of the chronic process in the lungs.
