[Fine structure studies in the lungs of infants with idiopathic respiratory distress syndrome].

Authors studied ultrathin cestions of lung of ten newborns died of IRDS in the various stage of the disease. It was established that lamellar bodies are already formed in the initial phase of the disease. In the first two clinical phases by pneumocytes type II structure of the intracytoplasmic and intaraalveolar lamellar bodies differs from the normal, and they can not form air-cell interphase. In the third clinical phase--in the phase of the resolution-mature lamellar bodies of normal structure are formed and get into the alveolar space, thus the condition of formation of air-cell interphase is given.
