The Cochrane Library, I. Taking in mind that composition and function of the natural lung surfactant differ among vertebrates pulmomar on the pulmonary anatomy and respiratory physiology and that its quality varies with the composicino of the animals, in the present work a biochemical and biophysical characterization of a pig lung surfactant from young and adult animals was studied in order to evaluate the quality of these surfactants.
