A new method for the study of lining-layer and pulmonary alveolar walls with electron microscope.
The authors describe an original method for the setting up of pulmonary parenchymal preparations to be observed with electron microscopy. The salient aspects of this method are: the material fixed with a supersaturated uranyl acetate solution and colored, after simple dehydration and inclusion in Epon 812, with bismuth subnitrate. With this method it is possible to obtain a good definition of the morphological aspects and a greater contrast of the phospholipidic structures of the pulmonary parenchyma.
