[The state of the "glycocalyx" of rat lung cells following left-sided pneumonectomy].
Edema in the tissue of the right lung developed 24 hours after the leftsided pneumonectomy. It was found that: 1) the layer of acid mucopolysaccharide on the surface of the alveolar and endothelial cells became thicker; 2) accumulation of the product of reaction with the RR on the surface of the alveolar cells of type 1 and of the endothelial cells took place; 3) "blisters" coated with the product of reaction with the RR (Red Ruthenium) appeared. These "blisters" were connected with the plasmolemma of the alveolar and endothelial cells. All these findings suggest that acid mucopolysaccharides of the lung surfactant system participated in the accumulation and elimination of the water from the tissues of the air-blood barrier.
