[Several aspects of clinical signs and pathogenesis of pneumopathies in acute poisoning caused by sulfur-containing natural gas].

The article summarizes and analyzes data on 32 cases of acute intoxication varying in severity and caused by inhalation of sulfur-containing natural gas of Astrakhan gas deposit (SCNGAGD). The data were obtained in experimental poisoning of 120 Wistar rats with the gas. Pneumopathies (toxic pulmonary edema, pneumonitis, asthmatic bronchitis, alveolitis) appeared to play the central role among other syndromes of the intoxication by SCNGAGD. Mechanisms of the pneumopathies were traced to morphologic disorders of blood-lung barrier, compromised functions of lung surfactant, disturbances in lipid peroxidation and anaerobic glycolysis.
