X-Ray Observations on Experimental Respiratory Distress Syndrome in Dogs / 第三军医大学学报

Oleic acid was injected intravenously into 29 dogs to induce the experimental 'Respiratory Distress Syndrome'. The chest x-ray manifestations of RDS were observed and analyzed. Correlating the x-ray findings with the findings of patho-anatomical examination, which was done on the killed dogs, the authors tried to investigate the pathogenesis of RDS. Meanwhile the diameter of the first branch of either inferior pulmonary artery was measured to determine the variations of the contractions of the pulmonary arteries.Finally the therapeutic effect of anisodamine and dexamethasone was compared. It seemed that the effect of the former was better than that of the latter from our preliminary trial.
