The results are reported from the radioisotope investigations of the regional blood supply, ventilation and difussion of 133 Xenon from four zones of both lungs in 78 patients with all stages of silicosis and 43 patients with chronic bronchitis--emphysema. Unsystemic and scattered focal disturbances of the separate respiration processes are established. They should be given consideration separately and together with the classical non-isotope investigations, with a view to the making of a precise functional diagnosis and occupational expertise, because they reflect the changes due to the basic disease as well as the other accompanying lung diseases as pneumosclerosis, chronic bronchitis, emphysema, tumors, etc. The complete safety, lack of unpleasant procedures for the patient and sufficient accuracy urge their wider application in practice, including as screening tests.

Left lung homotransplantation was performed in a 31-year-old man in terminal irreversible respiratory failure due to advanced silicosis. Within 10 minutes of completion of transplantation, arterial pO(2) rose from 52 to 211 mm. Hg, pCO(2) dropped from 90 to 43 mm. Hg, and pH rose from 7.15 to 7.42. On assisted ventilation, arterial O(2) tension was maintained within normal limits for the first four days. Thereafter, arterio-alveolar difference for O(2) increased to 300 mm. and that for CO(2) to 25 mm. Xenon-133 ventilation perfusion ratios confirmed differences between the two lungs. Terminally, bronchopneumonia and hypoxemia were present. Surfactant content of the lung was within normal limits. Postmortem examination revealed bronchopneumonia, bronchial infarction, lymphatic engorgement and mild rejection. Future efforts should emphasize selection of non-infected donors, minimal reliance on steroids for immunosuppression, cardiopulmonary bypass during transplantation, and more definite criteria for rejection.
