A total of 3475 subjects, engaged in such production for 2-20 years, were annually and before starting work examined by clinical and x-ray methods; 2427 of these were regularly exposed to ethylene oxide (the main group). X-Ray examinations included roentgenomorphologic (total fluorogram of the thoracic cavity organs and long-distance roentgenograms, tomograms, bronchograms, if necessary) and roentgenofunctional (roentgenopneumopolygraphy) methods of examination of the bronchopulmonary system. Chronic bronchitis was detected in 407 workers of the main group and in 79 controls; in 76.

The results of fluorographic, roentgenoscopic and roentgenographic investigations of the lungs, roentgeno-pneumopolygraphy and radionuclide investigation of lung perfusion (pulmoscintigraphy with 99mTc-labeled albumin macroaggregates) were compared. During this combined investigation the signs of nonspecific pulmonary diseases were diagnosed in 40% of the patients, changes of the pulmonary blood flow--in 71%, changes in ventilation--in all the examinees.

The results of a combined roentgenoradionuclide investigation of the lungs were studied in 45 persons at risk of developing chronic nonspecific pulmonary diseases, diagnosed in a mass screening of 3000 workers at an industrial enterprise. The results of fluorographic, roentgenoscopic and roentgenographic investigations of the lungs, roentgenopneumopolygraphy and radionuclide investigation of lung perfusion (pulmoscintigraphy with 99mTc-labeled albumin macroaggregates) were compared.

The dynamic morphofunctional X-ray examination along with a study of external respiratory function made it possible to study the pattern of functional disturbances in patients with tuberculosis of respiratory organs and concurrent bronchial obstruction. Roentgeno-pneumopolygraphy supplemented with physical exercise tests and berotec specified the localization, extent and the character of disorders of bronchial patency and enabled one to study the compensatory mechanisms of external respiratory function during antibacterial therapy.
