RESUMEN
External respiratory function was examined in 27 patients aged 5 to 17 years suffering from alveolitis. Of these, 10 children were diagnosed to have idiopathic fibrosing alveolitis and 17 exogenous allergic alveolitis. The functional examination included investigation of the static pulmonary volumes by helium dilution method, spirography, body plethysmography, measurements of lung elasticity, diffusion capacity of the lungs and blood gases. It has been established that in alveolitis, restrictive ventilatory disorders prevail, whereas in acute and subacute exogenous allergic alveolitis, obstructive disorders may occur. In all the patients examined, lung diffusion capacity was found to be reduced.

During a remission, bronchial asthma children were examined for bronchial hyperreactivity and bronchial lability by means of graded physical exercise tests, and pharmacological tests with bronchoconstrictors and bronchodilators. It has been established that normal lung function seen during aa remission does not mean the lack of bronchial hyperreactivity whereas incomplete recovery of bronchial patency during bronchial asthma remission is always attended by bronchial hyperreactivity in almost all the cases. In carrying out functional tests for bronchial hyperreactivity and bronchial lability, the recording of the velocity parameters of forced expiration making it possible to define patency of not only the central but also of the peripheral bronchi appeared very informative.
