[The relationship between bronchial hypersensitivity and the prognosis of bronchial asthma].

I measured RT-Ach, RT-Hist and EIA of asthmatic children every year and studied the relationship between these three parameters and their prognoses. I obtained the following results. 1) If the patient's RT-Ach and EIA improved in three years, I could say that his clinical symptoms had improved and his prognosis was good. RT-Hist results, however, would be unchanged even if clinical symptoms improved. 2) In asthmatic children, EIA is important for short term prognoses while RT-Hist is important for long term prognoses.
