摘要: The concentration of nitric oxide (NO) is increased in the exhaled air asthmatic patients and may reflect cytokine-mediated inflammation airways. We investigated whether allergen-induced causes an elevation level NO. Of 25 who underwent allergen challenge, 16 developed dual early late responses, whereas eight had a single response. In with response, maximal fall FEV1 during response was 26.8 +/- 4.2% at 9 h there significant increase NO (maximal 59.4 9.8%) 10 after challenge. There relationship between size (r = 0.75, p < 0.01). have no NO, exception time point 21 h. five given control challenge methacholine change increase...
