Recently some reports say that nitric oxide (NO) increased in exhaled air of asthmatic children. We measured NO concentration of asthmatic children and control subjects.
The result was that NO was significantly higher in exhaled air of asthmatic children than control subjects. There was no significant difference between asthmatic children who had athmatic attacks within 1 month and those who did not. But the children who suffered attacks within 2 weeks showed higher NO concentration than those who did not.
We assume that measurement of NO concentration in exhaled air is efficient on judgement of asthmatic state.
