测定３５例哮喘急性发作患儿血清一氧化氮代谢产物亚硝酸盐／硝酸盐水平。结果显示：哮喘急性发作患儿血清一氧化氮代谢产物水平明显高于正常对照（ｔ＝２．６５，Ｐ＜０．０５）。认为：一氧化氮参与了儿童哮喘的发病，测定其血清水平是判断儿童哮喘急性发作重要的实验室依据。
Serum nitric oxide metabolites nitrite / nitrate levels were measured in 35 children with acute asthma attacks. The results showed that serum levels of nitric oxide metabolites in children with acute asthma were significantly higher than those in normal controls (t = 2.65, P <0.05). That: nitric oxide involved in the pathogenesis of asthma in children, the determination of serum levels is to determine the acute asthma attack in children an important laboratory basis.
