一氧化氮与高原暗适应

RELATIONSHIP BETWEEN NITRIC OXIDE(NO) AND DARK VISUAL AT HIGH ALTITUDE

目的 :探讨吸入低浓度一氧化氮后对高原暗适应的效应 ,为急性高原病的防治积累参考资料 ;方法 :现场采用暗房夜光表检测法 ,对驻守在海拔 5 3 80m 6个月的 46名健康官兵进行了低浓度NO吸入 3 0分钟前后的暗适应检测 ;结果 :吸入低浓度NO后暗适应时间较吸入前显著缩短 (P <0 .0 1 ) ;结论 :在慢性缺氧的条件下 ,吸入低浓度的NO对大脑皮层功能及视网膜感光功能有明显的改善作用。

Objective:To explore the effects of low level of NO on dark visual in soldiers at high altitude.Methods:Test of dark visual was preformed in 46 healthy soldiers,who exposed to high altiutde( 5 380m ),before and after inspiring low NO 30 minutes.Results:After inspiring NO the time of adaptation in dark visual was shorter than before that (P<0.01).Conclusion:The dark visual function can be improved by inspiring low level of NO at high altitude.
