Abstract
산화질소(Nitric Oxide, NO)는 인간의 상기도에서 아주 중요한 매개체이며 염증 표지자로 부비동과 비강 점막에서 생성되며, NO의 생성에 관여하는 효소는 국내에서도 많이 연구되었으나 Nasal nitric oxide(nNO) 직접적인 분석은 국내에서 이루어진 적이 없고, 최근에 국제적으로 많이 연구되기 시작하였다. 이에 국내에서는 한번도 이루어지지 않은 nNO 측정법을 소개하고, 정상인에서 nNO, eNO(exhaled NO)를 측정하여 한국인에서 그 정상치를 추정해 보고, 이를 상기도 염증성 질환에서 어떤 차이가 있는지 알아보고자 한다.nNO는 화학 발광 분석기를 이용하여 측정하였고 700ml/min의 속도로 양측 비강에서 각각 2회 흡입하여 평균으로 하였다. 정상인 32명, 알레르기 비염 환자 31명, 비용종을 동반한 비부비동염 환자 30명을 대상으로 nNO를 측정하여 비교해 보았다.1.정상 대조군에서 nNO의 평균 농도는 241±89 ppb로 측정되었고, eNO는 20.5±6.4 ppb로 측정되었다.2.알레르기 비염군에서 nNO는 평균 332±125 ppb로 측정되었으며, 정상 대조군과 비교하여 통계적으로 유의한 증가를 보였다(p=0.002). eNO는 26.9±10.1 ppb로 측정되었고, 정상 대조군에 비해 통계적으로 유의한 증가를 보였다(p=0.004).3.비부비동염 군에서는 nNO가 89±55 ppb으로 측정되어 정상 대조군에 비해 통계적으로 유의하게 낮은 결과를 보였다Background and Objectives Nitric oxide (NO) is present in high concentrations in the upper respiratory tract. The physiological role of this mediator is to contribute to the local host’s defense, modulate ciliary motility and serve as an aerocrine mediator in helping to maintain adequate ventilation-perfusion matching in the lung.Subjects and Method The purpose of the study was to assess the relationship of nasal NO (nNO) and exhaled NO (eNO) in nasal airway disease patients. NO concentration was measured using a chemiluminescence analyzer. nNO was analyzed by aspiration at a sampling flow rate of 700 mL/min with velum closure. eNO was analyzed during expiration against a constant resistance of 10 cm H2O.Results NO concentration of the normal control group (n=32) was compared with that of the allergic rhinitis group (n=31) and the rhinosinusitis with that of the nasal polyp group (n= 30). The mean nNO level in the control group was 241±89 ppb and eNO was 20.5±6.4 ppb. The mean nNO level was significantly increased in the allergic rhinitis group (332±125 ppb) but decreased in the chronic sinusitis group (89±55 ppb). The mean eNO level was significantly increased both in the allergic rhinitis group (26.9±10.1 ppb) and chronic sinusitis group (29.8±12.8 ppb).Conclusion nNO concentration was increased in patients with allergic rhinitis and decreased in patients with chronic sinusitis; however, eNO was increased in both patients. This shows that patients with upper respiratory inflammation may also have lower respiratory inflammation, supporting the concept of ‘one airway, one disease’. This study shows that measurement of NO is useful for the study or evaluation of nasal diseases.
