Abstract:
OBJECTIVETo obtain the normal values of nitric oxide (NO) exhaled through nose and mouth in healthy Chinese adults by measuring exhaled NO and analyzing the influencing factors.
METHODSEighty healthy Chinese adults were recruited, including 20 males and 60 females. The age ranged from 18 to 44 years old. Chemiluminescence analyzer (NIOX) was used to obtain the values of exhaled NO through nose and mouth. The relativity between NO and gender, age, height, body mass index, time, ambient NO were analyzed with Multiple linear regression and correlation.
RESULTSExhaled NO values were (17+/-8)x10(-9) and correlated significantly with height. Regression equation: Y (exhaled nitric oxide)=-58.524+0.457X (height, cm), t=-2.985, P<0.01. Transnasal NO values were (819+/-211)x10(-9) and correlated significantly with age and gender. Regression equation: Y (nasal nitric oxide)=760.245+9.417X1(age)-111.222X2(gender), t=5.188, P<0.01.
CONCLUSIONSExhaled NO normal values were 17x10(-9) and Transnasal NO normal values were 819x10(-9). Exhaled NO correlated positively with height. Transnasal NO correlated positively with age and negatively with gender.
