大气污染使支气管哮喘发病率增加,然而SO_2,NO、NO_2、O_3等本身非抗原物质。本文用动物实验研究NO或NO_2加上白蛋白附加暴露时对呼吸的影响。使用雄性200克左右的豚鼠随机分成三组:NO或NO_2暴露组和对照组,每组12只豚鼠。NO来自液态NO加热至35℃使成气体,用氮气稀释。NO和NO_2平均浓度分别为5.02ppm(4.40～5.65ppm)和5.00(4.20～6.20)ppm。白蛋白喷雾液为
Air pollution increases the incidence of bronchial asthma, however, SO2, NO, NO2, O3 itself non-antigenic material. In this paper, animal experiments were conducted to study the effects of NO or NO 2 plus resorption on albumin exposure. Guinea pigs of about 200 g male were randomly divided into three groups: NO or NO 2 exposure group and control group, 12 guinea pigs in each group. NO from liquid NO heated to 35 ° C into a gas, diluted with nitrogen. The average concentrations of NO and NO 2 were 5.02ppm (4.40 ~ 5.65ppm) and 5.00 (4.20 ~ 6.20) ppm, respectively. Albumin spray solution is
