上呼吸道在尘肺的发病机制中有着重要的作用。尘肺形成期限以及所产生的损害在很大程度上取决于上呼吸道的状态。因此,作者对268例尘肺进行了观察和治疗(综合性物理及药物方法),其中160例确定为上呼吸道有病变。查明108例有某种程度的功能障碍,诊断为慢性卡他性鼻炎的55例,肥厚性鼻炎28例,轻度萎缩性鼻炎41例,鼻中隔偏曲24例。鼻粘膜卡他性病变时分泌功能变化最大,其中40%分泌功能增强。肥大性病变 The upper respiratory tract plays an important role in the pathogenesis of pneumoconiosis. The duration of pneumoconiosis and the resulting damage depend heavily on the state of the upper respiratory tract. Therefore, the authors observed and treated 268 cases of pneumoconiosis (comprehensive physical and pharmacological methods), of which 160 were identified as having upper respiratory tract lesions. Fifty-eight cases with chronic catarrhal rhinitis, 28 cases with hypertrophic rhinitis, 41 cases with mild atrophic rhinitis and 24 cases with nasal septum deviation were identified in 108 cases with some degree of dysfunction. Nasal mucocutaneous catarrhal lesions most changes in secretory function, of which 40% secretion enhanced. Hypertrophic lesions
