本文对几家小型家俱厂从事木工的工人和一组健康非接触的人群进行调查。这些人群的特征如下:A组:健康的作业人员。B_1组: 作业工人有慢性咳嗽和运动性呼吸困难。B_2组:作业工人工作时有呼吸困难和支气管反应性增强。C组:随机挑选的非职业性的实验室人员。实验项目有:用木尘流浸膏做皮肤试验,血清学试验(测定C_3、C_4、IgG、IgM、IgA和IgE的浓度)和肺功能试验(测定FVC、FEV_1、MEF_(50)、TL_(CO)和K_(CO))。 B_2组对木尘流浸膏的皮肤反应阳性率与A组相比有显著性增高。修正后的FVC和FEV_1/FVC百分比值B_1组显著地低于其他组(B_1<
This article investigates workers engaged in woodworking and a group of healthy non-contact groups in several small furniture factories. The characteristics of these groups are as follows: Group A: Healthy workers. Group B_1: Workers have chronic cough and exercise-induced dyspnea. Group B_2: working workers have dyspnea and increased bronchial reactivity at work. Group C: randomly selected non-occupational laboratory personnel. The experimental items include skin test with wood dust extract, serological test (concentration of C_3, C_4, IgG, IgM, IgA and IgE) and pulmonary function test (FVC, FEV_1, MEF_50, TL_ CO) and K_ (CO)). The skin reaction positive rate of B_2 group to wood dust extract was significantly higher than that of group A. The corrected FVC and FEV_1 / FVC percentage values in B_1 group were significantly lower than those in other groups (B_1 <
