众所周知,棉和黄麻粉尘接触可引起可逆性气道阻塞。作者比较了50名接尘工人与99名非接尘工人的呼吸道症状的发生率以及通气功能损害,还有五个工作日后与吸入Salbutamol后肺功能的变化。两组间,呼吸道症状的发生率无显著性差异;星期一早上肺功能无差异,而星期五下午有显著性差 It is well-known that cotton and jute dust contact can cause reversible airway obstruction. The authors compared the incidence of respiratory symptoms and ventilatory impairment in 50 exposed workers and 99 non-exposed workers, as well as changes in lung function after inhalation of Salbutamol after five working days. There was no significant difference in the incidence of respiratory symptoms between the two groups; there was no difference in lung function on Monday morning and a significant difference on Friday afternoon
