This study aimed to investigate the pulmonary effects of methylmethacrylate (MMA) in a group of occupationally exposed workers. In the exposed group 20% had chronic cough compared with 1% in controls. Spirometric values at the beginning of the workshift were similar in both groups, but a mild airways obstruction appeared during the workshift. The maximum expiratory flow when 50% of the forced vital capacity remained to be exhaled (MEF50) and the ratio of MEF50 to maximal expiratory flow (MEF50/MEF) decreased significantly during the workshift among exposed workers v controls (p = 0.04 and 0.01 respectively). Results remained unaffected after adjustment for smoking. Exposure to MMA seems to be responsible for a mild airways obstruction but further study on a larger population would be useful.
本研究旨在调查甲基丙烯酸甲酯(MMA)对一组职业暴露工人肺部的影响。暴露组中20%的人有慢性咳嗽,而对照组中这一比例为1%。两组在轮班前的肺功能测定值相似,但在轮班期间出现了轻度气道阻塞。暴露工人在轮班期间,呼出50%用力肺活量时的最大呼气流量(MEF50)以及MEF50与最大呼气流量之比(MEF50/MEF)与对照组相比显著降低(分别为p = 0.04和0.01)。在对吸烟进行校正后,结果不受影响。接触MMA似乎是导致轻度气道阻塞的原因,但对更大规模人群进行进一步研究将是有益的。
