42-47. Between 1966 and 1968, 2 316 operatives were examined in the blow and card rooms of the south-east Lancashire coarse cotton industry. Between 1968 and 1970, a second survey of 2 556 operatives was carried out including 886 of the previous group and also operatives in fine and coarse cardrooms, in ring and winding rooms, and operatives in other parts of the country who were not examined previously. Symptoms and ventilatory changes of byssinosis were found in operatives in all mills except the two fine cotton mills. Some operatives with less than 10 years' exposure were classified as byssinotic, including 14 in the first survey and 17 in the second who had had less than five years' exposure. These operatives were found in all types of work room. The 886 operatives examined on two occasions showed a greater deterioration in ventilatory function than a local control population. Even symptom-free operatives showed a 10% excess in the rate of deterioration of FEV with age. But neither the ventilatory tests nor the symptomatic enquiry were of value in predicting the rate of deterioration between the two studies.
42 - 47. 1966年至1968年间，对兰开夏郡东南部粗棉纺织业的清棉车间和梳棉车间的2316名工人进行了检查。1968年至1970年间，对2556名工人进行了第二次调查，其中包括前一组中的886人，以及精梳和粗梳车间、环锭纺和络筒车间的工人，还有该国其他地区之前未接受检查的工人。除了两家精纺棉厂外，在所有工厂的工人中都发现了棉尘病的症状和通气功能变化。一些接触时间不到10年的工人被归类为棉尘病患者，其中第一次调查中有14人，第二次调查中有17人接触时间不到5年。这些工人分布在所有类型的车间。接受两次检查的886名工人的通气功能恶化程度比当地对照人群更大。即使是无症状的工人，其第一秒用力呼气量（FEV）随年龄增长的恶化率也高出10%。但是，无论是通气功能测试还是症状询问，在预测两项研究之间的恶化率方面都没有价值。
