متن کاملHistocompatibility antigens in coal miners with pneumoconiosis.
Twenty-five histocompatibility antigens have been measured in 100 coal miners with pneumoconiosis attending a pneumoconiosis medical panel and the results compared with a panel of 200 normal volunteers not exposed to dust. Chest radiographs were read independently by three readers according to the ILO U/C classification. On a combined score, 40 men were thought to have simple pneumoconiosis and...
متن کاملCoal miners' pneumoconiosis in four collieries in county Durham.
Clinical experience (Browne, Beck, and McCallum, 1949) and rising certification figures by the Pneumoconiosis Medical Board show that there is a pneumoconiosis problem amongst Durham coalminers. Moreover, a study of large films, taken following routine mass miniature radiography (M.M.R.) at eight Durham pits (McCallum, 1952), suggested that at least 3 to 6% of miners at these pits had well mark...
متن کاملBlood Groups of Miners with Coal-workers' Pneumoconiosis and Bronchitis.
An unexpected finding in a survey of a random sample of men from the Rhondda Fach valley in South Wales suggested an association between blood group A and coal-workers' pneumoconiosis. A further and larger sample of 1,250 miners and ex-miners from the same area, covering the same age range of 35 to 64 years, was chosen at random from the population in order to verify this finding. Each man was ...
متن کاملPneumoconiosis of coal-miners in three North-umbrian collieries.
Radiological pneumoconiosis is common amongst coal-miners in County Durham, and in four collieries about 22% of men at work above and below ground had fairly well-marked lung changes of category 2 or more (McCallum and Browne, 1955). There are no reliable prevalence data for pneumoconiosis of coal-miners in the adjacent coalfield of Northumberland, but its mines are thought to produce little pn...
