Asbestosis

Peritoneal Tumours in Asbestosis.

Eleven cases of diffuse abdominal tumours in association with exposure to asbestos were discovered in the years 1958 to 1963. There were eight men and three women, all of whom had worked at the same factory. In seven of the men the age at death ranged from 38 to 78 years; one man is still alive at the age of 46. The women died at 44, 61, and 67. The survival time after the first exposure varied...

Pathological aspects of asbestosis.

WIDESPREAD recognition of asbestosis dates from the work of Merewether and Price in 1930. They investigated 363 asbestos workers and concluded that there was a pneumoconiosis resulting from asbestos inhalation, that this condition shortened life, and that measures to diminish the atmospheric concentration of asbestos dust would reduce the incidence of the disease. In 1931 asbestosis was accepte...

Asbestosis in experimental animals.

Previous animal experiments with asbestos dusts have been almost entirely confined to chrysotile asbestos. It was, therefore, decided to investigate the effects of mill dusts from the three types of asbestos that are produced commercially in South Africa, namely chrysotile, amosite, and crocidolite. Chrysotile and amosite samples were relatively pure while in contrast the crocidolite dust was f...
