Feb. 1953 Italian The author has investigated cases of warts on the hands of 29 workers with lagging materials including asbestos cord which is wound around pipes various containing slabs and mixtures of asbestos and cement to be molded to the shape of the tank or other object to be insulated One to four warts were found in every case They are due to asbestos fibers which penetrate into the epidermis and become lodged in the corium or true skin The epidermis shows acanthosis thickening of the prickle layer and hyperkeratosis increased horny tissue and the corium shows a granulo- matous type of reaction with the appearance of giant cells in some cases Exudative dermatitis may also be present This condition is attributed to the combined action of the hygroscopic and alkaline cement and the irritating asbestos fibers The gross and microscopic appearances of the lesions are illustrated -- Cond from Bull Hyg Dermatitis Due to Pancreas S.

Heffernan Tubercle 34 246-249 Sept. 1953 The author rejects the solubility theory of silicosis and propounds instead a surface valency theory The structure of freshly fractured silica is held to possess chemical surface activity with ability to coagulate and fix large masses of organic material The freshly fractured ends of asbestos are postulated to possess the same activity hence asbestosis Freshly powdered aluminum forms a protective coating over the silica particles to render them Harmless Further details are given but the discussion is entirely theoretical -- Cond from Bull Hyg 550 The Nature of Lesions Caused by Asbestos and Mica in Experimental Pneumoconiosis in Guinea Pigs A.

Dust J. F. Knox and J. Beattie Arch Ind Hyg & Occ Med 10 30-36 WIL July 1954 ' The particle distributions in the incombustible and insoluble residues from the lungs of 27 persons who had been exposed to asbestos dust were determined The number of particles with greatest lengths in excess of 26 microns was considerable up to the eighth year after the last exposure to asbestos dust and then sharply fell The number of particles within the size ranges of five microns and less and between five and 15 microns remained constant over a very long period in those cases which showed no sign of asbestosis or minimal fibrotic change The cases of severe asbestosis showed a significant rise in the numbers of such particles It is considered that the mechanism which is concerned with the production of human asbestosis is not the same as that which is responsible for the production of asbestotic changes in experimental animals exposed to high concentrations of asbes- tos dust The appearance of such changes seems to be related to the breakdown of asbestosis bodies which may liberate some fibrogenic agent . -- Authors summary 1 222 Mineral Content of the Lungs after Exposure to Asbestos Dust J.

The mineral content of the lung parenchyma the lung hilar region and the tissues of the pleural and subpleural regions of the lung has been determined in lungs from 27 workers in the asbestos industry The exposure time varied from five to 33 years and the time interval between the last exposure to dust and death survival time was from less than one year to 21 years There was an indica- tion that the mineral material found in the lungs increased in amount as the exposure time lengthened The amount so accumulated varied considerably from person to person As the survival time increased the mineral content of the lung tended to decline but again at a very variable rate in the lungs found at death was related not the exposure and survival times The severity of the asbestotic lesions to the mineral content but to the sum of - Authors summary | in 1k : |.
