Abstract
Holt, P. F. (1971). Brit. J. industr. Med., 28, 72-77. Poly(vinylpyridine oxides) in pneumoconiosis research. Schlipköter and Brockhaus of the Institut für Lufthygiene Düsseldorf found that poly(2-vinylpyridine 1-oxide) can inhibit the fibrosis normally produced by quartz dust in the lungs or other tissues of animals. Later research in Germany and elsewhere has confirmed the earlier observations. The polymer is active when the quartz is administered by intratracheal, intraperitoneal or intravenous injection or by inhalation. It is effective if given in aqueous solution by intraperitoneal or subcutaneous injection or if it is inhaled as an aerosol.
