The action of high doses of cigarette smoke alone or combined with coal dust or acrolein was investigated in noninbred Sprague-Dawley rats. Inhalation occurred up to six sessions per day (Hamburg machine), the animals being subjected to a treatment w

To evaluate the potential risk of pulmonary damage due to aerial spraying of the insecticide fenitrothion, rat lungs were examined under light and electron microscopy at 3, 7, 21, and 60 days after exposure. Rats were exposed by a “nose-only” app

The analysis of dust deposits by means of an illuminated slit allows simultaneous counting and size distribution analysis. For counting, it is possible to provide statistical compensation of errors due to fractional interception, overlapping, coincid

The toxic effect of two forms of sand on the lung was investigated by tracheal injection in Rats. After a latent period with low toxicity, more and more extensive pulmonary lesions, comparable to typical silicotic lesions, appear progressively. On th

The toxicity of various minerals (kaolin, muscovite, illite) was compared by tracheal tests on rats to that of reference dusts (quartz, titanium dioxide, coal). These minerals have various degrees of toxicity. Owing to their sometimes very high conce

Plane-tree pollen grains were incubated in vitro with alveolar macrophages from inbred Rats, and the possibility of phagocytosis was investigated. No phagocytosis was observed even after 48 hrs incubation. But alveolar cells were bound to pollen grai

Pulmonary toxicity by inhalation of two coal-mine dusts containing 15 and 5% quartz was compared with that of artificial coal-quartz mixtures having the same quartz content. The natural dust mixtures were slightly toxic, while the artificial ones pro
