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

On the basis of three new cases of pulmonary fibrosis due to heavy metals, the authors review the various clinical, radiological and respiratory function test criteria which lead to the diagnosis of this type of occupational fibrosis. This is an unco

IL 1 can be released from P388D1 cells; addition of TPA increases the level of mitogenic activity but an analysis of the phenomenon shows that this increase is not due to a higher level of IL1 secretion but rather to a comitogenic activity that devel

When animals are exposed to cigarette smoke, the concentration of carbon monoxide in blood is rapidly increased, so that intensive inhalation tests cannot be carried out. A simple apparatus is described to expose Rats alternatively to cigarette smoke

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
