Effect of hydrogen fluoride inhalation on lipid metabolism in guinea pigs.

The action of fluoride in vivo (exposure 96 hrs to 7 mg/m3) on the metabolism of cyclic AMP and relationship between cAMP and lipid metabolism was investigated. The mean values for cAMP, non esterified fatty acids and cholesterol were significantly increased after hydrogen fluoride exposure. cAMP is directly responsible for the increased lipolysis. In animals exposed to HF, theophylline injection causes increases of non esterified fatty acids and not produces modification of cholesterol level.

Administration, Inhalation

[Study in vitro of effects of nitric oxide and carbon monoxide on human and rabbit blood (author's transl)].

Fixation of CO on human blood or rabbit blood in presence of NO in similar concentrations is diminished by the formation of methemoglobin and nitrite methemoglobin. NO is oxidised in nitrate. Furthermore, it appears that oxidation of nitrite in nitrate is realised by red-blood cells. Spectrography study of blood trated by NO indicates presence of methemoglobin, nitrite methemoglobin.

Animals

[Comprehensive view of air pollution problems (author's transl)].

Air pollution is treated under various aspects: natural, urban, industrial. Primary polluants are studied and their transformation into secondary polluants (oxidant smog, acid smog). Biologic effects on laboratory animals, human health are tackled.
