RESUMO
Airborne spora in the atmosphere of Besançon were weekly determined, searching links between appearance of species and seasonal allergies. By comparison of the results of the two years, it is easy to see many variations. At first, the number of colonies collected is very different, 2,990 colonies in 1988, 9,841 in 1989. During 1989, some genera are present in greatest quantities. It is the case of Cladosporium and Epicoccum in summer and Aspergillus in autumn. For the allergologists, Alternaria, very abundant during 1989, is perhaps the outstanding incident, this genus being considerated as very allergenic.

The study of the toxicity of three mercuric derivatives on the growth of Euglena gracilis Z. shows that these chemicals act according to two different ways: quick inhibition of the growth for a peculiar concentration or progressive inhibition characterized by a lag-phase, the significance of which is discussed.

The authors studied disturbances of lipid clearance in cases of aseptic osteonecrosis of the femoral head by means of an induced intravenous hyperlipemia test. With reference to investigations in 19 patients, the authors first draw attention to the frequency of ethylism and of fatty degeneration of the liver (13 patients). A significant decrease was noted in the coefficient of lipid clearance in the 19 patients. This was particularly marked when fatty degeneration of the liver was present. The etiological role of these anomalies should be considered, as fatty degeneration and hyperlipaemia may also be found in other pathological conditions responsible for primary osteonecrosis of the femoral head (corticotherapy).
