[Medical treatment of Raynaud's syndrome].

The authors review the drug treatment of Raynaud's disease. Many substances have been used including nitrate derivatives, calcium antagonists, alpha blockers, angiotensin converting enzyme inhibitors, prostaglandin E1, E2 and I2, and ketanserin. The efficacy of these drugs is often partial and variable. The indications are discussed with respect to the clinical course and etiology of the Raynaud's phenomenon.

[Aspects of professional hygiene in dental technical laboratories].

Investigations on hygiene and sanitary conditions in a laboratory for dental techniques consisted in physico-chemical determinations on microclimate (temperature, humidity, air currents), determination of dust particles (suspended and sedimented), determination of gases (CO, CO2, NO2, NH3, SO4(2-), chloride ions), and determination of microelements (Fe, Cu, Zn, Ni, Cd). In certain conditions the concentrations for dust, NO2, NH3, SO2(4-), chlorine and Cu were above the maximal accepted levels. Measures should be taken for the prevention and for the elimination of these noxious factors by implementing optimal hygienic conditions (heat, humidity, ventilation), by reducing gas emanations, by using protections equipment (mask, eyeglasses, gloves), and by periodic controls of the health status of dental technicians.

[Technical note on the isolation of arboviruses by inoculation in young mice: preparation of the mosquito brei].

Studying the effects of centrifugation and deep freezing on the quantity of yellow fever virus in a grinded pool of mosquitoes, the authors followed the mortality rate of inoculated baby mice with twenty five artificially infected mosquitoes treated in four different ways. The statistical analysis of the results show that centrifugation and deep freezing have both an effect on the titer of virus and that the addition of the two treatments have an effect superior to the addition of the separate effects of each of them. The authors propose a new technic for the preparation of pools of mosquitoes, without centrifugation or deep freezing.

[A serological survey of arboviruses in the human population of Senegal].

2,457 serum samples collected during an epidemiological survey on treponematosis in Senegal by the W. H. O. IR051 team in five areas of Senegal between 1972 and 1975 were studied for arbovirus antibodies using hemagglutination inhibition test. In addition 998 were studied using CF test and 1012 in neutralization test with yellow fever virus. The prevalence of arbovirus antibodies is important in all the country and does not vary basically between the different areas. In group A, chikungunya antibody is the most frequent and Sindbis antibody was found only in areas where migrant birds are resting. There is evidence of recent yellow fever infection in Upper Casamance and in Eastern Senegal. Most of the children are not immune and have to be immunized. Zika and Wesselsbron viruses show activity in all the areas and West-Nile, as Sindbis, is related to areas where birds are numerous. Bunyamwera virus activity is low.

[Long-term infection of a cell culture from newborn mouse brain with the FNV strain of yellow fever virus (author's transl)].

A cell culture from brains of one day old mice was infected with a high multiplicity of the French neurotropic strain of yellow fever virus (FNV); the infected cell culture produced and released infectious FNV for more than 180 days post-inoculation with titres between 10(0.6) and 10(6.4) PFU/ml. The cell sheet exhibited some rare plaques of round cells with a slow centrifugal extension; the destruction of the cell sheet was not complete before 200 days post-inoculation.
