    Notes: [Auszug] THE retardation of the growth-rate of tumours in experimental animals by chemical compounds and by extracts of tissue has been the subject of numerous investigations, and the fact that inhibition can be produced by so large a number of compounds suggests some general effect on metabolic ...

    Notes: [Auszug] Starting with phthalimide containing labelled nitro-gen, we synthesized and diazotized labelled aniline and coupled it with P-naphthol. By reduction we split the product to aniline and a-amino-(3-naphthol. If resonance of the above kind exists, the labelled nitrogen should be equally divided ...

    Notes: [Auszug] THE theory that tissue damage in silicosis is caused by silicie acid formed by solvent action of the plasma on inhaled particles stimulated the study of the solubility of airborne siliceous dusts and of the material^which give rise to them. The investigation of the^solubility of mineral silicates ...

    Notes: [Auszug] DUST particles which reach the alveoli of the lung become engulfed by phagocytic cells which may carry them to the lymph glands. When silica particles are inhaled, a number of phagocytic silica-laden cells remain in the lung and these tend to clump together, forming patphes in which the dust ...

    Notes: [Auszug] When powdered silica is added to water, the concentration of dissolved silicic acid increases rapidly at first but afterwards much more slowly. "All sizes of quartz particles behaved as if a soluble fraction of silica was being leached from their surfaces, leaving a relatively insoluble residue, or ...

    Notes: [Auszug] At 85-90C. chrysotile gives an extract containing appreciable amounts of monosilicic acid and magnesium, for example, 0-5 gm. chrysotile in 100 ml. water gives 0 -4 mgm. magnesium and 0 -2 mgm. or Aosilicic acid per 100 ml. solution after 15 min. When extracted with water at 25 C. for some days, ...
