    Notes: [Auszug] Injection of rabbits with a cell suspension prepared from transplantable Ehrlich s mouse carcinoma gives rise to the formation of heterogenetic Forssman antibodies2. But two forms are known of Ehrlich s carcinoma ; (a) the solid tumour formed after subcutaneous inoculation, and (b) the ascites ...

    On the action of sulfanilamide (1944)
    Springer
    Antonie van Leeuwenhoek 10 (1944), S. 1-11 
    Details
    ISSN: 1572-9699

    Notes: Summary The better activity (in vitro) of various sulfanilamide compounds as compared with sulfanilamide itself is only quantitative,i.e., an equal activity is obtained with lower concentrations. It is shown, that the activity of the studied drugs is so narrowly related to their adsorption in the bacteria (B. coli), that probably the varying activity of the studied compounds is due to differences in adsorbability. For different drugs the adsorbed amount was equal for concentrations with equal activity. The concentration of p. aminobenzoic acid which re-establishes growth — in cultures containing the studied compounds in concentrations of equal activity — was equal in all cases. This fact corroborates the hypothesis, that activity and adsorption are correlated and shows, that the mechanism of action (in vitro) is the same in all cases.

    Notes: Summary a. The action of sulfanilamide onB. coli is not influenced by different oxygen pressures. b. Sulfanilamide was shown to act onB. coli andStr. haemolyticus (strainAronson) cultured anaerobically: 1. by addition of thioglycolate. 2. in evacuated Thunberg tubes. c. The obtained growth curves with anaerobic cultures show the same characteristics (lag time of action, influence of inoculum, counteraction by para-amino benzoic acid) of sulfanilamide action as the aerobic controls. The mechanism of sulfanilamide action must be the same in both cases. d. The presented facts are incompatible with the claim ofMain, Shinn andMellon (8) as to the anticatalase activity of sulfanilamide, in anaerobic cultures no hydrogen peroxide being formed.

    Notes: Summary A sulfanilamide activating principle was found to be present in red cells of the horse. This activator substance is active in the rather high dilution of 0.5% haemolysed red cells. The substance or substances are present in the red cells, not in their cell membranes. They seem to be of a protein nature or adsorbed to the protein (haemoglobin). In some media no sulfanilamide action is obtained without the activator. In other media sulfanilamide action, though clearly present, is markedly enhanced. So it must be emphasized, that the substance under discussion is an activator and not a “conditio sine qua non” for the sulfanilamide action and its characteristics. The substance is activating sulfanilamide against streptococci, staphylococci andB. coli. The substance is not present in human blood or in the red cells of sheep, rabbits or mice.
