    Notes: [Auszug] WE have reported that we were unable to obtain any evidence of œstrogenic activity in rats with benzylidenepyruvic acid and furylidenepyruvic acid or their sodium salts1. These negative results were attributed by Friedmann2 to the use of insufficient doses (100 ...

    Notes: [Auszug] IN view of the results published by E. Friedmann in NATURE of April 20, we decided to investigate the effect upon ovariectomised rats of the two compounds specifically mentioned by him as œstrogenic, namely, sodium benzylidenepyruvate and sodium furylidene-pyruvate. These were prepared and ...

    Notes: [Auszug] WE wish to make the following comments on the communication by E. Friedmann in NATURE of April 20 (p. 622) under the above title:— (1) Dr. Friedmann apparently believes that the œstrogenic activity of synthetic compounds was first observed by Blum-Bergmann1, and afterwards ...

    Notes: [Auszug] IN the last resort, the degree of importance which is attached to the carcinogenic substances depends upon whether such compounds are concerned in the etiology of 'spontaneous' human cancer. Perhaps closely bound up with this question is another unsolved problem of outstanding importance, namely, ...

    Notes: [Auszug] THE bile of bony fishes, like that of birds and mammals, contains acids in which glycine or taurine is conjugated with mono-, di-, and tri-hydroxy derivatives of cholanic acid. On the other hand, Hammarsten1 isolated from the bile of the shark, Scymnus borealis, acids which he ...

    Notes: [Auszug] J. W. COOK1 pointed out that the sterols and bile acids contain in their molecules condensed carbon-ring systems to which are attached a side-chain in such a position that a new 6-membered ring can be formed so as to give the 1: 2-benzanthracene ring system without molecular ...
