Zusammenfassung 1. Es wird gezeigt, dass der Effekt von phagozytierten,hitzeabgetöteten Bakterien auf die Atmung von Kaninchen-Leukozytenin vitro von der Virulenz der verwendeten Mikroorganismen abhängig ist.2. Die Tatsache, dasslebende Mikroorganismen nach Phagozytose intrazellulär fortfahren zu atmen, wird demonstriert und deren Beziehung zur Pathogenität der Bakterien diskutiert.

Summary Condensation of benzil with two monosubstituted guanidines in the presence of 50 mol% of potassium hydroxide leads to the formation of 2-(subst. imino)-4, 4-diphenyl-imidazolidin-5-ones (Ia, b); by reduction of the potassium hydroxide used the formation of these products is more or less driven back in favour of the formation of 3-substituted 5, 5-diphenyl-glycocyamidines (Ic, d). A possible explanation for these orientation phenomena is given.

Harvey, with Scilliglaucosidin-19-ol and 3-Epi-Scilliglaucosidin-19-ol showed its identity with the first named compound. This proves that the so called Nabogenin was a mixture consisting mainly of Scilliglaucosidin.
