Untersuchungen über Bildung und Weitergabe von Drüsensekreten beiFormica (Hymenopt. Formicidae) mit Hilfe der Radioisotopenmethode

Summary Marking experiments with the tracer isotope P³² had the result that food-secretion of ants is mainly formed in the pharyngeal gland, then reaches the crop through the exit channel of the gland, where it is stored and released again, on regurgitation-stimuli, to and and larvae as well as workers.     

Über den Einfluss isotopischer und nichtisotopischer Träger auf die Verteilung von Radiostrontium im Organismus der Ratte

Summary Investigating the influence of isotopic or nonisotopic carriers on the behaviour of Sr⁹⁰ in the rat, calcium was found to be ineffective, whereas magnesium was essentially more effective in reducing the deposition of Sr⁹⁰ in the skeleton as equimolar amounts of stable strontium. According to these results, neither calcium nor magnesium can act as ‘biological’ carrier for radiostrontium.      

Untersuchungen über den Ascorbigengehalt von Kohlrabi(Brassica oleracea v.gongylodes) während der Vegetation und den Zusammenhang zwischen Ascorbigen und Wachstum bei den Pflanzen der Familie Brassicacae

Summary The distribution of ascorbigen in various organs of kohlrabi during vegetation suggests that ascorbigen probably plays a part in the metabolism of the indole growth-substances of numerous Brassicacae.
