Absorption, distribution, duration of retention, and excretion of zinc-65 in hens and cockerels


, : Absorption, distribution, duration of retention, and excretion of zinc-65 in hens and cockerels. Untersuchungen uber Aufnahme, Verteilung, Verweildauer und Ausscheidung von Zink 65 in Hennen und Hahnen: 89

Hens and cocks that had received no food for 24 hours were administered 0.82 mu Ci/kg Zn-65 in the crop. Hens absorbed 43.5% of the dose, cocks 54.4% (assuming that all Zn-65 not excreted in 48 hours was absorbed). During the experimental period of 20 days up to 87% of the dose was eliminated.

Selection of high-growth virus variants of strain B/Victoria/504/2000 by serial passage in eggs resulted in three amino acid substitutions, G141E, R162M, and D196Y, in the vicinity of the receptor-binding pocket of viral hemagglutinin. Virus varia...
