Passage of Testosterone-4-C14 from the Egg Shell to the Albumin

Poultry Science, 1971
Abstract A variety of substances may be introduced into the egg by immersing 2-4 cm. of the pointed end into prepared solutions (Seltzer, 1956). We have inhibited or eliminated the development of the bursa of Fabricius by dipping the egg into varying concentrations of testosterone propionate (Glick, 1964). We have attempted to determine the amount of

S1 gene sequence analysis of infectious bronchitis virus vaccinal strains (H120 & H52) and their embryo-passaged derivatives

Archives of Razi Institute, 2016
Avian infectious bronchitis is an acute and highly contagious disease that mainly causes respiratory symptoms in poultry. A number of serotypes and variants of the viral agent with poor cross-protection are the major problem to achieve desired immunity ...

Further Studies on Serial Passage of a Mixture of Influenza Viruses in Embryonated Eggs.

Experimental Biology and Medicine, 1951
SummaryUndiluted allantoic fluids were used as inocula for serial passage of a mixture of the PR8 and Lee strains of influenza virus in embryonated eggs. Although wide differences were found in the relative concentrations of the two viruses in the various fluids, the mixture was successfully carried through 52 consecutive passages, and each agent was ...

Eosinophils favor the passage of eggs to the intestinal lumen in schistosomiasis.

Brazilian journal of medical and biological research = Revista brasileira de pesquisas medicas e biologicas, 1988
The release of Schistosoma mansoni eggs to the intestinal lumen of Swiss Webster albino mice is dependent on the peri-ovular inflammatory cells, especially eosinophils. The cells corrode the epithelial basal membrane and provide an easily penetrated environment for the eggs, allowing them to be passively expelled by intestinal peristalsis.
