Differentiation Between a Growth-Promoting Factor and a Tumour-Susceptibility Factor in Eggs

SZEPSENWOL 1 reported that feeding a diet composed mainly of cooked eggs to mice resulted in a significant increase in the number of animals spontaneously developing tumours. Denton 2 found that feeding egg yolk increased the growth of chicks. Recently Hradec 3 presented evidence, based on fractiona...

Description
Summary:SZEPSENWOL 1 reported that feeding a diet composed mainly of cooked eggs to mice resulted in a significant increase in the number of animals spontaneously developing tumours. Denton 2 found that feeding egg yolk increased the growth of chicks. Recently Hradec 3 presented evidence, based on fractionation studies, which indicated the identity of the tumour susceptibility-enhancing and the growth-promoting factors. The study presented in this report was undertaken to determine by feeding experiment whether or not these factors were identical.
