Abstract
The mode of action of arsenic in preventing chronic selenosis (Moxon, 1938) has not been clarified. Klug et al. (1950) concluded that arsenic does not retard tissue deposition of selenium in rats, and Peterson et al. (1950) reported that it has no effect on absorption, excretion, or tissue deposition of selenium. On the other hand, arsenic has been reported to reduce selenium exhalation in rats (Kamstra and Bonhorst, 1953), inhibit selenium uptake by yeast, and block the transport of selenium from the blood to the liver of the rat (Palmer and Bonhorst, 1957). Since, therefore, alteration of the metabolism of selenium by arsenic appears likely, this work was undertaken to determine whether arsenic might reduce selenium deposition in eggs, accounting for the apparent prevention by it of the effects of selenium on egg hatchability (Moxon and Wilson, 1944).Eight Single Comb White Leghorn yearling hens were placed in each of…
