The effect of arsenic upon some oxidation-reduction systems

Abstract

As in the form of arsenite, when in concentrations similar to those found in the skin in arsenical hyperkeratosis, has a retarding action upon 3 oxidation-reduction systems: hypoxanthine and the xanthine oxidase of rat or mouse skin; acetaldehyde and colloidal Pt; and propaldehyde or acetaldehyde, glycine, and phosphate. Arsenates are comparatively inactive. The possible significance of these findings in connection with the nature of arsenic cancer is discussed.
