Effect of Size and Age of Female Rats on their Response to the Methæmoglobinogenic Action of 3′;-Methyl-4-dimethyl-aminoazobenzene

Abstract

DURING a study of the methæmoglobinogenic activities of various carcinogenic agents, it was observed that a standard dose of the azo dye, 3′-methyl-4-dimethylaminoazobenzene (16.5 mgm. in 0.55 ml. of arachis oil per 100 gm. body-weight), induced a greater and more persistent methæmoglobinæmia in old female albino rats than in young female rats.
