TOXICITY OF 1, 2‐DIMETHYLHYDRAZINE IN MICE: EFFECT OF DIET AND DEVELOPMENT OF TOLERANCE

Abstract
The effect of diet on the lethality of 1, 2‐dimethylhydrazine (DMH) injections was investigated using Swiss mice. Mortality was highest when mice were fed a nutrient‐diluted/high‐fat diet, was intermediate with a nutrient‐diluted/low‐fat diet and was lowest with laboratory chow. Wheat bran was not protective. Mice developed tolerance to DMH after receiving several injections of progressively increasing dose.
