The effect of cycloheximide and carbon tetrachloride in Ehrlich ascites tumour-bearing mice

Treatment with cycloheximide and a hepatotoxic dose of CCl4 (well tolerated in normal animals) is acutely toxic in animals bearing the Ehrlich ascites tumour. Reduction in tumour load 4 hr after the administration of cycloheximide and CCl4 is life-saving: treatment with a hepatotoxic dose of CCl4 30 hr before challenge with cycloheximide and CCl4 also nullifies that otherwise life-threatening treatment.
