Tocopherol and local X-ray irradiation of two transplantable rat tumours

The influence of tocopherol in an intramuscular dose of 5 mg/100 g body wt. on the effect of local X-ray irradiation of 2 intramuscularly transplanted tumours in the rat was studied. A significantly enhanced effect of irradiation by tocopherol was found, in contrast to the tumour radioprotecting effect with large doses of tocopherol earlier described in literature.
