The protective effect of linoleate against x-irradiation in the rat has been confirmed.
On the basis of the average length of survival, and from comparison of the periods required for LD25, LD50 and LD75 to be reached in male rats subjected to x-irradiation, it was demonstrated that the protective effect of ethyl linoleate became greater with increasing dosage.
The optimum dosage for protection against x-irradiation injury, in male rats, probably exceeds 100 mg per day.
