title: Effects of topically-applied olive oil on the response of hamster skin to single or multiple doses of 230kV X-rays.
abstract: The effects of topically-applied olive oil on the response of hamster skin to single or multiple doses of X-rays has been studied. The olive oil was applied either 15 min or 1 hour before the radiation exposures. The treatment did not alter the temporal pattern of development and recovery from the radiation injury. For single exposers, olive oil did not alter the 1- to 30-day average skin response. However, when it was administered at each treatment when three radiation fractions were given over a 4-day interval (3 fractions/4 days), a significant increase in the amount of dose recovered was found compared with control irradiated animals. For controls, the average amount of dose recovered per fractionation interval, (Dn-D1)/(n-1), was about 505 rad. For animals treated with olive oil 15 min before irradiation, it was about 720 rad; and for those treated 1 hour before irradiation, it was 782 rad. The data indicate a definite radioprotective effect of topical administration of olive oil, but at present the mechanism is not known.
