Effect of fractionated doses of electrons and protons on hair follicles in the albino rat
- New York Univ. (NYU), NY (United States)
A study of the effect of single and fractionated doses of electrons and protons on Albino rat hair follicles has been undertaken. The survival and regrowth curves of hair follicles following irradiation are presented. Temporary hair suppression was evident from the delay in regrowth of new hair, which was about one day of delay per 100 rads for protons. It was found that permanent growth suppression occurred at 4800 rads for electrons and at a dose greater than 1200 rads for protons. The doses required to produce 50% follicle suppression at ten days post irradiation were 700 rads and 2100 rads for protons and electrons, respectively. A fractionation effect was found for both types of radiation with about 60% recovery for protons and 100% recovery for electrons.
