[Time factors in human skin desquamations (author's transl)].

A clinical study of human skin desquamation has provided the variation of the isoeffect curve as a function of the fraction number and overall time. These results have been compared to ELLIS formula (N.S.D.). These results have been compared to relationships related to intestinal mucosa and lung. Differential effects are put in evidence between these tissues as a function of fractionation and overall time. Such differential effects are likely to exist between tumors and normal tissues; however the basic data are still missing for optimizing the time factors of the therapeutic irradiations.
