title: Enhancement of radiation effect on mouse intestinal crypt survival by timing of 5-fluorouracil administration.
abstract: There is a marked dependence of mouse crypt survival on the sequence of combined drug-radiation treatment and on the time lapse between irradiation and drug administration. When 5-fluorouracil is administered 6 hours after irradiation or later (up to 18 hours postirradiation), crypt survival drops significantly.
