title: Evaluation of mouse lip mucosa reactions after combinations of cis-diammine-1,1-cyclobutanedicarboxylate platinum (II) (CBDCA) and irradiation: single and fractionated treatments.
abstract: The influence of CBDCA (JM8) on the radiation-induced mouse lip mucosal reactions has been tested. Both single and fractionated drug doses were used intraperitoneally at 60 mg/kg and 5 X 25 mg/kg respectively. A single injection of CBDCA did not alter the response to a single radiation dose, whether the drug was given at different time intervals from 24 hr prior, to 96 hr after irradiation. A concomitant treatment of daily CBDCA injections and irradiations for 5 consecutive days demonstrated no change of the capacity to repair sublethal radiation damage. When two equal sized radiation doses were separated by 10 days and CBDCA was administered daily from day 3 to 7, the ability to repopulate the lip mucosa epithelium during the radiation-free period was not influenced.
