Radiation survival: Improved rates following chlortetracycline administration.

Oral administration of chlortetracycline to mice before and after 1100 rads whole body x-irradiation resulted in a substantially enhanced survival rate (88%) over nontreated animals. This occurred in spite of severe pancytopenia as illustrated by the depression of marrow DNA and leukocyte values. Antibiotic administration solely in the preirradiation or postirradiation periods produced a smaller increase in survival (56%). The results are attributed to the control of endogenous and exogenous bacterial infection before and after irradiation rather than a radioprotective effect.
