Synergistic Action of Estrogenic Hormone and X-rays in Inducing Thymic Lymphosarcoma of Mice.

Abstract
Synergistic lymphomogenic effects were obtained when estrogenic hormone and X-rays were admd. simultaneously to mice of the Bagg albino and CBA strains. Thymic lymphoid tissue appeared to be more sensitive than other lymphoid tissue. This was also true when X-rays and methylcholanthrene acted synergistically in the dba stock.
