Abstract
The effect of microwave whole-body hyperthermia was examined on the takes of tumor after i.v. administration of the tumor single cell suspension. It was shown that the longer the exposure to hyperthermia treatment the higher the number of lung nodules obtained by injection of the same dose of tumor cells. Also, the expression of contact hypersenstivity to oxazolone was strongly inhibited after hyperthermia treatment. It was documented that it is possible to transfer the diminished resistance to tumor with bone marrow, whereas impaired responsiveness to oxazolone was transferred with spleen cells or thymocytes.
