title: Influence of prior heat treatment on the effects of heat alone or combined with X-rays on mouse stromal tissue.
abstract: The tumour bed effect assay was used to study the sensitivity of mouse stromal tissue to heat applied alone or combined with irradiation. Prior heat treatment, 30 min at 43 degrees C, of the tumour bed led to thermotolerance. After priming, thermotolerance developed fully within 24 h and it had disappeared completely after about 10 days. The kinetics of development and decay of thermotolerance in this slowly dividing tissue is similar to that which we had observed previously in skin. When decay rates of several normal tissues with different proliferation characteristics are compared, it is obvious that there is not a clear relationship between proliferation rate of the presumed target cells in the tissue and thermotolerance decay rate.
