Anti-neoplastic and immunostimulatory effects of low-dose X-ray fractions in mice.

abstract：:A procedure based on a logistic regression model was used to estimate the dose-modifying effect of chemotherapy on the response of normal tissues to radiation. The magnitude of this modifying effect is usually expressed as a dose-effect factor (DEF). Values > 1.0 indicate an enhancing effect of chemotherapy while valu...

abstract：:The rate of recovery from radiation damage, as a function of dose per fraction, was investigated in mouse skin. Two different experimental designs were used, both incorporating the neutron top-up technique which enables the X-ray dose per fraction to be kept constant whilst changing the interfraction interval. Either ...
