    Abstract: Purpose: To determine the late effects of fractionated versus single-dose cranial radiation on murine white matter.: Methods and materials: Mice were exposed to 0 Gy, 6 × 6 Gy, or 1 × 20 Gy cranial irradiation at 10 to 12 weeks of age. Endpoints were ...

    Abstract Purpose: To determine the late effects of fractionated versus single-dose cranial radiation on murine white matter.
    Methods and materials: Mice were exposed to 0 Gy, 6 × 6 Gy, or 1 × 20 Gy cranial irradiation at 10 to 12 weeks of age. Endpoints were assessed through 18 months from exposure using immunohistochemistry, electron microscopy, and electrophysiology.
    Results: Weight gain was temporarily reduced after irradiation; greater loss was seen after single versus fractionated doses. Oligodendrocyte progenitor cells were reduced early and late after both single and fractionated irradiation. Both protocols also increased myelin g-ratio, reduced the number of nodes of Ranvier, and promoted a shift in the proportion of small, unmyelinated versus large, myelinated axon fibers.
    Conclusions: Fractionation does not adequately spare normal white matter from late radiation side effects.
