Conclusion the increase in early expression of NG2 and O4 and the number of oligodendrocyte precursor cells after wholebrainirradiation of rats is related to the observation time-point.

Methods to determine, by immunofluorescence histochemical method, NG2 and O4-positive cells in the cortex and hippocampal CA1 area of SD rats early after single dose whole-brainirradiation.
Semiquantitative analysis of IL-6 in the hippocampus was done at different time and dose level after whole-brainirradiation with reverse-transcription polymerase chain reaction (RT-PCR).
