Sensitivity of radiotherapy on the cells in midsection and edge of glioma / 临床神经病学杂志

ABSTRACT

Objective To study the sensitivity of radiotherapy on the cells in midsection and edge of glioma. Methods The glioma models were established in SD rats and exposed to X radiation. Proliferating cell nuclear antigen (PCNA), apoptosis rate and cell phase of the cells in the midsection and edge of glioma were detected by immunohistochemical assay, terminal transferase dUTP nick ending labeling (TUNEL) and flow cytometry. Results Immunohistochemical assay showed that PCNA-LI of the edge cells was significantly lower than that of midsection cells ((P
