Figure 4
Evolution of blood volume (BV, in ml 100 g−1 of brain tissue) in peritumoral, intratumoral and contralateral regions during graded hypoxic hypoxia and reoxygenation (n=9). Peritumoral and contralateral BV were reversibly increased during moderate hypoxia (FiO2 0.12) while intratumoral BV was irreversibly increased during severe hypoxia (FiO2 0.10). *P<0.05 between FiO2 compared to control value (Scheffé F-test). Peritumoral region had a higher BV than contralateral and intratumoral regions. $ P<0.05 between ROI compared to contralateral region at each FiO2 (Scheffé F-test).
