Inactivation of glioma cells via Gd-NCT. Inactivation of tumor cells (A) F98 cells, (B) LN229 cells, following the equation: Inactivation = 100% - Total Survival. Neutron fluences were 3.6 to 4.05 · 1012 n/cm2 for F98 cells and 2.4 to 2.7 · 1012 n/cm2 for LN229 cells. Results are arithmetic means of three independent experiments, error bars represent SEM. Total survival is based on the irradiated medium control without drug, i.e. the inactivation value shows the specific effect of the different Gd-formulations. Significance levels (ANOVA, Tukey’s multiple comparison) are * p < 0.05, ** p < 0.01 and ***p < 0.001, liposomal formulation compared to Magnevist.
