TSPO quantification in forebrain of X-rays and protons exposed (only at their thoracic spinal columns) rats: Results are mean +/- SE (Standard Error) of TSPO specific binding, expressed in nCi/mg in various brain regions of rat in control (n = 3), Proton irr = 3 and X-rays- irr = 3 rat brain regions after nine months of exposure to X-rays and protons to their thoracic spinal columns.

Non-specific binding assessed in the presence of excess unlabeled PK11195 was subtracted from all measurements. Two ways ANOVA reveals highly significant effect between the group (p<0.0001) and of region (p<0.0069). Subsequent post hoc analyses were performed using Fisher's PLSD test.
