  1. Groups: Non-irradiated (noIRnoHBO) and Irradiated (IRnoHBO) - animals without HBO; and Non-irradiated (noIRHBO) and Irradiated (IRHBO) - animals’ treatment with HBO. Different upper case letters within rows indicate significant differences for systemic condition factor (non-irradiated or irradiated); different lower case letters within rows indicate significant difference for HBO therapy factor (non-HBO or HBO therapy). Comparison performed by Tukey test (p < 0.05)
