CAT and Atrophy: Similarly, catalase activity in the brain was higher in the low 7 day lesion volume group (43.7768 ± 2.2649 nmol/min/mg protein) relative to the high group (36.7293 ± 2.3542 nmol/min/mg protein; p = 0.0465) (Figure 4C), as well as in the low 42 day swelling/atrophy group (44.2151 ± 2.8407 nmol/min/mg protein) compared to the high group (36.2910 ± 1.3349 nmol/min/mg protein; p = 0.0225) (Figure 4D).
