Effects of tiron and DPI on lucigenin-enhanced chemiluminescence signals in brain tissue of control mice, R + /A + mice without ICH (R + /A + ICH(−)), and R + /A + mice with ICH (R + /A + ICH(+)). (A) Anterior quarter of brain, (B) second quarter of brain, (C) third quarter of brain, and (D) posterior quarter of brain. Values are means±s.e.m. (n = 8 in each group); RLU, relative light units. *P < 0.05, **P < 0.01 versus respective brain tissue.
