Figure 2: Cinnamophilin decreased superoxide radical production in the ischemic brain. In situ detection of intracellular superoxide radical production was measured by dihydroethidium (DHE) in the ischemic brain. The brain sections were double stained with DHE (red) and DAPI staining (blue). The CINN-treated rats had a significant decrease in the intensity of DHE signals, compared to the the vehicle-injected controls. Data are presented as mean ± standard deviation (S. D.), and n=6 per group. *P<0.05 compared with vehicletreated controls by using the unpaired Student’s t test.
