Figure 2From: Insulin renders diabetic rats resistant to acute ischemic stroke by arresting nitric oxide reaction with superoxide to form peroxynitriteThe cerebral NO levels were compared in control, DM, and DMI rats. The left (A) and right (B) cerebral NO levels in rats were evaluated by NO/ozone chemiluminescence technique. (C) The ratio of right to left cerebral hemisphere NO level was also evaluated among these groups. Results are expressed as mean ± SEM (n = 7 to 8 per each group).Back to article page
