Figure 5: Effects of hinokitiol on the protein expression of iNOS in MCAO-reperfusion-induced cerebral homogenates. Rats were pretreated with hinokitiol (0.2 mg/kg or 0.5 mg/kg) before ischemia and compared with the vehicle group or the sham group. All groups are represented as ipsilateral hemisphere. Data are expressed as the means ± SEM ( ). compared with sham control group; and compared with vehicle control group.
