BW245C (0.02, 0.2, and 2.0 mg/kg) in WT mice results in a significant increase in CBF, but this effect of this treatment is absent in DP1 mice. BW245C attenuates functional deficits after stroke. BW245C significantly reverses these conditions that neurologic deficit is significantly augmented, whereas locomotor activity is significantly reduced after stroke in WT mice. BW245C (0.2 mg/kg) injection 1 h after stroke results in a significant decrease in brain infarction in WT mice, whereas the effect of this treatment is not observed in DP1 mice. BW245C improves CBF during and after stroke. BW245C results in significantly prolonged bleeding compared with the vehicle-treated group. BW 245C (100 nM) does not significantly increase MBP-positive eosinophils in esophageal epithelium in OVA-sensitized guinea pigs.
