Fig. 9From: Acorus tatarinowii Schott extract reduces cerebral edema caused by ischemia–reperfusion injury in rats: involvement in regulation of astrocytic NKCC1/AQP4 and JNK/iNOS-mediated signalingEffects of SCP-0.5 g and SCP-1 g treatments on MMP-9 and ZO-1 expression in the penumbra of the cerebral cortex. Representative images show a MMP-9 and b ZO-1 expression in the penumbra of the cerebral cortex in the Sham, Model, SCP-0.25 g, SCP-0.5 g, and SCP-1 g groups 3 d after reperfusion. The bar graphs display the numbers of c MMP-9- and d ZO-1-positive cells in the penumbra of the cerebral cortex among the experimental groups. *P < 0.05 compared with the Sham group; #P < 0.05 compared with the Model group. Arrows in (a) and (b) point to MMP-9- and ZO-1-positive cells, respectively. Scale bar = 10 μmBack to article page
