Fig. 8. Immunochemical image for confirmation of PSD-95 expression by DHA treatment. (A) Immunochemical images showed that PSD-95 positive cells (red) were few expressed in the EC group cortex. In DHA treatment group, PSD-95 expression was considerably increased in rat cortex compared to the EC group. (B) In DHA treatment group, PSD-95 positive cells were increased in rat striatum owing to DHA treatment. (C) The graph showed the percentage (%) of PSD-95 positive cells to compare the difference of PSD-95 fluorescence intensity. Differences were considered significant at **p<0.01 (t-test via EC group). Scale bar=100 µm, PSD-95: postsynaptic density protein 95 (PSD-95); red, 4', 6-diamidino-2-phenylindole (DAPI): blue. NC: normal control group, EC: experimental control; reperfusion 24 hr after MCAO injury, DHA: DHA treatment and reperfusion 24 hr after MCAO injury.
