Figure Lengend Snippet: ˙ OH production by intrastriatal administration of AngII (top) and the effects of AT1R and AT2R antagonists (middle) and NOX and Rac inhibitors (bottom) on AngII-induced ˙ OH production. AngII (100 nmol/2 μL or 200 nmol/2 μL) was dissolve in sterilized saline and administered into the striatum at 0.1 μL/min for 20 min. Losartan (1 mM), PD123319 (100 μM), DPI (100 μM), AEBSF (100 μM) and EFT1864 (100 μM) were dissolved in the perfusing medium and administered throughout the experimental period. The inserted graphs depict basal ˙ OH production in terms of 2,3-DHBA formation. Each column or symbol with a vertical bar indicates the mean ± SEM. The horizontal bars indicate administration of AngII. *Significant difference (p < 0.05) from 0 nmol AngII (saline alone) (top) and “None” (neither antagonists nor inhibitors) or 100 nmol AngII alone (middle and bottom) by one-way ANOVA followed by Dunnett’s test.
