Figure 1From: Amphetamine and pseudoephedrine cross-tolerance measured by c-Fos protein expression in brains of chronically treated ratsPseudoephedrine induced c-Fos expression. Western blot analysis was used to measure the acute pseudoephedrine (40 mg/kg, i.p) induced c-Fos expression in striatum and nucleus accumbens. c-Fos protein was detected 1.5 h after saline and pseudoephedrine injection.Back to article page
