Effect of intrastriatal morphine (1, 10 or 100 μM) on the extracellular concentration of dopamine (DA) in the rat striatum. Morphine (MO) was adminstered intrastriatally via microdialysis probe instead of Ringer solution as shown by the shaded horizontal bar. All values are presented as percentages of the basal level±s.e.mean (n=5). Contrast analysis after analysis of variance for repeated measurements; 0–220 min: Morphine 100 μM vs Ringer P<0.001.
