Spatial solute concentration profiles resulting from in vivo microdialysis were measured in rat caudate-putamen by quantitative autoradiography. Radiolabeled sucrose was included in the dialysate, and the tissue concentration profile measured after infusions of 14 min and 61.5 min in an acute preparation. In addition, the changes in sucrose extraction(More)
We applied in vivo microdialysis to assess the effects of dopaminergic and beta-adrenergic receptor stimulation on cyclic AMP efflux in rat striatum under chloral hydrate anesthesia. Dopamine (up to 1 mM) infused for 20 min through the probe did not increase cyclic AMP, whereas both the selective dopamine D1 agonist SKF 38393 and D2 antagonist sulpiride(More)
