Time course of effects of administration of JJC8-016 (A) (10, 30, 50, 100 mg/kg i.p., n= 5–7), JJC8-088 (B) (10, 32, 56 mg/kg i.p., n= 4–6) and JJC8-091 (C) (10, 32, 56 mg/kg i.p., n= 5–6) on DA levels in dialysates from the NAS in Swiss Webster mice. Results are means, with vertical bars representing SEM, of the amount of DA in 10-min dialysate samples, expressed as percentage of basal values, uncorrected for probe recovery.
