Table 1.

Basal dialysate levels of DA, DOPAC and HVA from the striatum of animals treated for eight days with vehicle or calcitriol. Dialysis experiments were performed three weeks after the final day of treatment.

	Striatal dialysate level (nM)
Calcitriol Dose	DA	DOPAC	HVA
Vehicle	4.03 ± 0.44	1575 ± 82	911 ± 39
0.3 μg/kg/day	4.96 ± 0.41	1699 ± 84	982 ± 38
1.0 μg/kg/day	5.32 ± 0.44	1779 ± 86	1012 ± 47
3.0 μg/kg/day	5.77 ± 0.60	2056 ± 43a	1116 ± 26a

Values are mean ± SEM from 8 animals per group.
