Abstract
Angiotensin II (A II) (10(-6) M, 10(-5) M, 5 . 10(-5) M) stimulated the spontaneous release of [3H]dopamine (DA) continuously synthetized from [3H]tyrosine in striatal slices of the rat. The A II-evoked release of [3H]-DA was prevented when slices were superfused with a calcium-free medium containing EGTA 5 . 10(-4) M. It was also suppressed in the presence of the potent antagonist Sar1-Ile8-angiotensin.
摘要
血管紧张素II（A II）（10⁻⁶ M、10⁻⁵ M、5×10⁻⁵ M）刺激大鼠纹状体切片中由[³H]酪氨酸持续合成的[³H]多巴胺（DA）的自发释放。当切片在含有5×10⁻⁴ M乙二醇双乙醚二胺四乙酸（EGTA）的无钙培养基中灌流时，A II诱发的[³H] - DA释放被阻止。在强效拮抗剂Sar1 - Ile8 - 血管紧张素存在的情况下，它也受到抑制。
