|Title:||Effect of angiotensin II on striatal dopamine release in the spontaneous hypertensive rat.||Austin Authors:||Jenkins, T A;Chai, Syn Y;Mendelsohn, Frederick AO||Affiliation:||University of Melbourne, Department of Medicine, Austin and Repatriation Medical Centre, Heidelberg, Victoria, Australia||Issue Date:||8-Jul-1997||Publication information:||Clinical and Experimental Hypertension (new York, N.y. : 1993); 19(5-6): 645-58||Abstract:||We have previously demonstrated that angiotensin II stimulates the release of dopamine from the normotensive rat striatum via the AT1 receptor. In this study, the effect of angiotensin II-stimulated striatal dopamine release in the spontaneous hypertensive rat was compared to normotensive controls. In the spontaneous hypertensive rat, angiotensin II stimulated dopamine release to 169 +/- 13% (P < 0.05) in the experimental period, with levels remaining high in the recovery phase, 158 +/- 16% (P < 0.05). This effect was not significantly different from the response in normotensive controls, in which angiotensin II stimulated dopamine release to 149 +/- 18% (P < 0.05) in the experimental period, with the effect also persisting through the recovery period, 244 +/- 62% (P < 0.05). Thus, despite reports of increased activity of the brain angiotensin II and dopamine systems in the spontaneous hypertensive rat, there is no evidence of abnormal regulation of the striatonigral dopamine system.||Gov't Doc #:||9247745||URI:||http://ahro.austin.org.au/austinjspui/handle/1/13537||URL:||https://pubmed.ncbi.nlm.nih.gov/9247745||Type:||Journal Article||Subjects:||Angiotensin II.pharmacology
