(A,B) The effects of enalapril (10 µM) and (C,D) losartan (10 µM) on the concentration-response curves for phenylephrine and (E) densitometric analysis of the western blot for AT₁ in aortic rings in control (CT) conditions or HgCl2.

<p>Results (mean±SEM) are expressed as a percentage of the response to 75 mmol/l KCl. *<i>P</i><0.05 by ANOVA. (E) Densitometric analysis of the western blot for angiotensin receptor 1 (AT1) protein expression in aortic rings cultured in the absence (CT) of HgCl₂ and after acute incubation with HgCl₂. *<i>P</i><0.05 by Student’s <i>t</i>-test. Number of animals used in parentheses. Representative blots are also shown.
