Analysis of Mechanisms for Increased Blood Pressure Variability in Rats Continuously Infused with Angiotensin II

<div>Morphological analyses of sections of the aortic arch from control rats and those infused with angiotensin II (Ang II) with or without oral administration of azelnidipine (Azl) over 14 days. (a–c) Representative photos of hematoxylin eosin-stained aortic sections. (d–f) Quantitative analyses of medial and luminal area and media to lumen ratio. <span class="nowrap"><svg height="9.10327pt" id="M20" style="vertical-align:-0.3499298pt" version="1.1"
