Vascular morphology.

Aortic histomorphometry was performed with the elastin specific stain Verhoeff’s Van Gieson (VVG) and the collagen specific stain picrosirius red (PSR). A, Representative histological sections are presented according to treatment. B, The medial thickness and adventitial thickness were analyzed to describe the aortic morphological changes in response to the treatments. C, The aortic structural dimensions as measured with VVG and PSR stains. D, The systolic luminal diameter were measured with the M-mode ECHO, collagen content was quantified with PSR histological staining, and elastin content was measured with VVG stain. n = 6. *P<0.05 compared to control, ^ƗP<0.05 compared with BAPN group.
