Effect of gender on training-induced vascular remodeling in SHR. S.L. Amaral and L.C. Michelini.
Figure 2. Upper panels, Photomicrographs taken from transverse sections of gracilis muscle arterioles of sedentary (s, left panel) and trained (t, right panel) spontaneously hypertensive (SHR) male rats. Arrows indicate wall thickness; bar = 25 mm. Lower panels, Effects of hypertension and training on arteriolar wall/lumen ratio in different tissues of sedentary (S) and trained (T) normotensive (WKY) and SHR male rats. Mean values correspond to 11-40 arterioles in the myocardium, 9-18 in the kidney and 5-9 arterioles in the skeletal muscles taken from 3-4 rats per group. *P < 0.05 vs WKY; †P < 0.05 vs S (two-factor ANOVA).
