The vascular expressions of eNOS, α-adrenoceptor (α-AR), MMP9, and elastase. In all four sections, top panel is the bands of proteins and bottom panel is the percent intensity of the ratio of the bands to β-actin. A: The expression of eNOS. B: The expressions of α-adrenoceptor. C: The expressions of MMP9. D: The expression of elastase. Lean: Zucker lean rats. ZDF: ZDF rats. 11w: 11 weeks of age. 19w: 19 weeks of age. 19w + V: 19 weeks of age treated with vehicle. 19w + R: 19 weeks of age treated with Rosi. * p < 0.05 indicates statistical significance when compared with lean rats using student t-test. # p < 0.05 indicates statistical significance in comparison of the two groups using student t-test.
