Figure 6. RWPs improve the aging-related over-expression of several components of angiotensin system in the mesenteric artery.
The expression level of angiotensin II (Ang II), AT1 receptor (AT1R), AT2 receptors (AT2R) and angiotensin-converting enzyme (ACE) was determined by immunohistochemical staining. Left panels show representative immunofluorescence staining; right panels corresponding cumulative data. Results are shown as mean ± SEM of 4 different rats. *P<0.05 indicates a significant difference versus the young rat control group and # P<0.05 versus the middle-aged rat control group. All micrographs were taken at the same magnification.
