a ELA level in plasma determined by ELISA; b, c systolic blood pressure (SBP), diastolic blood pressure (DBP), mean arterial pressure (MAP) and heart rate (HR) in a conscious state; d representative photographs of aorta and mesenteric artery (MA) by hematoxylin and eosin staining and Masson’s staining; e–h media thickness, lumen diameter, ratio of media thickness to lumen diameter and intima-media thickness (IMT) in aorta and MA. Arrows indicate the internal elastic lamina (IEL); Arrowhead denotes the endothelial cells. IMT is defined as the distance from endothelium to media-adventitia transition. n = 6 per group. Values are mean ± SEM. *P < 0.05.
