Fig. 3From: Telmisartan protects chronic intermittent hypoxic mice via modulating cardiac renin-angiotensin system activityACE 2 staining in myocardial cells of mice from four experimental groups. a & b: CIH group; c & d:ARB group; e & f:blank control group; g & h: air control group. Immunohistochemistry was performed on the cardiac apex sections as described in Materials and methods. The expression level of cardiac ACE 2 was highest in ARB group followed by CIH group compared with the two control groups.
