Fig. 2From: Telmisartan protects chronic intermittent hypoxic mice via modulating cardiac renin-angiotensin system activityAng II 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 AngII was highest in ARB group followed by CIH group compared with the two control groups. Magnification: a, c, e and g: 100×; b, d, f and h: 400×. scale bar, 100 μmBack to article page
