Fig. 7From: Model difference in the effect of cilostazol on the development of experimental pulmonary hypertension in ratsCollagen staining in the right ventricle. Representative photomicrographs of collagen staining in the right ventricle detected using Masson’s trichrome staining. Images were captured with a microscope at × 400 magnification, and the scale bars in lower right corner represent 50 µm. A: Air/CLZ- (control), rats exposed to ambient air and fed rat chow without CLZ; B: MCT21/CLZ-, rats injected with MCT and fed rat chow with CLZ; C: MCT21/CLZ +, rats injected with MCT and fed rat chow without CLZ; D: CH/CLZ-, rats exposed to chronic hypoxia and fed rat chow without CLZ; E: CH/CLZ +, rats exposed to chronic hypoxia and fed rat chow with CLZ. Fibrosis scale: 0 = normal, (+) = mild, and (++) = moderate. The blue color indicates collagen (allows)Back to article page
