Hydrogen and Oxygen Mixture to Improve Cardiac Dysfunction and Myocardial Pathological Changes Induced by Intermittent Hypoxia in Rats

Figure 2

The histopathologic changes from H₂-O₂ mixture treatment during CIH for 35 d. (a) H&E staining showed the cardiac architecture in the left ventricle of the four different groups (scale ); (b) Masson’s trichrome staining showed the collagen deposition in the left ventricle of the heart (scale ); (c) the myocardial collagen volume fractions were counted as shown by Masson’s trichrome staining. vs. normoxia group; vs. CIH group; .
