Heart wall anatomical changes in sham-operated (Sham), myocardial infarction-induced (MI), sham-operated and treated with H₂S (Sham+H₂S), and myocardial infarction-induced and treated with H₂S (MI+H₂S) animals. A: Examples of cross-sectional view of the left ventricular (LV) walls of Sham, Sham+H₂S, MI and MI+H₂S hearts. Note: No visible necrosis was found in the LV wall of hearts from Sham and Sham+H₂S mice. B: Collagen-associated (blue) intensity changes in hearts from experimental animals. C: Changes in expression of parstatin protein contents, by immunohistochemistry analysis, in hearts from Sham, myocardial infarction-induced (MI), sham-operated and treated with H₂S (Sham+ H₂S), and myocardial infarction-induced and treated with H₂S (MI+ H₂S) mice. D Bar graph of changes in Sham, myocardial infarction-induced (MI), sham-operated and treated with H₂S (Sham+H₂S), and myocardial infarction-induced and treated with H₂S (MI+H₂S) mice heart tissue. The micrographs were taken under the identical set of conditions for all groups. * P < 0.05 vs. Sham, Sham+H₂S, and MI+H₂S. # p<0.05 vs. MI. n=6 for all group.
