Fig. 2. Effect of HED on the myocardial structure of mice. The microscope magnification is 20 times. (A) Comparison of the cross-sectional area of hearts in each group when the hearts of mice were stained with WGA. Green fluorescence represents the myocardial cell membrane, and blue represents the nucleus. (B) Comparison of the cardiac collagen area ratio in mice upon Masson staining. Red indicates cardiomyocytes, and blue indicates collagen. db/db group vs. db/m group, *P < 0.05; db/db + HED groups vs. db/db group, **P < 0.05.
