Effect of rhynchophylline on the microstructure and mitochondria morphology of cardiomyocytes. (A) Representative sections of mouse cardiomyocytes observed under a transmission electron microscope. (B) Representative mitochondrial membrane potential observed under a fluorescence microscope (magnification, ×200). (C) The dynamic change in ΔΨm represented by the ratio of fluorescence intensity of 527 and 590 nm. (D) Adenosine triphosphate content in myocardial tissue. Values are presented as mean ± standard error of the mean. **p < 0.01 vs. control group; #p < 0.05, ##p < 0.01 vs. type 2 diabetes mellitus group.
