Histological analysis following acute ethanol exposure.
(A) Hematoxylin and eosin (H&E) staining micrographs of transverse sections of myocardium (magnification ×400; scale bar: 20 µm) and (B) quantitative analysis of cardiomyocyte cross-sectional area using measurements of ∼20 cardiomyocytes in each group. Twenty-four hours after ethanol administration, the cardiomyocyte transverse cross-section area was significantly increased in the H&E staining sections compared with the control group. Eth indicates ethanol. *p<0.05 versus control.
