Hematoxylin and eosin staining for cardiac specimens in the two rat experiments. (a) Images for specimens were taken from healthy or MI rats treated with azithromycin (Azith), clarithromycin (Clarith), or erythromycin (Eryth). (b) Histologic scores for healthy rat experiment and (c) Histologic scores for MI rat experiment. MI: myocardial infarction. Data presented as medians, and interquartile ranges for the histologic score in each set, were analyzed separately by Kruskal-Wallis ANOVA and Dunn’s Test. * p-value less than 0.05, ** p-value less than 0.01 different from the vehicle group. # p-value less than 0.05: different from the azithromycin group of the same experiment. ^Cp-value less than 0.05: different from the MI + Clarith group (n = 4–6).
