Serum cardiac enzyme activities in the rat experiments. (a) LDH activity and (b) CK-MB activity in healthy or MI rats treated with azithromycin (Azith), clarithromycin (Clarith), or erythromycin (Eryth). MI: myocardial infarction, LDH: lactate dehydrogenase, CK-MB: creatinine kinase—myocardial band. Data in each set were presented as mean ± standard deviation, and analyzed separately by one-way ANOVA and Bonferroni’s test. * Different from the vehicle group at p-value less than 0.05. # Different from the azithromycin group of the same experiment at p-value less than 0.05 (n = 4–6).
