Astaxanthin alleviates heart injury induced by PM2.5 in mice. A–E Hematoxylin and eosin (HE) staining of heart tissue sections from different groups (Scale bar = 50 μm). F The myocarditis score of heart in each group. The activities of Lactate dehydrogenase (LDH) and creatine kinase (CK) activity in heart heart tissue (G, H) and serum (I, J) were measured. Values are expressed as mean ± SEM (n = 6). *p < 0.05 difference from the control group; **p < 0.001 difference from the control group; #p < 0.05 difference from the PM2.5 exposure group; and ##p < 0.001 difference from the PM2.5 exposure group
