At 7 days post-MI surgery, we discovered significantly inhibited inflammation activation reflected by reduced CD68+ and CD3+ cells detected in the peri-infarcted area in the curcumin group compared with the placebo group, while no difference in CD68+ and CD3+ cell counts was observed between the high-dose curcumin group (100 mg/kg) and the low-dose curcumin group (50 mg/kg) (Figures 1A–D). Here, CD68 is linked to myocardial infarction.
