Figure 2 Comparisons of the effects of carvedilol versus metoprolol and propranolol (mean ± SE). (a) Survival rate (n = 20 in each group). Circles = control group; squares = 30-mg/kg propranolol treatment group; diamonds = 30-mg/kg metoprolol treatment group; triangles = 10-mg/kg carvedilol treatment group. *p < 0.05 versus control, propranolol, and metoprolol groups. (b) Levels of IFN- in the heart on day 7 (n = 5 in each group). *p < 0.05 versus control and metoprolol groups. (c) Levels of IL-12 in the heart on day 7 (n = 5 in each group). *p < 0.05 and #p < 0.01 versus control and metoprolol groups. (d) Myocardial virus concentration on day 7 (n = 5 in each group). *p < 0.05 versus control and metoprolol groups. Carv =carvedilol; Met = metoprolol; Prop = propranolol.
