mRNA expression of interleukins 1 beta (IL-1beta) and 6 (IL-6) on myocardial tissue after LLLT.

<p>Myocardial infarction remote area presented an acute inflammation of the myocardium, as observed as an increased of cytokines IL-1beta and IL-6 mRNA in the left ventricles (LV) of MI rats (n = 28). A downregulation of IL-1beta (<b>A</b>) and IL-6 (<b>B</b>) mRNA expression was detected in the group MI+Laser (n = 30), suggesting an anti-inflammatory effect of LLLT. Control group was composed of 14 rats. Data are means ± S.E.M. *p<0.05 <i>vs.</i> Control group; ^#p<0.05 <i>vs.</i> MI group. P values given were determined by ANOVA.
