Values are means ± SE, n = 6–8 mice. Cardiac function was recorded by echocardiography (Vevo 770) in homeothermically heated (to 36°C), unconscious (1.8% isofluorane) naive and sham-operated animals, and 6 and 24 h post-LPS and post-CLP.
P < 0.05,
P < 0.01,
P < 0.001 relative to sham/naive, one-way ANOVA + Bonferroni post hoc test.
