Effects of MR on cardiac function in septic rats. Cardiac function including A echocardiograms (n = 6/group), B LVEF (n = 6/group) and C cardiac output (n = 8/group) were measured 2 h after resuscitation treatment. D Mean arterial pressure measurement of the septic rats (n = 8/group). E, F HE stains of cardiac pathological sections and heart injury scores (bar, 40 µm, n = 8/group). The expressions of G cardiac troponin T and H lactate dehydrogenase in venous blood (n = 8/group). I Detection of oxygen supply and consumption of the septic rats (n = 8/group). a: P < 0.05 compared with the sham or normal group, b: P < 0.05 compared with the sepsis or LPS group, c: P < 0.05 compared with the LR group
