Fig. 4. Effect of preconditioning with diazoxide (Dz) and isoflurane (Iso) on myocardial infarct size. Experimental protocol is shown in protocol 1 in figure 1. Each bar represents the mean ± SEM of seven experiments. *P < 0.05 compared with control. †P < 0.05 compared with isoflurane. HD = 5-hydroxydecanoate; LV = left ventricular.
