Fig. 4. Histogram depicting myocardial infarct size expressed as a percentage of the left ventricular area at risk in rats receiving saline (CON) or 1.0 minimum alveolar concentration isoflurane (ISO) in the absence or the presence of 5-hydroxydecanoic acid (ISO + 5-HD) or N -acetylcysteine (ISO + NAC). * Significantly (P < 0.05) different from control. † Significantly (P < 0.05) different from 5-HD, ISO + 5-HD, NAC, and ISO + NAC.
