Acute Hypobaric and Hypoxic Preconditioning Reduces Myocardial Ischemia-Reperfusion Injury in Rats

Figure 5

HIF1α/β actin ratio in the three groups in rat myocardium sampled from the left ventricle just after exposure to each condition. Representative immunoblots from all groups are presented. Arrows indicate positions of HIF1α and β actin bands. Data are shown as median and interquartile range (IQR), n = 4 rats per group.  < 0.05;  < 0.01 vs. normobaric normoxia group by one-way analysis of variance (ANOVA) followed by Tukey’s post hoc test.
