Mature and aged, male and female mitochondrial free matrix calcium (nM/mg mitochondrial protein/mg dry weight) for Control (after 75 minutes of perfusion), GI, K/Mg and K/Mg + DZX (after 30 minutes of equilibrium, 30 minutes of ischemia. 15 minutes of reperfusion). All results are shown as mean (SEM) for n = 6 animals for each group. P values for specific comparisons between male and female animals, within an age group were calculated using a t test. Significant differences at p < 0.05 are shown in bold face.

DZX = diazoxide; GI = global ischemia; K/Mg = potassium/magnesium.
