Measurements of rectal temperature and heart rate were taken before the 30-min coronary occlusion (preocclusion), at 5 and 30 min into the 30-min occlusion, and at 5, 15, and 60 min after reperfusion.  Rectal temperature was continuously monitored and carefully controlled  throughout the experiment, as detailed in the text.  The experimental protocols for the eight groups of mice are specified in the legend to Figure 1.  The measurements reported in this table pertain to day 1 for groups I, II, III, and IV, and to day 2 for groups V, VI, VII, and VIII. Note that heart rate on day 2 (groups V, VI, VII, and VIII) was higher than on day 1 (groups I, II, III, and IV), possibly reflecting the effect of surgical trauma 24 h earlier. Data are means ± SEM.

*P<0.05 vs. group I, #P<0.05 vs. group II.
