Figure 3.
Effect of low glucose (LG) and glucose (G) on endothelin-1 (ET-1) concentration and coronary perfusion pressure (CPP). ET-1 release and CPP were significantly increased in LG as compared to G (P < 0.05). Propofol significantly reduced cardiac ET-1 and CPP in G but not in LG. TMZ facilitated propofol induced reduction in ET-1 and CPP in LG but did not in G. Re-10 is abbreviation of 10 min after reperfusion. Values are presented as mean ± SEM. N = 7 per group. * P < 0.05 versus BS20; # P < 0.05 versus LG; + P < 0.05 versus LG+P.
