Figure 6. Effect of propofol in Intralipid or Intralipid alone on hydrogen peroxide-induced changes in tissue concentrations of creatine phosphate (CrP). Hearts are those in Figure 5. Each value represents mean +/-SEM (n = 8 in each group). **P < 0.01 when compared with value in the Krebs-Henseleit bicarbonate group. ##P < 0.01 when compared with the respective value immediately before hydrogen peroxide infusion (10 min). (double dagger) P < 0.01 when compared with value in the 50-micro Meter propofol group.
