Figure 7. Effects of anandamide 100 nM or NCX inhibitor SEA0400 1 µM on [Ca²⁺]_i in ventricular myocytes in simulated ischemic solution.

(A) Transient fluorescence ratios (340∶380) were observed in the single Fura-2-loaded ventricular myocyte in simulated ischemic solution (IS) followed by exposure to anandamide 100 nM. (B) Summary data showing the anandamide and SEA0400 reduced [Ca²⁺]_i partially in simulated ischemic solution. *P<0.05 **P<0.01 vs Control, ^# P<0.05 vs IS, n = 10 in each group.
