title: Model of blood component-heart interaction in cardiac ischemia-reperfusion injury using a Langendorff-based ex vivo assay

description: Supplemental Figure 1: Oxygen supplyand oxygen extraction. Blood gas analyses were performed using KHB and RBCs suspended in KHB with a hematocrit of 40%. Samples were measured before and after perfusion of the murine hearts in the Langendorff Apparatus.Oxygen extraction (DO2) was calculated as the differ of oxygen condtent (cO2) of the samples before and after perfusion of the heart (n=5-7). <br>KHB: Krebs-Henseleit-Buffer; RBC: Red blood cells; Hb: Hemoglobin; sO2: Oxygen saturation; pO2:Oxygen partial preassure. Data are shown asmean and SD. Significances betweengroups are shown (t-test or one-way ANOVA as appropriate). * p&lt;0.05, ** p&lt;0.01, *** p&lt;0.001, **** p&lt;0.0001<br><br>Supplemental Table 1: Raw data of the Langendorff experiments for evaluation of the optimal time of ischemia.
