Associations between High-Sensitivity C-Reactive Protein and Membrane Fluidity of Red Blood Cells in Hypertensive Elderly Men: An Electron Spin Resonance Study

Figure 1

Representative electron spin resonance (ESR) spectrum of red blood cells (RBCs) for the fatty acid spin-label agents (5-nitroxide stearate). We calculated the order parameter (S) from outer and inner hyperfine splitting (2T′‖ and 2T′⊥[10–16]). The greater the value of the order parameter (S) was, the lower the membrane fluidity of RBCs was [10–16]. (S: order parameter, 2T′‖: outer hyperfine splitting, 2T′⊥: inner hyperfine splitting, T: tesla.)
