Roles of Adiponectin and Oxidative Stress in the Regulation of Membrane Microviscosity of Red Blood Cells in Hypertensive Men—An Electron Spin Resonance Study

Figure 1

Representative electron spin resonance spectrum of red blood cells (RBCs) for the fatty acid spin-label agent (5-nitroxide stearate). S: order parameter, 2𝑇^′_‖: outer hyperfine splitting, 2𝑇^′_⟂: inner hyperfine splitting, 𝑇_𝑧𝑧 and 𝑇_𝑥𝑥: hyperfine constants, 𝑎_𝑛/𝑎^′_𝑛: isotropic coupling constant, G: gauss. The greater the value of the order parameter (S) was, the lower the membrane fluidity of RBCs was.
