摘要：

Orientation of normal blood cells in uniform static magnetic fields (8 T maximum) has been investigated microscopically and photometrically. Intact erythrocytes and platelets (intact and fixed) were oriented with their disc planes parallel to the magnetic field because of the diamagnetism of cell membrane components (lipid bilayer and transmembrane proteins), and additionally of microtubule in the case of platelets. In contrast, glutaraldehyde-fixed erythrocytes were oriented perpendicular to the field because of paramagnetism of membrane-bound methemoglobin.
