Abstract
Objective To investigate the effects of static magnetic field(SMF) on the viability, adhesion molecule expression of human umbilical vessel endothelial cell. Methods Magnetic flux intensity was 0.1 mT, 1 mT, 10 mT, Cell viability and proliferation were measured with 3H-TdR and MTT methods; and apoptosis of human umbilical vein endothelial cell (HUVEC) was studied by flow cytometry and transmission electric microscopy. ELISA was used to measure the expression of ICAM-1 and VCAM-1 on endothelium. Results 0.1 mT SMF had no effects on the growth of HUVEC, however, SMF of 1 mT, 10 mT attenuated growth of HUVEC. 10 mT static magnetic field could induce apoptosis and necrosis of HUVEC. 10 mT SMF enhanced the expression of ICAM-1 and VCAM-1 on endothelium. Conclusion The effect of SMF depends on the intensity of SMF. 10 mT SMF has adverse effects on human umbilical vessel endothelial cell.
