Abstract: To investigate the influence of magnetized water on the experimental hyperlipemia and atherosclerosis （AS） in rabbits，the rabbits were fed with hypercholesterol food and magnetized water for 90 days，the blood lipid level was detected and the aortic intimate were examined in all rabbits.The results showed that the plasma cholesterol,low-density lipoprotein and triglyceride of the animals feeding with magnetized water were significantly lower than those of the control group，whereas the area of fatty steak and atheromatous plaque were less. It can be concluded that the magnetized water plays role in prevention and treatment of the experimental AS in rabbits.
