附录Ⅳ英文文献及翻译Biological effects of the Magnetic Stimulation on the Toad HeartHongwei Lei,Yuyuan Du,Yina Li,Chunling Liu,Xu Wan2007 IEEE/ICME International Conference on Complex Medical Engineering-CME2007Institute of Biomedical Engineering, Northeastern University, Shenyang, Liaoning 110004, P.R.CHINAAbstract-We stimulated the exposed toad heart by a low frequency and high energy magnetic. By analyze the data of this experiment, it shows that the pulsating of the weak toad heart would make change after stimulated by magnetic. Weak heartbeat strengthened, the single peak curve would become the two peaks curve with atria wave and ventricle wave after the magnetic stimulation. But the cycling of rhythmic pulsatile curve of toad doesnt change.I. INTRODUTIONAll life forms have magnetism. All kinds of magnetic field would have some effects on the configuration and activities of life forms that whichever environmental magnetic, additional magnetic or inside magnetic of organism. The biologic effects are related to the characteristics and the intension of the magnetic field, as well as the species and the tissues of the life forms.The experimentation showed that magnetism stimulation in some range would control the growth of rat tumour, whatever they are in or out the body. Much more they can induce the cancer cells dead.30mT magnetic stimulation would increase the content of NO in the liver and the kidney.Magnetic also can improve the activity of some enzyme and promote the regeneration of nerve tissue.Cell would increase, the bones would be concrescence, the scar would be rehabilitate.The blood rheology and blood cell number both of human and rat would change obviously, DI the blood mucosity would be low.Heart is the most important apparatus of life. It pulsates day and night. Heart once stop pulsating, the life for danger.Numerous scholar pays attention to the role of magnetic field.But they just studied the effects of magnetic stimulation of the heart pacemaker. The experi
