动物体内磁场与红细胞电泳速度的实验研究

用稀土元素铈（Ｃｅ）、钴（Ｃｏ）等制成磁注射剂（浓度为３００ｇ／Ｌ）作为磁疗新方法，将０．１～０．２ｍｌ（３０～６０ｍｇ）该注射剂注入小鼠股动、静脉周围，并使其在４７５．２Ａ／ｍ电磁场下感应成永磁体，其体表磁场强度为０．０８～０．１６ｍＴ，体内强度为１．２５～１．６ｍＴ。用断尾取血法测定小鼠红细胞电泳速度，结果发现：电泳速度明显增快，与对照组、空白组比较，有非常显著的差异（Ｐ＜０．０１）。提示：弱磁场的生物效应能提高红细胞表面的电荷，使细胞间的排斥力加强，减少红细胞聚集发生的可能性；另一方面，动、静脉血液循环流经磁场时，受磁力线的切割而导致血浆分子结构发生改变，从而使血液粘度降低，血流速度加快。因此，体内磁场可作用于某些疾病，起到活血化瘀、改善微循环的作用。

Experimental Study in Animal's Body with Magnetic Field and Velocity of Erythrocytes Electrophoresis

A experimental study for a new method of the therapy of magnetic field was discribed. It was the magnetic injection which was made of the elements of rare earth cobalt permanent Ce,Co, etc. which was injected into the bodies of mice, injecting 0.1～0.2ml(30～60mg) around the artery and vein of femorals, and then inducting under electromagnetic field 475. 2A/m to make it becoming a permanent magnet. The magnetic field force on the surface of the animal's skin was measured 0.08～0.16mT, cut the animal's skin out, the magnetic field force was 1. 25～1.6mT. According as the technology of the cell electrophoresis,the velocity of erythrocyte was measured and the medium of electrophoresis was 9% cane sugger, mouse's tail was cut off to take the blood for erythrocytes electrophyoresis. Experiments proved that the magnetic injection into the mice bodies when it was inducted a weak magnetic field force. the velocity of red blood cells electrophoresis became faster. Comparison between group experiment and group control, group free. there were very significant difference (P<0.01). The results showed that the biological effect of the weak magnetic field (1. 25￣ 1. 6mT) can raise the suface chargers of the erythrocytes and make the resistance among the red blood cells stronges then the red blood cells will not be easy to aggregate each other. On the other hand, through the blood flows in artery and vein were cut off by magnetic force line to go around and around to make the changes of the structure in blood plasma particles and then the blood viscosity decreased, so that the velocity of blood flow increased.
