Method： Separate the laboratory rats into Group A （model group, n= 45） and Group B（model ＋ electroacupuncture group, n = 45）. observe injured lumbar nerve tissue with optic microscope and electron microscope and measure the content of PGE2 and 5-HT. Results： Hyperemia around the nerve tissue, edema and nerve root demyelination of electroacupuncture 15 day （Group B） is less than model group 15 day （Group A）. The structure of Schwann cell is normal. Demyelination of electroacupuncture 30 day group （Group B） becomes slight and the nerve edema alleviates. In the Group B, contents of PGE2. and 5-HT after electroacupuncture obviously decrease compared to the Group A. Conclusion： Electroacupuncture can alleviates inflammatory reaction around the injured lumbar nerve and improve the ultra-micro structure of lumbar nerve root.展开更多
