Methods： Seventy-five Sprauge-Dawley rats were used to establish the models of lumbar intervertebral disk displacement by operation, and divided into five groups including electro-acupuncture group, western medicine group, acupuncture plus medicine group, model group and normal control group, then they were treated with corresponding therapeutic method. The expression of inducible nitric oxide synthase （iNOS） mRNA in the lumbar intervertebral disk tissues of rats was detected by RTPCR. Results： The expression of iNOS mRNA in the lumbar intervertebral disk tissues of rats in model group was compared with that in normal control group, the significant difference was found （P〈 0.01）; While the expressions of iNOS mRNA in the lumbar intervertebral disk tissues of rats in electroacupuncture group, western drug group and acupuncture plus medicine group were all inhibited, and compared with the model group, the significant differences were also found （P 〈 0.01）. Conclusion： Electro-acupuncture could inhibit the expression of iNOS mRNA in the lumbar intervertebral disk tissue.展开更多
