摘要
This study established the following groups of rats: a normal group, a sham surgery group, a spinal cord injury model group, a low-frequency electroacupuncture group, a high-frequency electroacupuncture group and a semen coicis group. In all but the normal and sham surgery groups the left half of Tlo was transected. Four hours after model induction, 5-Hz and 100-Hz electroacupuncture were used to stimulate the acupoints I-luantiao (GB 30), Zusan/i (ST 36), Zhiyan9 (DU 9) and Xuanshu (DU 5), or crude extract from semen coicis was intraperitoneally injected, for 8 consecutive weeks. The results indicated that electroacupuncture stimulation and intraperitoneal injection of semen coicis improved the morphology of spinal cord tissue, promoted the recovery of motion-evoked potentials, suppressed glial fibrillary acidic protein expression, and ameliorated motor function in rats with hemisection spinal cord injury. The effects of high-frequency (100 Hz) electroacupuncture ancl semen coicis were significant.
