Objectives : The purpose of this study was to investigate the effects of ST36, GB34 and GB39, Hyeopcheok points, electrical acupuncture and acupuncture on nerve regeneration and neuromuscular synaptic reorganization in rat model of spinal cord injury(SCI).
Methods : The subjects were divided into 5 groups; control group with no treatment after inducing SCI, experimental group Ⅰ taken with acupuncture of Hyeopcheok points after inducing SCI, experimental group Ⅱ taken with acupuncture of ST36, GB34 and GB39 after inducing SCI, experimental group Ⅲ taken with electrical acupuncture of Hyeopcheok points after inducing SCI and experimental group Ⅳ taken with electrical acupuncture of ST36, GB34 and GB39 after inducing SCI. After each operation, the present author observed cytological changes, the motor behavior recovery and nerve regeneration by analysis of the motor behavior tests, histological and immunological changes. Rats were tested at modified Tarlov test at the 1st day, Basso, Beattle, Bresnahan locomotor rating scale(BBB scale) at the 3rd, 7th, 14th and 21 days.
Results : 1. Experimental group Ⅳ were improved compared with control group, experimental group Ⅰ, Ⅱ, Ⅲ in the motor behavior test(BBB scale). 2. BDNF(brain-derived neurotrophin factor) expression degree in the SCI tissue of all the experimenral groups were increased compared with control group. Especially, those of experimental group Ⅳ was more effective. 3. Muscular atrophy in gastrocnemius were restored only in experimental group Ⅳ. 4. NT-3(neurotrophin-3) expression degree in the SCI inducing rats of all the experimenral groups were increased compared with control group. Especially, those of experimental group Ⅳ was more effective.
Conclusions : It can be suggested that electrical acupuncture of ST36, GB34 and GB39 may improve motor behavior, histological and immunological findings in SCI-induced rats compared with acupuncture of ST36, GB34 and GB39, acupuncture or electrical acupuncture of Hyeopcheok points.
