A Brief Analysis of Traditional Chinese Medical Elongated Needle Therapy on Acute Spinal Cord Injury and Its Mechanism
Figure 1
(a) On the 5th day after sham operation, a gray-white boundary of the spinal cord and the nuclei of the neurons were shaped like waves with two sharp peaks; glial cells were scattered; and nuclear Nissl body were clear (HE ×400). (b) On the 1st day after model group operation, the normal structure of the spinal cord tissue was lost; there was hemorrhaging, edema, and necrosis; the boundary between the grey and white matter was unclear; part of the neuronal nuclei decreased; and there was cavity disappearance. Glial cells proliferated, and there was local lymphocytic infiltration (HE ×200). (c) On the 1st day after elongated needle therapy, the normal structure of the spinal cord tissue was lost; there was hemorrhaging, edema, necrosis, and demyelination; the boundary between the grey and white matter was unclear; part of the neuronal nuclei decreased, and gliocytes proliferated around damaged areas (HE ×200). (d) On the 5th day after model group operation, the structure of the spinal cord tissue was disorganized; there was serious karyopyknosis; and a bigger cavity was formed with excessive gliocyte proliferation (HE ×400). (e) On the 5th day after elongated needle therapy, there were still some complete neuronal nuclei. There was a clear boundary between grey and white matter and less gliocyte proliferation (HE ×200).
