人参皂甙Rg1干预脊髓损伤模型大鼠转化生长因子β和脑源性神经营养因子的表达
Effect of Ginsenoside Rg1 on transformation growth factor-beta and brain-derived neurotrophic factor expression in spinal cord injury rats
摘要
Abstract
BACKGROUND:Transformation growth factor-β(TGF-β) and brain-derived neurotrophic factor (BDNF) are the main regulatory factors in the process of spinal cord injury. There are many researches for TGF-βand BDNF pathogenesis in the spinal cord injury, but the regulation of Ginsenoside Rg1 intervention on TGF-βand BDNF in the spinal cord injury is rarely reported. <br> OBJECTIVE:To observe the effect of Ginsenoside Rg1 intervention on TGF-βand BDNF expression at themolecular protein levels, and to study the protection effect of Ginsenoside Rg1 on the spinal cord and nerve function after spinal cord injury. <br> METHODS:Experimental rats were randomly divided into blank control group, model group and Ginsenoside Rg1 group. In the model and Ginsenoside Rg1 groups, spinal cord injury model was established with the impact method in rats. In the Ginsenoside Rg1 group, rats were intraperitoneal y injected with 10 mg/kg Ginsenoside Rg1 24 hours after modeling, once per day, for 14 days. Rats in the blank control and model groups were injected with equal saline. <br> RESULTS AND CONCLUSION:Compared with the control group, serum malondialdehyde levels increased, the content of superoxide dismutase decreased, TGF-βexpression levels in spinal cord tissue increased, and BDNF expression levels decreased in the model and Ginsenoside Rg1 groups. Compared with the model group, serum malondialdehyde levels decreased, the content of superoxide dismutase increased, TGF-βexpression levels in spinal cord tissue decreased, and BDNF expression levels increased in the Ginsenoside Rg1 group. Ginsenoside Rg1 can protect the injury spinal cord in rats after spinal cord injury.关键词
