摘要:

来源于塞尔维亚温泉的热矿水在治疗神经疾病方面已有一个多世纪的历史。这种水富含镁、锂这些矿物质,这些物质可促进中枢神经系统损伤后的神经再生。我们检测了喂饲热矿水对3月龄小鼠损伤脊髓神经再生的影响。结果发现胸段脊髓受压损伤后8和12周,喂饲热矿水小鼠运动功能恢复情况明显好于喂饲标准水小鼠。伤后12周,喂饲热矿水小鼠损伤脊髓儿茶酚胺能神经元轴突出芽情况也明显好于喂饲标准水小鼠,而2组小鼠损伤部位胶质反应则无明显差异。说明热矿水能促进脊髓损伤后的神经再生,但不能减少胶质瘢痕的产生。

Abstract:

Thermomineral water from the Atomic Spa Gornja Trep?a has been used for a century in the treatment of neurologic disease. The thermomineral water contains microelements, including lithium and magnesium, which show neural regeneration-promoting effects after central nervous system injury. In this study, we investigated the effects of oral intake of thermomineral water from the Atomic Spa Gornja Trep?a on nerve regeneration in a 3-month-old mouse model of spinal cord injury. The mice receiving oral intake of thermomineral water showed better locomotor recovery than those without administration of thermomineral water at 8 and 12 weeks after lower thoracic spinal cord compression. At 12 weeks after injury, sprouting of catecholaminergic axons was better in mice that drank thermomineral water than in those without administration of thermomineral water, but there was no difference in glial reaction to injury between mice with and without administration of thermomineral water. These findings suggest that thermomineral water can promote the nerve regeneration but cannot reduce glial scar formation in a mouse model of spinal cord injury.
