【医】 Leichtenstern's phenomenon
来希敦斯坦氏现象(Lhermitte's sign)是一种神经系统症状,主要表现为颈部过度前屈时,出现从颈部沿脊柱向下放射的短暂性电击样感觉,可能伴随下肢疼痛、肌无力或感觉异常。
核心表现
当患者低头或颈部前屈时,会触发类似“触电”的异常感觉,通常从颈部延伸至背部甚至四肢末端。部分患者可能同时出现下肢反射减退、肌无力等症状。
常见病因
临床意义
该现象并非特定疾病的确诊依据,而是提示脊髓或神经根可能存在病变。需结合MRI、神经电生理检查等进一步明确病因。
若出现此类症状,建议及时就医排查潜在疾病,尤其是伴随肢体麻木、运动障碍时需优先考虑神经系统器质性病变。
来希敦斯坦氏现象(lái xī dūn sī tǎn shì xiàn xiàng)是指在某些低温条件下,水或其他溶液在慢慢冷却时,温度降到了零下但仍然没有结冰,而是变得越来越黏稠。这个现象在科学实验和日常生活中都非常常见。
来希敦斯坦氏现象(lái xī dūn sī tǎn shì xiàn xiàng)
The Laxton's Syndrome refers to the phenomenon that some solutions, such as water, become more and more viscous as they slowly cool down to below freezing point without freezing. This phenomenon is common in both scientific experiments and daily life.
[lækstənz ˈsɪndrəʊm]
The Laxton's Syndrome is a scientific term that describes the phenomenon of certain solutions becoming more viscous as they cool down towards freezing point. It is often used in scientific discussions and research papers as relevant experimental findings.
"The Laxton's Syndrome was observed in the experiment during the cooling of the solution."
“在实验中发现了来希敦斯坦氏现象,即在溶液冷却过程中溶液变得越来越黏稠。”
Supercooled liquids
“超冷液体”
Freezing point
“结冰点”
The term "Laxton's Syndrome" is not a commonly used term in daily English conversation, but it is frequently used in scientific research and discussions related to the properties of solutions.
