为了了解甲醛对人类坐骨神经的影响,试验采用10%甲醛溶液对中国林蛙坐骨神经进行不同时长刺激,研究甲醛对中国林蛙坐骨神经动作电位的传导速度和绝对不应期的影响。结果表明:甲醛刺激能降低神经干动作电位的传导速度、延长绝对不应期时间;随着刺激时间的延长,甲醛对神经干动作电位传导速度和绝对不应期的影响也随之增加。说明即使较低浓度的甲醛也会造成坐骨神经运动机能的下降,并且这种损伤难以恢复。

In order to understand the effect of formaldehyde on human sciatic nerve, 10% formaldehyde solution was used to stimulate the sciatic nerve of Chinese Rana chensinensis at different times to study the effect of formaldehyde on the conduction velocity and absolute refractory period of the sciatic nerve in Chinese Rana chensinensis. The results showed that formaldehyde could decrease the conduction velocity and prolong the absolute refractory period. With the prolongation of stimulation time, the effect of formalin on the conduction velocity and absolute refractory period also increased. That even a lower concentration of formaldehyde can cause sciatic motor function decline, and this damage is difficult to recover.
