中枢和外周神经递质在激光镇痛过程中的变化规律

Changes of central and peripheral neurotransmitters under laser analgesia

大量的He-Ne激光镇痛的临床实践证明,激光镇痛有较长的镇痛后效应。且要得到良好的激光镇痛效果,需要有一定的激光诱导时间。在激光镇痛的手术中,机体生理功能紊乱较小,而且还有一定的术后抗感染能力。这些特点使我们想到,激光有可能使机体内产生具有镇痛作用的物质,这种物质的生成、积聚和破坏,决定了激光镇痛的发生、发展和消失。为此,我们进行了动物实验,就目前认为与疼痛和镇痛有关的中枢与外周神经递质作一观察,现将结果总结如下。

For the first time the author observed and analyzed the trends of the peripheral neurotransmitters (such as calcinm ion, potassium ion, cholinesterase, serotonin, noradrenaline and dopamine) contained in the blood-stream of horses and catecholaines in the cerebrospinal fluid of equines before and after laser analgesia. Meanwhile the author aiso determined the aeetylcholine contents contained in different parts of the equine brains after laser irradiation.
