摘要

疼痛是生理学和临床上迫切需要解决的难题

创伤又是临床上致病的主要因素之一。本文以截肢造成创伤痛

利用它具有一个发生、发展及转归的自然变化过程

动态观察了创伤引起大鼠尾及伤肢痛阈变化的规Pain threshold of rats was measured by the latent period of tail flick and limd withdrawal elicited by radiant heat. 52male SD rats were used and trauma was produced by aseptic amputation just beneath the right ankle joint. The effect of nerve block and electroacupuncture (EA) was studied and non-traumatic groups were arranged as control. The pain threshold was reduced right after trauma and the lowest level appeared on the 3rd day and then recovered gradually up to the 7th day after trauma. Nerve block and EA markedly raised the pain threshold. Particularly

EA elevated pain threshold of traumatic rats more marked and long-lasted than the effect of nerve block. This may be resulted by mobilizing the functions of the endogenous analgesic systems.
