  • Title: [Effect of electroacupuncture on nociceptive responses after topical application of bicuculline in the rat].
    Author: Xu W, Yan YS, Chen ZQ.
    Journal: Zhen Ci Yan Jiu; 1989; 14(3):315-8. PubMed ID: 2512019.
    Abstract:
    In this paper effect of EA on nociceptive responses after topical application of bicuculline on the cortical somatosensory area of rats was investigated. Changqiang and Yaoshu point were selected for electroacupuncture. The results showed that the effect of EA on tail flick latency elicited by radiant heat and vocalization threshold elicited by electrical stimulation of tails in rats were increased after topical application of bicuculline on the cortical somatosensory area bilaterally; whereas there were no statistically changes in tail flick latency and vocalization threshold when the drug was applied unilaterally. It suggests that the cerebral cortex is involved in the modulation of nociceptive responses at the level of the brain stem and the spinal cord.
