摘要:The aim of this paper is to investigate the corticofugal modulation of nucleus periaqueductal gray(PAG) after electroacupuncture by topical administration of GABA on frontal cortex. Experiments were carried out on restrained rabbits immobilized with gallamine. Electrial stimulation of the n. suralis was used as the noxious stimulation. Single unit activites of PAG neurons were record with glass microelectrodes extracellularly."Zusanli" and"Huantiao" points were stimulated by the electroacupuncture bilaterally. GABA was applied topically by means of 3×3mm2 filter paper and placed on the frontal cortex. It was shown that the responses of most PAG neurons evoked by noxious stimulation were inhibited after simple electroacupuncture. On the contrary, the acupuncture effect on PAG neurons was abolished when GABA was administed on frontal cortex. However, the effect of saline control resembled that of simple acupuncture. This result suggested that the corticofugal modulation from frontal cortex may play a role in acupuncture analgesia.

摘要:In this experiment, we established a rat model of EHFV infected by abdominal cavity, and observed the effect of moxibustion on the changes of antigens, antibodies, neural transmitters in blood and tissue on 60 weanling Wistar rats with EHF. The rats were divided into three groups: normal control group (N. group), EHF control group (C.group) and EHF with moxibustion group (M. group) at random. Moxibustion was given at "Shenshu" for 30 minutes daily, 7 days. The 14th day after infection of EHFV, blood and lungs of the rats were fetched. The results obtained are as follows:
