Auricular electro-stimulation (electroacupuncture) was found to produce naloxone-reversible analgesia in the rat. These behavioral effects were accompanied by significant increases in cerebrospinal fluid (CSF) levels of endorphins with concomitant decreases in the basomedial hypothalamus and medial thalamus of beta-endorphin-like immunoreactivity as well as(More)
The experimental paradigm reported here provides a useful animal model with which to further study the effects of regional electrostimulation and its possible relationship with electrical acupuncture. What similarities there may be between electrical acupuncture and the technique of regional electrocerebral stimulation used for production of electrosleep(More)
BACKGROUND The aim of this study was to investigate the expression of toll-like receptor 2 (TLR2) on cells associated with oral squamous cell carcinoma, epithelial dysplasia and irritative hyperplasia, using immunohistochemistry. RESULTS More immune cells expressed TLR2 in carcinoma and dysplasia than in hyperplasia (P<0.001). No hyperplastic samples(More)
The effects of transcutaneous electrical nerve stimulation (TNS) of a constant alternating current administered at various frequencies and waveforms to volunteer human subjects were investigated. The TNS was found to evoke noncutaneous subjective sensations in all the subjects. Only with a sinusoid waveform of TNS were distinct frequency ranges of the(More)
It was shown that auricular electro-acupuncture in rats, sufficient to induce analgesia, resulted in a significant increase of endorphins in cerebro-spinal fluid with a concomitant decrease in the basomedial hypothalamus and medial thalamus of beta-endorphin-like immunoreactivity as well as endorphin-like radioreceptor activity. In addition, the(More)
