The purpose of these studies was to determine the role of gracile nucleus and the effects of l-arginine-derived nitric oxide (NO) synthesis in the nucleus on the cardiovascular responses to electroacupuncture (EA) stimulation of "Zusanli" (ST36). Arterial blood pressure and heart rate were monitored during EA stimulation of ST36 following microinjections of(More)
The purpose of these studies was to determine the role of gracile nucleus (Gr) and the effects of L-arginine-derived nitric oxide (NO) synthesis in the nucleus on the cardiovascular responses to somatosympathetic reflexes (SSR). Electrical stimulation of sural and tibial nerve to evoke excitatory and inhibitory SSR was carried out in anesthetized(More)
Recent studies have reported that l-arginine-derived nitric oxide (NO) in the gracile nucleus modifies the hypotensive responses to electroacupuncture (EA) stimulation of Zusanli (ST 36). The purpose of this study was to examine the influence of EA stimulation of ST 36 on neuronal NO synthase (nNOS) expression in the brainstem nuclei in rats. EA stimulation(More)
It has long been accepted that acupuncture, puncturing and scraping needles at certain points on the body, can have analgesic and anesthetic effects, as well as therapeutic effects in the treatment of various diseases. This therapy, including acupuncture anesthesia, has drawn the attention of many investigators and become a research subject of international(More)
The present study was to examine the distribution of transient receptor potential vanilloid type-1 (TRPV1) receptor immunoreactivity in the acupuncture points (acupoint), and determine the influences of electroacupuncture (EA) stimulation on TRPV1 expression. EA stimulation of BL 40 was conducted in two sessions of 20 min separated by an 80 min interval in(More)
These studies examined the influence of 2,5-hexanedione (2,5-HD) intoxication on expression of neuronal nitric oxide synthase (nNOS) in the brainstem nuclei in Zucker Diabetic Fatty (ZDF) vs. lean control (LC) rats. Functional neuropathic changes were also investigated following axonal damage and impaired axonal transport induced by the treatment. Animals(More)
OBJECTIVE The purpose of this study was to determine the effects of electroacupuncture (EA) ST36 on food intake and body weight in obese prone (OP) rats compared to obese resistant (OR) strain on a high fat diet. The influences of EA on mRNA levels of pro-opiomelanocortin (POMC), transient receptor potential vanilloid type-1 (TRPV1), and neuronal nitric(More)
This study was to examine the influence of electroacupuncture (EA) stimulation on neuronal nitric oxide synthase (nNOS) expression in the brainstem nuclei in rats. Low-frequency EA stimulation (3 pulses/sec) was applied between 2 acupuncture points (acupoints), Jinggu (BL 64) and Shugu (BL 65) which are cutaneously located at hindlimb, in rats anesthetized(More)
Neuronal nitric oxide synthase (nNOS) is induced in dorsal root ganglion neurons following axotomy in young rats, and is also increased in the gracile nucleus neurons of intact aged rats. The present study examined the influence of sciatic nerve axotomy on nNOS expression in the gracile nucleus in young compared to aged rats. The unilateral transection of(More)
The annual North American Symposium on Acupuncture is the main scientific part of the educational program in Traditional Chinese Medicine (TCM) established by the Academy of Pain Research in 1979. Dr T. N. Lee, Founder and Director of the Academy and distinguished researcher who proposed the Thalamic Neuron Theory to explain the analgesic effects of(More)
