In previous studies using Fos expression as a marker of neuronal activation, we showed that nitrous oxide (N(2)O) activates bulbospinal noradrenergic neurons in rats and that destruction of these neuronal pathways leads to loss of N(2)O antinociceptive action. Based on previous rat studies it has been proposed that these noradrenergic neurons are activated through opioid receptors through the release of endogenous opioid ligands in the periaqueductal gray.

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 agents into gracile nucleus. EA ST36 produced depressor and bradycardiac responses in anesthetized Sprague-Dawley rats.

It has been reported that intracerebroventricular injection of a μ receptor antagonist blocked 2 but not 100Hz electroacupuncture (EA)-produced analgesia in an uninjured animal model. Because persistent pain changes neural response to external stimulation, we hypothesized that the mechanisms of EA anti-hyperalgesia may be different in persistent pain than in health. Hyperalgesia, decreased paw withdrawal latency (PWL) to a noxious thermal stimulus, was induced by subcutaneously injecting complete Freund's adjuvant (CFA) into the hind paws of rats.

PURPOSE: Infrared heat, a transient receptor potential vanilloid type-3 (TRPV3) sensitive stimulus, may have potential physiological effects beneficial to treating metabolic syndrome. MATERIALS AND METHODS: Obesity prone (OP) and obesity resistant (OR) rats were fed for seven days on a high-fat diet. Heat treated OP rats were exposed twice daily to infrared light for 20 min each, separated by 80 min of rest. Food intake, blood pressure, blood glucose, and body weight measurements were taken daily and compared between treated OP rats, untreated OP rats, and OR controls.

In order to assess the direct connections of the C2 Dorsal Root Ganglion, the right ganglion in each of three Macaca Irus Monkeys was injected with labelled 3H-leucine. After survival times of 24 hours and autoradiographic techniques, the slides were read using light and dark field microscopes and mapped onto enlarged cross sectional drawings. Results show labelling into the lateral cervical nucleus, the central cervical nucleus and caudal to C5 of the spinal cord.

Reported is a case of a 39-year-old man with medial medullary infarction following chiropractic neck manipulation. Neurologically, he showed right hemiparesis sparing the face, right deep sensory impairment and tongue deviation to the left in five hours after neck manipulation. A cranial MRI revealed an ischemic lesion in the left medial portion of the medulla oblongata. Cerebral angiography demonstrated no apparent organic lesion of the right vertebral artery (VA), but showed hypoplasia of the left VA.

A-38-year-old man suddenly developed nausea, vomiting and vertigo during chiropractic neck manipulation. This was followed by right hemiplegia, right deep sensory disturbance and left hypoglossal nerve palsy, consistent with the medial medullary infarction (Dejerine syndrome). The MRI revealed infarction at left medial part of the medulla. The vertebral angiogram and MRA showed marked narrowing of the left vertebral artery. X-rays of the cervical spine showed no spondylosis, dislocation nor osteolysis of the odontoid process.
