The effects of sympathetic nerve stimulation on the motility of the circular and longitudinal muscle of the large intestine were investigated in vitro , and the involvement of various adrenoceptor subtypes determined. A comparison between the sympathetic supply arising from the prevertebral and pelvic ganglia was also made. In the longitudinal muscle of the distal colon, sympathetic nerve stimulation caused responses which were contractile 0. In the longitudinal muscle of the proximal colon, the effects of sympathetic nerve stimulation were predominantly inhibitory. Some of this inhibition was removed by propranolol 0. This inhibitory response was unchanged by propranolol 0. We conclude that sympathetic nerves innervate adrenoceptors of different types in the various muscle layers and regions of the colon.
Identification of genes associated with pain insensitivity syndromes can increase the understanding of the pathways involved in pain and contribute to the understanding of how sensory pathways relate to other neurological functions. In this report we describe the mapping and identification of the gene responsible for loss of deep pain perception in a large family from northern Sweden.
The loss of pain perception in this family is characterized by impairment in the sensing of deep pain and temperature but with normal mental abilities and with most other neurological responses intact. A severe reduction of unmyelinated nerve fibers and a moderate loss of thin myelinated nerve fibers are observed in the patients. Thus the cases in this study fall into the class of patients with loss of pain perception with underlying peripheral neuropathy.
Using a model of recessive inheritance we identified an 8.

Loss of an important tumor-suppressing gene allows head and neck cancer to spin off signals to nearby nerves, changing their function and recruiting them to the tumor, where they fuel growth and cancer progression, researchers from The University of Texas MD Anderson Cancer Center report in the journal Nature today. By cracking the mechanism that launches neuronal invasion of tumors, a known marker of poor prognosis for patients, the team has uncovered possible avenues to block the process, including the use of drugs commonly used to treat blood pressure and irregular heartbeat.
Co-senior author George Calin, M. The team found that the neurons that invade the tumor are adrenergic nerves, which are involved in stress response. These nerves’ neurotransmitters — adrenaline epinephrine and noradrenaline norepinephrine — are susceptible to drugs known as alpha and beta blockers, long used to treat high blood pressure and irregular heartbeats.
In the study, mice with oral cancer treated with the adrenergic blocker carvedilol had sharply lower tumor growth and cancer cell proliferation. Myers says the team is working to develop clinical trials of adrenergic blockers, most likely in combination with other drugs. Damage to the p53 gene is a major characteristic of head and neck cancers. A tumor-suppressing master transcriptional gene that governs the expression of many other genes, p53 is also mutated in a variety of cancers.
The team found high density of neurons in pdeficient mouse models and human xenograft tumors of oral cavity squamous cell carcinoma OCSCC as well as increased neural growth in clusters of nerves exposed to pdeficient OCSCC. The researchers also discovered that oral cancer communicates with nerves by launching extracellular vesicles — membrane balls that carry various molecules — packed with microRNAs to connect with the nerves. The miRNA cargo varied depending on p53 status of the tumors.

We observed chronological changes of morphology in the dorsal root ganglia in response to pyridoxine toxicity based on cresyl violet staining. The number of large neurons positive for cresyl violet was dramatically decreased after pyridoxine intoxication for 7 days in the dorsal root ganglia and the neuron number was gradually increased after pyridoxine withdrawal. TrkA-immunoreactive neurons were dramatically decreased in the pyridoxine group compared to the control group, but strong TrkA immunoreactivity was observed in the small-sized dorsal root ganglia in this group.

Standards and samples are pipetted into the wells and Beta Nerve Growth Factor present in a sample is bound to the wells by the immobilized antibody. After washing away unbound biotinylated antibody, HRP-conjugated streptavidin is pipetted to the wells. The wells are again washed, a TMB substrate solution is added to the wells and color develops in proportion to the amount of Beta Nerve Growth Factor bound. The Stop Solution changes the color from blue to yellow, and the intensity of the color is measured at nm.
NGFB concentration is very low in normal human serum samples and may be undetectable even with undiluted samples. Optimization may be required with urine samples. Click here to view the general protocols. Publishing research using ab?

Sciatic nerve injuries are often caused by injections, gunshot wounds, lacerations, contusions, compressions, and iatrogenic causes , . Injuries to sciatic nerves cause partial or total loss of motor, sensory and autonomic functions due to the axon discontinuity, degeneration, and eventual death which finally result in substantial functional loss and decreased quality of life , . Functional deficits caused by nerve injuries can be compensated by regeneration of peripheral nerves.
However, clinical and experimental evidences show that the regeneration is usually far more difficult and the results are far from satisfactory, especially after severe injuries , . Numerous therapeutic interventions, mostly pharmacotherapeutic, have been tested to enhance functional recovery after sciatic nerve injuries. The identification of neurotrophic factors offers molecular therapy as a potential approach to enhance nerve regeneration. Among the neurotrophic factors, nerve growth factor NGF plays a critical role.
NGF promotes proliferation and differentiation of neurons, and also modulates the repair of injured nerves , . It has been reported that NGF was upregulated in anticipation of the arrival of a regenerating sprout during the peripheral nerve regeneration . The administration of recombinant NGF protein into injured nerves has been shown to promote nerve repair and enhance functional restoration following nerve damages .

Betaferon is a medicine used to treat adults who have multiple sclerosis MS. MS is a disease in which inflammation damages the protective insulation around nerves demyelination as well as the nerves themselves. Betaferon is used in patients:. Betaferon contains the active substance interferon beta-1b. Betaferon can only be obtained with a prescription and treatment should be started by a doctor who has experience in the treatment of MS. Betaferon is available as a powder and solvent that are made up into a solution that supplies a dose of micrograms.
It is given by injection under the skin. Treatment should start with Patients can inject Betaferon themselves once they have been trained. Betaferon treatment should be stopped in patients whose condition does not improve. For more information about using Betaferon, see the package leaflet or contact your doctor or pharmacist.
The active substance in Betaferon is the protein interferon beta-1b, one of a group of interferons that can be naturally produced by the body to help it fight against viruses and other attacks. The exact way that Betaferon works in MS is not yet known but the active substance , interferon beta-1b, seems to calm down the immune system, and prevents relapses of MS.

Korean Journal of Anesthesiology ;38 4 Sensory loss, muscle weakness, atrophy, and decreased tendon reflexes are more common than pain in neuropathic disease. Recently, Bennett and Xie reported that when the sciatic nerve of a rat is loosely ligated, the rat develops pain syndrome similar to that observed in neuropathic pain states in a human.
Anatomical and physiological studies to date indicate that the major pathological finding in large diameter myelinated fibers distal to the ligatures was a complex loss of response while in small myelinated fibers there were was only subtle changes. However, a more extensive analysis of the various nerve fiber groups in the damaged sciatic nerve is required for a better understanding of the pathophysiology of the present neuropathy.
METHODS To evaluate the damage and regeneration of all caliber of peripheral nerve, we performed an electron microscopic analysis of the sciatic nerve after four loose ligatures were applied. Cross- sectional photomicrographies of regions distal to the ligatures were studied.
