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. Concomitantly, the noradrenergic innervation of the myenteric plexus in the large intestine in the rat is less extensive than that in the small intestine Schultzberg et al.

Murine beta-nerve growth factor beta NGF is a amino acid residue polypeptide which, as a functional dimer, plays an important role in the survival and development of certain neuronal populations. The structure of the bis-desocta form of murine beta NGF has been determined in two different crystal modifications using X-ray methods The structure of the bis-desocta form of murine beta NGF has been determined in two different crystal modifications using X-ray methods.

Cytogenetic location: 1p Nerve growth factor is a polypeptide involved in the regulation of growth and differentiation of sympathetic and certain sensory neurons review by Levi-Montalcini, Ullrich et al. NGF consists of 3 types of subunits, alpha, beta and gamma, which specifically interact to form a 7S, ,Da complex.
This complex contains 2 identical amino acid beta-chains, which are solely responsible for nerve growth stimulating activity of NGF. The arrest of dorsal root axonal regeneration at the transitional zone between the peripheral and central nervous system has been repeatedly described. Ramer et al. In adult rats with injured dorsal roots, treatment with NGF, neurotrophin-3 NT3; , or glial cell line-derived neurotrophic factor GDNF; , but not brain-derived neurotrophic factor BDNF; , resulted in selective regrowth of damaged axons across the dorsal root entry zone and into the spinal cord.
Dorsal horn neurons were found to be synaptically driven by peripheral nerve stimulation in rats treated with NGF, NT3, and GDNF, demonstrating functional reconnection.

This follows the publication of ICHD-3 beta in The idea behind the beta version was to promote more field testing before presentation of the final ICHD-3, and this has worked well. There have been excellent field-testing studies published, in migraine with aura, cluster headache, idiopathic intracranial hypertension and trigeminal neuralgia among others.

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 .
