Sciatic nerve shows many variations in its division, especially its high division. This variation (high division of sciatic nerve) may results in sciatica, nerve injury during deep intramuscular injections in gluteal region, piriformis syndrome, and failed sciatic nerve block in anaesthesia. A very unusual case of two different types of high divisions of sciatic nerve on either side of an adult...

Galway, Ireland Adipose Derived Stem Cell Transplantation Does Not Improve Recovery of Motor Function after Sciatic Nerve Transaction in Rats D. Angius, A.M. Knight, R.J. Spinner, M.J. Yaszemski, A. J. Windebank. [email protected] 1 Department of Neurosurgery; 2 Department of Neurobiology; 3 Department of Orthopaedics; Mayo Clinic, Rochester USA Introduction In the peripheral nerve sys...

objectives: crocin and safranal, the major constituents of saffron, exert neuroprotective effects. in the present study, we investigated the effects of crocin and safranal  (alone or in combination with insulin) on peripheral neuropathy in diabetic rats. materials and methods: diabetes was induced by intraperitoneal (i.p.) injection of 60 mg/kg of streptozotocin (stz) and confirmed by blood glu...

AIM To analyze the therapeutic effects of long-term alpha lipoic acid (A-LA) and vitamin B12 use via histomorphometric methods and electron microscopy in the transected sciatic nerves of rats. MATERIAL AND METHODS Forty rats were randomized into five groups (n=8/group). In group I, 1 cm segment of sciatic nerve was resected without any other intervention. In group II (sham), following right s...

AIM To investigate the effects of genistein in a rat model of sciatic nerve crush injury and complete sciatic nerve transection. The effects of genistein were compared with those of gabapentin, which is widely used in clinical practice for peripheral nerve injury. MATERIAL AND METHODS Forty-eight rats were randomly divided into six groups (8 rats in each group): group 1 (sham); group 2, sciat...

temporary paralysis is a rare manifestation of envenoming following the yellow iranian scorpion, odontobuthus doriae (o. doriae). thus, to elucidate the underlying mechanism, we investigated the neurotoxic effect of venom in the sciatic nerve, the possible mechanism in a mice model. the neurotoxicity and temperature effects in the venom-induced neurotoxicity were examined using the mouse sciati...

background peripheral nerve repair is often complicated by fibroblastic scar formation, nerve dysfunction, and traumatic neuroma formation. use of silicone may improve outcomes of these repairs. in this study, we tried to evaluate effectiveness of silicone gel on rats’ sciatic nerve repair, axon regeneration and scar formation around and in the nervous tissues. methods this experimental study w...

Objective: To investigate the efficacy of a type I collagen-derived artificial tubular implant on sciatic nerve regeneration. Materials and Methods: Sprague-Dawley rat sciatic nerve injury model was built by cutting a 5.0 mm defect on the sciatic nerve of the right thigh. Rats with sciatic nerve injury were treated with type I collagen-derived artificial tubular implants (Group A), autologous c...

Recently it has been shown that B-50 is identical to the neuron-specific, growth-associated protein GAP43. The present study reports on the fate of B-50/GAP43 mRNA and B-50/GAP43 protein, determined by radioimmunoassay, in a rat model of peripheral nerve regeneration (sciatic nerve crush) over a period of 37 and 312 d, respectively. Moreover, the effects of repeated subcutaneous injection of th...
