BACKGROUND The sciatic and peroneal nerves are the most frequently injured in lower extremities, followed by tibial and femoral nerves. The aim of this study is to evaluate the functional results of acute nerve grafting in traumatic sciatic nerve injuries. METHODS A total of 9 patients with sciatic nerve defect were treated with primary nerve grafting. The mean age was 31.7 years. The etiolog...

Neuritin is a new neurotropic factor implicated in nervous system development and plasticity. Studies have shown that Neuritin is upregulated in injured nerves, suggesting that it is involved in nerve repair. To test this hypothesis, we investigated whether recombinant human Neuritin could restore nerve structure and function in a rat model of sciatic nerve injury. Neuritin treatment had a dose...

OBJECTIVE To investigate the effects of electroacupuncture (EA) on mRNA and protein expression of agrin, acetylcholine receptor (AChR)-ε and AChR-γ in a rat model of tibialis anterior muscle atrophy induced by sciatic nerve injection injury, and to examine the underlying mechanism of action. METHODS Fifty-four adult Sprague-Dawley rats were divided into four groups: healthy control group (CON...

There have not been yet enough studies about effects of beta glucan and gliclazide on oxidative stress created by streptozotocin in the brain and sciatic nerve of diabetic rats. The aim of this paper was to investigate the antioxidant effects of gliclazide and beta glucan on oxidative stress and lipid peroxidation created by streptozotosin in brain and sciatic nerve. Total of 42 rats were divid...

The underlying mechanisms of neuropathic pain are poorly understood, and existing treatments are mostly ineffective. We recently demonstrated that antisense mediated "knock-down" of the sodium channel isoform, Na(V)1.8, reverses neuropathic pain behavior after L5/L6 spinal nerve ligation (SNL), implicating a critical functional role of Na(V)1.8 in the neuropathic state. Here we have investigate...

Objective(s): The purpose of this study is to investigate the indication function of the calcium circulation-related factors on the damage to muscle strength and contraction function after nerve injury. The target factors include ryanodine receptor (RyR), inositol-1,4,5-triphosphate receptor (IP3R), phospholamban (PLN), cryptocalcitonin (CASQ), ATPase and troponin C (T...

background and objective: sensory neurons have critical role in improvement of functional outcome of any neuroprotective strategy. the herbal medicine nepeta menthoides has been reported to have anti-apoptotic effect on axotomized spinal motoneurons. in the present study, the putative neuroprotective effect of nepeta menthoides on the axotomized dorsal root ganglion sensory neurons in neonate r...

BACKGROUND Injury to a nerve is the most common reason of acquired peripheral neuropathy. Therefore, searching for effective substance to recover of nerve after injury is need of present era. The current study investigates the protective potential of Standardized Fruit Extract of Punica granatum L (PFE) [Ellagic acid (41.6%), Punicalagins (10%), Granatin (5.1%)] in Tibial & Sural Nerve Transect...
