Background: Although peripheral nerves show capacity for regeneration after injury to a certain extent, the extent of regeneration is not remarkable. Previous studies have suggested that through the production of growth factors or extracellular matrix components, mesenchymal stem cells may enhance nerve regeneration.Objectives: In the present study, the therapeutic potenc...

objective: because of the necessity of more effective treatments for the nervous system injuries and considering the role of survivin in cellular proliferation and apoptotic cell death, we have monitored survivin gene expression changes during the course of regeneration in injured sciatic nerves and also l4-l6 segments of spinal cord. materials and methods: we used adult male nmri mice as a mo...

background: peripheral nerves may be damaged during an injury and its current standard treatment is using an autologous nerve. objectives: the purpose of this experimental study is to evaluate and compare the histological results of nerve regeneration after using the eggshell membrane (esm) guidance channel with autograft. materials and methods: thirty adult male rats were divided into three ex...

Objective(s) Motor deficit and neuron degeneration is seen after nerve transection. The aim of this study is to determine whether a poled polyvinelidene fluoride (PVDF) tube with other supportive strategies can protect the neuronal morphology and motor function after sciatic nerve transaction in rats. Materials and Methods After transection of the left sciatic nerve in 60 male Wistar rats (2...

Benign triton tumors (BTT) are very rare lesions composed of mature skeletal muscle and neural tissue. We report a case of a 14-year-old boy who presented with asymptomatic swelling of the chin over an 18-month duration which increased gradually to involve the left side of the lower lip. Clinically, a diagnosis of neurofibroma was made. Excisional biopsy confirmed the diagnosis of a BTT. Having...

introduction: it has been demonstrated that the adrenal medullary transplants into the spinal subarachnoid space can alleviate neuropathic pain behaviors. the aim of the present study was to test the possibility that histological changes of the sciatic nerve in a neuropathic model as well as sensory dysfunction are repaired by adrenal medullary transplantation. material and methods: left sciati...

Background: Neuropathy is one of the important complications of diabetes. Deficiency of the nerve conduction velocity (NCV) that occurs in both human diabetic neuropathy and animal diabetes models is one of the indicators for diabetic neuropathy. In the present study, we examined the effect of enalapril, angiotensinconverting enzyme inhibitor on NCV, number of endoneurial capillaries and th...

background neuropathy is one of the most complications of diabetes that may be associated with changes in the structure and function of the basement membranes in nerves. laminin is one of the most important components of basement membranes in sciatic nerve. objectives in this study, the protective effects of alpha lipoic acid (ala) as an antioxidant agent on blood glucose level, body weight and...

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...
