Objective-To evaluate effect of chitosan conduit for peripheral nerve regeneration using sciatic nerve transection model in rat Design- Experimental in vivo study. Animals- Sixty healthy male Wistar rats. Procedures-The rats were divided into four experimental groups (n=15) randomly. In sham group the left sciatic nerve was exposed through a gluteal muscle incision and after careful...
background and aims: neurons are injured under physical, chemical and pathological conditions. the effect of peripheral nervous system injuries may return as retrograde to the cell body of neurons in central nervous system resulting in brain and spinal cord degeneration. because of high content of camphor and borneol, achillea biebersteinii from asteracea family may be effective in prevention t...
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 (200-...
lipomatosis of the nerve, also known as fibrolipomatous hamartoma, is characterized by the infiltration of the nerve by fibro-fatty tissue. the affected nerve becomes thicker, and it simulates a mass lesion. lipomatosis usually affects the median nerve and lipomatosis of the sciatic nerve is extremely rare. magnetic resonance imaging (mri) is the key to diagnosis, and it is usually pathognomoni...
Sciatic nerve is susceptible to trauma and injuries. Animal models for sciatic nerve trauma are mostly in rodents, with limited information about injury-induced neuropathy in non-human primates. We constructed a model of sciatic nerve neuropathy (SNN) in the cynomolgus macaque monkey, Macaca fascicularis, with mild injury to, but without transection of, the sciatic nerve. Monkeys’ behavioral an...
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...
Several studies have demonstrated that L-carnitine exhibits neuroprotective effects on injured sciatic nerve of rats with diabetes mellitus. It is hypothesized that L-carnitine exhibits neuroprotective effects on injured sciatic nerve of rats. Rat sciatic nerve was crush injured by a forceps and exhibited degenerative changes. After intragastric administration of 50 and 100 mg/kg L-carnitine fo...
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...
conclusions coq10 abolished neuropathic pain in cci rats. prevention of cell loss might be attributed to the analgesic effect of coq10. hence, it might be used as a therapeutic intervention for neuropathic pain. background oxidative stress contributes to neuropathic pain. coenzyme q10 (coq10) is used for the treatment of neurodegenerative diseases. however, there is no report regarding the ther...
a b s t r a c tintroduction: peripheral nerve injury is a common disorder and leads to permanent neurological defects. schwann cells have been shown to have nerve repair after being transplanted in peripheral nerve injury. the aim of this study was to determine the beneficial effect of allograft schwann cells on electrophysiological outcome after transection of the sciatic nerve in rats.methods...
