OBJECTIVE This pilot double-blind randomized study evaluated the efficacy of 780-nm laser phototherapy on the acceleration of axonal growth and regeneration after peripheral nerve reconstruction by polyglycolic acid (PGA) neurotube. BACKGROUND DATA The use of a guiding tube for the reconstruction of segmental loss of injured peripheral nerve has some advantages over the regular nerve grafting...
objective: as effectiveness of the autologous graft in the repair of long nerve defects is very limited an effective substitute is needed. this study was conducted to determine the poled polyvinylidene fluoride (pvdf) tube as an alternative to nerve autograft. materials and methods: the left sciatic nerve was transected in 45 male wistar rats. the animals were then divided randomly into three g...
background: many people suffer from nerve injury. the time consuming nature of the treatments makes the condition worse. therefore, finding a way to accelerate the process of nerve repair is very important. objective: to determine the effect of ultrasound on the acceleration of crushed peripheral nerve regeneration. methods: the experimental model included crushed rat’s sciatic nerve. 40 rats w...
objective(s): to investigate the effect of topical administration of alpha-lipoic acid into chitosan conduit on peripheral nerve regeneration using a rat sciatic nerve transection model. materials and methods: forty five wistar rats were divided into three experimental groups randomly. a 10-mm gap of sciatic nerve was bridged with a chitosan conduit following surgical preparation and anesthesia...
background: olfactory ensheathing glia (oeg) has been shown to have a neuroprotective effect after being transplanted in rats with spinal cord injury. this study was conducted to determine the possible beneficial results of olfactory mucosa transplantation (omt) which is a source of oeg on functional recovery and axonal regeneration after transection of the sciatic nerve. methods: in this study...
Despite promising results observed using silicone rubber chamber, no previous comprehensive work was performed on behavior of the conduit. Present study aimed at further functional, histomorphometrical and immunohistochemical assessment of nerve regeneration in the same animal along a 10-mm rat sciatic nerve gap. Fifty- four male Wistar rats were divided into three experimental groups (n = 1...
The neurotrophin family includes NGF, brain-derived neurotrophic factor (BDNF), neurotrophin-3 (NT-3), and neurotrophin-4 (NT-4). Previous studies have demonstrated that expression of NGF and its low-affinity receptor is induced in nonneuronal cells of the distal segment of the transected sciatic nerve suggesting a role for NGF during axonal regeneration (Johnson, E. M., M. Taniuchi, and P. S. ...
BACKGROUND Peripheral nerve injuries that provoke neuropathic pain are associated with chronic inflammation and nervous lesions. The authors hypothesized that chronic neuropathic pain might be caused by chronic inflammation resulting from a nervous autoimmune reaction triggered by nerve injury. METHODS The authors observed chronic inflammation and neuropathic behaviors for up to 12 weeks afte...
