The peripheral nerve system has an intrinsic regenerative capacity in response to traumatic injury. To better understand the molecular events occurring after peripheral nerve injury, in the current study, a rat model of sciatic nerve crush injury was used. Injured nerves harvested at 0, 1, 4, 7, and 14 days post injury were subjected to deep RNA sequencing for examining global gene expression c...

Background: Neuropathic pain due to damage to the peripheral nerve has influenced millions of people living all over the world. It has been shown that paroxetine can relieve neuropathic pain. Recently, the role of some proteins like BDNF, GABAA receptor, and KCC2 transporter in the occurrence of neuropathic pain has been documented. In the current study, the expression of these proteins affecte...

Posttraumatic nerve repair and prevention of muscle atrophy represent a major challenge of restorative medicine. Considerable interest exists in the potential therapeutic value of laser phototherapy for restoring or temporarily preventing denervated muscle atrophy as well as enhancing regeneration of severely injured peripheral nerves. Low-power laser irradiation (laser phototherapy) was applie...

Peripheral nerve systems are often damaged by crush, compression, ischemia and various diseases. In the sciatic crushed nerve injury, the injured limb displays hyperalgesia, pain-related gait and swelling 1) . These features are abnormal responses to peripheral stimuli and they induce changes of secretion and neural transmission. In peripheral injury, inflammatory reaction by injury induces hyp...

Nerve regeneration is a complex biological phenomenon. In the peripheral nervous system, nerves can regenerate on their own if injuries are small. Larger injuries must be surgically treated, typically with nerve grafts harvested from elsewhere in the body. Spinal cord injury is more complicated, as there are factors in the body that inhibit repair. Unfortunately, a solution to completely repair...

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...
