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...

BACKGROUND The aim of this study was to determine the effects of amniotic membrane impregnated with betamethasone on regeneration of transected sciatic nerve injury in adult albino Wister rats. METHODS In this research, 42 male adult rats were divided into six equal groups. 1) Normal (intact) group: healthy rats without any injury; 2) CONTROL GROUP: sciatic nerve was cut and sutured; 3) Sham ...

the purpose of this experimental study was to evaluate the effect of chicken amniotic fluid (af) on a cross section of rat sciatic nerves. thirty adult male sprague-dawley rats weighing 275 to 300 g, were randomized into three groups treated with (1) amniotic fluid or af (n=10), (2) normal saline or ns (n=10), and (3) sham surgery (n=10). the af was aspirated from the amniotic cavity of incubat...

Striking features of the cellular response to sciatic nerve injury are the proliferation of Schwann cells in the distal nerve stump and the downregulation of myelin-specific gene expression. Once the axons regrow, the Schwann cells differentiate again to reform the myelin sheaths. We have isolated a rat cDNA, SR13, which is strongly downregulated in the initial phase after sciatic nerve injury....

Peripheral nerve blocks are becoming increasingly popular for perioperative use as anesthetics and analgesics in small animals. This prospective study was performed to investigate the duration of motor and sensory blockade following use of bupivacaine for ultrasound-guided femoral and sciatic nerve blocks in dogs and to measure the plasma concentrations of bupivacaine that result from these pro...

OBJECTIVE Present study aimed at further comprehensive functional, histomorphometrical and immunohistochemical assessment of peripheral nerve regeneration using rat sciatic nerve transection model. METHODS The 10-mm rat sciatic nerve gap was created in rats. In control group nerve stumps were sutured to adjacent muscle and in treatment group the gap was bridged using an inside-out vein graft....

BACKGROUND Adding epinephrine to lidocaine solutions for peripheral nerve block potentiates and prolongs the action, but by incompletely understood mechanisms. In an effort to discriminate the pharmacokinetic from the pharmacodynamic effects of epinephrine, the authors measured the lidocaine content of peripheral nerve over the course of block produced by 0.5% lidocaine, with and without epinep...

Wallerian degeneration is an innate immune response which occurs after some kinds of nerve damages such as neurodegenerative disease and acute axonal injury. In clinic, dexamethasone as an anti-inflammatory drug has been used for many years to treat nerve injuries. In present study, we aimed to study the effects of various doses of dexamethasone on the Wallerian degeneration in rat. Twentyseven ...
