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...

Atypical connections in the formation of the brachial plexus are prevalent and have been reported in different articles. The present report describes a case of variation of the median nerve observed in the Iranian male cadaver during routine trial dissection. There are three roots for median nerve. Median nerve is formed by joining two lateral and medial cords of brachial plexus. Third root ...

objective: to evaluate sensorimotor nerve damage in patients with maxillofacial trauma referring to taleghani hospital, tehran, iran methods: this cross-sectional study was conducted during a 2-year period from 2014 to 2012 in taleghani hospital of tehran. we included a total number of 495 patients with maxillofacial trauma referring to our center during the study period. the demographic inform...

conclusions the study indicated advantages of this modified bier's block compared to the traditional one including ability to perform surgery on upper limb bones and considerable pain relief at surgical and tourniquet sites during the operation until one hour thereafter. results this study showed the presence of analgesia at surgical and tourniquet sites during the operation in 96% of patients,...

the purpose of this study was to investigate magnetic resonance imaging (mri) of the normal feline eyeand optic nerves using t1-weighted and t2-weighted images. a total of 6 healthy female domestic short haircats age 2-2.5 years and weighing 3.2 ± 0.4 kg were selected. magnetic resonance imaging data werecollected using gemsow (philips) at a magnetic field strength of 1.5 t. dorsal, sagittal, a...

The effects of caerulin, a CCK receptor agonist, and proglumide, a receptor antagonist, on hyperalgesia induced by sciatic nerve ligation, was studied in mice. Tolerance to the morphine response was obtained 3,7, 14,21 and 28 days after unilateral sciatic nerve ligation. Maximum hyperalgesia was found 14 days after nerve ligation. Caerulin increased morphine antinociception in nerve-ligated ani...

In microsurgical nerve repair, the epineural sleeve technique can be used to bridge short nerve defects and to coverthe coaptation site with the epineurium of the nerve stump. The epineurium serves as a mechanical aid to reducegap size, and increase repair strength, effectively assisting nerve regeneration.This article presents a 32-year-old patient who experienced complete transection of the m...

Assessment of the peripapillary nerve fiber layer and macular thickness can be determined in ophthalmology using optical coherence tomography (OCT). Decreased nerve fiber layer thickness and macular ganglion cell thickness in optic nerve ischemia have been correlated with visual field loss. OCT allows deep optic nerve head evaluation which helps understand pathophysiology of diseases.  Furtherm...

Autograft is gold standard treatment for peripheral nerve repair up to now. Eggshell membrane (ESM) as nerve guide channel effectively enhances nerve regeneration. Dimethyl sulphoxide (DMSO) has anti-inflammatory and anti-oxidant properties. The aim of this study was to evaluate the effect of DMSO+eggshell membrane guide channel on sciatic nerve regeneration in rats. Thirty two adult male rats ...
