to evaluate the effects of local administration of the fetal brain extract (fbe) on the crushed peripheral nerve, 15 male wistar rats were used. the right sciatic nerve of 10 rats was locally underwent the tense compression for 30 seconds and then randomly divided into experimental and control (sham) groups. the remained rats were considered as intact animals. treatment was commenced weekly, by...

introduction: arteriovenous fistulas (avf) make chronic hemodialysis easy, but the complications are unpredictable. ischemic neuropathy due to arterial insufficiency is one of the most important complications of avf. this study was designed to evaluate ischemic neuropathy using electro diagnostic method in the extremity carrying fistula. methods: in this cross-sectional study, 37 hemodialysis p...

introduction: the brachial plexus is responsible for the innervation to the upper limb and some parts of the thorax. variations in the branching of the brachial plexus are common and have been reported in 65.3% of the population. the variations (atypical communication) of brachial plexus have significant clinical and surgical importance. methods: in this study 10 upper limbs which belonged to 5...

footdrop is a relatively common deficit among the neurological disorders, which has different causes with various levels of involvement in neuromuscular system, including central nervous system (brain cortex, spinal cord), fifth lumbar root, peripheral nerves and muscles. peroneal nerve injury at the fibular head has been reported to the most common cause of foot drop, which can be due to infar...

conclusions our anesthesia method was sciatic and femoral nerve block under double ultrasonic and nerve stimulator guidance. case presentation in this case report, we present a patient who had tibia and fibula fractures and a symptomatic severe critical aortic stenosis which was diagnosed during a preoperative visit. the patient had exertional dyspnea, palpitations and fainting history, but he ...

excessive scarring; paralleling the process in tendon reconstruction of the hand. inspired by the advantages of the two-stage technique in tendon grafting and with encouraging preliminary results, we aimed to investigate the two-stage nerve grafting technique as an alternative method of secondary nerve repair. methods:  thirty female rats (~200 g) were randomly distributed into two groups (n=15...

conclusions complete rupture of the facial nerve is challenging and the treatment is surgery, which requires careful planning. introduction facial paralysis is a devastating condition with profound functional, aesthetic and psychosocial consequences. tumors within or outside the skull, bell’s palsy and trauma are the most common causes of facial paralysis in adults. case presentation our patien...

peripheral nerve injuries (pni) can lead to lifetime loss of function and disfigurement. different methods such as conventional allograft procedures and using of biological tubes have problems for damaged peripheral nerves reconstruction. designed scaffolds with natural and synthetic materials are now widely used in the reconstruction of damaged tissues. utilization of absorbable and non-absorb...

background: peripheral nerves may be damaged during an injury and its current standard treatment is using an autologous nerve. objectives: the purpose of this experimental study is to evaluate and compare the histological results of nerve regeneration after using the eggshell membrane (esm) guidance channel with autograft. materials and methods: thirty adult male rats were divided into three ex...
