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...
In a recent preliminary note2 concerning electrical correlates of peripheral nerve injury, it was pointed out that the condition of peripheral nerves is reflected in the changing surface potential differences. The following discussion will briefly describe certain experiments which led to this observation and to the clinical application of the method in cases where there is any question of peri...
A new method of regional anaesthetic called Pericapsular Nerve Group block (PENG) blocks these nerves in order to target the hip's anterior capsule. PENG Block applications include medial thigh lesions, hip fractures, and vascular operations. Only ultrasonic guidance is used when performing Block, two methods—out-of-plane in-plane method—are with low-frequency probe. When employed a multimodal ...
The potential usefulness of chromaffin cells as a source of neuroactive agents for transplantation in the CNS is based on several promising features, including the diversity of biologically active neurotransmitters, neuropeptides and trophic factors produced by the cells. The purpose of this study was to test the possibility that motor as well as sensory dysfunction is reduced by cultured chrom...

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 th...
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 = 18),...
malignant peripheral nerve sheath tumor (mpnst) is a rare nerve sheath tumor derived from schwann cells or pleuripotent cells of neural crest. neurogenic tumors make about 10-20% of all mediastinal tumors. incidence of mpnst is 0.001% in general population and 0.16% in patients with neurofibromatosis i (nf i). we report a case of 60 year female presenting with progressive cough and breathlessne...
Peripheral nerve injury repair is one of the most challenging problems in neurosurgery, partially due to lack of knowledge of three-dimensional (3-D) fine structure and organization of peripheral nerves. In this paper, we explored the structures of nerve fibers in ventral and dorsal nerves with a laser scanning confocal microscopy. Thick tissue staining results suggested that nerve fibers have ...
background: two main muscles studied in the hand for evaluation of median nerve injuries are opponens pollicis (op) and abductor pollicis brevis (apb). however, riché-cannieu communicating branch (rccb) may limit the use of these muscles in electrodiagnosis. this condition is confusing in the case of median nerve injuries. this study was conducted to evaluate the prevalence of rccb. methods: ...
