Neurosteroids: pregnenolone in human sciatic nerves.
The characterization and quantification of pregnenolone in human sciatic nerves were undertaken, following previous demonstration of the synthesis of this steroid in rat brain oligodendrocytes, to explore the hypothesis that Schwann cells may demonstrate the same biosynthetic activity. Pregnenolone was definitively identified by mass spectrometry and quantified by specific radioimmunoassay. Its...
متن کاملSciatic Functional Index in Smashing Injuries of Rats’ Sciatic Nerves. Evaluation of Method Reproducibility among Examiners
The interpersonal reproducibility of the method for evaluating the Sciatic Functional Index (SFI) was measured by a computer-based program developed for this purpose. Twenty Wistar rats were used, and their right sciatic nerve was addressed using general anesthesia. Those nerves were subsequently smashed in a segment of 5 mm proximal to its trifurcation with a special device, with a fixed load ...
متن کاملtraumatic injury to peripheral nerves.
This article reviews the epidemiology and classification of traumatic peripheral nerve injuries, the effects of these injuries on nerve and muscle, and how electrodiagnosis is used to help classify the injury. Mechanisms of recovery are also reviewed. Motor and sensory nerve conduction studies, needle electromyography, and other electrophysiological methods are particularly useful for localizin...
متن کاملAxonotmesis of the femoral and sciatic nerves mimicking lumbar radiculopathy.
Quant Imaging Med Surg 2015;5(6):932-933 www.amepc.org/qims We report a case describing an extraspinal cause of lumbosacral radiculopathy. The goal of this case report is to highlight the contributing role of magnetic resonance imaging (MRI) of peripheral nerves in radicular pain. Axonotmesis of the sciatic nerve could be considered as a post-traumatic piriformis syndrome. A 53-year-old man pre...
متن کاملRepair of sciatic nerve defects using tissue engineered nerves
In this study, we constructed tissue-engineered nerves with acellular nerve allografts in Sprague-Dawley rats, which were prepared using chemical detergents-enzymatic digestion and mechanical methods, in combination with bone marrow mesenchymal stem cells of Wistar rats cultured in vitro, to repair 15 mm sciatic bone defects in Wistar rats. At postoperative 12 weeks, electrophysiological detect...
