The goal of the present work was to develop minimally invasive imaging techniques to monitor local regeneration of peripheral nerves and to determine the extent of return to function of brain cortical regions associated with that nerve. The sciatic nerve crush model was applied to Sprague-Dawley rats and conventional histological staining for myelin, axons and cell architecture was carried out,...

Infraorbital nerve (ION) transection in neonatal rats leads to disruption of whisker-specific neural patterns (barrelettes), conversion of functional synapses into silent synapses, and reactive gliosis in the brain stem trigeminal principal nucleus (PrV). Here we tested the hypothesis that neonatal peripheral nerve crush injuries permit better functional recovery of associated central nervous s...

Axotomy induces profound morphological changes in the neuronal cell body 2,a,1°. Neurons whose axons lie within the central nervous system of higher vertebrates (intrinsic neurons) show little or no functional regenerative capability 4,8. However, many mammalian neurons whose axons lie outside the CNS, e.g., sensory and motor neuronsS, 15 and some intrinsic CNS neurons of lower vertebrates, suc...

OBJECTIVES To examine the damage location distribution of five main body region injuries of maximum abbreviated injury score (MAIS) 3-6 injured occupants for nearside struck vehicle in front-to-side impact crashes. DESIGN AND SETTING MAIS 3-6 injured occupants information was extracted from the US-National Automotive Sampling System/Crashworthiness Data System in the year 2007; it included th...

The ability of neurites to grow through a lesion and form synaptic connections has been analyzed in a developing mammalian spinal cord in vitro. After isolation of the entire central nervous system (CNS) of the newly born South American opossum (Monodelphis domestica) the spinal cord was crushed. Outgrowth through and beyond the lesion was observed in living preparations for 2-5 days by stainin...

Failed back surgery syndrome (FBSS) is a prevalent, debilitating condition that affects the quality of life of many patients. The role of peridural fibrosis in FBSS continues to be a source of controversy. The authors report an association between peridural fibrosis and tactile allodynia, but not neurological dysfunction in a rodent cauda equine crush injury model. Methods Twenty-one rats were ...

Four weeks after labeling myelin lipids with an intraneural injection of 3H-acetate, sciatic nerves were crushed, and the distribution of radiolabeled myelin lipids was followed by autoradiography from 1 d to 10 weeks later. Just prior to crush, silver grains were localized to the myelin sheath. Three days after crush, axons were degenerating and myelin sheaths were breaking down; silver grains...

PURPOSE Massive earthquakes are harmful to humankind. This study of a historical cohort aimed to investigate the difference between earthquake-related crush thoracic traumas and thoracic traumas unrelated to earthquakes using a multi-detector Computed Tomography (CT). METHODS We retrospectively compared an earthquake-exposed cohort of 215 thoracic trauma crush victims of the Sichuan earthquak...

Sciatic nerve injury is a common disease of peripheral nerve in clinic. After nerve injury, there are many dysfunctions in motoneurons and muscles following regeneration. Previous studies mostly investigated the aspects related to the injured nerve, and the effect on the recurrent inhibition (RI) pathway of spine following regeneration was not fully understood. Following reinnervation after tem...
