background ischemic injury of the spinal cord during the surgical repair of thoracoabdominal aortic aneurysms might lead to paraplegia. although a number of different mechanisms have been proposed, the exact cause of paraplegia has remained unknown, hampering the development of effective pharmacologic or other strategies for prevention of this condition. a number of studies suggested that cyclo...

background: tumors of the central nervous system (cns) are a heterogeneous group of neoplasms with different prevalence in different sex and age groups and various parts of cns. objectives: determining the relative frequency of different types of cns tumors in different ages, sex and cns anatomical locations. materials and methods: this retrospective study was performed using pathological repor...

background: over the years, various types of orthoses have been designed to assist subjects with spinal cord injury (sci) to stand and walk. however, the functional performance of the orthoses has not been adequate, that is, patients experience stability problems, consume excessive energy during ambulation, and generally require assistance in donning and doffing the devices. this research is ai...

background and aim : acute injuries of the spine and spinal cord are causing the greatest amount of disability. they produce high cost outcomes for patients and society psychologically and economically. knowing the epidemiology of these injuries play an important role in planning for prevention and conservative treatment. but now, we have little information about this in our country. the aim of...

Since a significant proportion of diabetic patients have clinical or subclinical neuropathy, there may be concerns about the use of local anaesthetics. The present study was designed to determine and compare the effects of articaine, a widely used anaesthetic in dental practice, and lidocaine on the resting and axonal stimulation-evoked release of [3H]noradrenaline ([3H]NA) in prefrontal cortex...

Intracellular recording and extracellular field potential (FP) recordings were obtained from spinal cord dorsal horn neurons (laminae I-IV) in a rat transverse slice preparation with attached dorsal roots. To study changes in synaptic inputs after neuroma formation, the sciatic nerve was sectioned and ligated 3 weeks before in vitro electrophysiological analysis. Horseradish peroxidase labeling...

Reports of cholecystokinin (CCK) binding and expression of CCK receptors in neonatal rodent spinal cord suggest that CCK may influence neuronal excitability. In patch-clamp recordings from 19/21 ventral horn motoneurons in neonatal (PN 5-12 days) rat spinal cord slices, we noted a slowly rising and prolonged membrane depolarization induced by bath-applied sulfated CCK octapeptide (CCK-8s; 1 mic...

Dourado, Michelle and Peter B. Sargent. Properties of Nicotinic Receptors Underlying Renshaw Cell Excitation by -Motor Neurons in Neonatal Rat Spinal Cord. J Neurophysiol 87: 3117–3125, 2002; 10.1152/jn.00745.2001. We used anatomical and physiological approaches to characterize nicotinic receptors (AChRs) on Renshaw cells of the neonatal rat spinal cord. Confocal imaging of Renshaw cells, ident...
