PURPOSE: Testosterone (T) treatment accelerates recovery from facial paralysis after facial nerve crush in hamsters. In this study, we extended those studies to another injury model and asked the following question: Will T treatment accelerate recovery from lower limb paralysis following sciatic nerve crush in the rat? METHODS: Castrated adult male rats(More)
Olfactory ensheathing cells (OECs), a unique type of macroglia required for normal olfactory axonal regeneration throughout the lifetime of an individual, have been shown to have regeneration-enhancing properties when used to treat various neuronal injuries. Availability of OECs is a hurdle facing future clinical use of the cells for spinal cord injury(More)
Three isoforms of the alpha subunit of (Na,K)-ATPase have been identified in the rat central nervous system. Using a probe specific for the alpha 1 isoform, mRNA levels were measured from five sections of the rat spinal cord using slot blot techniques. Assigning a value of 1 to the slope obtained from the cervical section, the upper thoracic section was 2.6(More)
The objective of this study was to determine the effect of neurotrophin-secreting Schwann cell implants on the urinary bladder after spinal cord contusion. One hour after severe spinal cord contusion at the T8 to T11 level, carbon filaments containing nonsecreting Schwann cells, brain-derived neurotrophic factor (BDNF)-secreting Schwann cells,(More)
In the present study, we evaluated the ability of carbon filaments to function as ascaffold for the regrowth ofinjured axons in the rat spinal cord. Through different axonal tracing methods, severed spinal axons were observed growing on and between carbon filaments implanted into completely transected rat spinal cords. In addition, somatosensory evoked(More)
In this report intercellular material in developing cartilage and between reaggregating cartilage cells has been examined with lanthanum staining (3, 7, 13, 16) . The proteinpolysaccharides of cartilage have been extensively studied by biochemical methods (2, 8-10, 18-21), and proteinpolysaccharide extracted from cartilage has been shown to precipitate with(More)

One reason that the central nervous system of adult mammals does not regenerate after injury is that neurotrophic factors are present only in low concentrations in these tissues. Recent studies have shown that the application of brain-derived neurotrophic factor (BDNF) and neurotrophin-3 (NT-3) acts to encourage the regrowth of motor and sensory fibers(More)
