Cell death was examined by studying the spinal cords of rats subjected to traumatic insults of mild to moderate severity. Within minutes after mild weight drop impact (a 10 gm weight falling 6.25 mm), neurons in the immediate impact area showed a loss of cytoplasmic Nissl substances. Over the next 7 d, this lesion area expanded and cavitated. Terminal(More)
Schwann cells (SCs) have been shown to be a key element in promoting axonal regeneration after being grafted into the central nervous system (CNS). In the present study, SC-supported axonal regrowth was tested in an adult rat spinal cord implantation model. This model is characterized by a right spinal cord hemisection at the eighth thoracic segment,(More)
Raphe-spinal (R-S) neurons were identified in the nucleus raphe magnus (NRM). The conduction velocity of their axons was calculated to be about 15-60 m/sec. The great majority of R-S neurons did not respond clearly to non-noxious stimuli, such as brushing hair or lightly pressing the skin, but they did respond to noxious stimuli (pricking or clamping), with(More)
Experiments were performed on male rats. The responses of dorsal horn convergent neurons in spinal cord (T12-L1) to noxious stimulation of hind paw were recorded extracellularly with glass microelectrode. When low intensity (2 V) electroacupuncture (EA) was used, the nociceptive responses of convergent neurons were inhibited by EA at "Zusanli" near noxious(More)
Much work has been conducted on the substitutes for Nafion as proton exchange membrane materials. Some researches are focused on the heterogeneous multilayered membranes reported by R. Jiang [J. as the dependence of methanol crossover upon the layer with the lowest permeability, the proton transfer ability is major confined by the layer with the poorest(More)
SmB 6 is a promising candidate material that promises to elucidate the connection between strong correlations and topological electronic states, which is a major challenge in condensed matter physics. The electron correlations are responsible for the development of multiple gaps in SmB 6 , whose elucidation is sorely needed. Here we do so by studying the(More)
Effects of microinjection of vasoactive intestinal peptide (VIP) into cisterna magna, dorsal vagal complex (dorsal motor nucleus of the vagus, nucleus tractus solitarius and area postrema) and spinal subarachnoid space on gastric acid secretion (GAS) were observed in Ghosh-Schild's rats. The results were as follows: (1) VIP (10 micrograms) injected into the(More)
