Studies on statistical properties of spontaneous spike trains of single auditory nerve have shown that the distributing patterns of interval in spike trains represent Poisson distribution. Since Poisson distribution is one of the simplest stochastic processes, previous studies on spontaneous spike trains of single auditory nerve were performed primarily by assuming them as stochastic processes. Recently, further studies on nonlinear dynamic system show that we have not enough evidence to demonstrate the process, whose distribution of probability density is exponential, is Poisson process.

The notable proliferation was not observed by eyes in the local of injection. The infiltration of inflammation cells and mild proliferation of fibrocyte around dura mater was observed by HE stained in 4 and 8 weeks after injection. Infiltration and exudation of inflammation cells was observed by HE stained in epidural nerve root. Compared with group A, no changes of group B, C and D were observed under specific stained. Proliferation of type Ⅱ collagen fibers around dura mater was seen under immunohistochemical stained in 4 and 8 weeks after injection. There is no significant demyelination changes under LFB stained. The thickness and shape of the myelin sheath in epidural nerve root was not regular under transmission electronic microscopy in 4 and 8 weeks after injection. Fibroblast was also seen there. In nerve endometrium, macrophage could be seen under TEM, myelinated nerve fiber changed significantly, but nonmyelinated nerve fiber changed mildly. When 8 weeks, the changes of group D is smaller than the group B and C.

RESULTS: The mild traction group showed angulus anterior individual neuron slightly engorged, neuron and nerve fiber morphous was normal essentially; individual substantia alba demyelinates in fragmentis; medullary sheath and auxiliary fibers of nerve root were hydropsia slightly without conspicuous myelinolysis. The moderate traction group demonstrated myelinolysis change in the spinal cord, and neurofibras lined up chaos, auxiliary fibers disaggregated, neuron dropsy, tigroid body disappeared with karyopycnosis and anachromasis in neurons; nerve root showed myelinolysis. The severe traction group displayed a great demyelination region; anterior motor neurons with karyopycnosis and anachromasis; myelinated nerve fiber of nerve root shrinked, decreased in number, with severe demyelination changes.
