Results: The numbers of Bombesin positive pulmonary cells, the lamina propria S-l00 protein, neuron-specific enolase positive nerve fibers, IgE positive cells, mast cells and IgE positive mast cells significantly increased in bronchiectasis. The changes of pulmonary endocrine cells, nerve fibers and IgE positive cells were more significantly in hyperplastic BALT areas. The S-100 and NSE were found in lymphoid tissue and BALT.

Mast cells and IgE positive cells were seen in the bronchial epithelium and alveolar septa.

In this paper, we first analyze the mechanism of action potential propagated alongan unmyelinated fiber, and present a hypothesis that the velocity of transmembranecurrent is the equivalent of the propagation velocity of action potential. Then usingthe H-H model and the cable equation we obtain the formula of the velocity. Insuccession, we apply a similar method to analyze the mechanism of action potentialpropagated along a myelinated fiber. Using the McNeal model and the CRRSS model,we obtain the formula of the velocity.

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.

The latency of the waves of SEP or MEP is extracted. But it still is the best in all. The control group is the worst of all. The wave can be found again after the spinal cords are hemisectcd in control group. 5..
