VASODILATATION, LOWERED PAIN THRESHOLD, AND INCREASED TISSUE VULNERABILITY

摘要: Several observations suggest that neural activity may damage tissues by mechanisms other than those producing ischemia. The phenomenology of herpes zoster, with vasodilation, vesiculation, and necrosis the skin accompanying dorsal ventral horns, was at one time cited as evidence nerve might secondarily cause injury. However, since virus zoster has been demonstrated not only in structures, but also skin, it is uncertain what part nervous system effects play.* occurrence labialis following root section for trigeminal neuralgia supports view alterations function so change environment latent forms they become active.2Thus, about 90% persons who have had near ganglion, including fibers subserving sensation lips, exhibit, a sequel,
