We know: The nerve Ji of embryo of melanin cell traceable, and somebody discovers central nervous system (basically be pineal body) in the corporeal — Mai Latang that existing to restrain melanin to be become all right is peaceful (Melatonin) . Below normal circumstance, it and hypophysis excretive close to melanin (MSH) be in dynamic balance, when Mailatangning is overmuch, can restrain melanin to form. Apparent, the spirit that becomes a person gets malign stimulation, the mood is high-strung, when be being depressed overly, mailatangning is met grow in quantity, bring about wind of white purplish or white patches on the skin thereby.
The wind of nerve sex white purplish or white patches on the skin that causes about nerve element, have a few kinds of point of views at present:
1, nerve section is talked. In clinical on we also observe the leather damage of many patients presses nerve section to distributing, move toward by nerve namely one paragraph comes on, some edge quarrel come mandible, some comes from canthus mandible, some comes by mandible neck. Somebody observes patient of myelitis of a traverse sex, its waist loses a sense below, and of its waist above facial reach the upper part of the body to produce wind of white purplish or white patches on the skin, this makes clear, blaze and local nerve have affinity.
2, all round nerve talking. Somebody has done a test: Choline of second of fade black hormone, adrenalin, adrenalin can make outside body amphibious kind the pigment cell with fish is whiten. Accordingly the person puts forward, melanin cell produces melanin ability to drop, because nerve is chemical all round its,be of corporeal grow in quantity cause, disturbed the active with cheese ammonia enzymatic acid thereby. Below normal circumstance, nerval checks status all round, reason skin pigment does not have a change. But nerve ending function is active all round skin of patient of wind of white purplish or white patches on the skin, increase thereby release the material such as fade black hormone, the ability that brings about melanin cell to synthesize melanin is reduced, come on thereby. Come on thereby..
3, local nerve is talked. Somebody thinks swift as the wind of white purplish or white patches on the skin is injured at local nerve, because all sorts of local stimulation overtax his nerves to cause disease via directly.
4, mechanical stimulation is talked. Face of Yu Yan of good hair of wind of white purplish or white patches on the skin and get attrition share easily (if lumbar Di, brassiere, leather belt, button, hernia is held in the palm,wait for part of press of direct press press) , this likelihood and the skin nerve classics of these place are concerned by long mechanical stimulation.
5, plant nerve is talked. Patients of many wind of white purplish or white patches on the skin often accompany function of classics of fetish having plant disorder, for example blaze place has perspire unusual appearance, spot of hair of companion of wind of white purplish or white patches on the skin is bald the rate that reachs skin nick disease is higher.
