What is measles
summary
Fengtuan, also known as urticaria, has huge physiological and pathological characteristics. If you know it well, you can find out the key points to control the disease. The generation of fengtuan has a huge potential. The mechanism can be divided into two types: abnormal response and non abnormal response. The wheal tension caused by abnormal response is I-type abnormal response. Its antibody is IgE, which adsorbs on the appearance of mast cells (or basophils). When the antigen decided to eat or suck people again into the body and antibody joint, produce antigen antibody response. It can activate the appearance receptor of mast cells, lead to degranulation of mast cells and release chemical mediators such as histamine, kinin and eosinophil chemokines. These substances make the skin microvascular dilation and congestion, increase the infiltration and exudation of the wall of the tube, and produce the air mass of plasma extravasation. What's measles? Let's talk about it.
What is measles
First: type II and type III abnormal response, IgE antibody is not added. Antibody IgG, IgM or immune complex. We decided to activate complement and make mast cells release histamine in the presence of C3 or C5. Non arrhythmic response is the release of histone by some substances, such as chemical histamine releasers (morphine, codeine, antibiotics, vitamin BL, etc.) to lower the level of cyclic adenosine monophosphate in mast cells. Light, heat, cold, mechanical stimulation and other factors can also directly cause mast cells degranulation and release histamine. Activity, drinking and mental emergency can make cholinergic nerve endings produce acetylcholine. It can induce the increase of guanxi cyclophosphate in mast cells and promote mast cells to release histamine. Acetylcholine or due to internal excretion factors can also directly cause skin small blood vessels dilation, increased permeability and produce wheal.
Second: oral and external use. First, internal use of anti structural amine drugs is the treatment of various urticaria patients tension drugs, can control the symptoms of most patients; second, local use of calamine lotion or zinc oxide lotion can achieve temporary curative effect.
Third: Traditional Chinese medicine treatment, traditional Chinese medicine treatment of urticaria has obvious effect. The wind heat type of acute urticaria was treated with Jingfang decoction, and the wind cold type was treated with maguigeban decoction. For papular urticaria, Jingfang decoction was used to treat it, while for chronic urticaria, acute urticaria, the same as acute urticaria; for patients with delayed course, Huoxue Huayu, Jianpi Qushi, Wenzhong Bushen and syndrome differentiation were used. The patients with heat should be treated with Qingre Kuanxiong decoction, the patients with wind cold should be treated with Yong'an Zhiyang prescription, the patients with spleen deficiency should be treated with Weiling decoction, Renshen Jianpi pill, and the patients with kidney yang deficiency should be treated with Jingui Shenqi Pill.
matters needing attention
The family attribute cold measles, hereditary vascular edema, pigmented measles. Prurigo gravidarum and dermatitis ulcerosa. With the growth of society, people are living in an increasingly developed society. More and more medical factors are absorbed from physical and chemical factors, so the probability of getting urticaria is much higher.
