Background technology
Eczema is to have an inflammatory skin disease of obviously oozing out tendency by what multiple internal and external factor caused, is a kind of dermatosis of common pilosity.Its clinical characters is the pleomorphism erythra, and the tendency of oozing out is arranged, and is symmetrically distributed, and chronic phase has soaks into and plumpness, and conscious violent pruritus, the state of an illness can not heal easily repeatedly for many years.Dermatitis, eczema are mentioned together through regular meeting, because they are that the cardinal symptom of dermatitis, eczema is pruritus, erythema to the description of same class disease different angles.But dermatitis, eczema still are distinguishing.Clinical so-called dermatitis is meant that the cause of disease is clear and definite or has the eczema of some feature.The dermatitis majority can be found etiology, as contact dermatitis, and the contacted as article such as paint, metal accessory of premorbid.Yet eczema may temporarily be can not check etiology, in case find the cause of disease, renames as so-and-so dermatitis.The disease of eczema is owing to its sickness rate height, and the course of disease is long in addition, easily outbreak repeatedly, even do not heal all the life (as atopic eczema), thereby the morbidity crowd is very extensive.In addition, various contact dermatitis, allergic dermatitis, seborrheic dermatitis etc. show as subacute and chronic eczema sample dermatitis because of repetitious stimulation also very easily forms eczematization.
According to the course of disease and skin lesion characteristics, eczema generally can be divided into acute, subacute, chronic three classes.Acute eczema: from the beginning of being erythema, connecting erythema then and reach pimple and the herpes that occurs grain of rice size on every side, normal intensive in blocks, the substrate flushing has slight prisoner swollen.Because the affected part itches very much, can grab because of scabies and make the herpes flowing water that breaks, very easily take place rotten to the corn, the incrustation of dry back; If pustule can take place in rotten to the corn postoperative infection, sick damage place, pus can ooze out and with regional glandular enlargement, what have also can merge folliculitis or cyst.Chronic eczema: mostly be acute eczema and show effect repeatedly and transfer chronic eczema to, it is slightly thick to show as pars affecta skin, the dry tack free desquamation, erythema is kermesinus, meet heat or when sleeping pruritus increase the weight of.Because often scratch, scald etc., can there be phenomenons such as redness, flowing water in the affected part.The course of disease is indefinite, and recurrence can prolongedly not healed easily.Subacute eczema: between acute and chronic between, promptly have acute part symptom that chronic performance is also arranged.
Happening part and characteristic according to eczema, be called again: ear eczema, newborn portion eczema, umbilical part eczema, eczema scrotum, anal eczema, hand eczema and legs eczema etc. are called infectious eczematoid dermatitis, infantile eczema and autosensitization dermatitis etc. again by its characteristic.Be found in any age, man, woman all can fall ill asexuality difference.Especially patients with chronic eczema is oozed out erosion, pimple, vesicle, squama, knot is silly or plump, violent pruritus; The course of disease is shown effect very easily repeatedly, and follows paroxysmal very to itch, and makes patient's body and mind feel more painful.The global sickness rate of eczema is up to 20%, and also is not less than 15% in China; Particularly southern area is through moisture with damp and hot, and the eczema sickness rate is higher, accounts for the 15%-25% of department of dermatologry outpatient service amount.
In sum, what eczema was fallen ill extensively has some idea of, thereby this type of patient's local topical is treated, and seems particularly important.The medicine of state's such disease of internal therapy is many at present, and the Therapeutic Principle of subacute stage is antiinflammatory, antipruritic, can select Calamine Lotion, glucocorticoids Emulsion, cream for curing eczema etc. for use; The treatment of chronic phase is absorbed as the master with antipruritic, promotion corium inflammation, can select Pityrol ointment, cream for curing eczema, Eloson ointment, glucocorticoids ointment etc. for use; But it is not good enough according to its curative effect of the equal thoughts of clinical investigation, with the back recurrence is arranged more, can not cure fully, patient has stronger dependency to medicine, very easily recurrence after the drug withdrawal, its reason be since in this class medicine all more or less meeting contain the hormones composition, the glucocorticoid external can reduce capillary permeability, minimizing is oozed out, and antiinflammatory and itching relieving effect are arranged.But the external glucocorticoid can only the short-term medication, and strict restriction consumption, and long-term external glucocorticoid can cause local skin atrophy, telangiectasis, acne and folliculitis etc., therefore, and the unsuitable long-term prescription of face and baby.Long-term a large amount of external glucocorticoid also can cause the general untoward reaction.Therefore the recurrence of the course of disease is unsurmountable problem, also is the critical problem that this disease of eczema heals than refractory.For chronic eczema, the past often helps with compound recipe pine tar ointment or coal tar preparation, because of curative effect limited, and easy pollution clothes, also few using.Some the court's preparations of each hospital, as preparations such as zinc oils, the problems referred to above still fail thoroughly to solve.It is investigated that new result sees, the Chinese medicine for outer use that really is used for the treatment of eczema at present is few, and Cortex Phellodendri ointment, dermatitis curative ointment are only arranged, it is less that the two is used for clinical routine number, do not establish matched group, also do not make toxicological test, only in institute, do the clinic trial stage, also do not declare problem by the new drug requirement.Thus, the external preparation of rare in the market treatment by Chinese herbs eczema.
Because eczema morbidity extensively, annual human and material resources, the financial resources that drop into of country are quite a lot of, and primary disease extremely torments the people, have a strong impact on patient's operate as normal and study.Bring serious harm for patient's physical and mental health. therefore, it is good to research and develop a kind of antipruritic effect, and the skin lesion that disappears is fast, and is difficult for recurrence, and pollution clothes not can be saved the cheap eczema external preparation of natural resources of Chinese medicinal materials again, has very major and immediate significance.
The medicine of pruritus due to mosquito bites is also rare on market.
The specific embodiment
The active selection principle of drug target of the present invention is that the disease characteristics according to foundation dermatitis and eczema class skin injury design drug regimen targetedly.Eczema is a kind of inflammatory skin disease of obviously oozing out tendency that has; And its microorganism recall rate is apparently higher than normal skin, and main bacteria is a staphylococcus aureus, shows that dermatitis and eczema and some antibacterial, fungus, especially staphylococcus aureus are relevant.Therefore we have selected triterpene saponin constituents glycyrrhizic acid or enoxolone or this medicine with higher anti-inflammatory activity of their physiologically acceptable salt in the Radix Glycyrrhizae, be equipped with simultaneously have antiinflammatory, antibacterial, the osthole of itching-relieving action, corter pseudolaricis acetic acid, alkaloid of sophora flavescens ait, obvious at the therapeutic effect of dermatitis and eczema.
