Background technology
Urticaria is the commonly encountered diseases in a kind of allergic skin disease, shows as the welt skin lesion appearing without definite location, the time time-out disappear, pruritus is immoderate, the complicated difficulty of the cause of disease is sought, and is easy to repeatedly, does not often touchingly heal, and is difficult to radical cure.Be mainly in the women clinically, especially with the young and the middle aged for seeing more.Modern medicine thinks that urticarial pathogenesis is comparatively complicated, so far still for getting clear fully, it is generally acknowledged that most of acute urticarias are the I allergic reaction type.Cause because mastocyte discharges histamine, cause telangiectasis, permeability increases, and plasma protein enters corium in a large number, shows as welt or localized edema clinically.Doctor trained in Western medicine based on antiallergic, does not still have definite curative effect to urticarial treatment.
Skin pruritus is a kind of conscious skin pruritus and do not have the dermatosis of primary lesion, and its pathogeny is not clear so far, and the traditional Chinese medical science thinks to be asthenia of essence and blood, due to the wind syndrome due to blood-deficiency, or be skin blood operation sluggishness, hematogenous blockage, ailment said due to cold or exposure is attacked the people, invades and skin, and is strongly fragrant due to the lung meridian.Can be divided into general skin pruritus and limitation skin pruritus clinically.It is more that the old people suffers from this sick chance.Doctor trained in Western medicine based on antiallergic, does not still have definite curative effect to the treatment of skin pruritus.
Theory of Chinese medical science thinks that dermatosis and ailment said due to cold or exposure are closely related, meets the characteristics of " wind being the primary exopathogen, benefaction and number become ".No matter the patient is because of internal injury caused by excess of seven emotions, the body imbalance of YIN and YANG, and battalion defends and becomes estranged, and weakened defensive QI is felt ailment said due to cold or exposure again and is sent out, or because of the thing of surfeit greasy and surfeit flavour, meat or fish wind symptom, and damp-heat in the spleen and stomach is felt ailment said due to cold or exposure again and is sent out; Or weak usually, deficiency of YIN-blood, the deficiency of YIN is given birth to interior-heat, wind syndrome due to blood-deficiency; Or outbreak repeatedly, QI and blood is consumed, and ailment said due to cold or exposure is attacked and is caused.
There are many doctors to adopt the acute and chronic urticaria of traditional Chinese medical herbal treatment clinically, obtained curative effect preferably.As Feng Xia (" Chinese skin cypridology magazine ", 2004,1:52) with Chinese medicine angelica a decotion of Chinese medicine to be taken cold treatment chronic urticaria 90 examples, wherein 60 examples are organized in treatment, loratadine matched group 30 examples.The treatment group gives Radix Angelicae Sinensis a decotion of Chinese medicine to be taken cold (Radix Angelicae Sinensis, the Radix Polygoni Multiflori, the Radix Paeoniae Alba, Herba Schizonepetae, Radix Saposhnikoviae, the Radix Rehmanniae, Fructus Tribuli, Rhizoma Chuanxiong, the Radix Astragali, Radix Glycyrrhizae) and is decocted in water for oral dose, obey every day 2 times, the oral loratadine tablet 10mg of matched group, inferior every night, took for 4 weeks continuously and carry out efficacy evaluation, treatment group total effective rate is 93.33%, and the matched group total effective rate is 73.33%, two groups of curative effects relatively have statistical significance, P<0.05.Late result compares, i.e. drug withdrawal is after 3 months, and treatment group relapse rate is 22.58%, and matched group is that 61.53%, two group of relapse rate relatively has statistical significance, P<0.05.
Treatment for skin pruritus, the most frequently used method is an external washout with traditional Chinese herbs, as Song Guangying (" Shandong Traditional Chinese Medicine University's journal ", 2004,28 (6): 479) treat 174 routine skin prurituss with embathing the affected part after diffusing (Radix Sophorae Flavescentis, Cortex Phellodendri, Rhizoma Coptidis, Pericarpium Granati, Mahonia fortunei (Lindl.) Fedde, Herba Hieracii Umbellati, the Fructus Kochiae, Radix Sanguisorbae) boiled water immersion of easypro skin, and set up matched group 111 examples to be made into 20: 5000 concentration solution washouts, every day 2 times with lysol and warm water.Skin pruritus shape disappearance person treatment group is 174 examples (100%) in the 10d as a result, and matched group is 78 examples (70.27%).
Though for many years the treatment research of urticaria and skin pruritus is subjected to the attention of Chinese medicine researcher, but the new Chinese medicine that is developed into seldom, and Western medicine is a relief of symptoms, and more untoward reaction is arranged, so still need to be the clinical safe and effective medicine more that provides.The present inventor sums up from clinical experience for many years and constantly weighs, and modification and perfection has been finished the present invention repeatedly.

Experimental example 2: mouse DTH allergy test
Select 60 of 20~22g ICR mices for use, male and female half and half are divided into the blank group at random, model group, and dexamethasone 1.0mg/kg group is for executing the 8.0g/kg group, 4.0g/kg group and 2.0g/kg group, every group of 10 animals.Except that matched group, other animals with 5%2,4-dinitrochlorobenzene acetone soln is applied to abdominal part sensitization, sensitization begins administration on the same day, once a day, continuous 14 days.Sensitization 2 week the back with 1%2,4-dinitrochlorobenzene acetone soln is applied to mouse right ear portion and attacks, and puts to death animal after 24 hours, is the delayed hypersensitivity value with the difference of left and right sides ear weight.The data of surveying through t check comparable group differences.
The result: experimental data shows, through 1%2, after 4-dinitrochlorobenzene acetone soln attacks, two indexs of model group mice auricle swelling degree and thymic weight are compared with the blank group notable difference is all arranged, and the P value distinguishes<0.01 and<0.05, the model establishment.For reagent 8.0g/kg group to 2, the allergy of 4-dinitrochlorobenzene induced mice auricle has obvious inhibitory action, two indexs of swelling degree and thymic weight are compared with model group and all are significant difference, the P value distinguishes<0.05,<0.01 and<0.05; 4.0g/kg and the effect of 2.0g/kg group inhibition mice auricle swelling is not obvious, but thymic weight is all shown good action.

Experimental example 8: acute toxicity testing
Get 40 of ICR kind mices, male and female half and half, after irritating stomach twice in the 128.0g/kg (be equivalent to clinical dosage 150.6 times) a day, continuation through 2 weeks is observed, removing administration group male mice body weight decreases, the significant difference of having compared with the blank group outer (P<0.05), all other indexs there is no unusually, and do not have death.
Experimental example 9: long term toxicity test
Get 80 of SD rats, be divided at random for reagent 64.0g/kg group, 32.0g/kg group, 16.0g/kg group and normal control group, each 10 of every group of male and female by body weight.Every day, gastric infusion was 2 times, continuous 30 days.The oral isopyknic sterilising drinking water of blank group.Write down body weight, food ration weekly once, observe independent activity of animals, fur, feces situation every day.After the administration 1 month, get each 6 animal of male and female at random from every group respectively, get blood through socket of the eye clump vein, the test clotting time, hematological indices, serum biochemistry index, internal organs are weighed and calculate organ index, each organs and tissues is fixed with 10% neutral formalin, paraffin embedding, section, the HE normal dyeing, microscopically carries out histopathologic examination.All the other animals continue to raise for 2 weeks after drug withdrawal, repeat the inspection of above-mentioned project, observe the recovery situation of toxic reaction and have or not the toxic reaction that postpones appearance.
Every physical signs of each administration treated animal does not all occur because of drug-induced toxic reaction.Each internal organs of heavy dose of treated animal there is no the specific tissue form that causes because of dealed with medicine went and change the no significant difference of comparing with matched group.
