3. discuss
By experiment shows to the anti-inflammatory and antalgic drug effect of pharmaceutical composition of the present invention, this can reach and significantly suppress rat paw edema and dimethylbenzene induced mice auricle edema due to the Ovum Gallus domesticus album, but chronic proliferous type inflammation granuloma induced by implantation of cotton pellets is not had obvious curative effects.Can significantly reduce acetic acid and cause the threshold of pain of turning round body number of times and rising thermic pain mice of mice bitterly.Pain and inflammation that physics and chemical factor are caused have tangible antagonism, and these may be exactly the pharmacodynamics basis of medicine composite for curing gouty arthritis of the present invention.
The gout acute attack is the acute inflammatory reaction that uric acid sodium crystallization (MSUC) causes in joint surrounding tissue deposition.MSUC combines with IgG in the synovial membrane liquid, is engulfed by leukocyte and synovial cell.Impel these cells to discharge histamine, thrombin, complement and arachidonic acid materials such as (AA) immediately, from generating PGE respectively by Cycloxygenase and two approach of lipoxidase
2And leukotriene, the latter stimulates IL-1, IL-6 to produce.All these material short-terms can cause inflammatory reactions such as local vascular dilation, permeability increase, ooze out, edema, leukocyte recruitment, heating.And develop into the peak: add H along with intra-articular pressure increases
+, K
+, 5-HT, Kallidin I, P material, acetylcholine and gland former times class material (ADP:ATP) etc. stimulate periphery affective neuron tip, cause to have an intense pain.
Experimental example 7 pharmaceutical compositions of the present invention are to the side's of tearing open research of antihyperuricemic disease mouse model
1. experiment material and reagent:
1.1 animal: Kunming mouse, male and female half and half, body weight 22-25g is provided by Chengdu University of Traditional Chinese Medicine Animal Experimental Study center, the animal quality certification number: No. 11
1.2 experiment material: medical material is available from five stone medical materials market, Chengdu.Award evaluation by Lu of Chengdu University of Traditional Chinese Medicine elder generation penetrating judgment.Used dosage all calculates with the crude drug amount, is equivalent to 10 times of clinical consumption, and water extract mixes mutually with 95% ethanol extract, and promptly 1g water is carried+1g alcohol extraction=2g crude drug.The positive drug allopurinol is by the excellent magnificent pharmaceutcal corporation, Ltd in Beijing, and lot number U10166 faces with preceding and is made into desired concn with distilled water.Oxonic acid potassium salt (K-oxonate), Aldrich company produces Lot:03510DO-483.Uric acid detection kit (URO-PAP method) Maike Tech Co., Ltd., Sichuan Prov., lot number 1104121;
