OBJECTIVE：To investigate the “dose-effect-toxicity”correlation of Miao medicine Wikstroemia indica before and after processed on anti-immnue inflammation of mice . METHODS ：Mice were divided into blank group ，model group ，ethanol extract of W. indica raw product groups 1-6，ethanol extract of W. indica processed product by “sweat soaking method ”groups 1-6 （hereinafter called “raw groups 1-6”“processed groups 1-6”for short ，drug dosage were 0.13，0.20，0.26，0.52，1.04，2.6 g/kg）， positive group （cyclophosphamide，36.4 mg/kg），with 10 mice in each group. Except for blank group ，other groups were given 1％ 2，4-dinitrofluorobenzene-acetone-sesame oil mixed solution to induce delayed type hypersensitivity model. After modeling， blank group and model group were given constant volume of 1.0％ CMC-Na solution intragastrically ，and administration groups were given relevant medicine 20 mL/kg intrag astrically，oncea day ，for consecutive 5 d. A fter last medication ，ear swelling degree of mice were recorded ；the inhibition rate of swelling degree， half effective dose （ED50） and 95％ confidence 158-02-32）； interval（CI）of raw and processed products were calculated ； the weight of heart ，liver，spleen，lung and kidney were measured and the indexes of organs were calculated ；ELISA 1161472062@qq.com and modified chemical oxidation method were used to determine the serum levels of inflammatory factors （TNF-α， IL-10） and liver and renal function indexes （ALT，AST， TBIL，BUN，CREA）. RESULTS：Compared with blank group ，the degree of ear swelling in the model group was significantly increased（P＜0.05）. Compared with model group ，ear swelling degree of mice were decreased significantly in different doses groups of ethanol extract of raw and processed products of W. indica （P＜0.05）. The inhibition rate of swelling increased with the increase of dose ，ED50 and 95％CI of delayed hypersensitivity ear swelling were 0.239 6（0.129 0，0.445 2）g/kg and 0.147 3（0.076 8，0.282 7）g/kg，respectively. Compared with blank group ，liver index and serum TNF-α level of mice were increased significantly in model group ，while lung index and serum IL- 10 level were decreased significantly （P＜0.05）. Compared with model group ，the levels of liver indexes （positive group ，raw group 3，processed groups 1-6）and serum TNF-α levels（positive group ，raw groups 1-3，processed groups 1-4） were decreased significantly in different administration groups ；while the levels of lung indexes （positive group ，raw groups 3-6 and processed groups 3-6），serum IL- 10 levels（raw groups 1，2，4 and 5，processed groups 2-6），ALT，AST，BUN and CREA levels （raw groups 4-6），TBIL levels （raw groups 3-6 ）were increased significantly （P＜ 0.05）. CONCLUSIONS ：The ethanol extract of raw product of W. indica has certain anti-inflammatory activity ，and has certain hepatorenal toxicity to mice ，with certain “dose-effect-toxity”correlation. The ethanol ectract of processed product of W. indica has certain anti-inflammatory activity too ，but its hepatorenal toxicity was lower than raw product. The “sweat soaking method ” possesses the function of “retaining efficiency and reducing toxicity ”for processing W. indica .
