CONCLUSION: The fingerprmt can be used to control the ultramicro decoction piece of Radix paeoniae Alba qualities.

Objective To explore relationship between Liver and Spleen of Tradicational Chinse Medicine in T cell activation. Methods The expression of IFN-r and IL-4 of T cells in asthenic spleen qi model and hepatic depression model was detected by RT-PCR. Results IFN-r level of T cells in asthenic spleen qi model significantly decreased, in hepatic depression model significantly increased, in asthenic spleen qi model treated with decoction of four mild drugs rose to normal range, and in hepatic depression model treated with powder of bupleuri dispersing stagnated hepatic qi fell to normal range. The IL-4 level of T cells in asthenic spleen qi model significantly increased, in hepatic depression model significantly decreased, in asthenic spleen qi model treated with decoction of four mild drugs fell to normal range, and in hepatic depression model treated with powder of bupleuri dispersing stagnated hepatic qi rose to normal range. Conclusion Liver and spleen are related to the regulation of THO cells functions.

AIM: To provide a HPLC fingerprint of Fructus aurantii micropowder in order to create a basis for(identification.) METHODS: With the help of computer similarity evaluation,Seventeen kinds of Fructus aruantii sample were pulverized and micronized separately,then were extracted by methanol and compared correlation between both extracts. RESULTS: In methanol extraction,contents of aurantiamarin,hesperidin and neohesperidin in micropowder were more than that in pulverized powders,correlation of both HPLC fingerprint was 0.9~1.0. CONCLUSION: The method established can be used for identifying and evaluating crud drug of Fructus aurantii,and further prove that micronization is beneficial to increasing flavonoid dissolution.

AIM: To provide application and identification basis for methanol-extratis of Fructus aurantii by constructing the HPLC-FP. METHODS: The C_(18) column was used with a mobile phase of(A)(0.095%) phosphoric acid acetonitrile-(B)(0.095%) phosphoric acid gradient elution.The flow rate was(1.0) mL/min.The wavelength of detecter was set at 330 nm.Naringin was reference standard. RESULTS: By cluster analysis,the eighteen kinds of Fructus aurantii samples were classified as four clusters: the superior in producing area,the ordinary in producing area,the ordinary and the inferior.By similarity calculation,the similarity of the superior in producing area and the ordinary in producing area were(0.9)～(1.0),and the ordinary and the inferior were less than(0.9). CONCLUSION: The HPLC-FP of Fructus aurantii has been established.The method can be used to identify and evaluate the quality of Fructus aurantii.

Objective To study the anti-depressant effect of Xiaoyaofang on mice with behavioral despair. Method The mice were given the forced swimming test and tail suspension test to observe the anti-depressant effect of Xiaoyaofang. Result The high dosage of Xi-aoyaofang significantly shortened fast time in the tail suspension test of mice(P < 0.05). And Xiaoyaofang showed the trend of shortening the needed time in the forced swimming test. Conclusion Xiaoyaofang have an anti-depressant effect on mice with behavioral despair.

Objective To investigate the effect of Bu Yang Huan Wu decoction(BYHWD,补阳还五汤) on the expression of basic fibroblast growth factor(bFGF) and its mechanism of anti-cerebral ischemia.Methods Eighty-five Sprague-Dawley rats(body weight 280-300 g) were randomly divided into five groups: normal control group(n=5),sham-operated group,model group(n=20),traditional BYHWD group and ultra-fine powder BYHWD group.Then the latter four groups were further divided into four subgroups of 1,3,5 and 7 days(each n=5).The cerebral ischemic rat model was made by occluding the middle cerebral artery(MCA) with a thread.The traditional decoction and ultra-fine powder decoction groups were ingested with the liquid medicine of BYHWD after 2 hours of the operation(2 ml per rat per day,according to the surface area,it was equivalent to three times the dosage of 70 kg adult(human)).All groups were executed at the 1,3,5 and 7 days after the operation.At the same time there were 5 rats as the normal control group.The brain tissue was taken for the preparation of specimens.The distribution and expression difference of bFGF in the ischemic brain tissues of rats in different groups had been investigated with immuohistochemistry technique.The contents of bFGF in the brain tissue were detected with enzyme linked immunosorbent assay(ELISA).Results The positive expression of bFGF at peri-infarct area after ischemia increased obviously,but at central-infarct area there was less such positive expression.There was no expression at contra-lateral side to the ischemic area.The expression of bFGF immune positive cell increased at 1 day,peaked at 3 days,and returned to baseline at 7 days.The positive cells of bFGF in tradition decoction and ultra-fine powder decoction groups were obviously more than those in the model group at 3,5 and 7 days(all P

Objective: To optimize the formulation of Ketanning dispersible tablet.Methods: The Ketanning dispersible tablet was prepared by using wet granules.The formulation and preparation technology was optimized by using orthogonal design which took the situation of granules,appearance of taablets,the disintegrating time and the tensile strength as indices.Results: The optimized formulation contained,10%MCC,10% PVPP is inner,10% PVPP is outer,1% magnesium stearate.The tensile strength,the disintegrating time were 70N and 3min respectively.Conclusion: It is successful to prepare immediate release tablet.The optimized formulation is rational and stable,the tablet could be released quickly.
