Study on Improvement Effects of Liqi Sanjie Granule on Liver-qi Stagnation Model Rats / 中国药房

ABSTRACT

OBJECTIVE： To investigate the improvement effects of Liqi sanjie granule on liver-qi stagnation model rats. METHODS： According to the weight， totally 80 rats were randomly divided into blank control group （normal saline）， model control group （normal saline）， Xiaoyao pill control group （positive control a， 750 mg/kg ，calculated by crude drug）， Xiaojin pill control group （positive control b， 200 mg/kg， calculated by pill weight）， Liqi sanjie pill control group （prototype control， 1 957 mg， calculated by crude drug） and Liqi sanjie granule low-dose， medium-dose and high-dose groups （978.5， 1 957， 3 914 mg/kg， calculated by crude drug）， with 10 rats in each group. Each group was given medicine 20 mL/kg intragastrically once a day， for consecutive 21 d. 1 h after per medication， liver-qi stagnation model was established in those groups by binding method except for blank control group. The syrup preference of rats was determined by designing syrup preference test. Rattail suspension test was adopted to determine the hanging immobility time and struggling times of mice. Open-field behavior test was used to determine total behavior score so as to judge the extent of liver-qi stagnation and effect of the drug in rats. RESULTS： Compared with blank control group， hanging immobility time of model control group was significantly prolonged， the syrup preference and the total behavior score of open field test were decreased significantly， with statistical significance （P＜0.05 or P＜0.01）. Compared with model control group， the struggling times of rats were increased significantly in Xiaojin pill control group， Liqi sanjie pill control group and Liqi sanjie granule medium-dose group （P＜0.05 or P＜0.01）； the hanging immobility time of Xiaoyao pill control group， Xiaojin pill control group， Liqi sanjie pill control group， Liqi sanjie granule low-dose and medium-dose groups were shortened significantly； syrup preference and total behavior score of open-field behavior test were increased significantly （P＜0.05 or P＜0.01）. Compared with Liqi sanjie pill control group， the struggling times of rats were decreased significantly and hanging immobility time were prolonged significantly only in Liqi sanjie granule high-dose group （P＜0.05 or P＜0.01）； there was no statistical significance in above indexes of rats in Liqi sanjie granule low-dose and medium-dose groups （P＞0.05）. CONCLUSIONS： Liqi sanjie granule can significantly improve liver-qi stagnation caused by binding method， and the effects of low-dose and medium-dose Liqi sanjie granule are similar to those of Liqi sanjie pill.
