The cell model was treated with donepezil or compound Danshen tablets after culture for 72 hours. Reverse transcription-PCR showed that the mRNA expression of amyloid protein precursor decreased in all groups following culture for 24 hours, and that there was no significant difference in the amount of decrease between donepezil and compound Danshen tablets. Our results suggest that compound Danshen tablets can reduce expression of the mRNA for amyloid protein precursor in a transgenic cell model of Alzheimer＇s disease, with similar effects to donepezil.展开更多

[ Method] Tanshinones in Compound Danshen tab- lets were determined by HPLC method. [ Result] A good linear relationship was found in the range of 0.10 -0.50 μg, and the average recovery rate was 100.59% （RSD = 1.38% ）. [ Conclusion] The method is simple, rapid and reproducible, and could be used as a method for quality control of Compound Danshen Tablets.展开更多

Using contact angle tester, the Chinese medicine tablet, a famous Fufang Danshen tablet CP as a model example, was determined by Zisman critical surface tension method. Our study showed that the critical surface tension of Fufang Danshen tablet CP was determined to be 18.00 dyne/cm. The Zisman method, hence, can determine successfully the critical surface tension of Chinese medicine tablet and will become an effective manner to control tablet film coating quality.展开更多
