ABSTRACT
The present study aimed to study lipid-lowering effect of seven traditional Chinese medicine monomers in zebrafish system. Zebrafish were fed with high fat diet to establish a hyperlipemia model, then fasted and bathed with seven traditional Chinese medicine monomers stigmasterol, triacontanol, chrysophanol, vanillic acid, shikimic acid, polydatin and oleanolic acid respectively. The oil red O staining was used to detect the blood lipids of zebrafish. Serum total cholesterol and triglyceride levels were detected to validate the lipid-lowering effect. The result showed that a zebrafish model of hyperlipemia could be established by feeding larvae zebrafish with high fat diet. Among the seven traditional Chinese medicine monomers, chrysophanol had lipid-lowering effect. Chrysophanol significantly reduced serum total cholesterol and triglyceride levels in adult zebrafish fed with high fat diet. Chrysophanol accelerated peristalsis frequency of zebrafish intestine and the excretion of high fat food. It is concluded that chrysophanol has lipid- lowering effect in zebrafish, and the mechanism of the effect may be due to the roles of chrysophanol in reducing lipid absorption from gastrointestinal tract and accelerating the excretion of food.

<p><b>OBJECTIVE</b>To study the predominant calcium-antagonist components of Danshen injection.</p><p><b>METHOD</b>The effects of danshensu, protocatechualdehyde and Danshen injection on calcium concentration in cytoplasm of erythrocytes were examined in vitro by the fluorescent Ca+ -chelator fura-2.</p><p><b>RESULT</b>Either DS182 or PCAD can decrease in dose-dependent cytosolic free calcium concentration in human erythrocytes. They had additive effect when mixed, which was similar to Danshen injection.</p><p><b>CONCLUSION</b>DS182 and PCAD may be predominant calcium-antagonist components of Danshen injection.</p>
