Anticoagulation Effect and Bleeding Risk of Combination Therapy with SAFI and Aspirin / 中国药学杂志

OBJECTIVE: To explore the curative effect of combination therapy with salvianolate injection (SAFI) and aspirin on anti-platelet aggregation and blood coagulation function, provide the experimental evidence for clinical consequence use of combination therapy with traditional Chinese medicine and western medicine. METHODS: The bleeding time was measured by cutting tail evaluating of combination of drugs; platelet maximum aggregation rate induced by ADP, AA, collagen and thrombin in rats was determined by absorbance method using a microplate reader; blood coagulation of the four indicators were measured by the semiautomatic blood agglutination instrument. RESULTS: SAFI had nearly no effects on aspirin group's bleeding time. The effect on blood platelets aggregation compared with control group, SAFI group and aspirin group could significantly reduce platelet aggregation induced by ADP, AA, collagen and thrombin in normal rats(P<0.01). Combinative group could significantly increase aspirin group's anti-platelet aggregation induced by ADP, AA, collagen and thrombin in normal rats(P<0.01, P<0.05). Coagulation function SAFI can reduced aspirin group's TT after the combination therapy. CONCLUSION: SAFI can increase anticoagulation effect of aspirin, and have no effect on aspirin's bleeding risk.

Effect of Qishen Yiqi droplet on adenylate contents in myocardium of cor pulmonale rats / 中国中药杂志

Cor pulmonale rat models were induced by a single intraperitoneal injection of monocrotaline(MCT), and the sham group received a single intraperitioneal injection of normal saline. After the model rats received intragastric administration of Qishen Yiqi droplet(QS) for 6 weeks, the contents of adenylate(ATP, ADP and AMP) in right myocardial tissues were measured by HPLC, and then the metabolism changes in myocardium of cor pulmonale rats with QS were investigated. The results showed that ATP, ADP, and AMP were well separated, with a good linearity within a certain range of concentration; and the recovery rates were within the range of 90%-108%. As compared with model group, the level of ATP was significantly elevated in high-dose treatment group; ADP contents showed an increasing trend and AMP contents showed a decreasing trend, indicating that QS could significantly improve energy metabolism system in myocardium. By using the HPLC, a qualitative and quantitative analysis method was given for the determination of ATP, ADP and AMP contents in myocardium, providing a method for energy metabolism measurement in biological samples.
