ABSTRACT
Objective To investigate the in-vitro antibacterial effect and sterility test of Danshen injection(DI). Methods Three kinds of in-vitro antibacterial and bacteriostatic methods were used to investigate the in-vitro antibacterial effect of DI and to establish its sterility test according to the results of the antibacterial effects. By validation test, the validity of its sterility test was evaluated. Results The results of doubling dilution test showed that the minimum bacteriostatic concentration of DI is 0.098 mg/mL, and its minimum bactericidal concentration is 1. 563 mg/mL in ethanolsulfate medium and 0.195 mg/mL in nutrient meat soup medium. Rate of recovered bacterium was much more than 80% by membrane filtration method. Conclusion DI has strong in-vitro bacteriostatie effects for staphylococcus aureus and the effectual method of its sterility test is membrane filtration method.
ABSTRACT
The effect of Compound Danshen injection (CDI) on anesthetized dog models of myocardial ischemia was investigated. The dog models were established by ligation of main branch of left coronary artery. The results showed that CDI reduced the release of serum CK,LDH and MDA and increased the activity of SOD, decreased the scope of myocardial infarction and slowed down the quickened heart beat induced by ischemia. The differences were significant as compared with those in the model group (P
