[Optimization of PNS/TGCO components effect on experimental Qi stagnation and blood stasis type of coronary heart disease with increase-decrease baseline geometric proportion design method].

OBJECTIVE

Preliminary exploration of Panax notoginseng saponins (PNS) and total saponins from Cornus officinalis (TGCO) components treatment and characteristics of Qi stagnation and blood stasis type of coronary heart disease.

METHODS

With increase-decrease baseline geometric proportion design method to Optimization of PNS/TGCO components, through observing different proportions effective components effect on mice with pituitrin-induced acute myocardial ischemia and the time of hypoxia tolerance.

RESULTS

Prescriptions 1, 2, 3 and Xuesaitong groups had a certain degree of improvement the role of myocardial ischemia and prescriptions 4, 5, 6, compared with the control group with no significant changes; Prescriptions 3, 4, 5, 6 had a certain role in anti-anoxia in mice, prescriptions 1, 2 and Xuesaitong group, together with the control group with no significant changes.

CONCLUSIONS

Prescription 3 has some effect on improving the role of myocardial ischemia and has a certain role in anti-anoxia. It's the best ratio of PNS/TGCO components for the treatment of Qi stagnation and blood stasis type of coronary heart disease.
