Effect of panax quinquefolium fruit saponin on hemodynamics and acute myocardial ischemia in coronary artery ligated dogs / 吉林大学学报(医学版)

Objective To observe the effect of panax quinquefolium fruit saponin(PQFS) on hemodynamics and correlative indexes in the coronary artery ligated dogs.Methods The dogs were divided into five groups randomly(n=6): control group,gingkgo leaf tablet group(24 mg?kg~(-1)),24,12 and 6 mg?kg~(-1) PQFS groups.The myocardial infarction size(MIS)and the changes of the serum enzymes were determined by using the acute myocardial infarction models with the ligation of left anterior descending coronary artery of dogs.The parameters of hemodynamics and myocardial oxygen metabolism were measured in the anesthetic dogs with thoracotomy.(Results Compared) with control group,the myocardial blood flow was increased(P
