人参总皂甙27mg/kg 静脉注射对大鼠和狗血压先降低后升高,以降压为主,而对狗椎动脉和股动脉血管阻力则降低,且减慢心率。因此心脏前负荷降低,这可能是它抗心肌缺血的原因之一。它还能显著延长小鼠在缺氧条件下的存活时间,并增强耐受低氧环境的能力。它有 ATP 相似的延长缺氧条件下离体豚鼠心房收 Intravenous injection of ginsenoside 27 mg/kg intravenously increased the blood pressure of rats and dogs first and then increased, mainly by reducing blood pressure. However, the vascular resistance of the vertebral artery and femoral artery in dogs decreased, and the heart rate decreased. Therefore, the preload of the heart is reduced, which may be one of the reasons for its anti-myocardial ischemia. It can also significantly prolong the survival of mice under hypoxic conditions and increase their ability to tolerate hypoxic conditions. It has ATP-like prolonged anoxic conditions in isolated guinea pigs
