呋喃二氢吡啶Ⅰ20μmol╱L能使离体兔心局部缺血心肌肌酸磷酸激酶(CPK)和α-羟丁酸脱氢酶(HBD)的释放量明显减少;冠脉阻力下降,流量增加;并能降低血浆及心肌中钙、钠含量,预防缺血性心律失常的发生。提示该药对离体兔心缺血心肌的保护作用,与降低缺血心肌细胞钙、钠含量有关。
Furan dihydropyridine Ⅰ20μmol ╱ L can make isolated heart rabbit myocardial ischemia release of creatine phosphokinase (CPK) and a-hydroxybutyrate dehydrogenase (HBD) significantly reduced coronary resistance decreased flow increased; And can reduce the plasma and myocardial calcium and sodium levels, the prevention of ischemic arrhythmia. Tip of the drug on isolated rabbit heart ischemia myocardial protective effect, and reduce myocardial calcium and sodium content.
