本研究在离体工作心模型上比较了天门冬氨酸和谷氨酸强化晶体停搏液保护常温和低温缺血鼠心的效果。 材料和方法 实验分常温和低温两组,各组又分未强化氨基酸停搏液对照组(C)、强化谷氨酸组(G)、强化天门冬氨酸组(A)和谷氨酸和天门冬氨酸联合强化组(A+G)。选择健康雄性慕尼黑Wistar鼠 体重300～ In this study, we compared the protective effect of aspartate and glutamic acid-modified crystalloid cardioplegia against warm and cold ischemic rat hearts in vitro working heart model. Materials and Methods The experiment was divided into two groups at normal temperature and low temperature. The groups were divided into three groups: control group (C), fortified glutamate group (G), fortified aspartate group (A) and glutamic acid Aspartate Intensive Group (A + G). Select healthy male Wistar rats weight of 300 ~
