Objective : to evaluate the efficiency and safety of partial dopamine re ceptor agonist in clinical application .

目的：评价多巴胺受体部分激动剂临床应用的疗效与安全性。

This is most effective if a specific receptor blocking agent is available to counter the effects of a given agonist .

在这方面最有效的是利用特效的受体阻滞药对抗特定激剂的作用。

Remarkably , functional selectivity can even lead to the exact same molecule acting alternatively as an agonist or antagonist , depending on the physiological response that is being mediated by the protein .

值得注意的是，功能性选择性能引导相同的分子活动，无论刺激物是激动剂还是拮抗剂，因为这取决于由蛋白质调控的生理反应。

Objective : to study the protecting effect of delayed preconditioning with a1 selective adenosine receptor agonist in donor heart preservation .

目的：探讨腺苷a1受体激动剂延迟预处理对大鼠心脏的保护效果。
