摘要：目的：观察禁食豚鼠不同时间心肌姐织Fe.Me.zn、Cu含量的变化，以揭示禁食应激对心肌组织金属元素代谢的影响及规律。方法：短毛种豚鼠24只，随机分为4组，正常组和实验组1、2、3，实验组分别禁食14、48、71小时。结果：(1)心肌组织内Fe、Mg水平随禁食时间的延长而下降。(2)心肌蛆组织中Cu平在禁食48小时48、71小时。结果：(1)心肌组织内Fe、Mg水平随禁食时间的延长而下降。(2)心肌 目的：观察禁食豚鼠不同时间心肌姐织Fe.Me.zn、Cu含量的变化，以揭示禁食应激对心肌组织金属元素代谢的影响及规律。方法：短毛种豚鼠24只，随机分为4组，正常组和实验组1、2、3，实验组分别禁食14、48、71小时。结果：(1)心肌组织内Fe、Mg水平随禁食时间的延长而下降。(2)心肌蛆组织中Cu平在禁食48小时后上升.(3)而Z水平在禁食早期明显上升，以后下降至正常。P均<0．05。结论；禁食应激可影响心肌蛆织内多种金属元素的代谢；心肌组织内Fe、Mg、Zn、CU平与机体应激反应之间存在一定的联系。

Abstract：To study the relatlonship between starvating and the myccardial fe,Mg, Zn, Cu oontents.The effect of starvafing on myocardial Fe. Mg. Zn, Cu eontents in guinea pigs was observed. Method: Twenty-roar guinea pigs were derided randomly into no-starvating group as comparvating, starvating 24hr group.48hr group and 72hrgroup respectively as expermotal group. Results: 1, Myocardial Fe. Mg, Zn and Cu contents lowered along with thecontinunitv of hunger. 2. Cu content increased in experimental groups. 3. Zn oontent increased at the early stage of starvating but decreased to nomal level afterwards, Conclusion;1. Starvaing do effect distribution andmetabolism of myocardial fe,Mg. Zn. Cu, 2. Myocardial Fe. Mg. Zn.Cu contents and stress response may have interelation.
