【摘要】 目的　观察禁食豚鼠不同时期肝和小肠组织 Fe、Mg、Zn、Cu含量的变化 ,以揭示禁食应激对肝、肠组织金属元素代谢的影响。方法　短毛种豚鼠 2 4只 ,随机分为 4组 ,正常组和实验组 1、2、3,实验组分别禁食 2 4、48、72小时。结果　 1.肝组织内 Fe、Mg和小肠组织中 Fe、Mg、Zn水平随禁食时间的延长而下降。 2 .肝组织中 Zn、Cu水平则随禁食时间的延长而上升。 3.小肠组织内 Cu水平在禁食早期明显上升 ,以后下降至正常。均为 P<0 .0 5。结论　禁食应激可影响消化系统多种金属元素的代谢 ;消化系统内 Fe、Mg、Zn、Cu水平与机体应激反应之间存在一定的联系更多还原

【Abstract】 Objective To study the relationship between starvation and the metal elements in liver and small intestine Method Twenty four guinea pigs were divided randomly into no starving group as comparison, starving 24hr group,48hr group and 72hr group as experimental groups The effect of starvation on Fe,Mg,Zn,Cu levels in liver and small intestine of guinea pigs was observed Results 1 level of Fe,Mg in liver,Fe,Mg,Zn level in small intestine lowered along with the continunity of hunger 2 Zn,Cu level in liver increased in experimental groups 3 Cu level in small intestine increased at the early stage of starvation, decreased to normal level afterwards Conclusion 1 starvation do effect distribution and metabolism of Fe,Mg,Zn,Cu levels in digest system 2 Fe,Mg,Zn,Cu levels in digest system and stress response may have interelation更多还原
