本文用原位肠道灌流技术，观察了硼对大鼠肠道氟吸收及其对血中微量元素的影响。实验分为对照组（给氟化水）和实验组（给氟硼混合水），结果表明：灌流后氟可经肠道大量吸收，血氟增加；实验组肠道内有ＢＦ—４络合物形成，血氟增加程度明显低于对照组；对照组血中钙、镁含量明显降低，实验组灌流前后微量元素改变无显著意义。说明：硼可与氟在肠道内形成ＢＦ—４，降低肠道氟吸收量，硼可拮抗氟所致的微量元素的降低。
In this paper, in situ intestinal perfusion technique was used to observe the intestinal absorption of boron in rats and its effect on blood trace elements. The experiment was divided into the control group (given fluorinated water) and the experimental group (given fluoroboron mixed water). The results showed that after the perfusion, the fluoride could be absorbed abundantly in the intestinal tract and the blood fluoride increased. In the experimental group, BF-4 complex Formation, blood fluoride increased significantly lower than the control group; the control group, blood calcium and magnesium decreased significantly, the experimental group before and after perfusion of trace elements no significant change. Description: Boron and fluoride in the intestine to form BF-4, reduce intestinal absorption of fluorine, boron can be antagonized fluoride caused by the reduction of trace elements.
