36只断乳大鼠分为三组,以缺维生素D饲料为基础饲料饲养,每组每周补充维生素D_3 0、5000或30000IU/kg,饲养三周,测量大鼠的体重、器官重量并测定血浆及组织锌含量。结果三组动物的体重和组织重量很接近,补充5000IU/kg和30000IU/kg维生素D_3组血浆、肝和肾锌含量明显高于不补充组;补充5000IU/kg维生素D_3组睾丸锌含量明显高于不补充组。前列腺和胫骨锌含量三组之间无明显差异。上述结果表明,维生素D的营养状态对组织锌含量有影响。
Thirty-six weanling rats were divided into three groups and fed on the basis of vitamin D-free diet. Each group was supplemented with vitamin D3, 5000 or 30000 IU / kg weekly for three weeks. The body weight and organ weight of the rats were measured and determined Plasma and tissue zinc content. Results The body weight and tissue weight of the three groups of animals were very similar. The contents of Zn, Zn and Zn in the plasma, liver and kidneys of 5000 IU / kg and 30000 IU / kg vitamin D 3 supplementation groups were significantly higher than those of the non-supplemented groups. The zinc content of testes supplemented with 5000 IU / kg vitamin D 3 group was significantly Do not add group. There was no significant difference between the three groups of prostate and tibia zinc content. The above results show that the nutritional status of vitamin D affect the zinc content of the tissue.
