微量元素在动物的生命过程中,具有多种重要的生理功能和作用,不仅参与动物体的代谢、机能调节和生物合成,而且是蛋白质、酶、激素及维生素的构成成分。关于微量元素对人体健康、对动物和植物的生长发育及病理的影响、已有大量报道。本文报道采用原子吸收光谱法,测定新西兰白兔血清中锌、铜、钙、镁、钾、钠等六种主要元素的含量。材料与方法 1.动物来源:选用本中心健康成年(未交配)新西兰白兔,体重2～3公斤,雌雄各半。笼养,喂标准颗粒饲料。 2.器材准备:注射器、试管、容量瓶等,均用蒸馏水和去离子水洗净,烘干,并严格防止灰尘污染。
Trace elements in the life process of animals, has a variety of important physiological functions and roles, not only involved in animal metabolism, function regulation and biosynthesis, but also proteins, enzymes, hormones and vitamins composition. There have been numerous reports on the effects of trace elements on human health, growth and development of animals and plants. In this paper, the content of six main elements of Zinc, Copper, Calcium, Magnesium, Potassium and Sodium in New Zealand white rabbits serum was determined by atomic absorption spectrometry. MATERIALS AND METHODS 1. Animal Origin: The healthy adult (unmated) New Zealand white rabbits of our center were selected and weighed 2 to 3 kg, half male and half female. Caged, fed standard pellets. 2. Equipment Preparation: Syringes, test tubes, volumetric flask, etc., are washed with distilled water and deionized water, drying, and strictly prevent dust pollution.
