对大鼠的铜喂养研究一般在断奶时开始。这项研究考察了最初体重135克的大鼠连续6周喂食低铜或边际铜水平(0.2或2.5ppm)是否会产生有害影响。对照组饲喂8ppm铜。肝脏铜锌超氧化物歧化酶活性与铜摄入量呈平行关系。无论是低铜摄入量还是边际铜摄入量,血浆铜蓝蛋白活性都很低。低而非边际铜摄入量可导致低体重、高胆固醇、贫血、心肌肥厚、肝脏质膜高度损伤(150μL/kg[ip])。总而言之,低和边际铜摄入量产生低铜酶活性,而低铜摄入量产生病理症状和对氧化应激的抵抗力较差。
Copper feeding studies in rats are generally initiated at weaning. This study examined whether a 6-week feeding of low or marginal Cu levels (0.2 or 2.5 ppm) to rats initially weighing 135 g produced deleterious effects. Controls were fed 8 ppm Cu. Liver Cu-Zn superoxide dismutase activities paralleled Cu intake. Plasma ceruloplasmin activities were very low for both low and marginal Cu consumption. Low but not marginal Cu intake caused a low body weight, high plasma cholesterol level, anemia, cardiac hypertrophy, and a high degree of hepatic plasma membrane injury 24 hours after CCI4injection (150 μL/kg intraperitoneally [IP]). In summary, low and marginal Cu intakes produced low Cu enzyme activities, while low Cu intake produced pathological symptoms and poor resistance to an oxidative stress.
