Abstract
  1. The zinc and copper concentration of plasma was determined in rainbow trout, lake trout, walleye and whitefish. 2. These fish had mean plasma zinc concentrations ranging from 9.3 to 15.1 ppm and copper concentrations from 0.6 to 1.3 ppm. 3. In rainbow trout, the concentration of zinc and copper is greater in the erythrocyte membrane than in the total erythrocyte. 4. Ultrafilterable plasma zinc and copper concentration in rainbow trout was determined to be 0.03 and 0.019 ppm, respectively. 5. Dialysis of rainbow trout plasma against 20 mM EDTA results in removal of 99% of the zinc and 88% of the copper from plasma proteins.
摘要
  1. 测定了虹鳟鱼、湖鳟、大眼狮鲈和白鲑血浆中的锌和铜浓度。2. 这些鱼类的血浆锌平均浓度在9.3至15.1 ppm之间,铜浓度在0.6至1.3 ppm之间。3. 在虹鳟鱼中,红细胞膜中的锌和铜浓度高于整个红细胞中的浓度。4. 虹鳟鱼血浆中可超滤的锌和铜浓度分别测定为0.03和0.019 ppm。5. 用20 mM EDTA对虹鳟鱼血浆进行透析,可使血浆蛋白中的锌去除99%,铜去除88%。
