Abstract
  1. Rainbow trout exposed to seawater or 20 ppm zinc showed hypersecretion of mucus whose sialic acid (N-acetylneuraminic acid) content 0.192 micro M g-1 mucus was not significantly different to that produced by trout in freshwater, 0.184 micro M g-1 mucus. 2. Measurement of sialic content in the water indicated its production (and therefore mucus production) was about 70 times higher in seawater and 20 ppm zinc compared to freshwater production.
摘要
  1. 暴露于海水或20 ppm锌中的虹鳟鱼会出现黏液分泌过多的情况,其黏液中唾液酸(N-乙酰神经氨酸)含量为0.192微摩尔/克黏液,与淡水中虹鳟鱼产生的黏液(0.184微摩尔/克黏液)相比,并无显著差异。2. 对水中唾液酸含量的测量表明,与淡水环境相比,海水和20 ppm锌环境中唾液酸的产生量(进而黏液的产生量)高出约70倍。
