Abstract
- 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
- 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。
