Ribonucleic acid synthesis in Artemia salina nauplii was strongly inhibited by increasing salinity in the surrounding media, as measured by incorporation of tritiated uridine. Although precursor pools varied in both concentration and specific activity with increasing salinity, these changes did not account for the reduction in ribonucleic acid synthesis. Low levels of oxygen at high salt concentrations did not account for this effect. Intracellular ATP concentrations decreased as the salinity of the environment was increased. Levels of ATP were not affected either by increased oxygen or by the presence of ouabain in the medium.
通过氚标记尿苷掺入量测定，卤虫无节幼体中的核糖核酸合成受到周围介质盐度增加的强烈抑制。尽管随着盐度增加，前体库的浓度和比活性都发生了变化，但这些变化并不能解释核糖核酸合成的减少。高盐浓度下的低氧水平也不能解释这种效应。随着环境盐度的增加，细胞内ATP浓度降低。ATP水平不受氧气增加或培养基中哇巴因存在的影响。
