Two groups of cells (light and dark) were found in the interrenal gland of the young beluga from the fresh-water. Ultrastructural differencies are presumably associated with different functional activity of cells. 12 hours after the transfer of fishes to the sea water, the interrenal cells appeared to be most active with significant elevation of volumetric density of mitochondria and endoplasmic reticulum. After 8 days in the sea water, dark cells were found seldom; a great number of small lyposomes and large myelin-like figures were observed in the cytoplasm of the light cells. The volumetric density of mitochondria and of the reticulum was seen decreased. The functional activity of interrenal gland of the young beluga was lower after 8 days than after 12 hours in the sea water, but higher than in the fresh-water.
在来自淡水的幼年白鲸的肾上腺中发现了两组细胞（浅色和深色）。超微结构差异可能与细胞的不同功能活性有关。将鱼转移到海水中12小时后，肾上腺细胞似乎最为活跃，线粒体和内质网的体积密度显著升高。在海水中8天后，很少发现深色细胞；在浅色细胞的细胞质中观察到大量小脂体和大的髓鞘样结构。线粒体和内质网的体积密度下降。幼年白鲸的肾上腺在海水中8天后的功能活性低于12小时后的，但高于在淡水中的。
