Radioimmune assay has been made of the content of cortisol, insulin, triiodothyronine (T3) and thyroxine (T4) in the blood serum of the dolphin under normal conditions and during 3- ad 6-hour stress. Normal levels of these hormones were found to be equal to 90.34 +/- 6.86 nmol/l, for cortisol, 64.1 +/- 11.1 pmol/l for insulin, 1.27 +/- 0.04 nmol/l for T3 and 138.3 +/- 8.9 nmol/l for T4. Seasonal changes in cortisol level were observed, hormonal concentration being significantly higher during winter and spring as compared to that during summer and autumn. On the whole, the dynamics of hormonal shifts during stress reaction in the dolphin is similar to that in the terrestrial animals reflecting the development of general adaptive syndrome.
对正常状态下以及应激3至6小时的海豚血清中的皮质醇、胰岛素、三碘甲状腺原氨酸（T3）和甲状腺素（T4）含量进行了放射免疫测定。发现这些激素的正常水平分别为：皮质醇90.34±6.86纳摩尔/升，胰岛素64.1±11.1皮摩尔/升，T3 1.27±0.04纳摩尔/升，T4 138.3±8.9纳摩尔/升。观察到皮质醇水平存在季节性变化，冬季和春季的激素浓度明显高于夏季和秋季。总体而言，海豚应激反应期间激素变化的动态与陆地动物相似，反映了一般适应综合征的发展。
