Abstract

The presence of steroids was investigated by radioimmunoassay - mass spectrometry in serum and homogenates of gonads and presumed adrenocortical (pro- and opisthonephric) tissue of larval and mature brook lampreys (Lampetra planeri Bloch) of both sexes. Pregnenolone was detected in all tissue samples studied whereas androstenedione could be identified only in presumed adrenocortical tissue from male and female mature animals as well as in testis. Testosterone was present in testis of adult lampreys and in sera of larval and adult animals.

摘要

采用放射免疫分析法-质谱分析法对雌雄幼体和成体溪七鳃鳗（Lampetra planeri Bloch）的血清、性腺匀浆以及假定的肾上腺皮质（前肾和后肾）组织中的类固醇进行了检测。在所研究的所有组织样本中均检测到了孕烯醇酮，而仅在雌雄成体动物的假定肾上腺皮质组织以及睾丸中鉴定出了雄烯二酮。睾酮存在于成年七鳃鳗的睾丸以及幼体和成体动物的血清中。
