应用免疫组织化学方法,系统观察性成熟期高白鲑(Coregonus peled)神经系统及性腺中的促性腺激素释放激素(GnRH)的分布情况。结果表明,GnRH在大脑、小脑、中脑、脊髓、延髓中免疫阳性反应明显,且主要分布在神经元内。GnRH免疫阳性细胞在卵巢和精巢中均有分布,而且其阳性部位在卵巢主要分布于小生长期卵母细胞;在精巢中主要分布于间质细胞和精原细胞中。本文讨论了GnRH直接或间接参与高白鲑性腺发育成熟调节的可能性。
Immunocytochemical staining technique was used to study the expression of gonadotropin-releasing hormone (GnRH) in the nervous system and gonad of Coregonus peled. The results showed that there were GnRH immunoreactive endocrine cells in the cerebrum,cerebellum,diencephalon,medulla oblongata,and spinal cord.There were GnRH immunoreactive endocrine cells in the ovary and testis.The positive staining was observed mainly in the small growing oocyte,and in the interstitial cells and spermatogonia.The possible physiological function and morphological evidence of GnRH regulation on the development of gonad in C.peled were discussed.
