Abstract

The localization of serotonin (5HT) in the rat pineal gland during daylight conditions was investigated by light and electron microscopy using a polyclonal antibody to 5HT and the immunocytochemical method of peroxidase-antiperoxidase (PAP). Thin varicose 5HT fibers were found distributed in the gland at light microscopy level. Ultrastructural observations revealed the presence of terminal endings containing 5HT and localized mainly in the perivascular spaces, labeled with dense diaminobenzidine (DAB) deposits.

采用过氧化物酶-抗过氧化物酶(PAP)免疫细胞化学方法，利用光镜和电镜观察了日光条件下大鼠松果体中5 -羟色胺(5HT)的定位。光镜下可见薄的5HT静脉曲张纤维分布于腺体。超微结构观察显示，存在含有5HT的终末，主要分布在血管周围空间，标记为密集的二氨基苯胺(DAB)沉积。
