【摘要】 本文应用组织学方法对日本海马(Hippocampus japonicus)脑垂体的形态结构和激素分泌细胞的鉴别作了研究。结果表明日本海马脑垂体属前后型。由腺垂体和神经垂体构成。腺垂体分为前腺垂体(RPD),中腺垂体(PPD)和后腺垂体(PI)。用O.F.G染色,腺垂体内可鉴别出七种激素分泌细胞,其中RPD内两种:促肾上腺皮质激素(ACTH)分泌细胞和催乳激素(PRL)分泌细胞;PPD内三种:生长激素(GH)分泌细胞、促甲状腺激素(TSH)分泌细胞和促性腺激素(GTH)分泌细胞;PI内两种:促黑激素(MSH)分泌细胞和一种机能不明的细胞。神经垂体狭窄,长带状位于整个腺垂体的背上方。更多还原

【Abstract】 The present paper investigates the morphological structure of the pituitary gland and the identification of hormone-producing cells of the sea-horse Hippoeampus japonieus by use of histological method. The results showed that the pituitary gland of the sea-horse was of the front and back type, and it was composed of the adenohypophysis and the neurohypbphysis. The adenohypophysis was divided into RPD, PPD and PI. Seven different cell types were identified in the adenohypophysis by O. F. G staining. PRL cells and AC-TH cells were found in RPD; GH cells, TSH cells and GTH cells were found in PPD; and MSH cells and the function cells unknown were found in PI. The neurohypophysis of the sea-horse was narrow and longated occupying the dorsal region of the adenohypophysis.更多还原
