摘要： 采用H.E染色法、Mallory染色法、Heidenhain-Azan(简称HA)法、鱼类脑垂体染色法(简称Jafri)及电镜技术对雌性条斑星鲽Verasper moseri的脑垂体进行了组织学和超微结构的研究, 探讨了促性腺激素分泌细胞与性腺发育的关系。结果表明, 雌性条斑星鲽脑垂体呈背腹型, 由神经垂体和腺垂体两部分组成。神经垂体为一束神经纤维, 中间夹杂两种垂体细胞和两种胶质。腺垂体结构复杂, 分为前腺垂体(RPD)、中腺垂体(PPD)和后腺垂体(PI), 腺垂体内鉴别出6种内分泌细胞。前腺垂体内有3种: 催乳激素(PROL)分泌细胞、促肾上腺皮质激素(ACTH)分泌细胞和促甲状腺激素(TSH)分泌细胞; 中腺垂体含有生长激素(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; 后腺垂体内含有一种促黑色素激素(MSH)分泌细胞。雌性条斑星鲽脑垂体内只发现一种类型的GtH分泌细胞, 其内含有大小两种分泌颗粒. 同时也研究了垂体中其他细胞的特点。

Abstract: H. E, Mallory, Heidenhain-Azan and Jafri staining methods and electron microscopy technique were used to investigate the histology and ultrastructure of pituitary gland of female Verasper moseri. The results show that the pituitary of Verasper moseri belongs to dorsoventral style, which consists of two parts: neurohypophysis and adenohypophysis. Neurosecretory fibres were found in Neurohypophysis, and two kinds of pituicytes were recognized in the neurohypophysial tissue in addition to two kinds of neuroepithelial cells. The adenohypophysis was divided into rostral pars distal, proximal pars distal and pars intermedia. Six types of hormone secretory cells were found in adenohypophysis. Prolactin hormone (PROL) cell, adrenocorticotopic hormone (ACTH) cell and thyrotropic hormone (TSH) cell were identified in rostral pars distal. The proximal pars distal expressed three types of hormone secretory cells: growth hormone (GH) cell, gonadotropin hormone (GtH) cell and thyrotropic (TSH) cell. The pars intermedia consisted of melanotropic stimulating hormone (MSH) cell. One type of gonadotropin hormone (GtH) cell was found in the pituitary of matured female Verasper moseri, wherein two types of secreted granules existed. In addition, the characteristics of other cells in the pituitary were discussed. The present study has provided new data for the study of endocrinology in flatfish, and is important reference for the breed of Verasper moseri.
