With the method of histological section and electronic microscope, the ultra-structure in different periods of pituitary of female long-snout catfish(Leiocassis longirostris) were studied at different development stages and physiological conditions. The results were as follows.The pituitary of long-snout catfish has adenohypophysis and neurohypophysis. The adenohypophysis have six cell types, i.e,gonadotrophs(GTH), thyrotrophs(TSH), somatotrophs(STH), melanotroph (MSH),lactotrophs(PRL) and adrenocorticotrophs(ACTH)...

With the method of histological section and electronic microscope, the ultra-structure in different periods of pituitary of female long-snout catfish(Leiocassis longirostris) were studied at different development stages and physiological conditions. The results were as follows.The pituitary of long-snout catfish has adenohypophysis and neurohypophysis. The adenohypophysis have six cell types, i.e,gonadotrophs(GTH), thyrotrophs(TSH), somatotrophs(STH), melanotroph (MSH),lactotrophs(PRL) and adrenocorticotrophs(ACTH) cells. In neurohypophysis, there are three types of neurosecretory fibres, types A_(1), A_(2) and B. There are different types' granules in type A neurosecretory fibres axone. In type B neurosecretory fibres axone, there are many small transparent vesicles.Before spawning, GTH cytoplast are full of high density electron secretory granules,big and small. TSH cells cytoplast evacuate secretory granules; electron density decreases and large vacuoles appeare. STH cells are in activitive synthesis and secretion. MSH cells have few secretory granules, of which the quite developed oplasmic reticulums distribute around nucleus. The electric density of PRL cells with secretory granules is high. There are a few secretory granules in ACTH cells. After spawning, GTH cells evacuate secretory granules. Vacuoles appeare in TSH cells. Rough endoplasmic reticulum in STH cells are circumnuclear. Secretory granules are more but small, in MSH cells, rough endoplasmic reticulum is flat or reticulate. Few secretory granules in PRL cells distribute inequably. In ACTH cells endoplasmic reticulum distribute near nucleus. In autumn, there are GTH_(1)cells and GTH_(2) cells in GTH cells. More secretory granules distribute around nucleus in GTH_(1)cells, and less in GTH_(2) cells. Rough endoplasmic reticulum around nucleus in STH cells is very developed. Its mitochondrias increase. Endoplasmic reticulum in TSH cells expands to froth. There are apparent diploid nucleus in MSH cells. There is a nucleolus in one of nucleus. Secretory granules in cytoplast increase mere than in the period of post-spawn. Circle secretory granules in PRL cells distribute inequably. Mitochondria and endoplasmic reticulum in ACTH cells distribute around nucleus, less secretory granules in cytoplast distributing inequably. In winter, there is a small number of secretory granules scattering around nucleolus in GTH cells. There are more minitype secretory granules in TSH cells, andmany long rough endoplasmic reticulum in nucleus periphery. The numbers of secretory granules in STH cells is relatively small. The activity of synthesis and secretion decreases. The spumescent rough endoplasmic reticulum in MSH cells ranks around nucleus. The ultra-structure of ACTH and PRL cells hare no obvious changes from autumn.During all stages, the neurosecretory fibres in eurohypophysis shows some varieties. There are global and no envelopes secretory granules before propagation. It evacuates secretory granules after propagation. Secretory granules can be seen in some of it in autumn, but the number is relatively small. In winter, it has no apparent changes.
