The purpose of this study was to identify cell types of the pituitary gland of Common Pandora using histochemical methods. Infundibulum region of the organ was cleared through the anterior and posterior lobes. Regional and cellular differences were detected in the anterior lobe using different staining properties. Very dense acidophilic cells were especially located in the rostral pars distalis and it constituted a dark-painted region. There were many basophilic cells in the proximal pars distalis. Pars intermedia boundaries were not very clear, but distinguished by the presence of colloid. Stained in different ways, small acidophils and large basophils reflected differences in hormone contents in granules. Electron microscopic examination of pituitary revealed that cells showed similarities to the features of endocrine secreting proteins and to the fine structure of gonadotrophin in adenohypophysis. Necessary for the hormone synthesis, a well-developed Golgi complex and membrane-located near, there were more intense mid-secretory vesicles a large number of round or oval. There were oval euchromatic nucleus.Pages: 97-102 | 1080 Views 64 DownloadsDownload Full Article:
