The coexistence of peptides and catecholamines is a constant feature of the chromaffin cells. The coexistene of multiple peptides is also seen in some chromaffin cells. This indicates that there are several subpopulations among the chromaffin cells in terms of bioactive substances contained. Diverging from the traditional view that intraadrenal nerves are predominantly preganglionic cholinergic ones innervating the chromaffin cells, the nerves are revealed to consist of heterogeneous populations containing various different neuropeptides. These are presumed to be of several different origins. The nerves innervate not only the chromaffin cells but partially the cortical cells, too, and are further associated with intraadrenal blood vessels. Several possible courses of action for the neuropeptides in the adrenal gland have been proposed based on immunohistochemical findings. The adrenal gland should be regarded as an endocrine organ, secreting not only catecholamines but also various neuropeptides; it likely plays more important and varied roles than previously believed for the maintainance of the internal environment of the body.","PeriodicalId":8387,"journal":{"name":"Archivum histologicum Japonicum = Nihon soshikigaku kiroku","volume":"48 5","pages":"453-81"},"PeriodicalIF":0.0,"publicationDate":"1985-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1679/aohc.48.453","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"13569258","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The cells have a wide base and a narrow apex in the lower and middle portions of the pit, while at the opening of the pit to the gastric lumen, they become taller and funnel-like in shape, and are characterized by well developed interdigitations and intermediate filaments sometimes associated with desmosomes. During this transformation of the cell contour, the nucleus moves towards the upper region of the cytoplasm, whereas the Golgi apparatus moves downwards to the infranuclear region. Then, there appear secondary lysosomes showing crinophagy and lipid droplets around or near the Golgi apparatus. Though the basal part of the cells is very small, no images of the detachment of the basal plasma membrane from the basal lamina could be seen even at the site of severe cell degeneration. The tall funnel-shaped cells showing these characteristics are located on the interfoveolar ridges of the underlying fibrous layer and line the free surface of the stomach. Therefore, the interfoveolar cells which have lost the activity of secretory granule production and are going to undergo physiological degeneration are thought to be highly differentiated elements as a covering epithelium to protect the underlying tissue, resembling in this respect the keratinocyte of the epidermis.","PeriodicalId":8387,"journal":{"name":"Archivum histologicum Japonicum = Nihon soshikigaku kiroku","volume":"48 5","pages":"527-39"},"PeriodicalIF":0.0,"publicationDate":"1985-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1679/aohc.48.527","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"14948175","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

With light microscopy the cytoplasm of the glomerulosa cells was faintly immunostained, while that of the fasciculata-reticularis cells was intensely immunostained by both monoclonal antibodies for cytochrome P-450SCC and cytochrome P-450(11)beta, though the capsular connective tissue cells and the adrenal medullary cells were entirely negative for these reactions. Electron microscopic immunohistochemistry revealed that the positive reaction products for cytochromes P-450 were present on the matrix side of the inner mitochondrial membrane including the tubulovesicular cristae of the cortical cells, and especially of the fasciculata and reticularis cells.

Astrocytes exhibited alkaline phosphatase activity on the plasma membrane of the endfeet facing the vascular basement membrane and at the gap junctions, but not on other parts of the plasma membrane or in the cytoplasm. Immature astrocytes containing small bundles of filaments, a few glycogen granules and other cell organelles, exhibited alkaline phosphatase activity on the inner and outer nuclear membranes, the outer mitochondrial membrane and on portions of the plasma membrane. Thus, it was concluded that the distribution of alkaline phosphatase in astrocytes shifts from the cytoplasm and plasma membrane to the endfeet and gap junctions with cell maturation. Alkaline phosphatase activity was detected on the plasma membrane of the subependymal cells and surrounding processes, but not on the ependymal cells.","PeriodicalId":8387,"journal":{"name":"Archivum histologicum Japonicum = Nihon soshikigaku kiroku","volume":"48 5","pages":"511-7"},"PeriodicalIF":0.0,"publicationDate":"1985-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1679/aohc.48.511","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"14951726","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
