age related cytochemical changes of thymic endocrine cells were studied in 78 day old chicks at five day interval to age of day 60 employing a panel of cytochemical stains. methenamine silver revealed cell morphology including cell processes distinctly while diamine silver revealed a stronger argentaffinity in these cells. the cells had greater affinity for diamine silver compared to methenamin...

the disposition and cellular organization of the endocrine pancreas were studied in three species of freshwater teleosts viz., labeo bata (hamilton, 1822), sperata aor (hamilton, 1822) and chitala chitala (hamilton, 1822) using histological techniques. in l. bata, the endocrine pancreas tissues were mainly distributed in the adipose tissue among the intestinal coils and adjacent to extrahepatic...

The aim of this study was to detect the regional and mucosal distribution of endocrine cells that secrete gulcagon, somatostatin, Chyholecystokinin-8 (CCK-8), serotonin, secretin, substance P (SP) and histamine in the small and large intestine of New Zealand white rabbit (Oryctolagus cuniculus L.) using immunohistochemical peroxidase-antiperoxidase (PAP) method. It was found that most of the im...

The respiratory tract contains numerous peptides secreted from special pulmonary epithelial cells whichare called endocrine cells. The function of neuroendocrine cells is modulated by amines. Serotonin has strong vasomotor and bronchomotor effects in the airway mucosa. The objective of this study was to determine presence and distribution of serotonin-positive endocrine cells in respiratory tra...

 The endocrine cells of Salmo trutta macrostigma stomach and pyloric caeca have been investigated using immunohistochemical techniques. 8 antisera were tested and 6 of them were detected in the endocrine cells serotonin, somatostatin, substance P, galanin, CCK and neuropeptide Y. These immunoreactive cells are described for the first time in the stomach and pyloric caeaca of Salmo trutta macros...

background although neuregulin-1 （nrg1）and its receptors have been indicated at the mrna level in partial human endocrine organs and its functional roles have been evaluated in vitro, their morphological distribution in higher animals are not fully studied. the present research focused on expression of nrg1 and its main receptors erbb2 and erbb4 in main endocrine organs of the rhesus monkey. ma...
