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 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...

In vitro culture systems using bone marrow cells from BALB/C mice were set up in medium supplemented with spleen-derived medium. Bone marrow cells grown in spleen-derived medium gave rise to cultures containing >97% mast cells. The cells were used in polarisation chemotaxis assays with the intention of determining the effect of nerve tissue-derived neurotransmitters on mast cell migration. ...

serotonin receptors are involved in pathophysiology of schizophrenia and may mediate other neurotransmitter effects. we investigated serotonin receptors gene expression in peripheral blood mononuclear cells (pbmc) of naïve schizophrenic patients, before and after treatment. also serotonin receptor gene expression was compared in two treatment groups including haloperidol and olanzapine. the pbm...

 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...
