Microfluorimetric quantitation of catecholamine fluorescence in rat median eminence. II. Turnover changes in hormonal states.
Catecholamine nerve terminals in the rat median eminence have been studied using the fluorescence histochemical technique of Falck and Hillarp in combination with quantitative microfluorimetry. The catecholamine fluorescence intensities recorded from various parts of the median eminence were all found to be within the linear part of the dopamine or noradrenaline concentration-fluorescence relat...
متن کاملOntogeny of the expression of catecholamine synthesising enzymes in the female porcine median eminence arcuate nucleus complex (MEARC).
The ontogeny of the catecholaminergic system of the median eminence (ME) arcuate nucleus (ARC) complex (MEARC) has been studied in various animal species but so far, nothing has been learnt about the development of catecholaminergic structures in the porcine MEARC. To study this problem the hypothalami from animals at different ages (six groups) were collected. Nerve structures immunoreactive (...
متن کاملSemaphorin7A regulates neuroglial plasticity in the adult hypothalamic median eminence
Reproductive competence in mammals depends on the projection of gonadotropin-releasing hormone (GnRH) neurons to the hypothalamic median eminence (ME) and the timely release of GnRH into the hypothalamic-pituitary-gonadal axis. In adult rodents, GnRH neurons and the specialized glial cells named tanycytes periodically undergo cytoskeletal plasticity. However, the mechanisms that regulate this p...
متن کاملLocal difference in concentration of vasopressin and monoamines in the equine median eminence.
The hypophysial stalk of the horse had a typical structure of the median eminence and contained noradrenaline, dopamine, serotonin, vasopressin and paraldehyde fuchsine-stainable material. The posterior wall of the hypophysial stalk contained higher concentration of noradrenaline than the anterior and lateral walls. On the other hand, the anterior and lateral walls contained dopamine but the po...
متن کاملVacuolar Pathology in the Median Eminence of the Hypothalamus Following Hyponatremia
The median eminence of the hypothalamus is an important conduit by which neurosecretory hormones from hypothalamic nuclei are delivered to the pars nervosa (neural lobe) of the pituitary en route to the bloodstream. Dilutional hyponatremia was produced in adult rats to determine the effect on the morphology of the median eminence of the hypothalamus. Hyponatremia was caused by reducing electrol...
