Purification of anterior pituitary and hypothalamic hormones.
Pure preparations of pituitary and hypothalamic hormones are needed mainly for (1) their chemical characterisation, which increases our understanding of their biochemistry and makes their synthesis possible; (2) replacement therapy, in which contamination with other pituitary hormones is undesirable; and (3) the development of specific diagnostic assays. Pituitary hormones were first isolated f...
متن کاملSecretion of hypothalamic and pituitary hormones by non-endocrine tumours.
That non-endocrine cancers can produce clinical syndromes of apparent hormone excess has been known for some time (Rees and Ratcliffe, 1974). Now there is ample clinical and biocheinical evidence that many polypeptide hormones may be produced and released by human tumours which originate in tissues which are not normally regarded as sites for the physiological production of the hormones. In som...
متن کاملHypothalamic hormones a.k.a. hypothalamic releasing factors.
Originally searched for and eventually isolated as factors of hypothalamic origin controlling anterior pituitary secretions, these hypophysiotropic peptides are now a chapter of physiology and medical endocrinology of their own. Defying the concept of 'neuropeptides' they and their receptors are now known to be ubiquitous and to have subtle as well as profound effects on a large number of funct...
متن کاملAdaptation of the hypothalamic-pituitary hormones during intensive endurance training.
OBJECTIVE Physical activity leads to changes in the hypothalamic-pituitary hormonal system. However, acute and long-term adaptations have not yet been precisely characterized. In this study, the changes of the hormonal system as a result of marathon training and running a marathon were examined. In particular, we focused on adaptations of the hypothalamic-pituitary-adrenocortical (HPA) axis, re...
متن کاملThe effect of immobilization stress on the HPG axis (hypothalamic - pituitary - gonad) hormones and the number of spermatogonia
Background & Objective: Stress has different effects on the living organisms. In this study the effect of immobilization stress the HPG (hypothalamic - pituitary - gonad axis) hormones secretion and the number of spermatogonia was studied in adult male rats Materials & Methods: 30 male rats were divided into 3 groups. The Control group: who were not exposed to any kind of stress, and two exper...
