		Hormones are chemicals which circulate in the blood stream and spread around the body to carry messages or signals to different parts of the body.
		Hormones are made in endocrine glands and passed from the cells of the gland directly into the blood flowing through the gland.
		The hormones secreted by the posterior pituitary are produced in the hypothalamus and then passed down a tube between the hypothalamus and the pituitary (the pituitary stalk) when they are then secreted into the blood.

		Through their various hormones, the pituitary and hypothalamus control many of the body's automatic functions, as well as play an essential role in growth, development and reproduction.
		The brain cells in the hypothalamus produce hormones (such as growth hormone, prolactin, adrenocorticotrophic hormone, thyrotrophin stimulating hormone, follicle stimulating hormone and leutinizing hormone, vasopressin, and oxytocin), that are then transported down into the posterior pituitary, where they are stored and later released into the bloodstream.
		These hormones are produced by different pituitary cells, which are located in specific regions of the pituitary gland.

		It can be caused by a variety of genetic mutations (such as Pit-1 gene, Prop-1 gene, growth hormone receptor gene, growth hormone gene), absence of the pituitary gland, or severe brain injury, but in most cases no underlying cause of the deficiency is found.
		Measurement of growth hormone and associated binding protein levels (IGF-I and IGFBP-3) confirms that the disorder is caused by dysfunction of the pituitary gland.
		Other hormone levels should be determined, as lack of growth hormone may not be an isolated problem.

	Hormone Replacement
		Hormones are made by glands and are secreted into the bloodstream to stimulate other parts of the body to perform specific activities.
		In studies of adults with growth hormone deficiency, the most common side effects were mild to moderate symptoms of fluid retention, swelling of extremities, painful joints, pain, and stiffness of the extremities, muscle pain, an abnormal sensation (such as burning or prickling), or an abnormal decreased sensitivity to stimulation.
		Although the problem may be reduced by optimal substitution of all pituitary hormones, the potential differences of this group of patients should be kept in mind when assessing the effect of GH on body fluid balances (Homeostasis).

		This hormone is secreted from the back part of your pituitary (or 'posterior pituitary'), and is sent from your pituitary to your kidneys to limit the volume of urine produced.
		If your child is receiving growth hormone treatment it does not necessarily follow that he or she will also need treatment to stimulate the onset of puberty, but around half of such children will need this extra treatment.
		Growth hormone is expensive and this often leads to discussions between your specialist, GP and Health Authority about who should prescribe the treatment (or whether it should be provided at all) - if this problem affects you then please contact the Foundation for advice.

		A pituitary tumor is an abnormal growth in the pituitary gland, the part of the brain that regulates the body's balance of hormones.
		The pituitary gland is a pea-sized endocrine gland located at the base of the brain.
		As the tumor grows, destruction of some of the hormone-secreting cells of the pituitary may take place, causing symptoms related to the underproduction of the hormone that is suppressed (hypopituitarism).

	Adrenocorticotrophic Hormone Antibody Staining Protocol (Site not responding. Last check: 2007-10-19)
		Adrenocorticotrophic hormone (ACTH) is a peptide hormone produced by the anterior pituitary gland that stimulates the adrenal cortex.
		It stimulates the adrenal cortex to secrete glucocorticoid hormones, which help synthesise glucose, catabolise proteins, mobilise free fatty acids and inhibit inflammation in allergic responses.
		The hormone comprises a long chain of amino acids that share a high degree of homology between humans, cows, pigs and sheep.

	adrenocorticotrophic hormone - multiple sclerosis encyclopaedia
		Adrenocorticotrophic hormone (ACTH) is a peptide hormone that is produced by the anterior pituitary gland and the outer cortex of the adrenal glands.
		It's use has been largely superceded by synthetically produced glucocorticoid hormones (e.g., cortisone, prednisone, prednisolone, methylprednisolone, betamethasone, dexamethasone), which can be directly administered without the use of ACTH, are more potent, cause less sodium retention and less potassium loss, and are longer-acting than ACTH.
		It stimulates the adrenal cortex to secrete glucocorticoid hormones, which help cells synthesise glucose, catabolize proteins, mobilise free fatty acids and inhibit inflammation in allergic responses.

	Auk, The: Corticosterone metabolites can be measured noninvasively in excreta of European Stonechats (Saxicola torquata ...
		High-performance liquid chromatography of excreta of a female and a male stonechat injected with tritiated corticosterone showed that corticosterone is excreted in the form of numerous metabolites and that the corticosterone enzyme-immunoassay crossreacted with most of those metabolites.
		Injection of adrenocorticotrophic hormone in one female and seven male stonechats led to a significant increase in the levels of excreted corticosteroid metabolites within 1 h 20 min after administration of adrenocorticotrophic hormone.
		Particularly in small birds, the practicability of hormone studies is often limited by frequency and volume of blood samples that can be obtained.

		The manifestations of a pituitary tumor depend on the hormone secreted by the tumor as well as the pattern of growth of the tumor within the sella turcica.
		Tumors that are often hormonally active are the eosinophilic growth hormone-secreting adenomas (GH), basophilic adrenocorticotrophic hormone-secreting adenomas (ACTH), and the prolactin-secreting adenomas (PRL).
		The major manifestation of the basophilic adenoma is secretion of adrenocorticotrophic hormone, resulting in Cushing's syndrome.

	Thyroid-Stimulating Hormone (Site not responding. Last check: 2007-10-19)
		Thyroid-stimulating hormone, also known as thyrotropin, is secreted from cells in the anterior pituitary called thyrotrophs, finds its receptors on epithelial cells in the thyroid gland, and stimulates that gland to synthesize and release thyroid hormones.
		TSH is a glycoprotein hormone composed of two subunits which are non-covalently bound to one another.
		The alpha subunit of TSH is also present in two other pituitary glycoprotein hormones, follicle-stimulating hormone and luteinizing hormone, and, in primates, in the placental hormone chorionic gonadotropin.

		The hormonal profile of follicular fluid was determined in sows at various stages of ovarian follicle development after injection of adrenocorticotrophic hormone to mimic the elevation in cortisol levels seen with exposure to stressful situations.
		This local hormone is produced within the follicle by granulosa cells and acts with estrogen on oocyte development.
		In general, under normal circumstances hormone concentrations increased in the fluid of the follicles as they developed during the follicular phase of the estrous cycle.

	Acquired immune deficiency syndrome: the glucocorticoid solution.
		The peptide T subregion of gp 120 of human immunodeficiency virus apparently utilizes cellular melanocyte stimulating hormone receptors to competitively inhibit the blocking of interleukin-1 by melanocyte-stimulating hormone.
		Interleukin-1 stimulates CD8+ T-lymphocyte proliferation, as well as causing the release of corticotropin-releasing hormone, thereby stimulating the release of adrenocorticotrophic hormone and cortisol.
		This apparently separate glucocorticoid metabolic route utilized by human immunodeficiency virus is the basis of the cortisol excess seen in human immunodeficiency virus infection.

		It is attached by a stalk to the hypothalamus, an area of the brain that controls the function of the pituitary gland.
		Lack of the hormone leads to loss of function in the gland or organ that it controls (for example, loss of thyroid stimulating hormone leads to loss of function in the thyroid gland).
		Hypopituitarism may be caused by tumors of the pituitary gland or hypothalamus, head trauma, radiation, brain surgery, stroke, or infections of the brain and the tissues that support the brain.

		Pituitary adenomas may secrete hormones, or they may be clinically inactive.
		Other secretory tumors may secrete (1) adrenocorticotrophic hormone (ACTH), causing Cushing disease; (2) growth hormone, causing acromegaly; (3) gonadotropins with clinical presentations reflective of severity and sex; or, rarely, (4) thyroid-stimulating hormone (TSH), causing hyperthyroidism.
		These tumors generally are too small to cause bony erosion or to put pressure on the optic chiasm.
