Purification of anterior pituitary and hypothalamic hormones.

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...

Pituitary Hormones: Posterior Pituitary & Anterior Pituitary

The pituitary gland, also known as hypophysis, is a small pea-sized gland about 1 cm in diameter and 0.5 to 1 gram in weight. The pituitary gland resides in a small bony cavity situated at the base of the brain, known as sella turcica, and a pituitary stalk (infundibulum) maintains a connection between the pituitary gland and hypothalamus. The secretion of hormones by the pituitary gland is und...

The hormones of the anterior pituitary.

Secretion 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...
