[Methods of hypothalamo-hypophyseal portal blood collection].
Abstract
It is possible to assay hypothalamic factors in hypophysial portal blood from several species. However, hypophysial portal blood collection must be performed after anesthesia and surgical stress which can both modify the regulation of hypothalamo-pituitary secretion. However, this method has allowed some progress in our knowledge of the hypothalamic control of pituitary secretion. The methodology, advantages and limits of hypophysial portal blood collection are briefly described in this review.
