Over twenty years of work on the Hanson Ranch (HR) Bonebed in the Lance Formation of eastern Wyoming has yielded over 13,000 individual elements primarily of the hadrosaurid dinosaur Edmontosaurus annectens. The fossil bones are found normally-graded

Growth hormone and prolactin secretion in water-deprived chickens

Autor: T.R. Hall, Arthur Chadwick, S. Harvey

Publikováno v: General and Comparative Endocrinology. 54:46-50

The deprivation of water for 12 or 24 hr increased the prolactin concentration in the plasma of immature chickens but had no effect on the circulating growth hormone (GH) level. The increase in plasma prolactin level reflected an increase in the basa

Effect of estrogen on calcium homeostasis and pituitary hormones in the growing chick

Autor: A. D. Care, Barbara A. Sommerville, Arthur Chadwick, R. Swaminathan, Colin G. Scanes, Steve Harvey

Publikováno v: General and Comparative Endocrinology. 76:261-266

An experiment was carried out to investigate the effect of a range of estradiol (E2) doses (0.1-6.5 micrograms/g body wt/day) on vitamin D metabolism and the plasma levels of growth hormone (GH) and prolactin (PRL) in the growing chick. Doses of 0.5-
