Argentine #physiologist and corecipient, with Carl and Gerty Cori, of the 1947 #NobelPrize for Physiology or #Medicine.

He was noted for discovering how #pituitary #hormones regulate the amount of #bloodsugar (#glucose) in #animals.

The #hypophysis, or the pituitary gland, is an important, but small secreting #gland at the base of the #brain, where it lies sunk in a bony hollow in the most sheltered spot of the whole body. Its size is that of a bean in man, a pea in the dog, and a radish seed in the large toad Bufo marinus, which is plentiful in the Argentine.

Houssay worked with #dogs from which the hypophysis, or sometimes only its anterior lobe, was surgically removed. He then found that a daily implantation of anterior lobe of hypophysis from #toads on the operated animals protected the latter from unbalanced levels of #insulin, otherwise present.
