Title: THE NOBEL PRIZE IN PHYSIOLOGY OR MEDICINE 1947


1
THE NOBEL PRIZE IN PHYSIOLOGY OR MEDICINE 1947
2
The Nobel Prize in Physics 1947
  • "for his investigations of the physics of the
    upper atmosphere especially for the discovery of
    the so-called Appleton layer"

Sir Edward Victor Appleton (United Kingdom)
3
The Nobel Prize in Chemistry 1947
  • "for his investigations on plant products of
    biological importance, especially the alkaloids"

Sir Robert Robinson (United Kingdom)
4
The Nobel Prize in Literature 1947
  • "for his comprehensive and artistically
    significant writings, in which human problems and
    conditions have been presented with a fearless
    love of truth and keen psychological insight"

André Paul Guillaume Gide (France)

THE NOBEL PRIZE IN PHYSIOLOGY OR MEDICINE 1947
GERTY THERESA CORI, NÉE RADNITZ USA
(1896-1957) 3rd woman to win the Noble prize.
CARL FERDINAND CORI USA (1896-1984)
  • "for their discovery of the course of the
    catalytic conversion of glycogen"

7
CORI CYCLE
The Cori cycle is their explanation for the
movement of energy in the bodyfrom muscle, to
the liver, and back to muscle.

Bernardo Alberto Houssay(Argentina)
(April 10, 1887 September 21,1971)
  • "for his discovery of the part played by the
    hormone of the anterior pituitary lobe in the
    metabolism of sugar"

9
  • Carbohydrates produced from food or liver
  • Used by muscles
  • Production and consumption of carbohydrates-Consta
    nt blood sugar level
  • The liver
  • Hypoglycemia when liver is removed
  • Hyperglycemia-the liver diminishes or ceases the
    production of sugar, and stores it.

10
  • The pancreas secretes insulin in adequate
    quantities so as to maintain a normal blood sugar
    level, and the blood sugar level regulates the
    amount of insulin secreted. Thus hyperglycemia
    increases the secretion of insulin and
    hypoglycemia diminishes or completely inhibits it.

11
  • He found that hypophysectomized dogs were
    hypersensitive to the toxic and hypoglycemic
    action of insulin
  • These discoveries stimulated the study of
    harmonal feedback control mechanisms which are
    central to all aspects of modern endocrinology.

12
Outline
  • Carbohydrate metabolism and other metabolic
    processes are regulated by the balance maintained
    between the secretion of several endocrine
    glands.
  • Diabetes and other metabolic diseases are a
    disturbance in this endocrine equilibrium.

  • Due to the body's ability to hold no more than
    around 2,000 kcal of glycogen, marathon runners
    commonly experience a phenomenon referred to as
    "hitting the wall" around the 20 mile (32 km)
    point of a marathon. (Approximately 100 kcal are
    utilized per mile, depending on the size of the
    runner and the race course.) When experiencing
    glycogen debt, runners many times experience
    fatigue.
