Insulin Discovery |
|||||
 |
Fredrick Banting and John Macleod were awarded the Nobel Prize for their discovery of Insulin. It was the first time that a Nobel Prize was awarded so soon after a discovery in 1923. Banting, a young orthopaedic surgeon began working as a demonstrator in physiology in 1920 at the University of Eastern Ontario in Canada. Here in the laboratory of Mecleod and with the help of a medical student named C.H. Best, he conducted research into diabetes. They discovered that in diabetes the pancreas is unable to secrete enough of a hormone called Insulin which regulated the blood sugar level. They extracted the hormone in 1921 from the cells in the pancreas called the Islets of Langerhans. A young biochemist, J.B. Collip helped Banting and Best secure a regular supply of pig's pancreas glands from a local abattoir. After a series of trails on dogs, injection of insulin was given to human patients with astounding success. In a wonderful show of large heartedness, both Banting and Macleod insisted on sharing the Prize with their colleagues Best and Collip.
