  3. College life • Charles Best went to the University of Toronto • He then went into the army and became a sergeant in WWI. • When he went back to the University of Toronto Best his major was biology and science.

  4. First Meetings • Finally Frederick Banting and Charles Best met through John Macleod. They decided to try to work on finding a way to treat diabetes

  5. Experiments • Banting was convinced that the pancreas was where the cure would be. He tested a procedure on a dog.

  6. Experiments cont. • Banting was convinced that if you could isolate the pancreas it could produce insulin which would keep the sugar level down.

  7. Experiments cont.. • They were ready to extract on July 30. Banting would do the surgery and Best would do the test on the sugar level in the blood and urine

  8. Experiments cont.. • They tested the insulin by taking out the pancreas and they created the extract by chopping up the pancreas and grinded it.

  9. Experiments cont. • The experiment worked!the blood sugar went down from .20 to .12 in an hour,and then down to .11.

  10. Experiments cont. • The dog died days later because of an impurity in the extract, but Macleod hired James Bertram Collip, a biochemist to help purify it.

  11. Experiments cont. • They wrote their first paper called “The Internal Section of the Pancreas” which was published. It appeared in the February 1922 issue of the “Journal of Laboratory and Clinical Medicine”

  12. First Human Experiment • Their first patient was Leonard Thompson, who was 14 years old in 1922 • He had diabetes for two years and was so weak his weight was down to 65 pounds. He was expected to only live a couple more weeks.

  13. First human patient cont. • Best and Banting tested the insulin on themselves first to make sure there were no side effects. • After impurity problems with the insulin, Thompson became better and lived until dying in a motorcycle accident.

  14. Nobel Prize • Banting and Macleod got the Nobel Prize in 1923 in physiology and medicine. • Banting thought that Best deserved the prize as well so he split the money with Best equally. Macleod split his money with Collip

  15. Achievements in College • Best got his M.A. in 1922 • He got his M.D. in 1925 • He was awarded the Ellen Mickle Fellowship for highest standing in the medical course

  16. Later achievements • After he got married to Margaret Mahon in 1924, they and their two sons went to England.

  25. Awards and Achievements cont. • Some of the books were: ‘The internal secretion of the pancreas’ (1922), ‘The physiological Basis of medical practice’(1937), ‘The living body’(1952), and ‘The human body, its anatomy and physiology’(1956)

  26. Achievements and Awards • Best became the chairman of Banting and Best Department when Banting died • He was elected a fellow of the royal society of London, and the Royal society of Canada
