Sir Frederick Grant Banting (1891-1941)
|
|
Life Description
|
|
Sir Frederick Grant Banting was a Canadian physician, physiologist,
|
|
and Nobel winner in 1923 for the discovery of the hormone insulin, used in
|
|
treating diabetes.
|
|
|
|
Early Life
|
|
Banting was born November 14, 1891, on a farm near Alliston, Ontario.
|
|
The death of his friend made him having the desire to be a doctor.
|
|
However, his father was a devoutly religious man, and hoped that Frederick
|
|
would become minister. After he graduated from high school, the conflicts
|
|
with his parents begun. His parents finally persuaded him to enrol in the
|
|
liberal art course at Victoria College, Ontario. In 1910, he and his
|
|
cousin Fred Hipwell began their studies at Victoria College.
|
|
|
|
However, Banting's mind was still on medicine. After several
|
|
arguments with his parents, he entered the University of Toronto Medical
|
|
School in the fall of 1912. His cousin quoted, "He was a steady,
|
|
industrious student. He had no top marks or even honor standing, but there
|
|
never was any doubt that he would pass."
|
|
|
|
World War I
|
|
While he was still in school, World War I started. In the spring of
|
|
1915, his name was enlisted in the Canadian Army. However, his commanding
|
|
officer, arranged him for his education. Hours after the successful
|
|
completion of his final exams in December 1916, he was back in uniform.
|
|
Within a few months, he was serving in the Canadian Army Hospital at
|
|
Ramsgate, England. He then voluntarily transferred to the front line near
|
|
Cambrai, France because he felt he was not doing enough. He used his
|
|
intelligence to capture three fully armed Germans without any use of
|
|
weapons! This earned a rank of the Captain.
|
|
|
|
He kept working at the frontline. On the morning of September 28,
|
|
1918, a shell burst close by and a piece of shrapnel buried itself in
|
|
Banting's right arm. It was so bad that a doctor informed him that they
|
|
had to amputate his arm. However, he refused, He did an operation to
|
|
himself. Even though it was a long, slow process, his arm finally did
|
|
heal.
|
|
|
|
After World War I
|
|
By the time he was recovered, he went back to Toronto. He opened an
|
|
office as a surgeon. However, after 4 months, he only earned 14 dollars!
|
|
Therefore, he transferred to University of Western Ontario as a teacher.
|
|
|
|
Winning the Nobel Prize
|
|
In the year 1921, he performed a major breakthrough of modern
|
|
science--he had brought a dying victim of diabetes back to life. This
|
|
discovery led him to win the 1923 Nobel Prize.
|
|
|
|
Even though he could turn wealthy by patenting insulin, he chose to go
|
|
back to University of Toronto, and made sure that public could have insulin
|
|
injection cheap and easily.
|
|
|
|
The world continued to honor and reward him. In 1934, he was made a
|
|
Knight Commander of the Order of the British Empire by King George V.
|
|
|
|
The Death of Sir Banting
|
|
Later in his life, he joined the army in World War II. Aviation
|
|
medicine became his favourite line of research. Shortly before his
|
|
departure on a mission to Great Britain, he was uneasy and told his cousin
|
|
Fred Hipwell that he was "a little bit afraid." On February 21, 1941, the
|
|
plane carrying Banting 50 miles out from Newfoundland airport, heading over
|
|
the Atlantic Ocean. One of the engines sputtered and failed. It crashed
|
|
while landing on the ground.
|
|
|
|
Thousands mourned Banting's passing. He was buried as a soldier in a
|
|
simple ceremony. The last words said over the flag- draped coffin were:
|
|
"It is not given to everyone to die for his country, for freedom and
|
|
justice, to die in the path of duty....Such was the earthly end of
|
|
Frederick Grant Banting. Tragic? Yes, but also triumphant."
|
|
|
|
Discovery and Contribution
|
|
The main discovery of Sir Banting of course was the insulin that could
|
|
cure Diabetes Mellitus.
|
|
|
|
|
|
What are Insulin and Diabetes Mellitus
|
|
Insulin is a hormone that produces by the islets of Langerhans, which
|
|
are the groups of cells in pancreas. Diabetes Mellitus would cause the
|
|
entry of glucose impaired, a result either of a deficiency in the amount of
|
|
insulin produced or of a blocking of its action. The sugar builds up in
|
|
the blood and is excreted in the urine. This would cause the body became
|
|
extremely thirsty, weight is lost and feels very tired. Since the body is
|
|
lack of glucose, it begins to break down the stored fat. The blood would
|
|
become acidic and interfere with respiration. Usual outcome of this would
|
|
be diabetic coma if it is not treated properly. During that time, in U.S.,
|
|
almost 300,000 people died of diabetes every year. Therefore, the
|
|
discovery of insulin was a really incredible contribution to the world.
|
|
|
|
How did he discover it?
|
|
At two o'clock in one morning during 1920, while he was struggling
|
|
with his sleep, he got an idea about a diabetic dog:"Tie off pancreatic
|
|
ducts of dogs. Wait six to eight weeks for degeneration. Remove the
|
|
residue and extract." However, he was only a resident in University, he
|
|
had to ask the professor for permission. At that time, the chief professor
|
|
J.J.R.Macleod didn't his motive. All he gave Banting was eight weeks in a
|
|
laboratory in an attic, ten dogs, and an assistant who knows how to
|
|
measure the level of sugar and blood. The assistant's name was
|
|
Charles M. Best.
|
|
|
|
By May 1921, he started his experiment. He chloroformed the first
|
|
dog. He opened the abdomen and tied off the pancreatic ducts with little
|
|
loops of catgut, which would normally stop the flow of the juices. This
|
|
should result a diabetic pancreas. However, he failed this easiest part
|
|
because the catgut had disintegrated, permitting the digestive juices to
|
|
flow. However, that didn't discourage him. The next time, he use the silk
|
|
thread and tied several dogs in two or three places. Then he waited.
|
|
|
|
By the time the waiting period was over, the eight weeks period was
|
|
ended too. Fortunately, Macleod was away in Scotland. However, he still
|
|
had to sell all of his properties in order to have money to continue.
|
|
|
|
Nine days later, they had completely removed the pancreas from a dog,
|
|
which gave it a severe case of diabetes. It was not dead but it could not
|
|
even hold its head up.
|
|
|
|
He chloroformed this dog and another duct-blocked dog. He removed the
|
|
pancreas from the duct-blocked one and took the islet cells. He grounded
|
|
it with sand, and mixed it with salt water. Then, he injected it into a
|
|
vein of the dying dog. For the next minutes, Best, his assistant, kept
|
|
taking samples of blood from the sick dog. After about an hour, Best
|
|
shouted,"Her sugar is down. It is almost normal!" This was a major
|
|
discovery of modern science. They made a dying diabetic animal survive
|
|
again. They named the islet cells isletin.
|
|
|
|
However, the next day, the dog was dead. This meant the cells only
|
|
brought a temporary drop in sugar level. However, it was not practical to
|
|
kill healthy dogs to save the sicked one. Therefore, they had to think of
|
|
another way to obtain isletin. Banting got an idea from his early days
|
|
experiment from the farm. The farmers always threw away the cows' embryos,
|
|
which was a resource to get the cells. They mixed the mixture of alcohol
|
|
and acid, inserted it into the cows. It worked. The mixture destroyed the
|
|
digestive juices that interfered with the isletin. Now, they got enough
|
|
isletin to continue their experiment.
|
|
|
|
Finally, they had to prove the most important part. Would isletin be
|
|
safe to human? Banting and Best inserted the isletin into each other,
|
|
which resulted no negative reaction. Also, they tested it with a boy laid
|
|
close to death. It made the boy having a daily gain in strength and
|
|
health, as long as he kept on taking it.
|
|
|
|
By that time, Macleod returned. He began to turn all of his energies
|
|
to support Banting. However, the first thing he did seem to be
|
|
meaningless: changes isletin into insulin. Then he assigned several
|
|
experts to support Banting. This helped Banting to perform his experiments
|
|
more convenient and easier.
|
|
|
|
The news of discovery spreaded over the world. Again this earned him
|
|
a Nobel Prize in 1923 and a honourable life until his death in 1941.
|
|
Conclusion
|
|
|
|
We should be proud with the contributions by Sir Frederick Grant
|
|
Banting to this whole world. Without all his hard works, more people may
|
|
have died because of diabetes. He also helped Canada to establish a good
|
|
medication position in the world.
