Document Summary
Why was there a sudden, then steady, increase in diabetic survival rates beginning in the. The biggest breakthrough came in 1921 when frederick banting and charles best conducted a series of experiments one summer in the laboratory of j. j. r. Like minkowski and von mering, they showed that removing the pancreas from dogs made them diabetic. Then they went a step further and painstakingly took fluid from healthy dogs" Islets of langerhans, injected it into the diabetic dogs and restored them to normalcy - for as long as they had the extract. With the help of a biochemist colleague named j. B. collip, they were then able to extract a reasonably pure formula of insulin from the pancreas of cattle from slaughterhouses. In january, 1922, a diabetic teenager in a toronto hospital named leonard. Thompson became the first person to receive an injection of insulin. He improved dramatically, and the news about insulin spread around the world like wildfire.
