Diabetes - a cure
The ancient Greeks referred to diabetes as a ‘wasting disease’ due to the amount of urine that was passed, the amount of fluid that was required and the subsequent weight loss which resulted in death. It wasn’t until 1921 that doctors, Banting and Best first described the origins of diabetes in the pancreas. They removed the pancreas from dogs and found the dogs became diabetic and died. They found that by taking extracts of the pancreas, mixing it up in the laboratory and giving it back to the dogs, they could cure the diabetes. When insulin was injected into human diabetics the results were dramatic. The clip also looks at the production of insulin using genetically engineered yeast producing insulin that is chemically identical to human insulin.
