Dogs helped us discover a cure to diabetes

Insulin was discovered in dogs as being a way to regulate the sugars from inside our blood. In 1916 Nicolae Paulescu, a Romanian scientist, developed an aqueous pancreatic extract which, when injected into a diabetic dog, had a normalizing effect on blood-sugar levels. From that point on we were ready to use insulin in the form of injections and let people suffering from diabetes live a normal life again.
