The scientists went to a hospital ward with diabetic children, comatose and dying from diabetic keto-acidosis. This is known as one of medicine's most incredible moments. The scientists went from bed-to-bed and injected the children with the purified extract - insulin. As they injected the last comatose child, the first child injected began to awaken. One by one, all the children awoke from their diabetic comas. A room of death became a place of joy and hope.
