There's new hope for diabetes patients who hate needles as early testing of oral insulin shows promise.
Scientists in Taiwan have tested a solution of oral insulin in rats but not yet humans. Oral insulin has not worked in the past because it's diluted by the stomach and doesn't reach the bloodstream in pure form.
In these new tests, researchers bundled insulin with a chemical made from the shells of shrimp, crabs and lobsters into small particles. Researchers say the solution was able to lower glucose levels in diabetic male rats.
