Ulcer: A break in the skin; a deep sore. People with diabetes may develop ulcers from minor scrapes on the feet or legs, from cuts that heal slowly, or from the rubbing of shoes that don't fit well. Ulcers can become infected and should be treated promptly.
Ultralente insulin: A type of insulin that is long acting, usually the action of this type of insulin works for 25-36 hours after injection. This type of insulin has an onset of action four to five hours after injecting and works most powerfully at eight to 14 hours after injection.
Unit of insulin: The basic measure of insulin. U-100 is the most common concentration of insulin. U-100 means that there are 100 units of insulin per milliliter (ml) of liquid. For the occasional patient that has severe insulin resistance insulin is available as a U-500 form.
Unstable diabetes: See brittle diabetes.

A DIABETIC woman from Northampton has been presented with a medal to mark 70 years of coping with the condition.
When Grace Jarnell was diagnosed with Type 1 diabetes while aged 12 in 1942, treatment was so basic she had to heat her own samples at home over a Bunsen burner to see if she needed insulin.
Now, more than 100,000 injections later, she has defied the worst fears of doctors and been awarded a medal in recognition of seven decades of coping with the condition.
Scientists at the Diabetes Research Institute have developed a revolutionary technique to provide critical oxygen for maintaining the survival of insulin-producing cells.
