Other
Other related information We will analyze T lymphocyte function including co-inhibitors in 30 tyep 2 diabetes patients who were hospitalized for a purpose of treating hyperglycemia. As a normal control, the same analysis will be performed in 30 patients hospitalizd for the treatment of diseases other than diabetes. For the diabetes patients, the same items will be measured not only at admission but also at discharge with the improvement of hyperglycemia.
