| Outline of Final Research Achievements |
The purpose of this study was to examine the validity of supraclavicular subcutaneous tissue temperature as an index of brown adipose tissue activity. We measured the brown adipose tissue activity in winter by FDG-PET/CT method. We also performed cold exposure test and measured metabolic rate, rectal and skin temperatures, blood flow, and subcutaneous tissue temperatures at supraclavicular and breast during cold exposure for 90 min in summer and winter. As a result, the SUVmax, which was an index of brown adipose activity, was not related with supraclavicular skin temperature but related with the supraclavicular subcutaneous tissue temperature. Also the supraclavicular subcutaneous tissue temperature maintained during cold exposure in winter, but that was decreasing in summer. These results suggested that the brown adipose tissue activity was evaluated by the supraclavicular subcutaneous tissue temperature.
