It is well established that food ingestion induces increased thermogenesis, but the site in man of this increased heat production is still not known. Recent data suggest that brown adipose tissue or the liver may have an important role in this phenomenon. Since recent research provides some evidence to suggest that activation of thermogenesis in a specific organ or tissue may determine increased skin temperature in the surrounding region, we have studied skin temperature in the dorsal interscapular and in the liver regions using infra-red thermography in groups of normal and obese subjects before and after administration of oral glucose. In a separate group of normal subjects we studied oxygen consumption before and after glucose administration. While oral glucose produced a clear increase in thermogenesis, no ascertainable variation was observed in body temperature and, therefore, of heat dispersion in any of the regions studied in either normal or obese subjects.
众所周知，食物摄入会引起产热增加，但人体中产热增加的部位仍不清楚。最近的数据表明，棕色脂肪组织或肝脏可能在这一现象中起重要作用。由于最近的研究提供了一些证据表明特定器官或组织中产热的激活可能决定周围区域皮肤温度的升高，我们使用红外热成像技术研究了正常和肥胖受试者在口服葡萄糖前后肩胛间背部和肝脏区域的皮肤温度。在另一组正常受试者中，我们研究了葡萄糖给药前后的耗氧量。虽然口服葡萄糖使产热明显增加，但在正常或肥胖受试者的任何研究区域中，体温以及因此的热扩散均未观察到可确定的变化。
