Abstract

Exposure of rats to a temperature of 1 degree C resulted in a temporary decline in respiratory quotient to a minimum on the 4th day of exposure, with subsequent recovery. 2. Metabolism stabilized after 4-6 days of cold exposure. 3. Body composition was determined for control rats and rats exposed to 2 or 23 degrees C for 2 weeks. 4. Animals kept at 2 degrees C had a lower fat content than other groups, with a higher iodine value. 5. Mineral content indicated that bone growth continued during cold exposure.

摘要

将大鼠暴露于1摄氏度的温度下，会导致呼吸商在暴露的第4天暂时下降至最低水平，随后恢复。2. 冷暴露4-6天后，新陈代谢稳定下来。3. 测定了对照大鼠以及暴露于2摄氏度或23摄氏度环境2周的大鼠的身体组成。4. 饲养在2摄氏度环境下的动物脂肪含量低于其他组，碘值更高。5. 矿物质含量表明，冷暴露期间骨骼仍在生长。
