ABSTRACT
Twelve normal female adults were studied using a new model of infrared thermography on the thermographic patterns, the average and the maximum skin temperature of the selected areas, the change of the skin temperature in menstrual cycle and the change of the skin temperature after immersion of the right hand in ice water. The new thermoviewer (JTG-500M) has a computer and can calculate the average and maximum temperature in any rectangular area we draw. It made us possible to detect slight change of the skin temperature precisely. The results were as follows:<br>1) The average temperature of the trunk was higher than those of the lower extremities and the dorsal surface of the hand.<br>2) Among the maximum temperatures of the selected areas, the highest was of the trunk, the second was of the dorsal surface of the hand and the last was of the lower extremities.<br>3) Of the change in menstrual cycle, a significant positive correlation between the basal body temperature and the skin temperature was found. The skin temperature in the progestational phase was significantly higher, by 0.5°C to 0.7°C, than that in the estrogenic phase.<br>4) The change of the skin temperature after immertion of the right hand in ice water for one minute was surveied at the chest, the abdomen, the back, the dorsal surface of the left hand and the left lower extremity during five minutes. While the skin temperature at the chest and the back dropped, the dorsal surface of the left hand got higher clearly. No change was found at the abdomen and the lower extremity.
