| Outline of Final Research Achievements |
The present research aimed, (1) to develop a mouse model for evaluating the thermal tolerance of postmenopausal women, ② to test if decrease of estradiol secretion augments a risk of heat stroke (autonomic reaction, behavioral reaction, temperature sensation, cognitive function and behavior related to the heat), and it affects time dependence or not. We completed a system to evaluate the heat escape behaviors of mice and at the same time evaluated metabolic rate under heat. Estradiol contributed to the decrease in metabolic rate at the time of heat loading, and it seemed that this decrease is related to the decrease of the heat resistance. Also, its effect was noticeable in the light period. It was thought that the heat escape behavior was not affected.
