Abstract
In homotherms, body temperature is one of the most vital, constant, regulated parameters. As it has been shown in many investigations, the ability to maintain body temperature, to cope with variations in ambient temperature and to develop fever is compromised with aging (1,2). Most of the data indicate a deficiency in aging to cope with a cold environment (3,4,5,6). Another change occurring with aging is a reduced amplitude of body temperature oscillation in animals and humans (7,8,9,10). It is the purpose of the present investigation to elucidate the relationship between body temperature and aging in rats at different ambient temperature and different light schedules. Moreover, we tried to correlate hypothalamic, prostaglandin E2 (PGE2) production with aging and body temperature.
