Experiments examining the effects of central injections of E-series prostaglandins (PGE) on body temperature have only been done in the light part of a light-dark cycle. The present experiments examined the characteristics of fevers in rats after intraventricular PGE2 injections in both light and dark in a 12:12 h photoperiod. In the light, the change

Regulation of Body Temperature in Man [PDF]
, 1983 Enzymes operate at optimal temperatures, and that is presumably the reason why the body temperature of homeotherms is kept within such narrow limits: a rise of 6°C seems always to lead to death [71]. If man is to remain in thermal equilibrium, the heat gained by his body must balance its losses (Table 8.1).

Body temperature regulation in the rat
Journal of Thermal Biology, 2000In loosely-restrained adult conscious rats exposed to stepwise changes in ambient temperature (T(a)) from 25 to 5 degrees C or from 20 to 35 degrees C, we have recorded body and tail temperatures, metabolic rate (VO(2)), shivering and ventilation (V).

Regulation of Body Temperature
1976Birds, like mammals, are “homeotherms,” which means that they maintain a relatively constant deep-body temperature. Birds are also “endotherms,” a term indicating that they are able to increase their body temperature by generating a considerable amount of heat within their tissues instead of relying on heat gained directly from their surroundings ...

Body temperature and its regulation
Anaesthesia & Intensive Care Medicine, 2008Abstract Body temperature is regulated to a ‘set point’ that is determined by the hypothalamus. The precise value of this set point has a circadian rhythm and is also affected (increased) by trauma and sepsis. In thermoregulatory terms, the body is thought of as a ‘central’ compartment containing all the heat-producing viscera, contained in a cooler ‘

The Regulation of Body Temperature During Fever
Archives of Environmental Health: An International Journal, 1965Abstract : Fever in man was studied calorimetrically to determine, first, the heat flows which cause changes in body temperature and, second, the physiological regulations which directly control these flows. Seventeen reactions induced by typhoid vaccine were observed in environments ranging in ambient temperature from 27 to 43 C.

Regulation of Body Temperature
1992Homeothermy is defined by the Thermal Physiology Commission of the International Union of Physiological Sciences [35] as a pattern of temperature regulation in which cyclic variation in core temperature is maintained within arbitrary limits of ±2°C despite much larger variations in ambient temperature.

Regulation of body temperature by the bluefin tuna
Comparative Biochemistry and Physiology, 1969Abstract Bluefin tuna (Thunnus thynnus Linnaeus) can control the temperature of their bodies (25–30°C) so that the warmest portion of the muscle mass varies only 5°C over a 10°C–30°C range of water temperature.

Body temperature regulation and anesthesia
2018General anesthesia is the induction and maintenance of a state of unconsciousness with the absence of pain sensation. General anesthesia is accomplished by the administration of a combination of inhaled anesthetic gases and intravenous drugs. These medications eliminate behavioral thermoregulatory compensations, leaving only autonomic defenses to ...
