Thermoregulatory responses to preoptic cooling in unrestrained rabbits.
MCEWEN, G. N.,JR., AND J. E. HEATH. Thermoregulatory responses to preoptic cooling in unrestrained rabbits. 227 (4) : 954-957. 1974.Rabbits at ambient temperatures within the thermal neutral zone show two different metabolic responses to preoptic cooling. One response type is defined by a preoptic thermal sensitivity that shifts with ambient temperature and a “set point” that remains constant. ...

Physiol. 214(4) : 843-850. 1968.-Abrupt bilateral cooling with a Peltier biothermode in the midpreoptic region of the ad lib. hydrated rhesus monkey produced a brisk water diuresis, elevation of plasma osmolality, warming of the arterial blood, cooling of the skin, shivering,...
متن کاملEvaluation of six cold-season turfgrasses responses to lead phytotoxicity for screening tolerant species
Lead (Pb) is one of the most hazardous heavy metal that caused serious problems for ecosystem at recent years. In this study, the effect of Pb on seed germination, incipient growth and antioxidant enzymes of six common used turfgrasses was investigated. The results showed that after implementation of different concentrations (0, 1000, 2000 and 3000 µM) of Pb, Agropyron elongatum exhibited the h...
متن کاملMetabolic responses of shorebird chicks to cold stress: hysteresis of cooling and warming phases.
We developed a protocol for determining the maximum rate of oxygen consumption of shorebird chicks (Scolopacidae and Charadriidae) in response to cold challenge. We first subjected the chicks to gradually decreasing temperatures until their metabolism peaked and began to decrease. We ended the cooling phase of a trial when a chick's body temperature T(b) had declined typically to 32-34 degrees ...
متن کاملHuman medullary responses to cooling and rewarming the skin: a functional MRI study.
A fall in skin temperature precipitates a repertoire of thermoregulatory responses that reduce the likelihood of a decrease in core temperature. Studies in animals suggest that medullary raphé neurons are essential for cold-defense, mediating both the cutaneous vasoconstrictor and thermogenic responses to ambient cooling; however, the involvement of raphé neurons in human thermoregulation has n...
