Night time rectal temperature recordings were made from 103 infants sleeping in their own home in different sleeping positions. In most cases sleeping position was verified by video monitoring throughout the night. In the period before an adult-like night time body temperature pattern appeared there was no significant effect of sleeping position upon night time body temperature, in line with pr...

Respiratory rate (RR) and rectal temperature (RT) of seven crossbred, second-litter sows and 11 crossbred gilts and rates of sitting and standing activity of 10 sows and gilts were measured from about 109 days of gestation to 5 days after farrowing at thermoneutral (T, 20.5 C) or hot (H, 29.8 C) ambient temperatures. Respiratory rate and RT were higher in heat-stressed sows and gilts (P~.05) be...

Six Angus steers (319 +/- 8.5 kg) were assigned to one of two groups (hot or cold exposure) of three steers each, and placed into two environmental chambers initially maintained at 16.5-18.8 degrees C air temperature (Ta). Cold chamber Ta was lowered to 8.4 degrees C, while Ta within the hot chamber was increased to 32.7 degrees C over a 24-h time period. Measurements included respiration rate,...

Two nomograms are presented. The first enables the mean surface and body temperatures and the body heat content of a patient of given weight to be determined from measurements of skin temperature at three sites and of the core (rectal) temperature. The second enables the change in heat content of such a patient to be determined from the change in mean body temperature.

The aim of the study was to investigate pro-oxidant-antioxidant balance in two series of examinations with two types of stressors (exogenous heat and the combined exogenous and endogenous heat) in trained and untrained men. The exogenous stressor was provided by Finnish sauna session, whereas the combined stressor was represented by the exercise in elevated ambient temperature. The men from the...

Clinical and serum biochemical markers were utilized to assess the clinical efficacy of routinely used preanaesthetics induction agents in rabbits. Eight healthy rabbits (3.0-3.5kg) either sex randomly assigned one two groups: XK (Xylazine-ketamine) or XFK (Xylazine–fentanyl–ketamine). Intramuscular injections xylazine (5 mg/kg), ketamine (35 fentanyl (0.02 mg/kg) given parameters (rectal tempe...

The rectal temperature of 26 infants between 6 and 16 weeks old was monitored continuously for one night each week. Rectal temperature always decreased with sleep but the minimum temperature attained changed with age. Some time between 8 and 16 weeks old the minimum sleeping rectal temperature decreased abruptly from around 36.8 degrees C to around 36.4 degrees C. This change was complete withi...

TAYLOR, C. RICHARD, AND C. P. LYMAN. Heat storage in running antelopes: independence of brain and body temperatures. Am. J. Physiol. 222(l): 114-117. 1972.-Tremendous amounts of heat are produced when antelopes run at high speed. This study tried I) to determine how much of this heat was stored, and 2) to find out if antelopes possess unusual physiological mechanisms for coping with high body t...

This paper summarizes the findings from two recent studies involving the physiological effects of atropine (0 to 4 mg, im) on soldiers performing physical exercise in hot-dry environments. Study I determined the threshold of physiological effects and the gradation of these effects with increasing dosage of atropine. Study II examined the effects of exercise-heat acclimation on the reduced physi...

C.RF- Tshr(hyt/hyt) mice have a mutated thyroid-stimulating hormone receptor (TSHR), and, without thyroid hormone supplementation, these mice develop severe hypothyroidism. When hypothyroid Tshr(hyt/hyt) mice were exposed to cold (4 degrees C), rectal temperature rapidly dropped to 23.9 +/- 0.40 degrees C at 90 min, whereas the wild-type mice temperatures were 37.0 +/- 0.15 degrees C. When we c...
