Severely malnourished African infants are often feverish during hot summer weather. To elucidate the cause of this phenomenon, malnourished infants and controls were studied under standard conditions of heat stress with regard to sweat secretion and rise of body temperature. There was a marked impairment in the function of the sweat glands in the malnourished infants and the mean body temperature rose higher than that of the controls. The derangement of the sweat secretion was not related to the extent of the nutritional oedema. There was no close correlation between impairment of sweat secretion and rise in body temperature. The possible reasons for these observations are discussed. It is suggested that dysfunction of the sweat glands in severe malnutrition is caused by a poor peripheral circulation.

Maximum Work

Twelve subjects exercised to exhaustion at an ambient temperature of 18 degrees C on a bicycle ergometer with the load being stepwise increased. On one day, exercise was preceded by a precooling maneuver. In the precooling tests, deep body temperature attained values of about 1 degree C lower than in the control tests. There was no indication of metabolic cold defense reactions being evoked throughout the exercise period. In the precooling tests, heart rate was significantly lower than in the controls, but the mean maximum work rate, peak oxygen uptake (VO2), time to exhaustion, and total work were not reduced, i.e., work rate and VO2 were increased for a given heart rate. In the three subjects with the lowest maximum work rates, total work and exhaustion time and, in two cases, maximum work rate were increased after precooling. The onset of sweating occurred at higher work rates but at lower core, mean skin, and mean body temperature after precooling. However, the accumulated sweat secretion was considerably smaller after precooling, indicating less thermoregulatory effort.

The Difference

An experiment was performed to test the effect of solar radiation on the body temperatures of cattle, both clipped and with hair coat, in a clear transparent plastic covering as compared with cattle in a white reflective plastic covering. The mean body temperature of the animals in white plastic coats was 0.15°F lower than that of animals in clear plastic coats. This difference was highly significant statistically (P< 0.001). Animals in both clear and white coats had higher body temperatures than controls without plastic coats. The difference was highly significant, and was about 1.5°F in the clipped animals.

Eccrine Sweat

In humans, evaporative heat loss from eccrine sweat glands is critical for thermoregulation during exercise and/or exposure to hot environmental conditions, particularly when environmental temperature is greater than skin temperature. Since the time of the ancient Greeks, the significance of sweating has been recognized, whereas our understanding of the mechanisms and controllers of sweating has largely developed during the past century. This review initially focuses on the basic mechanisms of eccrine sweat secretion during heat stress and/or exercise along with a review of the primary controllers of thermoregulatory sweating (i.e., internal and skin temperatures). This is followed by a review of key nonthermal factors associated with prolonged heat stress and exercise that have been proposed to modulate the sweating response. Finally, mechanisms pertaining to the effects of heat acclimation and microgravity exposure are presented.

AbstractMean body temperature (TC) of Lacerta vivpara ranges from 26°8 to 32° at Paimpont (France). There is a highly significant correlation between environmental temperatures (TS) and body temperatures (TC). The mean body temperature of pregnant females is lower than that of males and non-pregnant females. Also, the regression line TC = f(TS) calculated for pregnant females is different from those calculated for males and non-pregnant females. The possible relations between pregnancy and body temperature are discussed.

Examination of the blood samples included RBCs count, Hb concentration, PCV % and values of cupper, magnesium, phosphorus, and potassium. The results showed that the mean body temperature of these goats was lower than in normal goats, while the respiratory and pulse rates were higher .Examination of blood revealed decrease in the means of RBCs counts ,Hb concentration and PCV % in the clinically diagnosed cases , and the decrease was more sever in local goats . However the results indicated lower values of cupper, magnesium, phosphorus, and potassium in comparison with normal values in goats. The ratio of cupper deficiency was the highest followed by phosphorus, magnesium and potassium and the ratio of malnutrition was high in Baghdad province. It was in Shammi breed higher than in local breed.

Eccrine Sweat

Conflicting reports exist about the role of baroreflexes in efferent control of eccrine sweat rate. These conflicting reports may be due to differing mean body temperatures between studies. The purpose of this project was to test the hypothesis that mean body temperature modulates the effect of head-up tilt on sweat rate and skin sympathetic nerve activity (SSNA). To address this question, mean body temperature (0.9·internal temperature + 0.1·mean skin temperature), SSNA (microneurography of peroneal nerve, n = 8), and sweat rate (from an area innervated by the peroneal nerve and from two forearm sites, one perfused with neostigmine to augment sweating at lower mean body temperatures and the second with the vehicle, n = 12) were measured in 13 subjects during multiple 30° head-up tilts during whole body heating. At the end of the heat stress, mean body temperature (36.8 ± 0.1 to 38.0 ± 0.1°C) and sweat rate at all sites were significantly elevated. No significant correlations were observed between mean body temperature and the change in SSNA during head-up tilt ( r = 0.07; P = 0.62), sweating within the innervated area ( r = 0.06; P = 0.56), sweating at the neostigmine treated site ( r = 0.04; P = 0.69), or sweating at the control site ( r = 0.01; P = 0.94). Also, for each tilt throughout the heat stress, there were no significant differences in sweat rate (final tilt sweat rates were 0.69 ± 0.11 and 0.68 ± 0.11 mg·cm−2·min−1 within the innervated area; 1.04 ± 0.16 and 1.06 ± 0.16 mg·cm−2·min−1 at the neostigmine-treated site; and 0.85 ± 0.15 and 0.85 ± 0.15 mg·cm−2·min−1 at the control site, for supine and tilt, respectively). Hence, these data indicate that mean body temperature does not modulate eccrine sweat rate during baroreceptor unloading induced via 30° head-up tilt.
