alters body-core temperature response to a simulated open field in rats. J. Appl. Physiol. 82(4):
1406-1410, 1997.
Exposure of a rat to a novel environment (e.g.,
a simulated open field) induces a transient increase in body-core
temperature, which is often called stress-induced hyperthermia.
Although pregnancy is known to influence thermoregulatory control, its
effect on stress-induced hyperthermia is unknown. Therefore, 24 Sprague-Dawley rats (8 nonpregnant and 16 pregnant) were studied to
test the hypothesis that pregnancy would alter the development of
stress-induced hyperthermia after exposure to a simulated open field.
Body-core temperature index increased significantly after exposure to a
simulated open field in nonpregnant and gestation
day-10 rats but not in gestation day-15 and
day-20 rats. Thus our data provide
evidence that pregnancy influences the body-core temperature response
of rats exposed to a simulated open field in a gestation-dependent
fashion. The functional consequences as well as the mechanisms involved
remain to be determined.
