Analysis of variance showed that female Harlan Sprague-Dawley rats treated with E in combination with P (EP) had a significantly higher rectal temperature (Tre) than untreated control animals and those treated with E or P alone. In E treated rats, Tre was significantly higher than control animals and those treated with P; All treatment groups had a significantly lower tail skin temperature as compared to the control animals. The rise in Tre in E and EP treated rats did not appear to result from an increase in metabolism since the rates of oxygen consumption did not differ significantly with hormone treatment. The rise in Tre of E and EP treated rats may have resulted from a decrease in heat loss as evidenced by the lower tail skin temperatures. Hormonal treatment did not impair the animal's thermoregulatory responses during acute heat and cold exposure. However, body weight was highest in P treated rats. The body weight of EP treated rats was also greater than the control animals and those treated with E alone.
