[The development of a thermoregulatory reaction to heat emission in ontogeny in rats].
The temperatures of rectum, under back and tail skin in 6-15-days-old, 17-25-days-old and adult rats during warm environment were measured. It was obtained that the vasomotor reaction exists in 17-25-days-old rat pups, but not in 6-15-days-old pups.
