[Heat release and body temperature of white rats in the presence of increased oxygen tension].
Experiments were conducted on bodies warmed under constant regimen imitating animals; the effect of hyperoxybaria at 1.2--4.0 atmospheres on the heat flow (HF) from them and their temperature was studied. An increase of the recorded HF with its subsequent progressive decrease during the continuing exposure to high gas pressure was revealed. At the same time a fall of the bodies' temperature was observed; this indicated an increased heat loss. The periods of gas compression and decompression were accompanied by a marked increase and decrease of the HF, respectively. In experiments on albino rats alterations in the HF level under compression and decompression were less, and the HF level during the hyperbaria remained almost constant; the rectal and subcutaneous temperature showed no statistically significant difference from the original one. It is suggested that this may be the result of the thermogenesis rise.
