Heat and cold acclimation in helium-cold hypothermia in the hamster.

摘要: A study was made of the effects acclimation hamsters to high (34-35 C) and low (4-5 temperatures for periods up 6 weeks on induction hypothermia in hamsters. Hypothermia achieved by exposing a helox mixture 80% helium 20% oxygen at 0 C. Hypothermic most rapid (2-3 hr) heat-acclimated slowest (6-12 cold-acclimated The period intermediate (5-8 room temperature nonacclimated animals (controls). Survival time relatable previous acclimations. hypothesis that thermogenesis would accentuate resistance substantiated.
