Renal adaptation during hibernation.
Hibernators periodically undergo profound physiological changes including dramatic reductions in metabolic, heart, and respiratory rates and core body temperature. This review discusses the effect of hypoperfusion and hypothermia observed during hibernation on glomerular filtration and renal plasma flow, as well as specific adaptations in renal architecture, vasculature, the renin-angiotensin s...
متن کاملConserving energy during hibernation.
How hibernators manage to reduce their high metabolic rate – and therefore energy expenditure – from times when they are active to small almost immeasurable fractions during hibernation has attracted scientific inquiry for over a century. This problemwas also the subject of the classic study by Barbara D. Snapp and H. Craig Heller published in 1981, which presented detailed measurements of diff...

متن کاملThe kidney during hibernation and arousal from hibernation. A natural model of organ preservation during cold ischaemia and reperfusion.
BACKGROUND During hibernation the kidney is in a hypothermic condition where renal blood flow is minimal and urine production is much reduced. Periodical arousal from hibernation is associated with kidney reperfusion at increasing body temperature, and restored urine production rate. METHODS To assess the degree of structural preservation during such extreme conditions, the kidney cortex was ...
متن کاملUptake in Ground Squirrel Brain during Hibernation’
Autoradiographic patterns of [14C]2-deoxyglucose uptake are described throughout the brains of hibernating and euthermic ground squirrels. Autoradiographs of the brains of hibernating animals are generally homogeneous in comparison to euthermic animals; hence, the relative 2-deoxyglucose uptake (RBDGU) of gray to white matter for the majority of the 85 neural structures examined decreases durin...
