Description:
Mammals normally maintain their core body temperature (CBT) despite changes in environmental temperature. Exceptions to this norm include suspended animation-like states such as hibernation, torpor, and estivation. These states are all characterized by marked decreases in metabolic rate, followed by a loss of homeothermic control in which the animal's CBT approaches that of the environment. We report that hydrogen sulfide can induce a suspended animation-like state in a nonhibernating species, the house mouse (Mus musculus). This state is readily reversible and does not appear to harm the animal. This suggests the possibility of inducing suspended animation-like states for medical applications.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Blackstone, Eric -- Morrison, Mike -- Roth, Mark B -- GM48435/GM/NIGMS NIH HHS/ -- T32 AG00057/AG/NIA NIH HHS/ -- New York, N.Y. -- Science. 2005 Apr 22;308(5721):518.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Molecular and Cellular Biology Program, University of Washington, Seattle, WA 98195, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/15845845" target="_blank"〉PubMed〈/a〉
