Abstract

We aimed to investigate whether infra red thermography (IRT) can be used to measure and quantify non-shivering thermogenesis (NST) in the short-tailed field vole Microtus agrestis, by directly comparing it with a standard method, i.e. metabolic response following Noradrenaline injection (NA). Mean skin surface temperature overlying Brown adipose tissue (BAT) depot was 0.82 degreesC higher than mean surface temperature that did not overly BAT. The difference in temperature increased by 1.26 degreesC after NA was administered. Mean skin surface temperature overlying BAT increased by 0.32 degreesC after NA was administered; however, surface temperature decreased by 1.32 degreesC after saline was administered. Mean skill surface temperature overlying BAT did not change significantly between warm and cold acclimated voles; in contrast metabolic peak following NA injection significantly increased in cold acclimated voles. There was no significant correlation betweenchange in surface temperature after NA injection and metabolic peak following NA injection. The results of this study suggest that IRT is not a sensitive enough method to measure changes in NST capacity in BAT following NA injection, or to detect changes in NST capacity induced by cold acclimation. However, IRT call distinguish between skin surfaces overlying BAT and skinsurfaces that do not. (C) 2001 Elsevier Science Ltd. All rights reserved.
