Abstract
(1) Male Wistar, and Zucker (lean and obese) rats aged 7 weeks of age were divided into three groups, warm acclimated (25 degreesC for 11 weeks). cold acclimated (10 degreesC for 11 weeks). and deacclimated (10 degreesC for 9 weeks and 25 degreesC for 2 weeks) groups. (2) Density of lipid droplet in brown adipose tissue (BAT) of obese rats was the greatest and that in lean rats was less than that in Wistar rats. (3) Mass of brown adipose tissues (BATM) per body mass (BM) was greater in obese rats than lean rats. (4) Mar ked weight-reducing effect observed in obese rats during cold acclimation i s partly resulted from greater BATM/BM. (C) 2001 Elsevier Science Ltd. All rights reserved.
