Research Abstract |
This study was conducted in Ani Mataginosato Bear Park, Kitaakita-shi, Akita Prefecture in order to know why obese bears do not suffer fatty liver even though they get 30-40% fat of body weight and to investigate a feature mechanism for accumulation of body fat. Under anesthetized condition, measurements of blood concentrations of carbohydrate and fat, intravenous glucose tolerance tests and adipose tissue biopsies were performed for this study. As results, it is concluded that increase of body fat accumulation during pre-hibernation period is controlled by physiological and metabolic mechanism as well as hyperphagia in Japanese black bears
