Brown Adipose Tissue Thermogenesis

This study was carried out to investigate the nutritional energetics of ovariectomized rats with or without ovarian hormone replacement. Rats were divided into five groups: 1) sham operated, 2) ovariectomized, 3) ovariectomized and treated with progesterone, 4) ovariectomized and treated with estradiol, or 5) ovariectomized and treated with estradiol and progesterone. After 36 days of treatment, energy contents of all five groups were determined together with energy content of food and feces. Brown adipose tissue thermogenesis was assessed through mitochondrial GDP binding assay. Results show that ovariectomy leads to a 16% increase in metabolizable energy intake. This increase was accompanied by a twofold increase in body energy gain. Progesterone did not further affect energy intake and gain in ovariectomized rats. However, increases in both food intake and energy gain were prevented by the estradiol replacement therapy. There was no difference in energy expenditure between sham-operated and ovariectomized rats in the absence of estradiol. In estradiol-treated animals, energy expenditure (kJ.kg body wt-0.75 . day-1) showed a slight increase. There was no difference in protein content of interscapular brown adipose tissue between all five groups. GDP binding was slightly reduced in ovariectomized estradiol-treated rats. It is concluded from this study that ovarian hormones produce their effects on energy balance mainly by altering food intake.

Brown Adipose Tissue Thermogenesis

The effects of continuously administered endotoxin on 7-day energy balance were investigated in male rats. Three groups of rats were implanted with osmotic pumps; two groups received saline-filled pumps, whereas the third received endotoxin. One of the saline groups was pair fed to match the food intake of the endotoxemic rats. After 7 days, body energy and protein and fat contents of rats were determined together with the energy content of food and feces. Endotoxin infusion not only induced fever, but it also suppressed appetite and significantly decreased body weight gain. Metabolizable energy intake was reduced by approximately 20% in infected rats. Although protein and fat gains were lowest in the endotoxin group, there appeared to be a selective loss of protein when considered as percent of body weight. Percent body fat was unaltered between the groups. Energy expenditure considered in absolute (kJ) or body weight-independent (kJ/kg0.67) terms yielded similar patterns of results; expenditure (kJ) was 10 and 20% (P less than 0.05, P less than 0.01) lower in the endotoxemic and pair-fed rats, respectively, compared with controls. Hence, compared with pair-fed rats, endotoxin-infused animals had a 10% rise in their expenditure. Brown adipose tissue thermogenesis was assessed by mitochondrial binding of guanosine 5′-diphosphate, and results showed that binding was greatest in endotoxemic rats and lowest in the pair-fed animals. The present results suggest that in this endotoxemic model appetite suppression exacerbates changes in energy balance. However, the reduction in body weight gain is also dependent on a decrease in metabolic efficiency and an increase in total energy expenditure.(ABSTRACT TRUNCATED AT 250 WORDS)
