Q LORIC BALANCE depends upon the regulation of biologic energy exchange. Four important variables are concerned in energy balance : ( 1) food intake, (2) energy storage, (3) energy utilization through activity or work and (4) loss of energy in the production of heat. The caloric balance would thus be regulated by the various mechanisms which regulate the caloric intake in the form of food intak...

Our knowledge of the physiological systems controlling energy homeostasis has increased dramatically over the last decade. The roles of peripheral signals from adipose tissue, pancreas, and the gastrointestinal tract reflecting short- and long-term nutritional status are now being described. Such signals influence central circuits in the hypothalamus, brain stem, and limbic system to modulate n...

introduction: ghrelin increases growth hormone secretion and food intake. growth hormone (gh), steroid hormones and opioids are involved in the regulation of food intake. so, they may have a role in the regulation of ghrelin secretion. we determined the effect of intravenous injections of progesterone, gh and morphine or co-administration of these hormones on ghrelin concentration and body weig...

Background: Feeding behavior is regulated by a complex network which interacts via diverse signals from central and peripheral tissues. It is known dopaminergic and glutamatergic systems have crucial role on food intake regulation but scarce reports exist on their interaction in appetite regulation in broilers. OBJECTIVES: The present study was designed to examine the role of glutamatergic syst...

BACKGROUND Anorexia is a common symptom among cancer patients and contributes to malnutrition and strongly impinges on quality of life. Cancer-induced anorexia is thought to be caused by an inability of food intake-regulating systems in the hypothalamus to respond adequately to negative energy balance during tumour growth. Here, we show that this impaired response of food-intake control is like...

Regulation of food intake is a term which includes all of the reactions through which an animal (i) maintains a constant intake while environmental and metabolic conditions are constant, and (ii) adjusts its intake whenever environmental or metabolic conditions are altered. What an animal eats and how much are usually thought to be determined by the energy requirements of the body; but every ca...
