Effects of food restriction on mice with the hereditary obese-hyperglycemic syndrome. 1979

J M Feldman, and J A Blalock, and L B Foster

The purpose of this study was to compare the organ weights of obese-hyperglycemic (ob/ob) mice with the organ weights of their normal litter-mates. The absolute weights of the epididymal fat pads (white fat), interscapular fat pads (brown fat) and liver were greater in ob/ob mice than in normal mice. The weights of the kidneys and heart were similar in the 2 groups. The weights of the brain and testes were decreased in ob/ob mice when compared with normal mice. The weight gain of a second group of ob/ob mice was decreased by chronic food restriction resulting in a 26% reduction in weight when compared with ob/ob mice having unrestricted access to food. This substantially reduced the weight of the liver, but resulted in a minimal reduction in the weight of the epididymal fat pad. Food restriction did not alter the weight of the interscapular fat pads. It caused a relative reduction in kidney weight and a further absolute and relative reduction in testis weight.

D009929	Organ Size	The measurement of an organ in volume, mass, or heaviness.	Organ Volume,Organ Weight,Size, Organ,Weight, Organ
D001835	Body Weight	The mass or quantity of heaviness of an individual. It is expressed by units of pounds or kilograms.	Body Weights,Weight, Body,Weights, Body
D001921	Brain	The part of CENTRAL NERVOUS SYSTEM that is contained within the skull (CRANIUM). Arising from the NEURAL TUBE, the embryonic brain is comprised of three major parts including PROSENCEPHALON (the forebrain); MESENCEPHALON (the midbrain); and RHOMBENCEPHALON (the hindbrain). The developed brain consists of CEREBRUM; CEREBELLUM; and other structures in the BRAIN STEM.	Encephalon
D004822	Epididymis	The convoluted cordlike structure attached to the posterior of the TESTIS. Epididymis consists of the head (caput), the body (corpus), and the tail (cauda). A network of ducts leaving the testis joins into a common epididymal tubule proper which provides the transport, storage, and maturation of SPERMATOZOA.
D005508	Food Deprivation	The withholding of food in a structured experimental situation.	Deprivation, Food,Deprivations, Food,Food Deprivations
