Effects of a high fructose diet on lipogenic enzyme activities in some organs of rats fed ad libitum. 1975

Y Sugawa-Katayama, and N Morita

The effect of a high fructose diet on lipogenesis was studied in rats. Male and female rats were divided into three groups and were fed a high carbohydrate diet ad libitum for 4 days: group 1 was fed a high cornstarch diet, group 2 was fed a high fructose diet without starvation, and group 3 was fed a high fructose diet after 2 days of starvation. The activities of lipogenic enzymes, i.e., glucose-6-phosphate dehydrogenase and malic enzyme were assayed in liver, adipose tissue, and small intestine. The lipid content of liver was also determined. On day 4, the lipid content of group 1 was about 45 mg, that of group 2 was about 70 mg, and that of group 3 was about 115 mg (female) and 145 mg (male) per gram of wet weight. Groups 2 and 3 showed significantly higher activity of hepatic malic enzyme than group 1. The activity of intestinal malic enzyme was highest in group 1 and not significantly different between groups 2 and 3. The malic enzyme activity in adipose tissue of females of group 3 was higher than that in either sex of the other groups.

D009929	Organ Size	The measurement of an organ in volume, mass, or heaviness.	Organ Volume,Organ Weight,Size, Organ,Weight, Organ
D010053	Ovary	The reproductive organ (GONADS) in female animals. In vertebrates, the ovary contains two functional parts: the OVARIAN FOLLICLE for the production of female germ cells (OOGENESIS); and the endocrine cells (GRANULOSA CELLS; THECA CELLS; and LUTEAL CELLS) for the production of ESTROGENS and PROGESTERONE.	Ovaries
D004040	Dietary Carbohydrates	Carbohydrates present in food comprising digestible sugars and starches and indigestible cellulose and other dietary fibers. The former are the major source of energy. The sugars are in beet and cane sugar, fruits, honey, sweet corn, corn syrup, milk and milk products, etc.; the starches are in cereal grains, legumes (FABACEAE), tubers, etc. (From Claudio & Lagua, Nutrition and Diet Therapy Dictionary, 3d ed, p32, p277)	Carbohydrates, Dietary,Carbohydrate, Dietary,Dietary Carbohydrate
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.
