Two nutritional models, an essential fatty acid deficiency model and the feeding of saturated versus unsaturated fats, were used in a feeding study in order to assess the relationship between tissue fatty acid composition and the activities of some membrane-associated enzymes. Purified diets

The effects of incorporation of dietary n-3 polyunsaturated fatty acids (PUFA) into rat liver plasma membrane on the activity of 5'-nucleotidase (EC 3.1.3.5) was studied. The membrane phospholipids from rats fed a diet containing 10% by weight menhaden oil (MO) for 3 wk contained more n-3 PUFA and

Tod determine whether changes in unsaturation of fatty acids in rat liver plasma membranes might alter activities of membrane-associated enzymes, liver plasma membranes were prepared from rats fed purified diets lacking or supplemented with essential fatty acids. Two methods of membrane purification

In one experiment Swiss mice were maintained on a 16 or 23% fat diet (laboratory chow with added fat, principally corn oil) or on laboratory chow alone (5.5% fat). In another experiment C57BL/1 mice were given a 23% fat diet (as above) or a low-fat diet (67% laboratory chow, 1.9% corn oil, and 31%

This study investigated the effect of eugenol on arginase, nucleotidase and adenosine deaminase activities in platelets of carrageenan-induced arthritic rat model to explain a possible anti-arthritic mechanism of eugenol. Fifty adult female rats (140-250 g) were divided into ten (10) groups (n = 5).

Intestinal alkaline phosphatase (IAP) is a brush-border membrane ectoenzyme (BBM-IAP) that is released into the lumen (L-IAP) after a high-fat diet. We examined the effects of oil feeding and the addition of mixed-lipid micelles on the formation of L-IAP in oil-fed rat intestine, Caco-2 cell

Chlordecone (CD) impairs biliary excretion of organic anions (including phenolphthalein glucuronide (PG), imipramine polar metabolites, and taurocholate) without evidence of hepatocellular necrosis in rats. In this study we investigated the hypothesis that CD-induced hepatobiliary dysfunction is

Previous results in male Sprague-Dawley rats indicate that acetone (A), methyl ethyl ketone (MEK), and methyl isobutyl ketone (MiBK) pretreatments (3 d, p.o.) at a dosage of 6.8 mmol/kg potentiate CCl4 hepatotoxicity. The potentiation potency profile observed was MiBK > A > MEK. In the present

Composition of diet may influence growth, diseases, tumor rates, and responses to chemical treatment. Since 1980 the NIH-07 open formula nonpurified diet has been the selected diet for the National Toxicology Program (NTP) toxicity and carcinogenicity studies in rodents. Studies with nonpurified

The aim of the present study was to investigate the effect of curcumin (Cur) on the activity of ectonucleoside triphosphate diphosphohydrolase (CD39), 5'-nucleotidase (CD73) and adenosine deaminase in platelets of cigarette smoke-exposed rats. For that purpose, we subjected male Wistar rats to a

Vascular disease is a major cause of morbidity and mortality among transplanted recipients and cyclosporine (CsA) treatment has been consistently implicated in this event. In this study we assessed total blood homocysteine levels (tHcy), ecto-nucleotidase activities and adenine nucleotide/nucleoside

Lung cancer is one of the leading causes of cancer death in the world and is notoriously difficult to treat effectively. In the present study, male Swiss albino mice were divided into five groups of six animals each: group I animals received corn oil orally and served as a control; group II

The importance of estrogens in the dietary lipid alteration of R3230AC mammary carcinoma growth and insulin binding was studied. Animals were divided into three groups [intact, ovariectomized, and ovariectomized treated with estradiol valerate (EV)] and were fed diets containing either 0% fat (fat

Female Swiss mice were fed on a control diet (laboratory chow, 6% fat) or high fat diets (laboratory chow with added fat, principally corn oil, to produce a fat content of 16% or 23%). Homogenate of colon mucosa was fractionated by isopycnic banding on a linear sucrose gradient and the distribution
