1. The inclusion of phytate (10 g/kg) in a purified diet containing zinc (15 mg/kg) fed to young male rats significantly reduced growth rate and food intake, and promoted a cyclic pattern of food intake characteristic of an uncomplicated Zn deficiency. The decreased growth rate could be accounted for by the reduced food consumption. 2. Rats maintained on a Zn-deficient diet (0.5 mg Zn/kg) were ...

Iron has been proposed as influencing the progression of liver disease in subjects with non-alcoholic fatty (NAFLD). We have previously shown that, Hfe−/− mouse model hemochromatosis, feeding a high-calorie diet (HCD) leads to increased injury. In this study we investigated whether an iron deficient/HCD mice influenced development NAFLD. Liver histology was assessed fed standard iron-containing...

By ALFRED GELLHORN, M.D., AND LOGAN 0. JONES, M.D. E VIDENCE from animal experimentation indicates that pyridoxine, a cornponent of the vitamin B complex, is an essential factor for the maintenance and function of hematopoietic tissue. Severe anemia has been induced in dogs’ and swine2 on a pyridoxine deficient diet and the integrity of lymphoid tissue in rats has also been demonstrated to be d...

Abstract The effectiveness of calcium depends on its source, i.e., salt it is supplied with. This study aimed to determine the effects lactate in diet inflammation and oxidative stress markers ovariectomized rats. A total 40 female Wistar rats were included this study, which divided into four groups. control group was fed a standard diet, whereas remaining three groups provided containing carbo...

An experiment was conducted to examine the effects of adding microbial phytase (Natuphos) on the performance in broilers fed a phosphorus-adequate, lysine-deficient diet. A wheat-soybean meal-sorghum-based diet, containing 1.00% lysine and 0.45% nonphytate phosphorus, was supplemented with L-lysine monochloride to provide 1.06, 1.12, or 1.18% lysine or with 125, 250, 375, 500, 750, or 1,000 phy...

Female B/W mice spontaneously develop an autoimmune disease that is similar to systemic lupus erythematosus. Antibodies to doublestranded DNA (dsDNA) and antinuclear antibodies develop in aging animals; death from immune complex-mediated glomerulonephritis occurs from 8 to 12 mo of age. It has been reported that prostaglandin (PG)E(1) treatment of such mice prolongs survival. In the present stu...

The effect of methotrexate on lipids in serum and liver and key enzymes involved in esterification and oxidation of long-chain fatty acids were investigated in rats fed a standard diet and a defined choline-deficient diet. Hepatic metabolism of long-chain fatty acids were also studied in rats fed the defined diet with or without choline. When methotrexate was administered to the rats fed the st...

Several oxidative stressors (dietary selenium deficiency, dietary vitamin E deficiency coupled with fish oil feeding, genetic reduction of glutathione peroxidase activity) allow a normally benign coxsackievirus B3 (CVB3/0) to damage heart muscle in host mice. This study investigated whether dietary iron overload, another oxidant stress, would also permit CVB3/0 to exert a cardiopathologic effec...

The effects of high-fat feeding on the development of obesity were evaluated in intercellular adhesion molecule-1 (ICAM-1) knockout and C57BL/6J (B6) male mice fed a high-fat diet for < or =50 days. Serum and tissues were collected at baseline and after 1, 11, and 50 days on the diet. After 11 days on the diet, ICAM-1-deficient, but not B6, mice developed fatty livers and showed a significant i...

This study aims to evaluate the effects of diets deficient in choline and/or cystine on hepatocellular injury in animal models (young male Wistar rats, aged 21 days), by monitoring some of the oxidative stress biomarkers and the expression of RAGE, TNF-α, and IL-1β. The animals were divided into 6 groups (n = 10) and submitted to different diets over 30 days: AIN-93 diet (standard, St), AIN-93 ...
