Bisphenol A (BPA) is an estrogenic environmental toxicant, a synthetic monomer widely used to polymerize polycarbonate plastics and resins. BPA has been implicated to have hazardous effect on reproductive health in human and experimental rats. Lycopene is a powerful antioxidant and potential high-value compound for the prevention of many diseases. The present study has been designed to investig...

In this study, we investigate the immunostimulatory effects of alcoholic extract of the coffee seed on cell-mediated immune response and cyclophosphamide-induced (CP) immunosuppressed mice. The assessment of cellular immune function was carried out by the measurement of delayed-type hypersensitivity (DTH) response. According to the literature survey, cyclophosphamide has only suppressing effect...

PURPOSE To evaluate the activity of palifermin (rHuKGF) in a murine model of mucosal damage induced by a radiotherapy/chemotherapy (RT/CT) regimen mimicking treatment protocols used in head-and-neck cancer patients. METHODS AND MATERIALS A model of mucosal damage induced by RT/CT was established by injecting female BDF1 mice with cisplatin (10 mg/kg) on Day 1; 5-fluorouracil (40 mg/kg/day) on...

OBJECTIVE This study was conducted to investigate the effect of dietary onion (Allium cepa) extract (OE) supplementation on growth performance, apparent total tract retention (ATTR), blood profile, carcass characteristics and meat quality in broilers. METHODS Four hundred male broiler chicks (Ross 308, 3-d old) were randomly allocated to four dietary treatments for 28 d feeding trial. Each tr...

BACKGROUND The increasing use of complementary and alternative medicine (CAM) has kindled the need for scientific evaluation of the mechanism of action of CAMs. Although, licorice, a common ingredient in many Traditional Chinese medicine (TCM) has attracted great attention for its antitumor and immunomodulatory activities, the mechanism of action of its polysaccharides is still unclear. Here we...

The role of immune system is to sustain host defense mechanisms and maintain homeostasis. The immune system maintains a constant surveillance against invading pathogenic microorganisms, Immunomodulation may involve either an increase in the magnitude of immune response i.e. immunostimulation or a decrease in the magnitude of the immune response i.e. immunosuppression. Long acting oxytetracyclin...

Rat pups were artificially reared (AR) from postnatal day 4 or 5 till day 20 or 21, by fitting them with gastric cannulas through which milk-substitutes could be infused automatically. Three milk-substitutes were compared: milk M, the usual diet for AR studies, which was somewhat low in protein and very high in carbohydrate; milk A, which resembled rats' milk much more closely in composition; a...

BACKGROUND This study was designed to evaluate the safety of PolyGlycopleX (PGX), a novel viscous dietary polysaccharide (fiber), when administered to Sprague Dawley(R) rats in the diet for 90 days. METHODS Groups of ten male and ten female rats each consumed PGX mixed in the diet at levels of 0, 1.25, 2.5 or 5.0% for 90 days, then evaluated for toxicological effects on parameters that includ...

In November, 1921, a systematic study of normal rabbits was undertaken as a part of a more general investigation dealing with the subject of the animal organism in relation to disease. The present paper on organ weights is based on results obtained from a study of 350 male rabbits killed and examined between January 1, 1922, and July 1, 1924. Methods of conducting the experiments are described ...
