Modifying Effects of Lemongrass Essential Oil on Specific Tissue Response to the Carcinogen N-Methyl-N-Nitrosurea in Female BALB/c Mice
(Journal of Medicinal Food, 2012-02-01) [Artigo]
Lemongrass (Cymbopogon citratus Stapf) essential oil has been used worldwide because of its ethnobotanical and medicinal usefulness. Regarding its medicinal usefulness, the present study evaluated the beneficial effects ...
Chemically induced immunotoxicity in a medium-term multiorgan bioassay for carcinogenesis with Wistar rats
(Toxicology and Applied Pharmacology, 2004-01-15) [Artigo]
A variety of chemicals can adversely affect the immune system and influence tumor development. The modifying potential of chemical carcinogens on the lymphoid organs and cytokine production of rats submitted to a medium-term ...
Mushroom-derived preparations in the prevention of H2O2-induced oxidative damage to cellular DNA
(Teratogenesis Carcinogenesis and Mutagenesis, 2002-03-06) [Artigo]
Aqueous extracts of the sporophores of eight mushroom species were assessed for their ability to prevent H2O2-induced oxidative damage to cellular DNA using the single-cell gel electrophoresis (Comet) assay. The highest ...
Effects of diuron on toxicological and hematological parameters and lymphohematopoietic organs in a rat chemical hepatocarcinogenesis model
(Annual Review of Biomedical Sciences, 2005) [Artigo]
Effects of swim training on liver carcinogenesis in male Wistar rats fed a low-fat or high-fat diet
(Applied Physiology Nutrition and Metabolism = Physiologie Appliquee Nutrition Et Metabolisme, 2012-12-01) [Artigo]
The present study aimed to investigate the beneficial effects of swim training on the promotion-progression stages of rat liver carcinogenesis. Male Wistar rats were submitted to chemically induced liver carcinogenesis and ...
Probiotic Enterococcus faecium CRL 183 inhibit chemically induced colon cancer in male Wistar rats
(European Food Research and Technology, 2008-12-01) [Artigo]
Several animal studies have shown that supplementation with specific strains of lactic acid bacteria could prevent the establishment, growth, and metastasis of transplantable and chemically induced tumors. The goal of this ...
Potential effects of the herbicide Diuron on mammary and urinary bladder two-stage carcinogenesis in a female Swiss mouse model
(Archives of Toxicology, 2010-02-01) [Artigo]
The potential promoting effect of Diuron was investigated in a mouse model of mammary and urinary bladder carcinogenesis induced by 7,12-dimethylbenz(a)anthracene (DMBA) and N-butyl-N-(4-hydroxybutyl)nitrosamine (BBN). ...
Promotion of hepatocarcinogenesis by hexachlorobenzene in energy-restricted rats
(Cancer Letters, 2000-04-28) [Artigo]
The interaction between dietary energy restriction and low dose of the fungicide hexachlorobenzene (HCB) was evaluated in a rat liver medium-term bioassay for carcinogenesis. Male Wistar rats were fed a control or a 50% ...
Absence of chemopreventive influence of propolis on the rat liver altered foci development
(Experimental and Toxicologic Pathology, 2010-07-01) [Artigo]
Propolis (bee glue) is a complex mixture of natural substances that exhibits a broad spectrum of biological activities. As the possibility exists that it may exert a chemopreventive role against cancer development, the ...
Diuron lacks promoting potential in a rat liver bioassay
(Toxicologic Pathology, 2007-01-01) [Artigo]
The promoting activity of the herbicide Diuron was evaluated in a medium-term rat liver carcinogenesis bioassay that uses as endpoint immunohistochemically identified glutathione S-transferase positive (GST-P+) foci. Male ...
