Velhas tardes de domingo (Notas sobre DomingaÌo do FaustaÌo e Programa Silvio Santos)
Nas tardes de domingo,as duas maiores redes de televisaÌo brasileiras apresentam programas de auditoÌrio: a Rede Globo de TelevisaÌo transmite DomingaÌo do FaustaÌo e o Sistema Brasileiro de TelevisaÌo veicula o Programa Silvio Santos. Este estudo traça um breve histoÌrico desses dois programas, descreve rapidamente suas estruturas, e, a partir daiÌ, delineia hipoÌteses sobre possiÌveis funçoÌes desses produtos televisivos junto aos espectadores.
Hypolipidemic action of chrysin on Triton WR-1339-induced hyperlipidemia in female C57BL/6 mice
Chrysin (5,7-dihydroxyflavone) is a flavonoid, natural component of traditional medicinal herbs, present in honey, propolis and many plant extracts. The objective of this study was to investigate the hypolipidemic properties of chrysin on Triton WR-1339-induced hyperlipidemia in female C57BL/6 mice. Triton WR-1339 was administered intraperitoneally (400 mg/kg) to overnight-fasted mice to develop acute hyperlipidemia. Chrysin was administered orally (10 mg/kg) 30 min before Triton WR-1339. At 24 h after Triton WR-1339 injection, blood samples were collected to measure plasma lipid levels. The hepatic thiobarbituric acid reactive substances (TBARS), carbonyl content, non-protein sulfhydryl (NPSH) and ascorbic acid (AA) levels, as well as catalase (CAT) and superoxide dismutase (SOD) activity were recorded. Chrysin administration significantly decreased total cholesterol levels. In addition, it partially decreased non-high density lipoprotein-cholesterol and triglycerides levels in plasma of hyperlipidaemic mice. In addition chrysin administration prevented the increase on TBARS levels and prevented the decrease in SOD activity induced by Triton WR-1339. These findings indicated that chrysin was able to decrease plasma lipids concentration and that its antioxidant properties was, at least in part, involved in the hypolipidaemic action of chrysin
