| ABSTRACT Quercetin has potent antioxidant action and a hepatoprotective role. The aim of this study was to evaluate the hepatoprotective action of quercetin pretreatment in paracetamol-induced liver damage (PILD) and structural injury resulting from partial hepatectomy (PH). In the first model, Wistar rats received oral quercetin (50mg/kg/day) during 8 days. On the 8th day, 3g/kg paracetamol were added. In the second model, the same quercetin dose was given during 7 days and rats were submitted to PH on the 8th day. Blood samples were obtained for determination of enzyme levels. Liver, heart, kidney and lung tissue were also collected for assessment of quercetin biodistribution and/or histological analyses. The results obtained after PILD were more... |

| Curcuma longais a ginger family aromatic herb (Zingiberaceae) whose rhizomes contain curcuminoid pigments, including curcumin, a compound known for its anti-inflammatory effects. The objective of this study was to obtain curcuminoid-rich extracts, develop topical formulations thereof, and assess the stability and skin permeation of these formulations. Curcuma longa extracts were obtained and used to develop formulations. Skin permeation studies were conducted in a modified Franz diffusion cell system, and skin retention of curcuminoid pigments was quantified in pig ear membrane. Prepared urea-containing gel-cream formulations were unstable, whereas all others had satisfactory stability and pseudoplastic rheological behavior. The amount of curcuminoid... |
