Recurring evidence suggests that social stress has anxiogenic-like effects in laboratory rodents. However, despite the fact that competitive situations are stressful, success in competitive situations reduces anxiety in humans. The aim of the present study was to investigate whether repeated experie

β¦ Synopsis
The effect of Monascus purpureus red mould rice (RMR) on modulation of lipid metabolism and oxidative stress was studied in hypercholesterolemic rats. Cholesterol feeding for 14βweeks caused a significant increase in the lipid peroxides and total thiols and antioxidant enzymes, viz. glutathione peroxidase (GPx), glutathione reductase (GRd), superoxide dismutase (SOD) and catalase (CAT) in serum and liver in comparison to the control group. However, supplementation of RMR to hypercholesterolemic rats at 8, 12 and 16% significantly increased the GRd, GPx, SOD and CAT activities in serum and liver tissues. Furthermore, RMR feeding significantly decreased total thiols and lipid peroxides and also increased other antioxidant molecules such as glutathione and ascorbic acid in highβcholesterol fed rats. The efficiency of RMR (16%) in modulating the antioxidant molecules and antioxidant enzymes is comparable to standard drugβlovastatin. Thus, this study suggests that the longβterm administration of RMR may play an important role in suppressing oxidative stress and, thus, may be useful for the prevention and/or early treatment of hypercholesterolemia.
