title: Effects of an aqueous extract of Triticum repens on lipid metabolism in normal and recent-onset diabetic rats.
abstract: The aim of this study was to demonstrate the effects of single and repeated oral administration of the aqueous rhizomes extract of Triticum repens (TR) (20 mg/kg) on lipid metabolism in normal and streptozotocin-induced diabetic rats. In normal rats, the aqueous extract of TR induced a significant decrease in the plasma triglycerides concentrations 4 days (P<0.05) and 1 week after repeated oral administration (P<0.05). This reduction was abolished 2 weeks after once daily repeated oral administration. A significant decrease of plasma cholesterol levels was observed only 1 week (P<0.05) after repeated oral administration. In diabetic rats, TR treatment caused a significant decrease in plasma triglycerides levels after a single (P<0.01) and repeated (P<0.001) oral administration. A strong decrease in cholesterol level was observed 6 h after a single oral administration of the aqueous extract TR (P<0.001). Four days after repeated oral administration of TR aqueous extract, the plasma cholesterol level was significantly decreased (P<0.05) and still dropped after 2 weeks (P<0.001). On other hand, the repeated oral administration of aqueous TR extract caused a significant decrease in body weight 2 weeks after repeated oral treatment in diabetic rats (P<0.05). We conclude that the aqueous extract of TR exhibits lipid and body weight lowering activities in severe hyperglycaemic rats after repeated oral administration of aqueous TR extract at a dose of 20 mg/kg.
