Effect of catalpol on food consumption of rats. After given high-fat high-sugar food for 3 weeks, and STZ induced STZ-fat-diabetic rats successfully for 3 weeks, a solution of catalpol at 50 mg/kg or the same volume of vehicle was injected intravenously into rats. Changes of food intake at the indicated time point were compared between the catalpol-treated group (solid circles) and the vehicle-treated group (open circles). Values (mean ± SD) of each group were obtained from eight animals. *P < 0.05 as compared with vehicle-treated group at the same time
