Effects of AEtLP on stool and urine secretion in Lop-induced constipated rats. Stool number (A), stool weight (B), and urine volume (D) were measured immediately using an electric balance and measuring cylinder. Water content of stools (C) was determined by drying stools for 12 h. Five to six rats per group were assayed in triplicate for excretion analysis. Data represent the mean ± SD from three replicates. a, p < 0.05 compared to the No-treated group. b, p < 0.05 compared to the AEtLP-treated group. c, p < 0.05 compared to the Lop + vehicle-treated group.
