Fig. 1. Net water absorption rates in rats exposed for 6 days to either a cathartic mixture (PC), the same containing 10 g/L of GA (GA1), or 20 g/L GA (GA1). Control rats (CTL) were offered water, or water with 20 g/L GA (CTL + GA). Brackets represent the SEM. N = 14 for each group. The lettering on the bar signifies that those not sharing a letter are different (p < 0.05).
