Alteration of stool in rhein-induced constipation of rats after administration with or without PEG4,000 for 30 d (%) .

Groups	Frequency of defecation (number/rat)	Fecal moisture (%)
Normal group (n = 12)	32.4 ± 5.6	56.88 ± 3.62
Model control group (n = 12)	18.2 ± 4.8	47.81 ± 3.98
PEG-treated group (n = 12)	20.6 ± 4.2^,	49.20 ± 3.27^,

Results are expressed as the mean ± standard deviation.  < 0.05, compared with normal group;  > 0.05, compared with model control group. PEG, polyethylene glycol.
