Comparisons of body weights, fecal trait grade scores of rats and colonic propulsion velocities in the four different groups following the drug intervention in vivo. A, Changes in the body weight of rats during drug intervention. B, Fecal traits of rats on the 4th day of drug intervention. C, Comparison of fecal trait grade scores during the drug intervention. D-G, Comparison of colonic propulsion velocity in four groups during 4 days of drug intervention. Compared with the 3rd day before drug intervention. H, Comparison of colonic propulsion velocities between the four groups of rats on the 4th day after in vivo drug intervention.
