Diarrheal scores from experimental rats. Scores were obtained by checking for diarrhea daily by a trained veterinarian, 24 h after lactose intake by gavage, at the same time of the day for all groups. Scoring criteria accounted for changes in stool consistency and humidity, as follows: 0- normal stool consistency and dryness; 1-wet stools; 2-pasty stools; 3-semiliquid stools; 4-watery diarrhea.
