Two kinds of radiopaque pellets were ingested as markers to determine GITT in 60 normal subjects, 7 patients with ulcerative colitis (UC), 10 patients with idiopathic constipation (IC) and 8 patients with other diseases. The food contained 10-20g dietary fiber per day. Besides, GITT was determined in 14 normal subjects whose dietary content was 40-50g or 10g MO YU and 10-20g dietary fiber per day. Results are expressed in hours as 50% transit time (mean +/- s) and the values or normal subjects are as the follows: total GITT 25.0 +/- 7.3h, mouth iteum TT 9.0 +/- 3.3h, colonic TT 15.9 +/- 7.5h. There was no difference in age or sex groups. However, in high dietary fiber or MO YU group, GITT shortened significantly. Abnormal GITT was shown in patients with UC, IC, other gut and systemic diseases. In conclusion, the method employed in the present study is simple, safe and useful in the clinical study of gastrointestinal motility; and may provide important information to elucidate the pathophysiology of the diseases related to disorders in motility of the digestive tract.
