The hydrogen breath test was performed in 35 Korean healthy adults by ingestion of 18 g lactose and analysis of end-expiratory air. The results were as follows; 1) Of the 35 subjects, 13 had symptoms and an increase in breath H₂ concentration of ≥20 p,p.m. at some interval during 5 hours collection period after oral 18 g lactose load. (Lactose intolerants) 2) The other 22 subjects did not have an maximal increase of ≥20 p.p.m. although 3 subjects had an increase of 71, 24 and 22 p.p.m. respectively. (Lactose tolerants) 3) The lactose tolerants had no symptoms induced by lactose load. 4) Most of the maximal increase in breath H₂ concentration (in 8 of 13 lactose intolerants) occured after 4th hour of a 5-hours-collection period. In conclusion, 13(37.5%) of Korean healthy adults could be determined as lactose intolerants by the results of subjective response and the breath H₂ test simultaneously. And breath H₂ test is a practically useful method for screening of lactose intolerance.

For evaluation of diagnostic value and usefulness of the duodenogastric reflux test using Tc-99 m DISIDA in gastric ulcer disease, the scintigraphy was performed in 10 gastric ulcer patients, in 10 duodenal ulcer patients and 15 normal controls at Kyung Hee University Hospital during the period from Nov, 19$4 to SeP 1985. Results are summerized as follow; 1) Duodenogastric reflux was more commonly observed in patients with gastric ulcer than in duodenal ulcer(p$lt;0.25) and normal controls(p$lt;0.01). 2) Total radioactivity of refluxing Tc-99 m DISIDA in patients with gastric ulcer(6.76±3.42%) was higher than that in duodenal ulcer(2.68±2.39%) and normal controls(1.43±0.97%). In conclusion, duodenogastric reflux test using Tc-99m DISIDA can be a useful method to quantify duodenogastric reflux. And duodenogastric reflux may play 'a role in pathogenesis of gastric ulcer disease,
