title: Dibucaine number (DN) in duodenal ulcer.
abstract: Dibucaine Number (DN) was determined in 103 patients suffering from duodenal ulcer diagnosed radiologically and 214 normal subjects (control). Statistically significant (p less than 0.001) difference was observed in the distribution of DN in the two groups. Whereas 94% of the control subjects had normal DN (above 70), 6% had intermediate DN (between 40--70) and none had atypical DN, only 32% of patients suffering from duodenal ulcer had normal DN, 64% had intermediate DN and 4% had atypical DN. The results have been discussed.
