Abstract
A'hoed calibration method'has been developed for quantitative ebservation andimage analysis of regenerative mucosal pattern of gastric ulcer under a magnifying videeendoscepe. Using this method, we measured the size of regenerative mueosal patternat the margin of ulcers and compared with their healing processes. At the healing stage, palisade-or spindle-shaped regenerative mucosal pattern with a larger area appeared tobe well correlated to the healing of gastric ulcer. When ulcer healing was apparently rapid, the maximum length rather than the area of spindle shaped regenerative mucesal patternwas found to be more closely associated with the healing gastric ulcers. On the other hand, in cobblestone-shaped regenerative mucosal pattern, which corresponds to more matureregenerative tissues, the maximum length and their area were not correlated, with thehealing of gastric ulccr at alb stages. Similarly, at the scaring stags, namcly, at a maturcstage of healing, the sire of regenerative mucosal pattern was considered to he unrelatedwith the healing speed of ulcers or the incidence of ulcer recurrence.
