More than twelve thousand autopsies were performed in Nagasaki district after World War II. From those cases 9,331 were selected, since the patients were born before the time of atomic bomb (AB). They were examined for main histopathological changes, which were classified. Studies were made to elucidate the rise and fall in these changes and determine whether there was a difference in such changes between the group exposed to AB and that non-exposed to AB or not. Statistical examination was also performed in the present investigation to determine whether there were differences among calendar years, age groups, and combinations of age group and calendar year. A significant difference was shown independently in some groups. In the present investigation the autopsy cases dealt with in the whole Nagasaki district were used as controls. Therefore, the results obtained seem to be satisfactory data available for clarification of the actual state and trend in each period of the main lesions of cases of exposure to AB.
