The purpose of this study is to examine quantitatively the relations between the girdle pressures operated on the abdomen and buttock of body according to the increase of time and the displacement or the deformation of thorax, diaphragm, heart and stomark caused. In an erect position, the roentgen photographs of thorax and abdomen were taken on three female subjects (20~21 years old) with eutonic stomach under four different time sequence (0, 3, 6, 9 hours) of the girdle pressure. The displacement and deformation of each viscera were examined by X-ray films thus obtained. The results are as follows: 1. Thorax was not statistically significant according to the increase of time in the girdle pressure. 2. Diaphrame greatly ascended under the increase of time in the girdle pressure after 9 hours, put pressure upon the lung and heart. 3. Heart increased in the height of maximum transverse-diameter, of the left side because of ascending of diaphragm.
