The changes in the adipose tissue of the visceroptotic patients were examined and the following results were obtained. 1. The thickness of the subcutaneous adipose tissue of visceroptotic patients is markedly reduced compared with that of the control cases. 2. The diameter of the fat cells of visceroptotic patients is also smaller than that of the control cases. 3. The connective tissue fibers in the adipose tissue are thin and scarce in the interlobular connective tissue and around the fat cells in these patients. From these results is may be concluded that the function of the adipose tissue as a supporting tissue of the abdominal organs in visceroptotic patients is decreased, and it contributes to the ptosis and displacement of the addominal organs. The quantitative reduction of adipose tissue may also induce lowering in the intra-abdominal temperature and affect the pathophysiology of abdominal organs of visceroptotic patients.
