- 9 Downloads
1. No measurable changes in the calibers of the cerebral vessels could be demonstrated when the duodenum, the stomach or the colon of cats or dogs was distended.
2. No measurable changes in the caliber of the retinal vessels of humans could be demonstrated when the stomach or the duodenum was distended.
3. An increase in intracranial pressure on distension of the hollow viscera was observed only when there was a concomitant rise in the venous pressure.
