第I編 腎・腎反射現象

抄録

There is some accounts of experimental study of reno-renal reflex in animal, but no systematic study in human body. I inserted the ureteral catheter to the renal pelvis of several hundreds normal and tuberculous kidney. And different stimulations (sulfuric acid, caustic soda, alcohol, silver nitrate, sodium iodide, positive pressure, negative pressure, warm water and cold water) were added to one kidney (1) and to one ureter (2) by means of inserted ureteral catheter, and to urine bladder (3) using cystoscop.
I. Reno-Renal Reflex.
(1) When I examined 395 noamal cases, 18% had oliguria, 1.5% had polyuria, most of them began to show the phenamenon within 0.5 minute just after the stimulation, reached the maximum within 1 minute, immediately began recovering within 5 minutes. The phenomenon was observed in the highest percentage and in the highest degree with sulfuric acid and caustic soda, in a lower percentage and in a slighter degree with positive preasure and in the lowest percentage and in the slightest degree with negative pressure and sodium iodide.
(2) The effect of the normal kidney stimulation towards opposite tuberculous kidney (146 cases): In the initial tuberculous kidney, the oliguria was found in higher percentage (36%) and in higher degree than in case of (1), and it began immediately after stimulation. The polyuria also showed the same tendency. But in the heavier tuberculous kidney the oliguria occured in lower percentage (7.4%), in lower degree and in shorter minute than in case of (1), and we could not find the polyuria.
(3) The effect of tuberculous kidney stimulation towards the opposite normal kidney (166 cases): In the initial tuberculos kidney, the oliguria was found in higher percentage (25%), in lower degree and in shorter minute than in case of (1), while it occured in the heavier tuberculous kidney in lower percentage (10.9%), in slighter degree and in shorter minute than in case of (1). We could not find the polyuria all through the stadium of disease.
