腎性高血圧症の研究: 遊走腎の腎静脈血レニン活性について

Abstract

Plasma renin activities (PRA) were measured by radioimmunoassay in 13 patients with movable kidney. Blood plasma specimens were obtained from the peripheral vein and both renal veins under supine posture and after upright posture. The results were as follows: 1. There was no difference of PRA in the peripheral vein between the movable kidney and the normal kidney. 2. Renal vein PRA under upright posture was significantly higher than that under supine posture. 3. Renal vein PRA of movable kidneys under upright posture was significantly higher than that under supine posture. Renal vein PRA of the normal kidneys tends to increase under upright posture, but the difference was not significant. 4. The correlation between renal vein PRA and grade of ptosis under upright posture was not significant. 5. The upright/supine ratio of renal vein PRA was significantly elevated in the movable kidney compared with the normal kidney and that ratio was significantly correlative to grade of ptosis.
