Abstract
In order to investigate the changes in plasma renin
activity at various postures in rabbits, the experi
mental animals were maintained at prone, side.
upright, and headside down postures for 10 hours.
Plasma renin activity was measured by the method
of radioimmunoassay.
The data obtained were as follows:
1) At prone posture, the plasma renin activity
was 14.72±3. 49 nanogram per 100ml plasma per
hour. which was regarded as resting plasma renin
activity.
2) At side posture, the plasma renin activity was
46.60±5. 41 ng/100ml plasma/hr, which was signi
ficantly higher than that of resting plasma renin
activity.
3) At upright posture, the plasma renin activity
was 45.82±11. 51 ng/100ml plasma/hr, which was
also significantly higher than that of resting level
4) At headside down posture, the plasma renin
activity was 44. 16±10. 33 ng/1ooml plasma/hr, which Was also significantly higher than that of resting
plasma leve l.
From the adove results. it was concluded that the
postures other than normal prone position in rabbits
stimulated the release of renin in the kidney
