COMPARISON OF SOME OF THE ACTIONS OF ADRENALINE AND NORADRENALINE ON THE KIDNEY
1 Department of Physiology, Edinburgh University
1. Observations were made on conscious dogs of the effect on water excretion during diuresis of both single injections and infusions of adrenaline and noradrenaline. The renal clearances of creatinine and diodone were also measured.
2. Adrenaline, before and after atropinization, decreased the rate of urine flow, the renal plasma flow and the glomerular filtration rate. Before atropine the heart was slowed, but after atropine it was accelerated.
3. Noradrenaline before atropine decreased the rate of urine flow, the renal plasma flow and the pulse rate, but increased the glomerular filtration rate. After atropine the urine flow and pulse rate decreased as before, but both renal plasma flow and glomerular filtration rate increased.
4. It is concluded that neither adrenaline nor noradrenaline has a direct action on kidney activity, but affects it by altering the conditions of the systemic circulation.
