Abstract
Our previous studies have suggested that the adrenergic nervous system is involved in the mechanism responsible for the time-dependent change in the urinary excretion of furosemide in rats. To examine a potential role of renal nerves in this phenomenon, renal denervation or sham operation was performed using unilaterally nephrectomized rats. Furosemide (30 mg/kg) was given orally at 12 am or 12 pm. Urine was collected for 8 hours after furosemide dosing, and urinary excretions of furosemide and sodium were determined. Urinary furosemide excretion and diuretic effects of the agent (urine volume and urinary sodium) were significantly greater at 12 am than at 12 pm in the sham-operated group of rats. However these administration time-dependent changes in urinary furosemide and its diuretic effects disappeared in the renal-denervated group of animals. These results suggest that the renal nerves contribute to the time-dependent changes in the urinary excretion of furosemide and its subsequent diuretic effects.
