Renal sympathetic function develops over the first 3 weeks of postnatal life in the rat. In the current study, the effects of neonatal sympathectomy with 6-hydroxydopamine were examined on renal biochemical and functional development. The completeness and persistence of sympathetic nerve loss were confirmed by direct measurement of norepinephrine levels and turnover. Evidence was obtained for adverse effects on cellular maturation, as shown by perturbations in the ornithine decarboxylase/polyamine system, which is controlled partially by beta adrenergic input and which regulates macromolecule synthesis in developing cells. A later phase of 6-hydroxydopamine-induced alterations in renal development was seen during the period in which synaptogenesis is prominent and sympathetic tone is high (end of the 2nd postnatal week to end of the 3rd week): the denervated kidneys displayed supersensitivity of beta adrenergically mediated cyclic AMP responses without changes in receptor binding. The alterations in biochemical indices of cellular maturation were accompanied by abnormalities of renal function. 6-Hydroxydopamine caused an increase in the fractional excretion of sodium and deficits in physiological responsiveness of the kidney to a vasopressin analog. Later on, alterations in glomerular filtration rate and basal urinary osmolality also were prominent. These results indicate that neonatal sympathectomy has an adverse effect on the biochemical and functional development of the kidney.
