[The glomerular apparatus and renal blood flow in rats during postnatal ontogenesis].
In anesthetized Wistar rats of the age of 4, 12, 30 and 65 days, the renal blood flow (RBF) with laser-Doppler flowmetry, diameter, number and density of glomeruli, diameter of afferent and efferent arterioles were measured. We found that during rat development the RBF increased 2.8-fold, the diameter of glomeruli--3.6-fold, diameter of afferent arterioles--1.8-fold, and the efferent arterioles--rose 1.3-fold. The number of glomeruli increased 1.3-fold, but their density decreased 16-fold.
