摘要：

The frequency response of the blood flow through the rat kidney in vivo was studied. A piston controlled by a random-signal generator compressed the abdominal aorta proximal to the renal artery eliciting stochastical arterial pressure changes of an amplitude of .ltoreq. 5 mm Hg. This small amplitude compared well to physiological conditions. In accord with earlier results from isolated kidneys, pressure induced maxima of flow resistance were found at 0.005 Hz and 0.1 Hz, demonstrating that in vivo humoral and/or nervous factors do not significantly alter the renal vascular response to changes of arterial pressure.
