Abstract :
Fluctuations of peripheral blood flux are related to its physiological or pathological conditions. The oscillations in skin and muscle are well studied. Due to the fact that it is hard to install the probe, fewer studies about the oscillation of fluctuations of peripheral blood flux in internal organs have been performed. In this study, using fast laser-Doppler flowmetry (LDF) with a signal fiber probe, we measured the renal cortical flux (RCF) and abdominal aortic blood pressure (AABP) simultaneously in rats. With a continuous wavelet transform, we analyzed the fluctuations of RCF and estimated their values.
