✦ Synopsis

1. A study of the interrelationship between the Bayliss-effect and the vascular tone has been performed on isolated and extracorporeally perfused rabbit kidneys.

2. Variation of the vascular tone of the renal circulatory system was induced by electrical stimulation.

3. During infusion pressure elevation, systems with ]ow vascular tone showed absence of or minor increase in resistance.

4. Systems with intermediate vascular tone responded to infusion pressure elevation with increase in resistance.

5. Absence of autoregulatory response was observed in systems with high vascular tone.

6. The results suggest that the sensitivity to pressure elevation of the renal vascular system in situ is greatly influenced by humeral and neural factors. Autoregulation is the primary haemodynamie regulatory system of the renal vascular bed. But the efficiency of this system is influenced by interrelated neurM and humeral factors.
