renal perfusion with tyrode solution to which gelatinol was added revealed gradual development of structural changes in renal vessels as arterial hypertension was developing and stabilizing in spontaneously hypertensive rats , as evidenced by shifts in `` '' perfusion pressure -- perfusion rate '' '' and `` '' glomerular filtration rate -- perfusion pressure '' '' curves , increased afferent/efferent arteriole resistance ratio and enhanced renal vascular response to angiotensin ii due to hypertrophy and reduced inner radius of smooth-muscle afferent arterioles .
