M. Gerova et al., NITRIC-OXIDE IN THE PERIENDOTHELIAL AREA OF FEMORAL VEIN OF THE DOG ASSESSED IN-VIVO BY A PORPHYRINIC SENSOR, Physiological Research, 45(4), 1996, pp. 285-289
Nitric oxide concentration in the periendothelial area of the femoral
vein in anaesthetized dogs was measured directly with a catheter- prot
ected porphyrinic sensor. A 2- to 4-fold increase occurred in the basa
l NO concentration of 90+/-12 nM after acetylcholine injection (1-1.5
mu g/kg). A linear correlation was found between femoral artery blood
flow and NO concentration in the periendothelial area of the femoral v
ein. Noradrenaline decreased NO levels below the detection limit of th
e porphyrinic sensor (10 nM).
