...Jennifer M. HUGHES; Stuart J. BUND In the present study, myogenic properties of femoral arteries from control hindlimbs and those distal to external iliac artery partial ligation of spontaneously hypertensive rats (SHRs) and normotensive Wistar–Kyoto (WKY) rats were assessed. Arterial pressure...

..., but is not significantly different in SHR femoral arteries, compared with those from WKY rats. Additionally, wall stress at estimated in vivo pressures under passive and active conditions are similar in SHR and WKY rat arteries. These data demonstrate that increased M/L ratios in resistance arteries from SHRs...

...Tessa SAVAGE; Aisling C. MCMAHON; Adrian MULLEN; Rachel M. TRIBE; Magdi M. YAQOOB Some aspects of vascular reactivity are altered in mild experimental uraemia, as shown by increased myogenic tone and a reduced lumen diameter in the femoral artery. This study was conducted to investigate...

... pressure was recorded, blood samples were taken and the animals killed. Isolated femoral arteries were dissected and mounted on a pressure myograph and myogenic tone was assessed over a range of intravascular pressures from 40 to 160 mmHg. Histologically the arteries were comparatively examined for gross...

...T. J. Smilde; H. Wollersheim; H. Van Langen; A. F. H. Stalenhoef 1. The reproducibility of measurements of the arterial wall thickness in both the carotid and femoral artery was investigated by means of high-resolution B-mode ultrasonography. For this purpose, subjects with normal and increased...

...Lennart Jorfeldt; Hans Rutberg 1. In eight healthy volunteers we compared leg blood flow, as determined in a calf segment by strain-gauge plethysmography, with the flow measured by a constant-rate infusion of Indocyanine Green dye into the femoral artery. The representativeness of the calf segment...

We compared the velocity waveforms in the superficial femoral artery measured by multichannel Doppler ultrasound in 45 subjects: 21 patients with untreated essential hypertension and 24 normal...

...% (mean ± sem, n = 12), whereas those after femoral artery infusions at the same dose were reduced by a mean of only 27·2 ± 4·9%( n = 12). 4. The pattern of extraction seen with noradrenaline infusions administered in a similar manner was the reverse of that with angiotensin II. There was a 28·9 ± 6·8...
