beta-2 adrenoceptors in blood vessels are one of the active factors that play a role in regulation of tissue blood flow. in diabetic angiopathy, responsiveness of these receptors is decreased, while that is increased in inflammation. according to these opposite effects, the aim of this study was to investigate the vasodilatory response of knee joint blood vessels to salbutamol (beta-2 adrenocep...

Measurement of stroke volume by pulsed Doppler echocardiography has not been validated against a reference method in vivo. We compared Doppler systolic frequency shift integrals with electromagnetic flowmeter stroke volume in seven open-chest dogs. A pulsed Doppler echocardiographic transducer was held on the aortic arch with the sample volume in the ascending aorta. Stroke volume was varied by...

The treatment of patient with relapse of bleeding after application of minimally invasive treatment of hemorrhoidal disease such as elastic band ligation, cryosurgical treatment Hemorrhoidal Arterial Ligation (HAL) can be presented as serious clinical problem in patients with concomitant diseases that can be contraindication for radical surgical treatment. We compared the Simple Digital Method ...

abstract introduction: in this study the role of pge2 as an important inflammatory mediator in indomethacine and theophylline effects on joint diameter and vascular response of chronically inflamed rat knee joint to saphenous nerve stimulation was investigated. methods: inflammation was induced by intraarticular injection of 0.2 ml freund,s complete adjuvant (fca) and 3, 7, 14, 21 days post inj...

SUMMARY A range-gated pulsed Doppler flowmeter has recently been developed that measures the average velocity of blood flow within a small tear-drop shaped (4 mm by 2 mm) sample volume. Unlike the continuous wave Doppler, the distance from the transducer face to the sampling site can be continuously varied by a range adjustment knob. Twenty patients with cardiac murmurs were evaluated in a noni...

OBJECTIVE To determine the relative roles of different modalities of sensory nerve function (large and small fiber) and the role of microvascular dysfunction in foot ulceration in type 2 diabetic subjects. RESEARCH DESIGN AND METHODS A total of 20 control subjects and 18 type 2 diabetic subjects with foot ulceration and 20 without were studied. None of the subjects had clinical features of pe...

Cervical Carotid Imaging With a ContinuousWave Doppler Flowmeter • A noninvasive technique for carotid arteriography using an ultrasonic directional Doppler flowmeter to image the carotid bifurcations is described. The technique uses a position sensing arm to hold the sharply focusing probe and translates the position of arterial flow onto an image storage screen. By multiple manual sweeps acro...

In order to investigate how holmium laser enucleation of the prostate (HoLEP) improves urinary storage symptoms, we assessed blood flow in the urinary bladder mucosa of patients with benign prostatic hyperplasia (BPH) before and after laser surgery. Seventy-four consecutive patients with BPH (median age 69 years, range; 53-88) underwent HoLEP at our institution and are included in this study. W...
