background: hawthorn species decreases blood pressure and relaxes precontracted vessels. this study aimed at examining the antihypertensive effect and related mechanisms of hydroalcoholic extract of crataegus azarolus subspecies aronia fruit in rats with renovascular hypertension. methods: six groups of male sprague-dawley rats, each containing 6 to 8 rats, were studied. the groups comprised of...

     Colocasia esculenta Linn (CE) is traditionally used for the treatment of various ailments such as high blood pressure, rheumatic pain, pulmonary congestion, etc. Hence in present study, the effect of aqueous extract of CE leaves (AECE) was evaluated for antihypertensive and acute diuretic activity in rats. Preliminary phytochemical evaluation revealed the presence of carbohydrate, saponins...

background: nitric oxide synthase (nos) activity is increased during hypertension and cerebral ischemia. nos inactivation reduces stroke-induced cerebral injuries, but little is known about its role in blood-brain barrier (bbb) disruption and cerebral edema formation during stroke in acute hypertension. here, we investigated the role of nos inhibition in progression of edema formation and bbb d...

discussion splenic artery aneurysm is a very uncommon cause of page kidney and to our knowledge, it was the first case of its kind ever reported in the literature. introduction the page kidney is a rare phenomenon that refers to hypertension resulting from any external compression of a kidney by a hematoma, tumor, lymphocele, or urinoma. the activation of the renin-angiotensin-aldosterone syste...

CONSTRICTION of one renal artery in the dog does not as a rule produce sustained hypertension. Removal of the contralateral kidney, or bilateral renal artery constriction is necessary for the production of permanent hypertension. On the other hand, sustained hypertension may be produced regularly in the rat by unilateral renal artery constriction. Tt has been postulated that, in the rat, long s...

BACKGROUND Renovascular hypertension is defined as hypertension caused by renal artery stenosis. The two main etiologies are atherosclerosis and fibromuscular dysplasia. Fibromuscular dysplasia in an accessory renal artery as a cause of renovascular hypertension is uncommon. CASE PRESENTATION In this report, we present a relatively uncommon case of renovascular hypertension in a 35-year-old f...

Hypertension remains the most common reason for patients to visit physicians in the United States. Although awareness of hypertension among patients continues to increase, adequate control of hypertension remains poor. In addition, as the population of patients with hypertension ages, atherosclerosis becomes increasingly prevalent. Atherosclerotic renal artery stenosis is the most common second...

Renal artery stenosis is a common cause of secondary hypertension with a rising incidence due to systemic atherosclerosis in an aging population. Patients with renovascular disease complicated by refractory hypertension, acute pulmonary edema, or progressive renal dysfunction benefit from aggressive medical therapy and may be considered for renal revascularization. Atherosclerotic renal artery ...

background: numerical study of angulation effects of renal arteries on blood flow has been of great interest for many researchers. objective: this paper aims at numerically determining the angulation effects of stenosed renal arteries on blood flow velocity and renal mass flow. method: an anatomically realistic model of abdominal aorta and renal arteries is reconstructed from ct-scan images and...
