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, tan...

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...

We have investigated the temporal relationship between the hemodynamic and histological/morphological progression in a rat model of pulmonary arterial hypertension that develops pulmonary arterial lesions morphologically indistinguishable from those in human pulmonary arterial hypertension. Adult male rats were injected with Sugen5416 and exposed to hypoxia for 3 wk followed by a return to norm...

Methods Patients with aSAH and occluded aneurysm who developed clinical signs of DCI were randomised to either induced hypertension or no induced hypertension. Hypertension was induced with norepinephrine. Cerebral perfusion was assessed with CTP as CBF (ml/100g/s) in predefined regions (ROIs) on two time points: CTP1) at time of clinical deterioration and CTP2) 24 36 hours after randomisation....

When acute myocardial infarction occurs in patients with hypertension and left ventricular hypertrophy (LVH), the incidence of sudden cardiac death increases markedly. Possible explanations include increased size of the occluded vascular bed secondary to more extensive atherosclerotic coronary vascular disease in the presence of hypertension, decreased coronary reserve secondary to LVH, and int...

Purpose. We report a novel technique which aided recanalization of an occluded portal vein for transjugular intrahepatic portosystemic shunt (TIPS) creation in a patient with symptomatic portal vein thrombosis with cavernous transformation. Some have previously considered cavernous transformation a contraindication to TIPS. Case Presentation. 62-year-old man with chronic pancreatitis, portal ve...

abstract the objectives of this research was to evaluate the rhizospheric effects of wheat (triticum aestivum l.) on the status of various inorganic p fractions and total organic p in 10 calcareous soils amended with 1% (w/w) municipal sewage sludge from the refinery of shahrekord city under rhizobox conditions. thus, wheat plant was planted in completely randomized design with three replicatio...

A 48 year old female with complex cyanotic heart disease and pulmonary hypertension was partly cyanosed because of a persistent left superior vena cava draining into an unroofed coronary sinus. The left superior vena cava, which measured 22 mm in diameter, was successfully occluded with a Günther Tulip Vena Cava Mreye Filter which acted as a barrier for embolisation coils.

Lymph flow is the primary mechanism for returning interstitial fluid to the blood circulation. Currently, the adaptive response of lymphatic vessels to mesenteric venous hypertension is not known. This study sought to determine the functional responses of postnodal mesenteric lymphatic vessels. We surgically occluded bovine mesenteric veins to create mesenteric venous hypertension to elevate me...
