aim and backgruond: blood pressure  , one of the most important public health problem in the world is the main risk factors for heart disease .depression is the common comorbod psychiatric disorder among patient with medicin  conditions .this aim was to    compared   depression between   patients with hypertension and  normal  people . methods and materials: in the case-control ,143 consecative...

To better define the mechanisms of blood pressure control in states of catecholamine excess, we infused norepinephrine for 28 days using subcutaneously implanted osmotic pumps in dogs previously instrumented for monitoring left ventricular dynamics and cardiac output. Plasma norepinephrine rose from 238 +/- 27 to 4346 +/- 952 pg/ml at 21 days, while epinephrine and dopamine levels did not chang...

Although venous capacitance has been studied in the neurally isolated tissue or in the in vitro vein segment, this is the first study of sympathetic regulation of the pressure-diameter relation in mesenteric veins in situ, where innervation is kept intact. In 25 alpha-chloralose-anesthetized rabbits, mesenteric vein diameter (679 +/- 27 microns, ranges of 380-1,050 microns at initial state) and...

Ouabain (80 micrograms/kg) injected into the lateral cerebroventricles (ICV) of rats produced a prompt and sustained increase in arterial blood pressure. A diastolic blood pressure increase of about 40 mm Hg began within 10 minutes of injection and lasted at lest 1 hour. This dose of ouabain had no effect on arterial pressure when given intravenously. The vasopressor response to intracerebroven...

objective: gestational diabetes influences mother’s health and is accompanied by severe complications. relaxation is a complementary method for managing this disease. hence, the current study aimed to evaluate the effect of relaxation on blood sugar and blood pressure changes of women with gestational diabetes. materials and methods: in present randomized control trial, 58 patients with gestati...

conclusions both remifentanil and magnesium had favorable outcomes in preventing hr and map elevation after tracheal extubation. however, remifentanil was associated with more rapid regaining of consciousness and reversal of muscular relaxation. results the hr was significantly lower, immediately after extubation and 3, 5, and 10 minutes after extubation, in both magnesium and remifentanil grou...

It has been shown that cerebral oxygen consumption and blood flow are normal and cerebral vascular resistance is increased in patients with essential hypertension (1). Clinicians have questioned the advisability of lowering arterial pressures in hypertensive patients because of the possible untoward effects consequent to decreased cerebral blood flow (2, 3). We have studied the effect of hypote...

cardiovascular disease has become the main factor of death and birth defects in the world and also in iran. new clinical studies have shown that early diagnosis of patients with coronary artery disease (cad) can contribute to effective prevention or therapeutic structures, which reduce mortality or the next chance of cardiovascular events, and increase the quality of life. most studies on cad d...

TA-993, (-)-cis-3-acetoxy-5-(2-(dimethylamino)ethyl)-2, 3-di-hydro-8-methyl-2-(4-methylphenyl)-1,5-benzothiazepin-4(5H)one maleate, a new 1,5-benzothiazepine derivative with l-cis configuration, has a unique and selective increasing action on limb blood flow with little influence on arterial pressure besides an antiplatelet action. We studied the mechanism of increasing action of TA-993 on limb...

background crocus sativus l. (saffron), which belongs to the iridaceae family, is widely cultivated in iran. cardiovascular effects of saffron has been established in some studies but the effects of chronic administration of saffron (c. sativus) stigma aqueous extract on blood pressure has not been investigated. objectives in this study the effects of saffron (c. sativus) stigma aqueous extract...
