background nasal septal deviation (nsd) can cause upper airway obstruction, which results in hypoxia and therefore, pulmonary vasoconstriction, ventricular hypertrophy and right-sided heart failure. objectives the aim of this study is to determine the mean pulmonary arterial pressure (mpap) of the patients with nsd and the effect of septoplasty on pulmonary arterial pressure. patients and metho...

Introduction: The Bed nucleus stria terminalis (BST) is a part of the limbic system. It was recently shown that chemical stimulation of the BST by L-glutamate elicited cardiovascular depressive responses. In the present study, we have investigated the possible cardiovascular role of the GABAergic receptors in BST by microinjection of its agonist and antagonists. Methods: Experiments were p...
Background: Physical activity has been recognized as one of the non-pharmacological methods in the treatment of hypertensive disorders. This study aims to compare the effects of aerobic exercise performed and alternative (AI) and constant intensities (CI) in hypertensive individuals. Methods: In this semi-experimental study, subjects were 20 hypertensive women who were asked to fill in the q...
Objective(s) Calcium-channel blockers have an important role in the treatment of several cardiovascular disorders. Derivatives of 1, 4-dihydropyridine are one of the most potent calcium antagonists. In this study four novel ', 4-dihydropyridine calcium channel blockers were synthesized and their hypotensive properties were investigated in male rats. Materials and Methods Four 1, 4-dihydropyr...
Background & Aim: Endotracheal suctioning (ETS) is a common invasive nursing procedure. Hemodynamic parameters changes during and after the procedure. If appropriate strategies do not be applied during the ETS, hemodynamic changes can be significant and life threatening in critically ill patients. The purpose of this study was to assess the effect of education of endotracheal suctioning on pati...
conclusions closed suction caused fewer disturbances in patients’ hemodynamic condition, took shorter time, and is more economical. therefore, this method can replace open suction method in caring of severely critically ill patients. results no significant differences were observed between the two suctioning methods in terms of mean systolic blood pressure (p = 0.075), diastolic blood pressure ...
Background and Objective: Laryngoscopy and tracheal intubation can be achieved through both direct and video laryngoscopy. As video laryngoscopy complications still remain unknown among the elderly, this study was emerged to grasp the idea on the complications of two aforementioned methods among the elderly. Materials and Methods: In this clinical trial study, 60 patients over 65 years who h...
conclusions garlic powder consumption can reduce blood pressure, yet in this model, it did not have an effect on the interaction between renin angiotensin system and nitric oxide inhibition. results at the beginning and at the end of experiments, systolic blood pressure was higher in the hypertensive groups than the normotensive group. however, at the end of the study, diastolic blood pressure ...
The role of nucleus tractus solitarius (NTS) in cardiovascular system regulation is controversial. On the other hand, the problem of hypertension in diabetic animals is the subject of many research programs. The aim of present study was to determine whether inactivation of NTS could affect blood pressure and heart rate in diabetic rats. To this end, stereptozotocin induced diabetic rats were an...
