Introduction: Hypertrophied tonsils and adenoids may cause upper airway obstruction and cardio-pulmonary complications due to pulmonary arterial hypertension. The aim of this study was to determine the correlation between mean pulmonary arterial pressure (mPAP) and selected adenotonsilar hypertrophy indexes. Materials and Methods: Thirty two patients with upper-airway obstruction resulting ...

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 ...

background: to study the effect of oral garlic on arterial oxygen pressure in children with hepatopulmonary syndrome. materials and methods: garlic powder in a capsule form was given to 15 children with hepatopulmonary syndrome (confirmed by contrast echocardiography) at the dosage of 1 g/1.73 m2 per day. patients were evaluated clinically and by arterial blood gas every four weeks. results: th...

Magnesium sulfate is widely used in obstetrics and is drug of choice in two important complications of pregnancy, preeclampsia and preterm labor. The antagonistic effects of magnesium sulfate on calcium ion and on platelet aggregation may lead to changes in bleeding time. This study was conducted to evaluate the effect of magnesium sulfate on bleeding time in women with threatened preterm labor...

background: the aim of this study was to evaluate the effect of two injections doses of magnesium sulfate for controlling and reducing hemodynamic changes caused by laryngoscopy and endotracheal intubation in pregnant women who were candidates for caesarean section with general anesthesia. methods: in this controlled randomized double-blind clinical trial, 165 pregnant women who were candidates...

background: the obesity and hypertension are the major risk factors of several life threatening diseases. the present study was aimed to investigate the relation between body mass index (bmi) the validated index of adiposity and different aspect of blood pressure (bp). methods: systolic and diastolic blood pressures and also weight and height of 7 to 18 years old children and adolescent col­lec...

Curves relating renal sympathetic nerve activity and mean arterial pressure were derived in conscious rabbits during ramp changes in mean arterial pressure, elicited by perivascular balloon inflation. The renal sympathetic nerve activity-mean arterial pressure relationship consisted of a high-gain sigmoidal region about resting, where renal sympathetic nerve activity rose or fell in response to...
