PURPOSE To test the hypothesis that human choroidal blood flow (ChBF) may depend, not only on ocular perfusion pressure (OPP), but also on absolute mean arterial pressure (MAP) and intraocular pressure (IOP). METHODS There were two study days in an open design. On the first day, OPP was varied by elevating IOP during a squatting-induced increase in MAP (28 subjects). On the second day, only t...
Serial data were analyzed for blood pressure recorded between the ages of 9 to 18 years for 278 children and for a subset of this group whose blood pressure was measured at the age of 30 +/- 5.0 years (n = 93). Blood pressures were measured by auscultation over the antecubital fossa with the participant seated. Systolic blood pressure was recorded when the first sound was heard, and diastolic b...
Background: A pressure ulcer is a complication related to the need for the care and treatment of primarily disabled and elderly people. With the decrease of the blood flow caused by the pressure loaded, ulcers are formed and the tissue will be wasted with the passage of time.Objective the aim of this study was to construct blood flow monitoring system on the heel tissue which was under external...
Background: Exercise improves functional capacity by improving endothelial function and musculoskeletal aerobic metabolism, but its effects on hemodynamic control are not well known. The aim of this study was to investigate the effect of aerobic and resistance trainings on structural changes and blood pressure in patients with heart failure. Materials and methods: 76 patients aged 65 to 79 year...
BACKGROUND Frequent and large cardiovascular and neuroendocrine responses to psychological stress are thought to enhance an individual's risk for cardiovascular diseases. Preliminary data suggest that levels of reproductive hormones affect the magnitude of stress responses, perhaps contributing to the protective effect of ovarian hormones on premenopausal women's rates of coronary heart disease...
Blood pressure (BP) response to renal denervation (RDN) is highly variable and its effectiveness debated. A procedural end point for RDN may improve consistency of response. The objective of the current analysis was to look for the association between renal nerve stimulation (RNS)-induced BP increase before and after RDN and changes in ambulatory BP monitoring (ABPM) after RDN. Fourteen patient...
The objectives of this study were to Investigate the changes in blood pressure ( systolic and diastolic) , serum lipids , glucose, electrolytes, blood cell count and weight during Ramadan fasting in apparently healthy muslem men. Eighty male college students or staffs were followed in 3 stages during the month of Ramadan. Blood pressure, weight and height were measured on day one ( baseline) ,a...
The effect of clonidine, a central alpha2-adrenoreceptor agonist on reduction of anxiety, producing sedation and attenuation hemodynamic changes, were assessed during thissemi-experimental study in one of the hospitals of Iran medical sciences university in Tehran, 1994. Fifty surgical patients of either sex, 18-60 years of age, with ASA physical status I or II, gave informed consent to ent...
Background: Royal Jelly (RJ) is a mixture of protein, glucose, lipid, vitamins, and minerals that is widely used as a commercial medical product. Previous studies have shown that RJ has physiological effects such as anti-inflammatory, anti-tumor, anti-allergic, and antioxidant. In the present study, the effects of RJ on some cardiovascular disease risk factors were investigated in patients with...
