We examined corticosteroid secretory patterns and their relation to altered salt and water metabolism in Milan hypertensive and normotensive rats. Hypertensive rats had significantly higher blood pressures, exchangeable sodium (hypertensive, 41.2 +/- 0.3 mmol.kg-1; normotensive, 38.4 +/- 0.03 mmol.kg-1, P < .001), plasma volume (hypertensive, 5.39 +/- 0.12 mL.100 g-1; normotensive, 4.84 +/- 0.1...

Background: The cardiac effects simultaneously occurring during experimental hypertension and diabetes have rarely been investigated. This study aimed at examining the effects of short-term renovascular hypertension and type 2 diabetes on cardiac functions. Methods: Five groups (7 each) of male Sprague-Dawley rats, including a control group, a diabetes (induced by Streptozocin and Nicotinamide)...

With increased dietary NaCl intake (8% NaCl), the borderline hypertensive rat develops hypertension, thus expressing the phenotype of the spontaneously hypertensive parent. Since arterial baroreceptor reflex function is impaired in the spontaneously hypertensive parent, it was the objective of this study to examine arterial baroreceptor reflex function in the borderline hypertensive rat made hy...

lisinopril dihydrate (angiotensin converting enzyme inhibitor) is a lysine derivative of enalaprilat and does not require hydrolysis to exert pharmacological activity. it has an extensive hepatic first pass metabolism resulting in a bioavailabil-ity of 6-60%. to overcome the poor bioavailability of the drug, transdermal patches have been prepared. the present study also aims at optimization of ...

BACKGROUND This cross sectional investigation included 12,966 subjects with hypertension, a cohort of the China Stroke Primary Prevention Trial (CSPPT), a randomized, multicenter clinical trial. This study aimed to explore the correlation between serum uric acid (SUA) concentration and hypertensive retinopathy in hypertensive adults. METHODS Diagnosis of hypertensive retinopathy was determine...

BACKGROUND Signs indicating hypertensive retinopathy can help determine the extent of hypertensive cardiovascular, renal and cerebrovascular damage. OBJECTIVES To study the association between hypertensive retinopathy and cardiovascular, renal and cerebrovascular changes, and to determine the predictors of hypertensive retinopathy in Congolese patients. METHODS A total of 159 hypertensive s...

OBJECTIVE To assess the prevalence of hypertensive crisis, related clinical findings, and the organic lesions involved. METHOD This retrospective study comprised the analysis of the medical records of symptomatic patients with an elevation in diastolic blood pressure levels > or = 120 mmHg, who sought the emergency unit of a university-affiliated hospital over 12 months. Hypertensive urgency ...

Background: Numerous studies have shown that serum levels of trace elements including zinc play an essential role in regulation hypertension. Objective: The objective current study is to evaluate the differences among hypertensive and non-hypertensive male participants from Peshawar Khyber Pakhtun Khwa Pakistan. Method: comprised 140 adult males (70 70 non-hypertensive). subject’s age, weight, ...

Epidemiological data on the impact of hypertensive crises (emergencies and urgencies) on referral to the Emergency Departments (EDs) are lacking, in spite of the evidence that they may be life-threatening conditions. We performed a multicenter study to identify all patients aged 18 years and over who were admitted to 10 Italian EDs during 2009 for hypertensive crises (systolic blood pressure ≥2...
