1 Hypertensive and normotensive rats of the same age group were isolated from an inbred colony of spontaneously hypertensive rats. 2 The perfused hindquarter and mesenteric artery preparations obtained from hypertensive and normotensive rats exhibited an increased reactivity to noradrenaline (NA) and angiotensin II. 3 Dose-response curves to NA obtained from hypertensive and normotensive rats e...

Copyright © 2007 Massachusetts Medical Society. A cute renal failure is defined as a rapid decrease in the glomerular filtration rate, occurring over a period of minutes to days. Because the rate of production of metabolic waste exceeds the rate of renal excretion in this circumstance, serum concentrations of markers of renal function, such as urea and creatinine, rise. The causes of acute rena...

OBJECTIVE Published observations about cardiovascular alterations in normotensive individuals genetically predisposed to develop essential hypertension are conflicting. We tested the hypothesis that abnormalities in left ventricular mass and/or functions may be present in normotensive children of hypertensive parents. METHODS One hundred normotensive offsprings (6 to 18 year age) of hypertens...

1. An investigation was carried out into the mechanism of unexplained hypotension in patients with fulminant hepatic failure. The cardiac output and peripheral resistance were compared in normotensive and hypotensive patients. In addition, the serum concentration of the false neurotransmitter octopamine and the pressor response to noradrenaline, and to the indirectly acting sympathomimetic agen...

The reactivity of vascular smooth muscle in helical strips from femoral arteries of normotensive, spontaneously hypertensive, renal hypertensive, and deoxycorticosterone acetate— (DCA-) hypertensive rats was studied. Spontaneous rhythmic contractions occurred in 25 of the 30 strips from the three groups of hypertensive rats and in only 2 of the 10 strips from normotensive rats. Strips from rena...

Objective-Preeclampsia is one of the leading cause of maternal mortality and morbidity worldwide. The purpose of this study was to determine the level of β hCG and other biochemical markers in preeclampsia and in normotensive patients . Method – This was a prospective study conducted on 50 preeclamptic (case)and 50 normotensive pregnant women (control) in obstetrics and gynaecology department o...

The recent discovery of additional alternative spliced FLT1 transcripts encoding novel soluble (s)FLT1 protein isoforms complicates both the predictive value and functional implications of sFLT1 in preeclampsia. We investigated FLT1 expression levels and splicing patterns in placentas of normotensive and preeclamptic women, and established the tissue specificity of all FLT1 transcript variants....

Studies of normotensive offspring of hypertensive parents offer the potential to identify inherited abnormalities that contribute to essential hypertension. We compared renal and systemic hemodynamic responses to saline infusion between normotensive sons of two hypertensive parents (SOHT) and sons of two normotensive parents (SONT) selected from the general population of Rochester, Minn. Hemody...
