Enteral NaCl absorption in normotensive subjects

Mezlocillin enteral absorption in rabbits.

To determine the role of enterohepatic recirculation on its nonlinear elimination, we studied the enteral absorption of mezlocillin in rabbits. Mezlocillin was not substantially absorbed from the stomach or duodenum. We conclude that enterohepatic recirculation does not cause the dose-dependent elimination kinetics of mezlocillin.

Heterogeneity of cardiorenal characteristics in normotensive subjects.

Blood pressure is a marker of elevated risk for cardiovascular disease, even within the normotensive range. The present study evaluates cardiorenal modifications observed in normotensive (<140/90 mm Hg) subjects. Using World Health Organization-International Society of Hypertension definitions, 265 normotensive subjects were categorized as having optimal (n=73), normal (n=84), and high-normal (...

Autonomic Function in Hypertensive and Normotensive Subjects

Negative pressure respiration, water diuresis and natriuresis in normotensive, hypertensive and prehydrated normotensive subjects.

Sieker, Gauer and Henry (1), examining nor-motensive subjects, have demonstrated that breathing against continuous negative pressure elicits a moderate water diuresis, believed to be mediated by stretch receptors in the left atrium and reflex inhibition of the secretion of the antidiuretic hormone. This water diuresis, which has been confirmed by others (2-4) is not accompanied in nor-motensive...

Cognitive performance in hypertensive and normotensive older subjects.

Longitudinal studies suggest that hypertension in midlife is associated with cognitive impairment in later life. Cross-sectional studies are difficult to interpret because blood pressure can change with onset of dementia and the inclusion of subjects on treatment and with hypertensive end-organ damage can make analysis difficult. We examined cognitive performance in hypertensive and normotensiv...
