The manner in which norepinephrine, histamine and potassium depend upon calcium ion to
elicit contractile responses in aortic strips has been investigated using mammalian Ringer's …

1. The Mg2+-plus Ca2+-dependent ATPase (Ca2+-ATPase) in human red cell membranes
is susceptible to inhibition by low concentrations of vanadate. 2. Several natural activators of …

HTJDGINS, PATRICIA M. AND WILLIAM W. FLEMING: A relatively nonspecific supersensitivity
in aortic strips resulting from pretreatment with reserpine. J. Pharmac. exp. Ther. 153: 70-…

An 18-week, controlled trial of the influence on blood pressure of a fixed protocol of
manipulative treatment in hypertensive adults was made. Twenty-nine subjects were randomly …

Guy H. Bond* and Patricia M. Hudgins abstract: This paperdescribes the kinetics of inhibition
of Na+-and K+-stimulated adenosine triphosphatase (NaK-ATPase) by Mg24", K+, and …

Dose-effect relationships for iv formaldehyde and acrolein indicate that the cardiovascular
actions of these aldehydes are qualitatively similar to acetaldehyde and propionaldehyde. …

A contaminant present in commercial ATP isolated from equine muscle induces a (Mg 2+ +
K + )-dependent inhibition of human red cell NaK-ATPase (EC 3.6.1.3). This inhibition is …

METHODS Locally supplied New Zealand white rabbits weighing 1.5-2.5 kg were sacrificed
by a blow on the head. The thoracic aorta was removed and aortic strips prepared by the …

Acetaldehyde and propionaldehyde have both been previously shown to possess
sympathomimetic activity and to affect the cardiovascular system. The objectives of the present …

Intestinal muscle was more sensitive than vascular muscle to vanadate. Vanadate caused a
biphasic response in intestinal muscle; inhibition of spontaneous contractile activity was …
