Two paramagnetic chelates, chromium EDTA and gadolinium DTPA, were evaluated as
potential intravenous contrast agents for magnetic resonance imaging (MR) using a 0.5-T …

To provide contrast enhancement in magnetic resonance imaging, a new class of compounds
has been developed, the paramagnetic metal ion chelates. Gadolinium (Gd) DTPA, a …

An alpha-streptococcus brain abscess was produced in five dogs and studied with magnetic
resonance (MR) imaging (0.5 T) and computed tomography (CT). Non-contrast- and contrast…

The primary objective of this study was to test the hypothesis that endogenous adenosine/A1
receptor interactions participate in the normal regulation of the cardiovascular system and …

1. Increased G i ‐protein‐mediated receptor–effector coupling in the vasculature of the
spontaneously hypertensive rat (SHR) has been proposed as a contributing factor in the …

The purpose of this study was to test the hypothesis that circulating red blood cells (RBCs)
release adenosine deaminase (ADA) when injured. This hypothesis was evaluated in rats …

Adenosine A 1 receptor antagonists are being developed for use as diuretics in the treatment
of hypertension, however, there is relatively little data in hypertensive animal models …

We recently found that the type IV-specific phosphodiesterase inhibitor Ro 20-1724 increases
isoproterenol-induced cAMP secretion in the isolated rat kidney, whereas type I- and type …

The purpose of this study was to compare the effects of prostaglandin I2 on several
cardiovascular parameters and to compare the ability of prostaglandin I2 to modify angiotensin II-…

… Herzer … Herzer … Moreover, the actual experiments were conducted by a different
operator (WA Herzer in the present study vs. Dr. Ping Li in our previous study). …
