Effectiveness of theophylline prophylaxis of renal impairment after coronary angiography in patients with chronic renal insufficiency.

Contrast media can lead to renal impairment that results in longer hospitalization and increased mortality. Adenosine is a crucial mediator of contrast-induced nephropathy (CIN; an increase in serum creatinine of >or=0.5 mg/dl within 48 hours).

Effect of theophylline on contrast material-nephropathy in patients with chronic renal insufficiency: controlled, randomized, double-blinded study.

Purpose: To investigate whether the adenosine antagonist theophylline reduces the incidence of contrast material-induced nephropathy (serum creatinine level increase of at least 0.5 mg/dL [44.2 micromol/L] in 48 hours) in high-risk patients who have chronic renal insufficiency and have received at least 100 mL of contrast medium.

Chromium uptake by Saccharomyces cerevisiae and isolation of glucose tolerance factor from yeast biomass.

Fermentations with yeast Saccharomyces cerevisiae in semiaerobic and in static conditions with the addition of chromic chloride into the used molasses medium were analysed. It was proved that the addition of optimal amounts of CrCl3 into the basal medium enhanced the kinetics of alcohol fermentations. The addition of 200 mg/l CrCl3 into the medium stimulated both the yeast growth and the ethanol production in all experimental conditions.

[Reduction in left ventricular volume and improvement in hemodynamics following intravenous administration of pimobendan (UDGG 115 BS) in dilated cardiomyopathy].

Acute cardiovascular effects of 5 mg (group I, n = 6) and 10 mg (group II, n = 6) i.v. pimobendan (UDCG 115 BS) were studied by right and left heart catheterizations in patients suffering from idiopathic dilated cardiomyopathy (NYHA II and III).

Effect of intravenous pimobendan (UDCG 115 BS) on hemodynamics and left ventricular volumes in idiopathic dilative cardiomyopathy.

Acute cardiovascular effects of 5 mg (group I, n = 6) and 10 mg (group II, n = 6) intravenous pimobendan (UDCG 115 BS) were studied by right and left heart catheterizations in patients suffering from idiopathic dilative cardiomyopathy (NYHA II and III). Before and 2.5 h after application of pimobendan, left ventricular volumes and left ventricular dP/dtmax were evaluated by left heart catheterization.
