AIMS Contrast-induced nephropathy (CIN) is a frequent complication of many radiological procedures involving the application of contrast media. It represents a significant health problem that causes the increase in mortality, morbidity, and medical costs. For the prevention of CIN, a number of methods have been proposed to be effective. Among them,(More)
By using red wine, dealcoholized red wine, polyphenols-stripped red wine, ethanol-water solution and water, the role of wine polyphenols and induction of plasma urate elevation on plasma antioxidant capacity was examined in humans (n=9 per beverage). Healthy males randomly consumed each beverage in a cross-over design. Plasma antioxidant capacity (measured(More)
By using red wine (RW), dealcoholized red wine (DARW), polyphenols-stripped red wine (PSRW), ethanol-water solution (ET), and water (W), the role of wine polyphenols, ethanol, and urate on vascular function was examined in humans (n = 9 per beverage) and on isolated rat aortic rings (n = 9). Healthy males randomly consumed each beverage in a cross-over(More)
We examined and compared mechanisms of the red wine (RW)-induced vasorelaxation in guinea pig (GP) and rat aorta. Acetylcholine-induced relaxation of norepinephrine-precontracted aortic rings was stronger in rat aorta than in GP aorta, whereas RW-induced vasorelaxation was stronger in GP aorta. L-nitro-arginine methyl ester (L-NAME) abolished RW-induced(More)
In contrast to the strawberry fruits, strawberry leaves as a source of bioactive compounds with potentially beneficial biological effects have been largely overlooked. In this study we examined direct, dose-dependent effects of wild strawberry (Fragaria vesca, L.) leaves aqueous extract, in two experimental models and animal species, the isolated guinea pig(More)
A case of a 45-day-old male infant, bitten on the neck by nose-horned viper (Vipera ammodytes ammodytes), is reported. This episode occurred while the baby was on a picnic with his parents in a hill near a town in southern Croatia. In spite of immediate arrival at hospital, where antivenom was administrated and all the necessary treatment measures were(More)
Common reference values of arterial stiffness indices could be effective screening tool in detecting vascular phenotypes at risk. However, populations of the same ethnicity may differ in vascular phenotype due to different environmental pressure. We examined applicability of normative equations for central augmentation index (cAIx) derived from Danish(More)
Direct, dose dependent effects of the nose-horned vipers (Vipera ammodytes ammodytes) venom on various parameters of cardiac action in isolated rat hearts were examined. Biochemical (protein content, SDS polyacrylamide gel electrophoresis) and biological (minimum haemorrhagic and necrotizing dose and lethal dose (LD(50))) characterization of the venom was(More)
A 40-year-old man was hospitalized in the coronary care unit with chest pain and abnormal electrocardiogram. Twenty days earlier, the patient underwent laparoscopic gallbladder surgery. Due to chest pain and ischemic ECG changes, patient was subjected to coronary angiography. The selective coronary angiography revealed multiple multilateral fistulae arising(More)
The effects of hyperbaric oxygenation (HBO₂) on acetylcholine-induced vasorelaxation (AChIR) were evaluated in male Sprague-Dawley (SD) rats randomized into four groups: healthy controls (Ctrl), diabetic rats (DM), and control and diabetic rats that underwent hyperbaric oxygenation (Ctrl+HBO₂ and DM+HBO₂). AChIR was measured in aortic rings, with L-NAME,(More)
