OBJECTIVE Diabetes-associated oxidative stress is a consequence of both increased production of free radicals and reduced capacity of antioxidative defense. Prolonged hyperglycemia is the major factor in the pathogenesis of atherosclerosis in diabetes which can lead to cardiovascular complications. The aim of this study was to test the parameters of(More)
INTRODUCTION Oxidative stress and antioxidants play an important role in the pathogenesis of inflammatory disease, including chronic periodontitis (CP). Saliva contains enzymatic (glutathione peroxidase - GPx, superoxide dismutase - SOD, etc.) and non-enzymatic (albumin - ALB, uric acid - UA, glutathione, etc.) antioxidants. OBJECTIVE The aims of this(More)
BACKGROUND Age-related macular degeneration (AMD) is the most common cause of visual impairment in individuals over 50 years of age, with the prevalence of 0.05% before the age of 50 rising to 30% after 74 years of age. An elevated concentration of plasma lipoproteins is considered to be one of the risk factors of AMD development. The aim of our study was(More)
INTRODUCTION Age-related cataract not only diminishes human life quality but it also represents a big impact on healthcare budget of almost every country as the population ages globally. Hence, cataract prevention is a big and true challenge, but a very difficult task to be accomplished. Nowadays cataract is more than a routinely recognized and almost(More)
ZIELSETZUNG: Die Bewertung der Korrelation zwischen Wechselstoffkontrolle und Präsenz und Schweregrad der diabetischen Retinopathie (DR) bei Patienten mit Typ-2-Diabetes. METHODEN: Diese Querschnittstudie umfasste 80 Patienten, die in vier Gruppen eingeordnet wurden, nach der Dauer der Krankheit: de novo; bis zu 10 Jahren; 11 bis 20 Jahre; und über 20(More)
Age-related macular degeneration (AMD) is a complex, degenerative and progressive disease involving the multiple genetic and environmental factors that can result in severe visual loss. The etiology of AMD is not well understood. Many theories exist and feature mechanisms of oxidative stress, atherosclerotic-like changes, genetic predisposition and(More)
BACKGROUND Ischemia-reperfusion-induced acute renal failure (ARF) is associated with a high mortality in patients with hypertension and with an unfavorable outcome of kidney transplants from marginal donors. AIM The influence of allopurinol and enalapril on urinary nitrate/nitrite (UNOx), glomerular filtration rate, plasma and urinary sodium, and(More)
It is well established that a condition of hypercoagulation due to deficiencies of antithrombin III, protein C and protein S may result in thrombo-embolism. To evaluate the possibility of hypercoagulation in acute mesenteric ischemia (AMI); clinical features, ECG changes, drug history, the length of intestine remaining after the resection and mortality of(More)
BACKGROUND The aim of this study was to examine prothrombogenic factors and antioxidative defense in obese children and adolescents with pre-metabolic and metabolic syndrome, and to analyze insulin secretion and resistance, early glycoregulation disorders and lipid status. METHODS Insulin sensitivity was determined using the homeostasis model assessment(More)
BACKGROUND AND AIMS Oxidative stress and inflammation are postulated to be involved in the pathogenesis of the age-related macular degeneration (AMD) although the mechanism linking the oxidation and inflammation is still unknown. The aim of this study was the analysis of the antioxidant capacity measured by levels of the antioxidant enzymes: superoxide(More)
