A microdialysis injector probe administered IL-1alpha into ventromedial hypothalamus (VMN) and concurrently measured release of dopamine (DA), DOPAC, 5-HT, and 5-HIAA. After baseline dialyses, six rats received 2-ng IL-1alpha and six rats received vehicle (1 microl saline) into VMN. Sixty minutes later, food was provided for 40 min while VMN monoamines were(More)
UNLABELLED Based on reports that increased hypothalamic ventromedial nucleus (VMN)-serotonin (5-HT) is associated with cancer anorexia and recent findings in our laboratory that low levels of dopamine (DA) in the VMN are associated with prolonged inter meal intervals thus decreased food intake, and reports that setting up satiation is concomitant with(More)
BACKGROUND Cholesterol is an essential component of cell membranes, precursor of steroids, biliary acids and other components of serious importance in live organism. Cholesterol synthesis is a complicated and energy-demanding process. Real daily need of cholesterol and mechanisms of decline cholesterol levels in critical ill are unknown. During stressful(More)
AIMS We are currently witnessing changes in views on the evaluation of serum proteins. A decrease may signal not only malnutrition. It may also be an indicator of simultaneously occurring inflammatory disease. Prealbumin, due to its short half-life, is a suitable indicator of changes in protein-energy balance, but its levels show, as with other serum(More)
PURPOSE Despite the significant interest in molecular hydrogen as an antioxidant in the last eight years, its quantitative metabolic parameters in vivo are still lacking, as is an appropriate method for determination of hydrogen effectivity in the mammalian organism under various conditions. BASIC PROCEDURES Intraperitoneally-applied deuterium gas was(More)
BACKGROUND Omentin-1 is an anti-inflammatory adipokine produced preferentially by visceral adipose tissue. Plasma levels of omentin-1 are decreased in obesity and other insulin-resistant states. Insulin resistance contributes to the changes of cholesterol synthesis and absorption as well. The aim of this study was to characterise omentin-1 plasma levels in(More)
Obesity in T1DM patients is associated with the components of metabolic syndrome. The influence of controlled fasting and low calorie diet (LCD) on insulin sensitivity and glucose metabolism was studied in 14 obese patients with type 1 diabetes mellitus (T1DM) (42.6+/-9.4 years, BMI 32.4+/-2.1 kg m(-2)). Insulin sensitivity in obese T1DM patients was(More)
