An antiserum raised against the synthetic tripeptide pyroglutamyl-histidyl-proline (free acid) was used to localize thyrotropin-releasing hormone (TRH) in the rat central nervous system (CNS) by immunocytochemistry. The distribution of TRH-immunoreactive structures was similar to that reported earlier; i.e., most of the TRH-containing perikarya were located(More)
Oxidative stress and inflammation generate edema in burns. The aim of our study was to assess effect of N-acetylcysteine (NAC) on oxidative stress, inflammation, fluid requirement, multiple organ dysfunction (MOD) score and vasoactive drug requirement. In this study 15 patients were on standard therapy, whereas for other 15 patients NAC was supplemented.(More)
BACKGROUND & OBJECTIVES We evaluated pro- and anti-oxidant disturbances in sepsis and non-sepsis burn patients with systemic inflammatory response syndrome (SIRS). Adhesion molecules and inflammation markers on leukocytes were also analyzed. We hypothesized that oxidative stress and leukocyte activation markers can lead to the severity of sepsis. METHODS(More)
Sepsis and multiple organ failure remain the leading cause of mortality and morbidity in burns. The aim of our study was to analyse the predictive value of extravascular lung water index (EVLWI) in the development of severe septic complications and mortality. The records of 28 patients with total burned surface area >20% were analysed (EVLWI, procalcitonin(More)
LHRH and somatostatin or somatotropin-release inhibiting factor (SRIF) are produced by neurons whose cell bodies are located in telencephalic and diencephalic regions in the rat. Many, but not all, of these neurons project to the external zone of the median eminence (ME), where the peptides are released from the nerve terminals into hypophysial portal(More)
Two to 10 days after complete unilateral surgical isolation of the medial basal hypothalamus (MBH) or 3 months following neonatal monosodium glutamate (MSG) treatment, the presence of growth hormone-releasing hormone (GH-RH) immunoreactive neuronal structures was studied in rats using vibratome sections and GH-RH immunocytochemistry. Neonatal MSG treatment(More)
High-mobility group box protein 1 (HMGB1) is a nuclear protein that may be released actively from monocytes and macrophages or passively from necrotic or damaged cells. Several experimental data suggest that burn injury is accompanied by elevated plasma HMGB, but there are only few data available about its changes in burned patients. The aim of this study(More)
Syringes used to administer intravenous medications in an intensive care unit were cultured, and the isolates were compared with those from positive blood cultures from the same patients. The overall contamination rate was 16%, and syringes used for drugs such as insulin, which support bacterial growth, had higher contamination rates. All syringes should be(More)
The aim of the study was to analyze the oxidative stress response after severe burn injury. We studied the effect of two methods of fluid resuscitation regimes on the oxidative stress reaction. Sixteen patients were involved in the study. Inclusion criteria were the presence of flame burn injury affecting >20% of BSA and in-hospital fluid resuscitation(More)
Hydroxyl radical converts Phe to para-, meta-, and ortho-Tyr (p-Tyr, m-Tyr, o-Tyr), while Phe is converted enzymatically to p-Tyr in the kidney and could serve as substrate for gluconeogenesis. Pathological isoforms m- and o-Tyr are supposed to be involved in development of hormone resistances. Role of Phe and the three Tyr isoforms in influencing insulin(More)
