[Possible explanation of the hemoglobin glycation index by the biokinetic model of glycation].

Unlabelled: Összefoglaló. Bevezetés: A HbA1c integrált retrospektív mutatója az elmúlt időszak vércukrának, rendszeres vizsgálata a cukorbetegek anyagcserekontrolljának megítélésében elengedhetetlen. Helyes értékelése azonban nem egyszerű, mert a HbA1c és a vércukor közötti összefüggés nem lineáris.

Improvement of mortality prediction accuracy in critically ill patients through combination of SOFA and APACHE II score with markers of stress haematopoiesis.

Introduction: In critically ill patients nucleated red blood cells (NRBC) and immature granulocytes (IG) appear in the peripheral blood as the consequence of stress haematopoesis. The aim of this retrospective study was to evaluate the diagnostic value of NRBC and IG and to propose a model of improved mortality prediction including these parameters in the assessment of critically ill patients.

Methods: The study included 338 critically ill adult patients hospitalized at Department of Anaesthesiology and Intensive Medicine, Louis Pasteur University Hospital in Kosice.

[Barriers of the initiation of insulin treatment in type 2 diabetic patients - conquering the "psychological insulin resistance"].

Type 2 diabetes is a progressive disease and its consequence is the gradual decrease of endogenous insulin secretion to a very low level. Beyond this point, without insulin it is not possible to achieve proper metabolic compensation. The authors are trying to explain why the insulin therapy is often delayed in type 2 diabetic patients despite existing guidelines about its initiation and continuation.

Toluene abuse markers in marginalized populations.

Toluene abuse is one of the most common addictions among marginalized Roma. The aim of the study was the comparison of urinary toluene metabolite levels in marginalized population of Eastern Slovakia as compared to the majority population, and to verify the validity of the answers, given in the questionnaires, regarding toluene abuse. The study was carried out as part of the HEPA-META project aiming to map the prevalence of health problems in marginalized Roma.

Can imprinting play a role in the response of to toxic substance exposure?

Among protozoa, is the most commonly ciliated model used for laboratory research. All living organisms need to adapt to ever changing adverse conditions in order to survive. This article focuses on the phenomenon that exposure to toxic doses of the toxicants protects against a normally harmful dose of the same stressor.

Changes of procalcitonin level in multiple trauma patients.

Background: Some aspects of the pathophysiology of complications in multiple-trauma patients still remain unclear. Mediators of inflammation have been postulated as playing a key role in being responsible for life threatening complications of multiple trauma patients. The objective of this study was to evaluate the prognostic value of procalcitonin (PCT) level in multiple trauma patients.

Flow cytometric analysis of the basophil cell activating impact of potential drug delivery nanoparticle-candidate.

Introduction: Carbon nanotubes – as artificial nano-size ranged materials –have increasing role in the modern biomedical, diagnostic and therapeutic applications.There is a promising option for their use as more potential drug carriers. Despite the favourable properties, their impact (accumulation, elimination, etc.

Effects of chronic low-dose cadmium exposure on selected biochemical and antioxidant parameters in rats.

The effects of long-term (1 yr) exposure to low doses of cadmium (Cd) dissolved in drinking water on selected biochemical and antioxidant parameters were studied in Wistar rats. Rats were divided into four groups: male control group (C-m), female control group (C-f), male Cd-exposed group (Cd-m), and female Cd-exposed group (Cd-f). Cd groups were exposed to Cd dissolved in drinking water (cadmium dichloride 4.

Professor František Pór, MD--an outstanding internist in the former Czechoslovakia.

Professor František Pór, MD, (1899-1980) graduated at the German Medical Faculty of Charles University (GMF-CHU) in Prague in 1926. In January 26, 1945 he was captured, together with his wife, by the Gestapo and they were deported to the concentration camp to Sered' and later to Terezín (Czechoslovakia) from where they were liberated by the Soviet Army on May 8, 1945. He was a founder and the head of the Internal Clinic of the new Medical Faculty in Košice, from October 1, 1948 until 1971.

Lifetime exposure to low doses of lead in rats: effect on selected parameters of carbohydrate metabolism.

The aim of the study was to assess the effects of exposure to low doses of lead dissolved in drinking water (average daily dose of 2.2 mg kg(-1) day(-1)) on selected carbohydrate metabolism parameters in 20 wistar rats. Animals were divided into two groups - control (C) (group drinking clear water) and experimental group (Pb; group exposed to low doses of lead acetate in a concentration of 100 μmol l(-1) of drinking water).

Red cell antioxidant enzymes and prognostic indexes in patients with burns.

Red cell superoxide dismutase (SOD), glutathione peroxidase (GPX) and catalase (CAT) were measured in 66 burned patients (57 men, 9 women, age 16-78 years). BSAB varied from 15 to 93% and ABSI from 3 to 14 points. In the first week after injury the activity of SOD was significantly decreased as compared with the activity of the enzymes in the control group and was also below the reference values.

Determination of immunological stress and oxygen free radical formation in white blood cells during allergen immunotherapy.

Background: Airway inflammation represents the basis of respiratory allergic disease and is generally associated with increased oxidative stress. As a consequence of successful treatment leading to hyposenzibilization and remission of symptoms, decrease of reactive oxygen formation is expected.

Material/methods: This preliminary study evaluates the production of oxygen free radicals in white blood cells and changes in basic immunological parameters in a cohort of 50 patients (27 females and 23 males, age 14-48 years) with upper airway allergic inflammation caused by pollens, before and during specific immunotherapy.

Age dependency on some physiological and biochemical parameters of male Wistar rats in controlled environment.

The aim of the study was to assess the age dependence on some physiological and serum chemistry parameters of male Wistar rats for the estimation of reference values in controlled environment. We are presenting values obtained from a large number of animals such as survival, average life span, body mass, food and water intake, serum chemistry parameters as total protein, albumin, transferrin and ferritin in serum. One part of this work compares the relationship between rat and human age.

Effect of lifetime low dose exposure to heavy metals on selected serum proteins of Wistar rats during three subsequent generations.

The aim of the study was to assess the effects of exposure to low doses of lead, cadmium and mercury dissolved in drinking water (at a concentration 200-fold of maximum allowable concentration) on selected serum proteins of 120 Wistar rats during three subsequent generations. Animals were divided into four groups in all observed generation-control (C) and three experimental groups exposed to low doses of heavy metals (lead acetate in concentration 100 μM; mercuric chloride in 1 μM; cadmium chloride in 20 μM of drinking water). We studied the biochemical parameters as well as total protein, albumin, transferrin and ferritin in the serum.

Vitamin E-coated dialyzer and antioxidant defense parameters: three-month study.

Atherosclerotic cardiovascular disease is the most frequent cause of death in patients with end-stage renal disease who have undergone dialysis treatment. Oxidative stress, increased lipid peroxidation, and impaired function of antioxidant systems may contribute to the accelerated development of atherosclerosis in chronic renal failure patients during renal replacement therapy. The aim of this study was to investigate the influence of a vitamin E-coated dialyzer on antioxidant defense parameters in hemodialysis (HD) patients.
