Abstract
Some NK cell subpopulations may be involved in the modulation of fibrogenesis in the liver. The aim of the study was to evaluate the relationship between the number and phenotype of NK cell subsets in peripheral blood (PB) and total NK cell percentage, population density and the degree of liver fibrosis of patients infected with hepatitis C virus (HCV+). The study group consisted of 56 HCV+ patients, divided into two subgroups: patients with mild or moderate fibrosis and patients with advanced liver fibrosis or cirrhosis (F ≥ 3 in METAVIR classification). The preparations were stained with H-E and AZAN staining. NK cells were targeted with anti-CD56 antibody and identified automatically in situ using the DakoVision system. Assessment of different NK cell subsets in PB was performed with the flow cytometry technique. In the PB of HCV+ patients with advanced liver fibrosis, there was a lower proportion of CD62L+; CD62L+/CD94++; CD27+; CD127+/CD27+ and CXCR3+/CD27+ NK subsets, as compared to patients with mild/moderate liver fibrosis. The results also showed no association between total PB NK cell level and total intrahepatic NK cell population density between patients with mild/moderate fibrosis and with advanced liver fibrosis. However, positive correlations between the PB levels of CD94+ and CD62L+ NK cell subsets and the intrahepatic total NK cell percentage and population density in the liver, irrespectively to the extent of fibrosis, were observed. Additionally, positive correlation was found between the PB CXCR3+/CD94+ NK cell percentages and intrahepatic NK cell percentages in patients with advanced hepatic fibrosis. Lower blood availability of specific NK subsets in patients with chronic type C hepatitis might be a cause of progression of liver fibrosis via insufficient control over hepatic stellate cells.

Abstract
BACKGROUND The aim of this study was to assess the nutritional status and serum concentrations of adipokines in children with irritable bowel syndrome (IBS) and healthy controls. We also sought to evaluate their relation to metabolic parameters. METHODS We studied 33 IBS patients (11 girls, 22 boys) aged 5-17 years and 30 healthy age-matched controls (11 girls, 19 boys). The analysis included anthropometric measurements, body composition parameter measurements using bioimpedance, and biochemical tests and measurements of serum concentrations of leptin, adiponectin, chemerin, and omentin-1. RESULTS The results of the anthropometric measurements were comparable between the patients and the controls. The patients had higher triglycerides, HOMA-IRs, and chemerin concentrations than the healthy subjects. The HDL cholesterol and omentin-1 levels were lower than in the controls. Leptin and adiponectin did not differ significantly between the groups. An analysis of the receiver operator curves (ROCs) showed that serum concentrations of chemerin ≥ 232.8 ng/mL had 30% sensitivity and 87% specificity when they were used to differentiate between children with IBS and healthy subjects. In the case of serum omentin-1 concentrations ≤ 279.4 ng/mL, the sensitivity and specificity were 60% and 80%, respectively. CONCLUSIONS The nutritional status of children with IBS did not differ from that of the healthy controls. We found significant differences in serum chemerin and omentin-1 concentrations between IBS patients and healthy children. These adipokines could be used as IBS biomarkers as they demonstrate good specificity and moderate sensitivity. The serum concentrations of chemerin and omentin-1 in IBS patients were related to nutritional status and insulin resistance.

Abstract
OBJECTIVES To assess pancreatic exocrine function in patients with anorexia nervosa using a breath test with 13C-labeled mixed triglycerides (MTG-BT) and to determine the relationship between the test results and selected biochemical and hormonal parameters. MATERIAL AND METHODS Anthropometric measurements, biochemical and hormonal parameters (serum leptin, soluble leptin receptor (sLR), acylated and desacylated ghrelin, free leptin index (FLI)), and MTG-BT were performed in a group of 31 girls with the restrictive type of AN, as well as 38 healthy girls (C). RESULTS The average cumulative dose of 13C-triglycerides recovered with exhaled air (%CD) was similar in both study groups, while the average time from 13C-triglycerides administration to peak 13CO2 excretion in expired air (time to peak (TTP)) was significantly longer in patients with AN compared to C. In both groups, %CD correlated negatively with FLI. TTP correlated negatively with sLR and FLI in the AN and with serum insulin and HOMA-IR values in the C. CONCLUSIONS In girls with AN, the pancreatic efficiency of lipase secretion was found to be normal, while the kinetics of this enzyme secretion were disturbed. These changes may result from disorders in the functioning of the adipose-insular and islet-acinar axes.

Abstract
OBJECTIVES The aim of the study was to compare Insulin-like Growth Factor-1 (IGF-1)concentration in pregnancies complicated by pregnancy-induced hypertension and/or intrauterine hypotrophy, and its correlation with maternal pressure and umbilical artery pulsatility and resistance indices. MATERIAL AND METHODS 65 pairs pregnant-newborn were included to four groups: I - control, II - PIH, III - Hypotrophy, IV - PIH and Hypotrophy. In the study we analyzed cord blood IGF-1 concentration, newborns antropometry, umbilical artery pulsatility and resistance indices and maternal pressure before delivery. RESULTS The concentration of IGF-1 was the lowest in IV group of hypotrophic newborns from pregnancies complicated by pregnancy-induced hypertension. In this group of patients there was strong negative correlation between IGF-1 concentration and maternal systolic and diastolic pressure. CONCLUSIONS There is a strong negative correlation between IGF-1 concentration and maternal systolic pressure in group of hypotrophic newborns from pregnancies complicated by pregnancy-induced hypertension.

Abstract
BACKGROUND Immune cell dysfunction is listed among complications resulting from chronic kidney disease (CKD). It could be associated with T-cells, which play a role in the lymphocytic migration and infiltration. However, the data on chemokine receptors expression on T-cells in patients with CKD particularly treated with peritoneal dialysis (PD) are still limited. METHODS The study aimed at multiparameter flow-cytometric analysis of the absolute numbers and percentage of T-cell subsets with surface chemokine receptors (CCR4, CCR5, CCR7, CXCR3, and CXCR4) or receptors' combinations in 47 children treated with PD. RESULTS We found lower absolute numbers of total T lymphocytes, lymphocytes with surface CCR5, CXCR4+CCR5, CXCR3+CCR5 antigens and T-cells with CCR4, CCR4+CD4, CXCR3, CXCR3+CD4, and CD8 receptors. Lymphocytes T with CD4, CCR7, CD28+CCR7, CXCR3+CD8 antigens showed higher percentage in children on PD as compared to healthy children and opposite percentage values of CCR4+, CCR4+CD4+, CXCR3+ T lymphocytes were diminished. Mean fluorescent intensity for CCR7+, CCR7+CD45RO+, CCR7+CD28+, CXCR4+CD4+, CCR5+CD4+, CCR4+, CCR4+CD4+ T-cells was lower in the PD group than in healthy children. The analysis of correlation between T lymphocyte subpopulations with chemokine receptors and other parameters revealed positive correlation of CCR7+ and CCR7+CD28+ T-cells and weekly creatinine clearance, negative correlation between the percentage of CD45RO+CCR7 antigen positive T-cells and KT/Vurea. SUMMARY In conclusion, we could not confirm the phenomenon of earlier senescence of T-cells in children with CKD on PD treatment. This still requires further investigation. The higher percentage of T-cells with CCR7 surface receptor could be responsible for the increase of proliferation activity in this group of children.

Abstract
Objectives Malnutrition and loss of appetite represent a serious problem in children with chronic renal failure. Ghrelin is a newly described hormone involved in control of growth hormone secretion, stimulation of food intake, and regulation of energy balance. Methods Plasma ghrelin levels were compared between 12 children on automated peritoneal dialysis (APD) and 9 children on conservative treatment of chronic renal failure. Eight healthy children matched for age and body mass index (BMI) served as a control group. Results Plasma ghrelin levels were similar in children on APD (698.3 ± 59.7 pg/mL) and children on conservative treatment (675.4 ± 41.9 pg/mL) compared to healthy controls (700.1 ± 24.7 pg/mL). There was no difference in plasma ghrelin levels in children with chronic renal failure regardless of the method of treatment (peritoneal dialysis vs conservative treatment). The plasma ghrelin index was similar in all three investigated groups: APD 40.2 ± 8.7 vs conservative treatment 39.1 ± 5.6 vs controls 41.0 ± 7.8 (pg/mL)/BMI (kg/m2). Plasma ghrelin levels did not correlate with age, duration of dialysis treatment, height, weight, BMI, creatinine and urea levels, adequacy parameters, or nightly glucose load. Conclusion Plasma ghrelin levels in children on APD were not different from levels in children on conservative treatment or healthy controls with comparable BMI. The persistent state of toxic influence of uremic end-products could be responsible for such a lack of correlation with anthropometrical parameters. Further studies on a larger group of children on APD are needed to clarify the effect of ghrelin on nutritional status in children with chronic renal failure.

Abstract
An increasing number of patients with parotid gland tumors have been observed in recent years. The relationship between the immune system and tumor formation is thoroughly investigated. However, newly discovered molecules offer a new insight into the pathophysiology of malignancies. It would be ideal to find an easily determinable biomarker of tumor existence, its malignant potential or a biomarker suggesting the probability of disease recurrence. Our study is the first to examine serum concentrations of IL-33 and its sST2 receptor in patients with various types of parotid gland tumors. Serum IL33, sST2, IL-4 and IL-10 concentrations were determined in patients with benign and malignant parotid gland tumors (pleomorphic adenoma, Warthin's tumor, myoepithelioma and acinic cell carcinoma). We observed for the first time that serum IL-33 level was significantly elevated in patients with various types of parotid gland tumors and sST2 levels were significantly higher in pleomorphic adenoma and acinic cell carcinoma patients compared to the controls. Our results demonstrate for the first time that serum IL-33 and its sST2 receptor may be important factors in the pathology of parotid gland tumors. Although our results are promising, further investigations are required to detect if serum concentrations of those molecules may be a biomarker in parotid gland tumors. Impact statement Parotid gland tumors seem to be an increasingly important medical challenge, mostly due to a noticeable increase in the incidence. It would be crucial to find an easily determinable biomarker of tumor existence, its recurrence or malignant potential. We observed for the first time that serum IL-33 level was significantly elevated in patients with various types of parotid gland tumors and its sST2 receptor levels were significantly higher in pleomorphic adenoma and acinic cell carcinoma patients compared to the controls. We believe that our study helps to understand the biology of the tumors and a potential role of a relatively newly identified cytokine IL-33 in the pathophysiology of the parotid gland tumors.

Abstract
Introduction Chronic kidney disease (CKD) is one of risk factors for stroke and may be associated with impaired platelet reactivity. Objectives The aim of the study was to evaluate platelet reactivity in patients with CKD treated with acetylsalicylic acid (ASA), using 2 different laboratory methods. Moreover, we searched for factors responsible for the phenomenon of high on-treatment platelet reactivity (HOPR). Patients and methods A total of 108 patients with CKD and 41 controls without CKD using ASA were enrolled in the study. Platelet function was assessed by impedance aggregometry in whole blood, using a multi-channel platelet function analyzer (Multiplate®; ASPItest). Urinary 11-dehydrotromboxane levels were measured by the AspirinWorks® test. Results No significant differences were observed in the prevalence of HOPR between patients with and without CKD. Patients with CKD and HOPR measured by ASPItest had higher creatinine levels (P = 0.05) and were younger (P <0.01) than patients with CKD without HOPR, while patients with CKD and HOPR measured by AspirinWorks® had lower red blood cell count (P = 0.05), hemoglobin (P = 0.05), hematocrit (P = 0.05), and high-density lipoprotein levels (P = 0.05). All patients with HOPR had higher C-reactive protein levels (P <0.05) (AspirinWorks®) and white blood cells (P <0.05) (ASPItest). Conclusions The applied methods allowed to detect HOPR in more than one third of CKD patients taking ASA for stroke prevention. The compatibility of both methods for HOPR assessment was confirmed. The study revealed several potential risk factors for HOPR in CKD, including younger age, higher levels of inflammatory markers, dyslipidemia, and lower hematocrit and hemoglobin levels.

Abstract
BACKGROUND The current public health problem is the increasing bacterial resistance to antibiotics. Microorganisms isolated from infections are more often non-susceptible to most available drugs. The microorganisms producing resistance mechanisms have been classified as so called alert pathogens. METHODS We performed a total number of 3810 tests of bronchoalveolar lavage and sputum of patients hospitalized for respiratory diseases at the Department of Pulmonary Diseases and Tuberculosis at Public Clinical Hospital No 3 in Zabrze (Poland). The research was performed in the microbiological laboratory of the Department of Microbiology and Immunology in Zabrze, Medical University of Silesia in Katowice, Poland. The analysis included Gram-positive and Gram-negative alert species strains. RESULTS In the period of five years, 144 strains of alert microorganisms have been isolated. The percentage of Gramnegative alert pathogens producing ESBL and KPC increased. MRSA, Steptococcus pneumoniae and Streptococcus pyogenes have been found to be the most often present among Gram-positive alert microorganisms. The lowest value of cultured alert pathogens (3.9%) was noted in 2008, whereas the highest (16.5%) in 2011. Gram-positive alert microorganisms showed resistance to macrolides and lincosamides, however, Gram-negative alert microorganisms showed the highest percentage of resistance to penicillins, penicillins with inhibitors and cephalosporins. CONCLUSIONS Our work has shown that over the period 2008–2012 an increased percentage of Gramnegative and Gram-positive alert microorganisms was observed.

Abstract
Objective Myasthenia gravis (MG) is a disease with autoimmune etiology. The main pathomechanism is related to the production of antibodies against nicotinic acetylcholine receptor. The present study is aimed to compare the serum level of adipokines in patients with MG with that in controls, as well as to study the relation of these levels with disease severity. Patients and methods Fifty patients with MG and 30 healthy individuals were enrolled in our study. Serum concentrations of select adipokines, namely adiponectin, leptin, omentin, visfatin, and resistin were measured. Results The results showed a significant increase in serum concentrations of adiponectin and resistin in the patients with MG compared with the controls. Conclusion Further studies are warranted to assess changes in adipokine concentration levels in patients with MG.

Abstract
OBJECTIVE We aimed to assess the prevalence of autoantibodies against the 4A subunit of the gastric proton pump (ATP4A) in pediatric type 1 diabetes (T1D) patients and explore the relationship between ATP4A positivity and blood cell count, iron turnover, and vitamin B12 concentration. SUBJECTS The study included 94 (59% female) T1D children (aged 12.5 ± 4.1 years, T1D duration 4.2 ± 3.6 years, HbA1c 7.3 ± 1.5% (57 ± 12.6 mmol/mol) with no other autoimmune diseases. METHODS ATP4A antibodies were measured in T1D patients using a radioimmunoprecipitation assay. Blood cell count, iron concentration, total iron binding capacity, ferritin, transferrin, hepcidin, and vitamin B12 concentration were measured in all the study participants. RESULTS A total of 16 (17%) children were ATP4A positive. Serum concentrations of ferritin were significantly lower in ATP4A positive than in antibody negative subjects (P = .034). Overall the levels of ATP4A antibodies (ATP4A Index) correlated positively with the age at T1D diagnosis (r = 0.228, P = .026) and negatively with ferritin levels (r = -0.215, P = .037). In ATP4A positive patients, the ATP4A Index correlated positively with age at diagnosis (r = 0.544, P = .032) and negatively with vitamin B12 levels (r = -0.685, P = .004). CONCLUSIONS ATP4A antibodies were present in a significant proportion of children with T1D. Higher ATP4A levels in T1D children are associated with lower, yet still fitting within the normal range, levels of vitamin B12, and ferritin. Routine screening of T1D children for gastric autoimmunity (ATP4A) should be considered with follow-up of those positive for vitamin B12 and iron deficiency.

Abstract
AIM The aim of the study was to assess markers of anemia in type 1 diabetes (T1D) children, compare them to results obtained in the control group, and estimate their relation to BMI SDS. METHODS 94 (59% ♀) T1D children without other autoimmune disorders, aged 12.5 ± 4.1 years, T1D duration: 4.2 ± 3.6 years, HbA1c 7.3 ± 1.5% (57 ± 12.6 mmol/mol). Sex- and age-matched controls (43 children). In all children, anthropometric measurements, the blood count, iron turnover parameters, and vitamin B12 concentration were taken. RESULTS T1DM children had significantly higher red cell distribution width (RDW) (13.6 versus 12.6%; p < 0.001), hepcidin (0.25 versus 0.12 ng/ml; p < 0.001), and vitamin B12 concentrations (459 versus 397 pg/ml; p < 0.01) and lower TIBC (59.09 versus 68.15 μmol/l; p < 0.001) than in the control group. Logistic regression revealed that RDW, TIBC (both p < 0.001), and hepcidin (p < 0.05) significantly differentiated both groups. In T1DM children, BMI SDS negatively correlated with vitamin B12 (p < 0.01) concentration and mean corpuscular hemoglobin concentration (p < 0.05) and positively with TIBC (p < 0.01) and HbA1c (p < 0.001). CONCLUSIONS Patients and controls differed especially in terms of RDW and TIBC. In studied T1DM children, BMI SDS was associated to iron metabolism parameters and vitamin B12 concentration.

Abstract
BACKGROUND The cause of multiple sclerosis (MS) is currently unknown, but it is thought that oxidative damage and iron metabolism mechanisms are involved. The aim of this study was to examine ceruloplasmin concentration in MS patients based on various immunomodifying therapies and to test the effect of antioxidative melatonin on ceruloplasmin levels. MATERIAL AND METHODS This prospective study included 102 MS patients and 15 healthy controls. Patients were divided into groups according to different immunomodifying therapies: interferons beta 1a, interferons beta 1b, glatiramer acetate, mitoxantrone, and immunomodifying pre-treatment (A, B, G, Mx, and P groups, respectively), and the relapse R group. MS patients were supplemented with melatonin for 3 months. Serum ceruloplasmin concentrations, EDSS, brain MRI, serum C-reactive protein level, and white blood cell count were examined. RESULTS The results indicated significantly increased levels of ceruloplasmin in MS patients. No differences in ceruloplasmin concentrations between the relapse group and controls were observed. In A and G groups, ceruloplasmin levels before and after melatonin were similar to levels in controls. In group B, ceruloplasmin concentration was significantly higher vs. control and relapse groups. After melatonin administration in group B, ceruloplasmin levels decreased. Ceruloplasmin concentrations in the Mx group were significantly higher compared to controls. CONCLUSIONS We found for the first time that ceruloplasmin concentration in MS patients varies depending on different immunomodulatory treatment and decrease after 3 months of melatonin administration. Ceruloplasmin could be a valuable serum marker for the chronic demyelinating process participating in oxidative stress mechanisms, as well as a neurodegenerative marker, but not a marker of acute-phase MS.

Abstract
BACKGROUND To investigate the effects of obesity on CD47, phosphatidylserine (PS) exposure, and Caspase-8 and Caspase-3 activities in erythrocytes. METHODS The study included 25 morbidly obese patients and 20 healthy people as the control group. We evaluated CD47 expression on the red blood cell (RBC) membrane surface and eryptosis markers such as PS externalization and caspase activity using flow cytometric analyses. RESULTS CD47 expression on the RBC surface was significantly lower in obese patients than in the control group (P = 0.000001). We did not find significant differences in the Caspase-3 and Caspase-8 activities between the obese and nonobese control groups. Additionally, we did not find differences in PS exposure on erythrocyte membranes. The fibrinogen levels were higher in the obese group than they were in the control group (P = 0.00002). Correlations between CD47 expression and body mass index (r = -0.65; P = 0.0004), waist circumference (r = -0.54; P = 0.0052), and fibrinogen (r = 0.57; P = 0.0024) were found. Univariate analyses revealed that body mass index, waist circumference, hip circumference, and fibrinogen levels were potential predictors of CD47 expression. Multivariate analyses found that fibrinogen levels (β = 0.4708; P = 0.045) independently predicted CD47 expression. CONCLUSIONS The study demonstrated that CD47 expression is decreased on the surface of RBCs in obese subjects. These changes in CD47 expression on the RBC surface may be an adaptive response to hyperfibrinogenemia associated with obesity. © 2015 International Clinical Cytometry Society.

Abstract
The age-related deterioration of health condition associated with progressive impairment of innate and adaptive immunity was defined as the aging of the immune system (also known as immunosenescence). Many changes occur within the immune system with age, including in particular quantitative changes in populations and subpopulations of cells resulting in dysfunction of the immune system. Elderly patients often have chronic systemic low grade inflammation process which is an effect of the inflammatory mediators secretion. Changes in the levels of mediators have a negative impact on coexisting disease and body's ability to fight infections. The purpose of the paper is to characterize the changes in proportions and functions of immune cells during the aging.

Abstract
Background Chronic spontaneous urticaria (CSU) is an immune-inflammatory disease, characterized by acute phase response (APR) and immune activation. There has been increasing evidence showing that vitamin D deficiency/insufficiency is associated with increased incidence and/or severity of immune-inflammatory disorders. Aim To assess relationship between vitamin D status and C-reactive protein (CRP), a nonspecific inflammatory marker of CSU activity. Methods Concentrations of CRP and 25-hydroxyvitamin D [25(OH)D], a biomarker of vitamin D status were measured in serum of CSU patients and compared with the healthy controls. Results Serum 25(OH)D concentration was significantly lower in CSU group as compared with the normal subjects. The prevalence of vitamin D deficiency (< 20 ng/ml) was significantly higher in patients with CSU than among normal population. There were no significant differences in prevalence of 25(OH)D insufficiency between the groups. Serum CRP concentrations were significantly higher in CSU patients as compared with the healthy subjects. There were no significant correlations between CRP and 25(OH)D concentrations in CSU patients. Conclusions CSU is associated with lower serum 25(OH)D concentration and higher prevalence of its deficiency. The results failed to show any effect of vitamin D status on circulating CRP concentrations in CSU. A potential role of vitamin D in pathogenesis and/or additive therapy of CSU needs to be examined in other cohorts of CSU patients as well as in larger studies.

Abstract
Chronic spontaneous urticaria (CU) is associated with activation of the acute phase response (APR). Nevertheless, APR-associated proteins have not been well characterized as potential biomarkers of the disease severity. To assess the pattern of complement proteins C3 and C4 – the acute phase reactants in patients with CU. C3, C4 and CRP concentrations were measured in serum of 70 patients showing different degrees of urticarial severity as well as in 33 healthy subjects. Serum C3 and C4 concentrations were significantly increased in CU patients as compared with the healthy subjects and exceed the normal lab range by about 5% and 10%, respectively. Significant differences were found between patients with mild and increased CU severity. In addition, significant correlations were observed between C3, C4 and CRP concentrations. More severe CU is characterized by higher production of C3 and C4 complements accompanied by parallel changes in CRP concentration.

Abstract
Background Our previous findings showed the importance of analysing the peripheral markers of acute phase response (APR) activation, C-reactive protein (CRP) and IL-6 in the context of urticaria activity and severity. However, these biomarkers do not reliably differentiate between APR to infectious and the disease severity. Aim In order to investigate a possible association between the immune-inflammatory activation markers CRP and procalcitonin (PCT). Methods Serum PCT and CRP concentrations were measured in patients with CU of varying severity as well as in healthy subjects. Results Serum PCT and CRP concentrations were significantly increased in more severe CU patients when compared to healthy controls and mild CU, and within the CU population there was a significant correlation between concentrations of PCT and CRP. Serum PCT concentrations remained within normal ranges in most CU patients and were only slightly elevated in some severe CU cases. Conclusions PCT serum concentration may be only slightly elevated in some cases of severe CU. Upregulation of PCT synthesis accompanied by parallel changes in CRP concentration reflects a low-grade systemic inflammatory response in CU. PCT should be considered as a better marker than CRP to distinguish between APR to infection and an active non-specific urticarial inflammation.

BACKGROUND Thymus and activation-regulated chemokine (TARC/CCL17) and cutaneous T cell-attracting chemokine (CTACK/CCL27) belong to the CC chemokine family, which plays an important role in immune-inflammatory processes. It has been demonstrated that serum concentrations of TARC and CTACK are increased in patients with various allergic diseases. AIM To compare serum TARC and CTACK concentrations between children with different clinical manifestation of mast cell-dependent diseases, such as atopic allergy and urticaria. METHODS A total of 87 children including 26 with mild to severe atopic dermatitis (AD), 43 children with controlled allergic asthma symptoms (treated and untreated with anti-inflammatory drugs), and 18 children with urticaria were recruited into the study. The control group consisted of 31 healthy non-atopic children. RESULTS Serum concentrations of TARC and CTACK were significantly higher in children with AD than in healthy controls. No significant differences in serum concentrations of the chemokines between asthmatics, urticaria patients, and healthy controls were found. The severity of AD symptoms significantly correlated with serum CTACK and TARC concentrations. CONCLUSION These findings, in conjunction with earlier data, indicate that differences may exist in circulating concentrations of TARC and CTACK, between patients with atopic allergy and urticaria.

Abstract
The ageing of the population makes the health problems of elderly people a major issue in the work of various specialists. More and more people show cognitive functions disorders from minor to considerable ones. The most common cause of dementia is Alzheimer's disease. The diagnostic criteria of dementia in the course of Alzheimer's disease or the criteria of vascular dementia are described in this article. Although we mention the scales focused on cognitive functions disorders.

Abstract
Chalcones and dihydrochalcones exhibit chemopreventive and antitumor activity. TRAIL (tumor necrosis factor-related apoptosis-inducing ligand) is a natural endogenous anticancer agent. We examined the cytotoxic and apoptotic effect of chalcones and dihydrochalcones on TRAIL-mediated apoptosis in LNCaP prostate cancer cells. The cytotoxicity was evaluated by the MTT and LDH assays. The apoptosis was detected using annexin V-FITC by flow cytometry and fluorescence microscopy. The DeltaPsim was evaluated using DePsipher staining by fluorescence microscopy. Our study showed that two tested chalcones (chalcone and 2',6'dihydroxy-4'-methoxychalcone) and three dihydrochalcones (2',6'-dihydroxy-4'4-dimethoxydihydrochalcone, 2',6'-dihydroxy-4'-methoxydihydro- chalcone, and 2',4',6'-trihydroxydihydrochalcone, called phloretin) markedly augmented TRAIL-induced apoptosis and cytotoxicity in LNCaP cells and confirmed the significant role of chalcones in chemoprevention of prostate cancer.

Abstract
Chalcones exhibit chemopreventive and antitumor effects. Tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) is a naturally occurring anticancer agent that induces apoptosis in cancer cells and is not toxic to normal cells. We examined the cytotoxic and apoptotic effect of five chalcones in combination with TRAIL on prostate cancer cells. The cytotoxicity was evaluated by the MTT and LDH assays. The apoptosis was determined using flow cytometry with annexin V-FITC. Our study showed that all five tested chalcones: chalcone, licochalcone-A, isobavachalcone, xanthohumol, butein markedly augmented TRAIL-mediated apoptosis and cytotoxicity in prostate cancer cells and confirmed the significant role of chalcones in chemoprevention of prostate cancer.

Abstract
AIM OF STUDY To define a relationship between emergency and elective indications for cesarean section and quantitative changes of percentage and quantity of T and B lymphocytes and their subpopulations in healthy full-term neonates. MATERIAL AND METHODS The study included 43 healthy neonates born in the years 1998 - 2003 in the Department of Perinatology and Gynecology of Silesian Medical University in Zabrze, Taking into account operative delivery, a group of 43 full-term neonates born by cesarean section were examined, including 25 neonates with elective indications [Ibe] and 18 with emergency indications (Ibn). Immunological studies included evaluation of the percentage of T and B lymphocytes and of their subpopulations in umbilical blood. Our study applied a method of umbilical blood sampling with the following red blood cells lysis. RESULTS The study showed that mean number of CD3+, CD23+, CD25+ lymphocytes and mean percentage and number of CD8+ lymphocytes in full-term neonates born by elective Cesarean was statistically significantly lower than in neonates born by emergency Cesarean section. No statistically significant differences were found in mean values of other parameters among the study groups. CONCLUSIONS Cesarean section performed in a mother with emergency indications can favor an increase of mean quantity of T lymphocytes, cytotoxic - suppressor T lymphocytes, activated T lymphocytes, B CD23 lymphocytes in full-term neonates.

Abstract
AIM OF STUDY To define to what degree time and the way of delivery cause changes in CD3+ lymphocytes and their subpopulations CD4+, CD8+, CD25+ and CD19+ lymphocytes and their subpopulations CD5+, CD23+. MATERIAL AND METHODS 49 healthy neonates born in the years 1998-2003 in the Clinical Ward of Perinatology and Gynecology of Silesian Medical University in Zabrze were examined. Taking into account the time of pregnancy and the way of delivery the children were divided into the following groups: Group Ib--23 full-term neonates born by Cesarean section, including 15 neonates with elective indications (Ibe), 8 with emergency indications (Ibn). Group IIb--26 pre-term neonates born by Cesarean section, including 18 with elective indications (IIbe) and 8 with emergency indications (IIbn). Our study applied a method of umbilical blood sampling with the following red blood cells lysis. RESULTS Statistically significant lower mean number of B CD5+ lymphocytes was found in full-term neonates born by Cesarean section in comparison to pre-term neonates born by the same method. Similar differences concern full-term and pre-term neonates born by elective Cesarean section. Statistically significant lower mean number of CD3+, CD4+ and CD25+ lymphocytes was found in pre-term neonates born by elective Cesarean section in comparison to pre-term neonates by emergency Cesarean section. CONCLUSIONS Time of pregnancy termination in a mother by Cesarean section can be related to the occurrence of statistically significant changes in B CD5+ lymphocytes quantities in her neonate. Emergency Cesarean section in a mother can be related to the increased quantity of T lymphocytes, helper T lymphocytes, activated T lymphocytes in her pre-term born neonate. No statistically significant differences were found in mean values of other immunological parameters among study groups.

Abstract
The adverse transfusion reaction is usually defined as an unwanted reaction occurring in a recipient during or after a blood transfusion or its components. Adverse reaction can occur even in 10% of recipients. The after transfusion reactions can be divided with regard to its causes: infectious and non-infectious, of immunologic and non-immunologic. Blood component transfusions can be related to unfavorable transfusion reaction of early or delayed character.

Abstract
PURPOSE The aim of the present study was to compare the blast immunophenotype of acute lymphoblastic leukaemia (ALL) at diagnosis and at relapse and to define the most frequent shifts in marker expression. PATIENTS AND METHODS Bone marrow samples from 14 patients were analyzed by flow cytometry both at diagnosis and at relapse - in 12 patients with B-cell precursor (BCP)-ALL and in 2 patients with T-ALL. RESULTS The conversion in blast immunophenotype was observed in 12 out of 14 patients (86%). Antigen CD34 turned out to be the most unstable antigen - the shift in the signal expression was present in 57% of BCP-ALL and in both T-ALL cases. Regarding B-lineage markers, the shifts most frequently concerned CD20 (shifts present in 41.5% of cases) and CD22 (27%). Among the T-lineage markers: CD3, CD4 and CD8 demonstrated the highest incidence of altered signal expression. On the other hand, the most stable antigen included CD19 and CD10 for the BCP-ALL group and CD1a, CD2, CD5, CD7 for T-ALL patients. Expression of HLA-DR, TdT and CD45 antigens remained unchanged in both BCP-ALL and T-ALL groups. CONCLUSIONS The results of the present study support the requirement to monitor at least two different leukaemia specific antigen combinations for detection of MRD to prevent a false-negative result and to increase the effectiveness of monitoring minimal residual disease.

Abstract
UNLABELLED Staphylococcus aureus skin colonization in atopic dermatitis (AD) patients exacerbates disease activity. Nasal and throat S. aureus carriage may be also implicated in the clinical course of allergic rhinitis and asthma. The aim of the study was to evaluate the frequency of skin, nasal, throat S. aureus colonization in patients with AD and asthma and assess if presence of this bacteria on the skin may be related with degree of sensitization. MATERIAL AND METHODS Swabs for microbiological analysis were taken from affected skin, anterior nares and throat from 40 children with AD, 59 children with asthma and 56 healthy controls. Following lymphocyte subsets: CD3+, CD4+, CD8+, CD3+CD25+, CD4+CD25+ were measured using flow cytometry. RESULTS Nasal and throat S. aureus colonization was more frequent in atopic children. S. aureus was found in the skin lesions in 97.5% examined children with AD. Percentage of CD8+ was decreased but the number of CD4+, and CD4+CD25T+ cells was elevated compared with healthy. Total IgE and sIgE Der. pteronyssinus and Der. farinae as well SPT (Skin Prick Test) wheel size were higher in AD children compared to asthma. SCORAD was correlated with total and sIgE (mite, pollen) and number of S. aureus and increasing skin reactivity skin. The degree of sensitization was correlated with patient's age, duration of AD and asthma and number of CD3+, CD4+ and percentage of CD4+CD25+ only in AD patients. Severity of asthma was correlated with FEV1 and total IgE. CONCLUSIONS Staphylococcus aureus skin colonization in AD children increases disease activity and degree of sensitization measured by SPT wheel size and results in imbalance of peripheral blood T cells.

Abstract
Atopic dermatitis (AD) is a chronic inflammatory skin disorder, which is associated with an increased expression of Th2 cytokines with concomitant decrease in IFN-gamma production by circulating CD4+ and CD8+ T cells. The skin of patients with AD is often colonized by Staphylococcus aureus, which may reflect in changes in immunological parameters. The aim of the study was flow cytometric measurement of some peripheral blood lymphocyte subsets expressing naive/memory marker (RA/RO) and activation marker (CD25) as well as intracellular production of IFN-gamma by peripheral blood CD4+ and CD8+ T cells from varied severity AD children and determine the impact of S. aureus skin colonization on cytokines profiles. There was a significant increase in the percentage of CD4+ and CD8+ T cells producing IL-4 and IL-13 and decrease in the percentage of CD4+ and CD8+ T cells producing IFN-gamma upon in vitro stimulation with phorbol 12-myristate 13-acetate and ionomycin in children with AD compared to healthy ones. The absolute number of CD4+ and CD8+ T cells expressing memory marker CD45RO was elevated as compared with controls. The severity of AD was positively correlated with the percentage of lymphocyte subsets: CD45RO+, CD4+CD45RO+, and the percentage of CD3+ and CD4+ expressing CD25 as well as the number of S. aureus on the skin. In conclusion, both CD4+ and CD8+ memory T cells are involved in the immunopathogenesis of AD. S. aureus skin colonization is related with disease severity and changes in expression of CD45RO and CD25 on T cells. A decrease in the percentage of CD4+ and CD8+ T cells producing IFN-gamma in AD children may explain propensity for skin infection.

Abstract
It has been postulated that ionizing radiation generates reactive oxygen species (ROS). ROS are annihilated by an intracellular enzymatic system composed mainly of superoxide dismutase (SOD), catalase (CAT) and glutathione peroxidase (GPx). Workers of X-ray departments are occupationally exposed to long-term low levels of ionizing radiation, which may affect their antioxidant status. Erythrocyte activities of SOD, CAT and GPx were measured in 45 workers of X-ray departments and 30 persons who constituted the control group. Subgroups with respect to sex and cigarette smoking were selected. Colorimetric method was used for determination erythrocyte activities of SOD, CAT and GPx. A significant decrease of GPx, SOD and CAT activity in workers as compared to controls was observed. Lower activity of SOD and GPx in female and GPx in male subgroup was found. SOD was significantly more elevated in smoking workers than in the non-smoking staff. Moreover non-smoking employees showed lower SOD and GPx activity in comparison to the non-smoking control. GPx decrease was found in smoking workers in comparison to the smoking control. Additionally, smoking workers showed lower activity of GPx and CAT compared to non-smoking control.

Abstract
CD30 was initially described as Ki-1 Ag on Reed-Sternberg cells of Hodgkin's lymphoma and its and CD30L(+) expression on T cells in placenta were equally frequent in the atopic and non-atopic women. In this article we present a study of CD30 mean fluorescence intensity (MFI) on CB T CD4(+) cells. We tested the hypothesis that in newborns with atopy family history there is a changed CB T cells response after antigen stimulation comparing with those without atopy family history. The study population consisted of 31 newborn babies (29-breastfed, two non-breastfed) and their mothers. Eleven of them had positive and 20 had negative atopy family history. Performed tests included cord blood, which was a subject to flowcytometry analysis and was cultured for 24 h, cytokine production was measured (IFN- gamma, IL-4 and IL-12). Secondly, we measured total maternal and cord blood IgE levels. We studied CD30 MFI as in our studies in larger group of newborns, CD30 expression on CD4(+) T cells appeared to be very low. MFI of CD4(+) CD30(+) after PHA-stimulation (213.55: range: 41.77-434.51) was significantly increased compared to MFI of CD4(+) CD30(+) before PHA-stimulation (43.63: range 28.67-134.67)(p </= 0.001). Newborns with and without atopy family history were analyzed. We found no difference between MFI of CD4(+) CD30(+) on non-stimulated T cells in non-atopic (43.80: range 28.66-134.66) and atopic (43.30: range 29.12-80.92) (p > 0.05). After PHA stimulation MFI of CD4(+) CD30(+) in non-atopic (273.05 (range: 42.9-434.51) was significantly increased compared with the atopic newborns to MFI of 87.1 (range: 41.78-241.42) (p = 0.00). We have not found any correlation between MFI of CD4(+) CD30(+) and total maternal and total CB IgE levels. The role of CD30 in immunological response needs further research studies.

Abstract
The role of the type-2 T helper (Th2) cell-mediated immune response in the immunopathogenesis of atopic dermatitis (AD) is well documented. Whether polarized immunoresponse is confined to antigen-specific T cells or is distributed among all T cell subsets is still controversial. We investigated frequencies of interleukin-2 (IL-2), IL-4, interferon-gamma (IFN-gamma), and tumor necrosis factor-alpha (TNF-alpha) producing CD3(+) and CD4(+) T cells in peripheral blood from children with atopic dermatitis and healthy subjects with and without in vitro stimulation. Children with severe AD had a significantly lower percentage of CD4(+) T cells spontaneously expressing IL-4 compared with healthy controls (p <0.01). Polyclonal stimulation significantly increased cytokine production in both AD patients and healthy individuals. Frequencies of CD3(+) and CD4(+) producing IL-2, IL-4, IFN-gamma, and TNF-alpha after in vitro stimulation with phorbol-12-myristate 13-acetate (PMA) + ionomycin were comparable in the AD and control groups. In response to PMA/ionomycin, children with AD and asthma symptoms had a significantly lower percentage of CD3(+) T cells producing TNF-alpha. We failed to demonstrate evidence of an imbalance with respect to type-2 cytokine productions in children with AD. Comparable induction of Th1 and Th2 cytokines in polyclonally stimulated peripheral CD3(+) and CD4(+)T cells from AD patients and controls puts into question the polarized Th2 immune response as a general characteristic of T cells in children with atopic dermatitis.

Abstract
OBJECTIVES Malnutrition and loss of appetite represent a serious problem in children with chronic renal failure. Ghrelin is a newly described hormone involved in control of growth hormone secretion, stimulation of food intake, and regulation of energy balance. METHODS Plasma ghrelin levels were compared between 12 children on automated peritoneal dialysis (APD) and 9 children on conservative treatment of chronic renal failure. Eight healthy children matched for age and body mass index (BMI) served as a control group. RESULTS Plasma ghrelin levels were similar in children on APD (698.3 +/- 59.7 pg/mL) and children on conservative treatment (675.4 +/- 41.9 pg/mL) compared to healthy controls (700.1 +/- 24.7 pg/mL). There was no difference in plasma ghrelin levels in children with chronic renal failure regardless of the method of treatment (peritoneal dialysis vs conservative treatment). The plasma ghrelin index was similar in all three investigated groups: APD 40.2 +/- 8.7 vs conservative treatment 39.1 +/- 5.6 vs controls 41.0 +/- 7.8 (pg/mL)/BMI (kg/m2). Plasma ghrelin levels did not correlate with age, duration of dialysis treatment, height, weight, BMI, creatinine and urea levels, adequacy parameters, or nightly glucose load. CONCLUSION Plasma ghrelin levels in children on APD were not different from levels in children on conservative treatment or healthy controls with comparable BMI. The persistent state of toxic influence of uremic end-products could be responsible for such a lack of correlation with anthropometrical parameters. Further studies on a larger group of children on APD are needed to clarify the effect of ghrelin on nutritional status in children with chronic renal failure.

Abstract
Ionizing radiation affects the expression of adhesive and co-stimulatory molecules in lymphocytes. The physiological function of cellular isoform of prion protein (PrPc) is little known. Evidences indicate a link between lymphocytes activation and PrPc expression on their surface; however, no direct effect of radiation on PrPc level in these cells was investigated. The objective of this study was to determinate the effect of low doses of ionizing radiation on the expression of PrPc on the surface peripheral blood lymphocytes in the women operating X-ray equipment. In 36 female workers and 30 persons of the control group the PrPc expression on CD3 (T lymphocytes), CD4 (T helper), CD8 (T cytotoxic) and CD19 (B lymphocytes), as well as the percentage of lymphocytes with PrPc on their surface, were tested. Subgroups with respect to age and length of employment were selected. A significant increase was observed in PrPc expression on CD3 and CD4 with lowered PrPc level on CD8 and percentage of CD8 cells with PrPc in workers compared to control. The PrPc level did not show significant changes in subgroups in relation to age (below and over 40 years old) both in the investigated and control groups, whereas a lower percentage of PrPc expressing CD19 cells showed in employed women below 40 years of age. A significant decrease was found in PrPc expression on the surface of CD3, CD4 and CD8 cells in the subgroup employed for over 10 years than in the subgroup with less than 10 years of employment.

Abstract
OBJECTIVE Ghrelin is a natural ligand of the growth hormone secretagogue receptor and has been shown to be a potent stimulant of GH secretion. It has also orexigenic effects and regulates energy homeostasis. Recent studies claim that ghrelin influences the androgen level and probably takes part in PCOS pathomechanism. The aim of the study was an assessment of ghrelin level in plasma in women with PCOS before and after the treatment and ghrelin's influence on androgen level change. MATERIAL AND METHODS The study included 25 women with the diagnosed PCOS (mean age 25.3+/-4.05 yr). The tests were done twice: before the treatment and after 6-month therapy with Diane 35 (cyproterone acetate 2 mg with ethinylestradiol 35 mug). Following hormones were measured: ghrelin, free testosterone, androstendione, dehydroepiandrosterone sulfate, 17-OH-progesterone and estradiol. RESULTS The received results in both groups were compared with the control group (11 healthy women, mean age 26.0+/-2.6 yr). No statistically significant differences in ghrelin levels before (187.8+/-8.1 fmol/ml) and after the therapy (185.6+/-9.5 fmol/ml) were found. Similar results were received when two groups of women compared with the control (186.5+/-8.7 fmol/ml). No correlations between ghrelin and androgen levels were confirmed. CONCLUSIONS Final conclusion is that there is no direct impact of ghrelin level on PCOS pathogenesis, however, its role in development of obesity, hyperinsulinemia and insulin resistance co-occurring with metabolic disorders syndrome cannot be excluded.

Abstract
Treatment-related immunosuppression in patients with acute lymphoblastic leukemia (ALL) is associated with increased susceptibility to infectious diseases, also after the treatment. The aim of the present study was the detailed evaluation of T lymphocyte subsets in peripheral blood in children after treatment of ALL. All children were treated according to the BFM 90 protocol. The patients were divided into 5 groups of 30 children in each, depending on the time from cessation of the ALL treatment. A control group consisted of 30 healthy children subjected to elective "1-day" surgery. The children's age ranged from 6 to 18 years. The examinations were performed in FACScan flow cytometer with the use of wide set of monoclonal antibodies: CD3, CD4, CD8, TCRalphabeta, TCRgammadelta, CD19, CD25, CD45RA, CD45RO, CD69, HLA-DR, CD16 and CD56, which particularly allowed detailed analysis of T lymphocytes. The results showed that most parameters in children 1 year after ALL treatment completion were similar to healthy children. However, we observed persistently low CD4+ T cell numbers, both CD45RA+ as well as CD45RO+ subsets as compared to the control group. This might reflect decreased regenerative potential of immunological system in children 1 year after ALL treatment.

Abstract
Clinical symptoms, IgE, and eosinophil counts are insufficient for establishing diagnosis of asthma in young children. It has been suggested that other serum markers might be useful for supporting diagnosis. The aim of the study was to determine serum levels of IL-4, IL-10, and IL-12 in young children with recurrent wheezy bronchitis. We investigated if there was a relationship between those markers and the maintenance clinical symptoms during a 2-year follow-up period. The study involved 30 young children (average age--22.5 months) with recurrent wheezy bronchitis. Control group consisted of 15 healthy children at the same average age. The serum levels of IL-10 (p<0.0006) and IL-12 (p<0.000005) were significantly increased and the serum level of IL-4 was significantly decreased (p<0.00009) in children with wheezing compared with healthy control. However the serum level of IL-10 (p<0.004, R=0.5) and IL-12 (p<0.001, R=0.54) was positively correlated with a number of episodes wheezing in the past. Children with wheezing and skin rash showed a significantly higher level of IL-4 (p<0.02) and lower levels of IL-10 (p<0.0008) and IL-12 (p<0.005) compared with children without skin rash. No statistically significant differences in serum levels of IL-4, IL-10, and IL-12 were observed between children with persistent wheezing during a 2-year follow-up period and children without respiratory symptoms. This study suggested a potential role cytokines in recurrent wheezing, but follow-up of the children is needed to evaluate the prognostic value of serum cytokines for development asthma in later childhood.

Abstract
BACKGROUND Allergic inflammation is mainly driven by type 2 T helper cells. The aim was to assess the changes in production of type 1 and 2 cytokines by CD3+ T cells dependent on natural exposure to allergens in subjects with intermittent allergic rhinitis (IAR) and in non-atopic subjects. MATERIAL A total of 13 patients with IAR and 13 healthy non-atopics were recruited into the study. 11 patients with IAR were examined during the grass pollen season and 11 patients outside the season, 9 of them were assessed on both occasions. METHODS A flow cytometric assessment of intracellular expression of IL-2, IL-4 and IFN-gamma by CD3+ cells was performed. For statistical analysis non-parametric tests were used. RESULTS A tendency to decreased production of IL-4 outside the season was observed (6.94% [3.42-13.33] in season vs. 2.06% [0.7-3.6] out of season). The production of IL-4 was higher in the rhinitic group in the season than in the control group (1.93% [1.07-4.97], p=0.0034) and production of IL-2 was higher both in and outside the season (9.1% [3.94-15.09] and 10.0% [4.79-25.35] vs. 3.64% (2.64-5.03), p=0.037 and 0.045, respectively). IL-4/IL-2 and IL-4/IFN-gamma ratios were higher in the IAR group in the season than outside the season. CONCLUSION A tendency towards a switch from a predominant type 2 response during natural allergen exposure to its suppression outside the season was found, together with a stable type 1 response.

Abstract
OBJECTIVES Workers of x-ray departments are occupationally exposed to long-term low levels of ionizing radiation. The aim of the study was to investigate the influence of occupational exposure of low-level x-ray radiation on immunoglobulin and C-reactive protein (CRP) concentrations in radiology workers. MATERIALS AND METHODS In the study group of 41 x-ray department workers and the control group composed of 32 persons, immunoglobulins (IgM, IgG, IgA) and CRP concentrations were analyzed. The study group was subdivided by gender and smoking habit. RESULTS A significant decrease in IgG level was found in the workers and the female subgroup. The same observation was made when smokers and nonsmokers of both groups were compared. Smoking workers showed lower concentrations of IgA than non-smokers. The remaining results of immunoglobulin and CRP concentrations did not show significant differences. CONCLUSIONS Occupational exposure to low levels of ionizing radiation is associated with suppressive influence on the immunoglobulin production, especially IgG. In addition, smoking decreases the production of IgA in radiology workers.

Abstract
BACKGROUND The aim of the study was the evaluation of CD3+/TCR alphabeta and CD3+/TCR gammadelta lymphocytes in the cord blood of the preterm neonates. METHODS The study included 26 term neonates as a control group delivered both by spontaneous labor and by cesarean section and 41 preterm neonates: (i) by cesarean section due to abruptio placentae, (ii) by cesarean section due to the danger of intrauterine asphyxia, (iii) by cesarean section due to preterm rupture of membrane (PROM), and (iv) by spontaneous labor. Immunological analysis was performed in the flow cytometer FACScan, using anti-CD3, anti-TCR alphabeta and anti-TCR gammadelta monoclonal antibodies from Becton Dickinson (San Jose, California USA). RESULTS It was shown that the way of delivery does not influence the value of CD3+/TCR alphabeta lymphocytes. A decrease of the percentage and number of CD3+/TCR gammadelta lymphocytes was found in neonates delivered by elective cesarean section. However, the danger of intrauterine fetal asphyxia, as a reason for preterm delivery, influenced a considerable increase of the number of CD3+/TCR alphabeta and CD3+/TCR gammadelta lymphocytes. Perinatal risk factors (abruptio placentae, PROM) were related to the lowest number of CD3+/TCR gammadelta lymphocytes in the blood of the preterm neonates. CONCLUSION The obtained results suggest that in spite of considerable immaturity, both a term and preterm neonate is prepared for the immune response and is able to activate cell mechanisms. The precise mechanism that links CD3+/TCR alphabeta and CD3+/TCR gammadelta lymphocytes and pathological condition of preterm birth remains unclear.

Abstract
The immunosuppressive effect of cytotoxic drugs, basic therapeutic agents in the treatment of childhood acute leukemias, requires monitoring of the immune system following cessation of therapy. The cytokines are soluble proteins that play a key role in the immunoregulation of the lymphocyte function. The cytokines regulate growth, differentiation and function of various cells in normal conditions. The aim of our study was to estimate serum levels of IL-2, IL-6, IL-8, IL-10 and TNF-alpha in children with acute lymphoblastic leukemia (ALL) after cessation of chemotherapy. The study involved 150 children with ALL. This group consisted of: 30 children 1 month after treatment cessation; 30 children, 3 months later; 30 children 6 months later; 30 children, 9 months later and 30 children, 12 months later. The control group consisted of 30 healthy children. The levels of the cytokines under study were assayed using the immunoassay kits (R&D Systems, USA). During the study significant differences in TNF-alpha, IL-2 and IL-8 serum concentrations were observed among treated children and controls. However there were no differences in IL-6 and IL-10 concentrations.

Abstract
BACKGROUND The Th1/Th2 paradigm is considered to be responsible for the development of many immunological disorders, including atopic diseases and diabetes mellitus type 1. So far, however, no unequivocal markers identifying the two subpopulations of T cells have been found. OBJECTIVE To examine the expression of two putative markers of Th1-mediated disorders, CD26 and lymphocytes activation gene-3 molecules, on CD4+ and CD8+ lymphocytes in the peripheral blood of atopic and diabetic donors. METHODS 11 patients (9 males/2 females, age range: 21-29, median age: 23) suffering from episodic atopic bronchial asthma (AO group) and 11 patients (9 males/2 females, age range: 33-47, median age: 42) with insulin-dependent diabetes mellitus (DM group) were included into the study. Atopy was excluded in all diabetic patients. The following T cell subsets were analyzed by flow cytometry (FAC-Scan): CD8+CD26+, CD4+CD26+, CD4+LAG-3+, CD8+LAG-3+, and CD56+. Nonparametric tests were used for statistical analysis, and results were expressed as median and quartile range. RESULTS Among all analyzed T cell subsets, the number of CD4+LAG-3+ and CD8+LAG-3+ cells was significantly higher in the A0 group--8.3% (5.4-11.7) vs DM 5.4% (3.9-5.9), p < 0.05, and 13.3% (8.8-19) vs DM: 7.1% (6.2-8.3), p < 0.008, respectively. The ratio between CD4+/CD8+ subsets was similar in both groups: CD4+CD26+/CD8+CD26+--AO: 7.2 (5.3-10.1); DM: 6.4 (5.5-12.6), p = 0.77 and CD4+LAG-3+/CD8+LAG-3+--AO: 0.64 (0.58-0.67); DM: 0.71 (0.64-0.78), p = 0.082. CONCLUSION The results suggest that the two examined putative markers of type 1 T cells do not discriminate between Th1- and Th2-dominated responses.
