Abstract
OBJECTIVES To compare utility of CA125, human epididymis protein 4 (HE4), risk of ovarian malignancy algorithm (ROMA), risk of malignancy index (RMI) and subjective assessment (SA) in preoperative diagnosis of ovarian tumors. MATERIAL AND METHODS Research was conducted among 456 patients qualified for surgery due to ovarian tumor. Preoperatively, CA125 and HE4 serum levels were estimated, and transvaginal ultrasound was performed. ROMA and RMI values and SA qualifications were obtained. Results were compared with pathomorphological findings. RESULTS Receiver Operating Characteristic (ROC)-Area Under Curve (AUC) values for CA125, HE4, ROMA, RMI and SA in preoperative diagnosis of malignant lesions were 0.819, 0.909, 0.911, 0.895 and 0.895, respectively. Combinations of biochemical and sonographic methods increased sensitivity in diagnosis of ovarian tumors. Combinations utilizing serum HE4 concentrations were most useful. CONCLUSIONS CA125, HE4, ROMA, RMI and SA proved to be useful in preoperative diagnosis of ovarian tumors. HE4 and ROMA occurred to be the most useful. Ultrasonographic methods are considerably useful in diagnosis of ovarian tumors. RMI and SA present similar overall diagnostic value.

Abstract
OBJECTIVES The aim of this study was to examine the role of ghrelin, obestatin, and glutamate and their receptors in the pathogenesis of children functional constipation. METHODS Children ages 4-17 were the subject of the study: 121 children with constipation (55 boys and 66 girls), 36 patients of the same age (26 boys and 10 girls) were the controls. Expression of ghrelin, obestatin, and glutamate receptors on gastric and colon specimens taken by endoscopy were assessed. The concentration of the above agents was estimated in serum by the enzyme-linked immunosorbent assay test. RESULTS The lower median serum concentrations of ghrelin, in the constipated children than in controls were confirmed (1.9 ng/mL vs 2.6 ng/mL, P < 0.05). The expression of the metabotropic receptor 7 for glutamate (mGlu7) RNA was higher in the stomach (32.49 vs 31.47, P < 0.05), and was lower in the rectum in constipated patients compared to the control group (31.76 vs 32.62, P < 0.05). A negative correlation between the concentration of ghrelin in serum and colonic transient time (P = 0.01, rho = -0.23) was shown in the study group.Higher median expression of obestatin receptor G protein-coupled receptor39 in rectal mucosae was found in a constipated group than in the controls (29.9 vs 26.9, P < 0.05). CONCLUSION Ghrelin, and receptors for ghrelin, obestatin, and glutamate in gastrointestinal mucosa play a role in the pathogenesis of functional constipation in children.

Abstract
Epithelial ovarian cancer is a heterogeneous disease comprising several tumor types that each have multiple histopathological features and different biological behaviors. Recent morphologic and molecular genetic studies have allowed for the categorization of various types of ovarian cancer into two groups: type I and type II. Type I tumors are low-grade and are genetically more stable, while type II tumors are high-grade and genetically unstable. The determination of the type of ovarian cancer may have implications in terms of the appropriate therapeutic strategy because different prognoses and responses to chemotherapeutic agents are observed. Therefore, the current challenge is better recognition of the features of cancer cells, which may result in more individualized therapy. The aim of the current studies was to compare the ability of ovarian cancer cells isolated from tumors, which were classified as type I or type II ovarian cancer, to release pro-inflammatory and immunosuppressive cytokines and heat shock protein (HspA1A). These factors are known to facilitate tumor cell survival, invasion and metastasis. Our studies demonstrated that ovarian cancer cells isolated from patients with type II tumors released high levels of immunosuppressive cytokines (i.e., interleukin 10 and transforming growth factor β) and HspA1A in vitro. Conversely, ovarian cancer cells obtained from of type I tumors were significantly less active. We did not observe any difference in the ability of the isolated cancer cells to secrete pro-inflammatory cytokines, regardless of the type of ovarian cancer. In this study, we found that cancer cells from patients with type II tumors demonstrated more intense activity in regards to survival and metastasis, which should be considered during therapy.

Abstract
OBJECTIVE To analyze the profiles of interleukin-2 (IL-2), IL-6, IL-8, IL-10, tumor necrosis factor-alpha (TNF-alpha), transforming growth factor-beta1 (TGF-beta1) and interferon-gamma (IFN-gamma) in serum and the tumor microenvironment (cyst fluid, ascites) in women with ovarian cancer or benign ovarian tumors to find the differences in their immunological status. We also estimated serum cytokines as biomarkers to distinguish preoperatively between malignant or benign character of tumors. DESIGN Prospective study. SETTING Tertiary referral hospital. POPULATION 51 women with epithelial ovarian cancer, 26 with benign ovarian tumors of epithelial origin and 21 healthy controls. METHODS The levels of cytokines were measured using ELISA sets. RESULTS We did not found differences in the levels of IFN-gamma, TNF-alpha and IL-2 in all fluids isolated from patients with malignant or benign tumors. Women with advanced cancer had significantly higher serum IL-6, IL-10 and TGF-beta1 levels than women with early stages or benign tumors. Moreover, women with very advanced cancer in whom the optimal cytoreduction was disabled had the highest serum levels of IL-10, TGF-beta1 and IL-8. The concentrations of IL-6 and IL-8 were higher in ascites of cancer patients than in ascites of women with benign tumors. The areas under curves constructed for the selected cutoff serum cytokines levels (AUC-ROC) showed good predictive values for IL-6 (0.87), IL-10 (0.836) and IL-8 (0.797). CONCLUSIONS Our results indicate on intensified inflammatory process in women with ovarian cancer (accompanied by their immunosuppression). Preoperative analysis of serum IL-6, IL-10 and IL-8 may improve the differential diagnosis of ovarian tumors.

Abstract
Stimulation of epidermal growth factor receptor (EGFR) results in the activation of signal transducer and activator of transcription-3 (STAT3), a transcriptional factor associated with carcinogenesis. Proinflammatory cytokines are capable of activating a tumor cell death program by reducing EGFR tyrosine phosphorylation. This study aimed to identify EGFR expression in laryngeal carcinoma and determine the relationship with STAT3 and proinflammatory/regulatory cytokine secretion. An analysis of EGFR expression (membranous EGFR-m and cytoplasmic EGFR-c) was performed in tumor tissues by immunohistochemical (IHC) staining in 45 medical cases of laryngeal carcinoma. STAT3 expression in freshly isolated tumor and non-cancerous normal epithelial cells by RT-PCR was analyzed in 24 patients after total larynx resection. The concentrations of TNFalpha, IL-2, IL-6, IL-8 and IFNgamma secreted by purified peripheral blood mononuclear cells (PBMCs) or contained in whole blood samples were measured by ELISA. The relationship between EGFR and mRNA STAT3 expression as well as the level of secreted cytokines was investigated. In our study, 93.3% tumors expressed EGFR-m and 37.8% EGFR-c. It also revealed a statistically significant dependence of the EGFR status on STAT3 expression in neoplastic tissues. Tumors with IHC EGFR-m positive staining >50% of the total number of cells, as well as with EGFR-c positive staining, were characterized by the most frequent presence of STAT3 expression. Our data demonstrate a significant negative relationship between EGFR-m expression and TNFalpha concentration, and a positive connection between membranous EGFR and IL-8 or IFNgamma levels recorded in isolated PBMCs. Furthermore, this study revealed a significant relationship between EGFR-c immunoexpression and IL-8 or IFNgamma concentration. Our findings have confirmed a key role of EGFR in determining the proliferative and malignant potential of laryngeal carcinoma.

Abstract
The aim of the study was to assess the role of selected elements of innate immunity in the pathogenesis of chronic hepatitis C in children. The study comprised 20 children with chronic hepatitis C (group 1), nine healthy hepatitis C virus (HCV) seropositive children (group 2) and 18 healthy children (control group). We evaluated the expression of Toll-like receptor (TLR)2 and TLR4 on peripheral blood neutrophils, and generation of interleukin (IL)-8, IL-10, IL-12 and reactive oxygen species (ROS) by neutrophils. The performed tests demonstrated higher expression of TLR2 and TLR4 on stimulated neutrophils and of TLR4 on non-stimulated neutrophils in group 1 in comparison to HCV seropositive children and controls. In group 1, the expression of TLR2 after granulocyte colony-stimulating factor (GCSF) stimulation showed positive correlation with alanine aminotransferase and asparate aminotransferase activities, while the expression of TLR2 without stimulation and of TLR4 after GCSF stimulation also correlated with necrosis. IL-12 generation by lipopolysachcharide-stimulated neutrophils was higher in group 1 versus controls. In group 1, maximum chemiluminescence (CL) without pre-activation, both spontaneous and after formyl-methionyl-leucyl-phenylanine and phorbol-myristate-acetate (PMA) stimulation, was significantly lower than in the controls. CL after tumour necrosis factor-alpha pre-activation and PMA stimulation was still lower than in the controls, however, after opsonized zymosane stimulation it was significantly higher than in the controls. Our studies suggest the involvement of neutrophils in the pathogenesis of chronic hepatitis C in children. Neutrophils demonstrate increased expression of TLR2 and TLR4 (correlating with the features of hepatocytic damage and intensification of necrosis), inhibition of oxygen metabolism, and after TNF-alpha pre-activation higher ability to produce ROS.

Abstract
BACKGROUND Recurrent aphthous ulcers (RAU) is a chronic inflammatory disease with evidence of inappropriate immune response. This study presents the status of innate immune system in RAU. METHODS Twenty RAU patients and 19 healthy individuals were selected. The status of peripheral blood neutrophils (reactive oxygen intermediates (ROI) production, CD11b, TNF-RI and TNF-RII expression), concentration of antioxidants, sTNF-R, C3c, C4 and haemolytic activity of the complement system, as well as mannose-binding lectin (MBL), in the serum of RAU patients in active stage and in remission of the disease were determined. RESULTS Peripheral blood neutrophils were primed in RAU, which resulted in increased ROI production by resting and fMLP-stimulated neutrophils and diminished ROI production after in vitro priming. The increased expression of CD11b on resting and fMLP-stimulated neutrophils in RAU may also point to their previous in vivo stimulation. The decreased total antioxidant status of serum observed in RAU may be a result of increased ROI production by peripheral blood neutrophils. The levels of C3c, C4 and haemolytic activity of the complement system were higher in RAU than in healthy people. No significant differences between active and remission RAU were noted. CONCLUSION Presented observations confirm that the innate immune system is involved in RAU pathogenesis.

Abstract
BACKGROUND Endometriosis, uncontrolled proliferation of ectopic and eutopic endometriotic tissues, is common in women at reproductive age, and may affect fertility. The role of macrophages in the pathogenesis is well proved, but engagement of T cells in the pathogenesis of endometriosis is a matter of controversy. AIMS T-cell involvement in the pathogenesis of endometriosis was the objective of our study performed on women aged 24-46 years with diagnosed endometriosis. All the patients that were studied underwent diagnostic laparoscopy. METHODS We evaluated the distribution of T-lymphocyte subpopulations in peripheral blood (PB), peritoneal fluid (PF) and in endometriotic tissues (ET), as well as cytokines [interleukin (IL)-2, IL-4, IL-10, IL-12, interferon (IFN)-gamma] production by peripheral blood lymphocytes. IFN-gamma, tumor necrosis factor (TNF)-alpha, IL-4 and IL-6 were investigated for their intracellular presence. The experiments were carried out before and after 6 months treatment with the GnRH-Analogous Goserelin (Zeneca Pharmaceuticals). The number of performed investigations is presented. Statistical analysis was performed using Statistica/Win 5.0 software and Student's t-test, the paired Student t-test and Fisher's exact test when appropriate. RESULTS We have compared the lymphocyte subset re-distribution with regard to the American Fertility Society (AFS) stages and scores, but no differences were observed. The significant increase in CD4:CD8 ratio, the decrease in the number of natural killer (NK) cells in PB and the decrease in CD4:CD8 ratio in PF and ET of women with endometriosis was noted. The diminished IFN-gamma secretion by phytohemagglutinim (PHA)-stimulated lymphocytes in vitro derived from women with endometriosis and increased IL-4 production may be responsible for defective immunosurveillance against overgrowth of endometriotic tissues. The diminished NK cells number in PB of women with endometriosis argues for such a hypothesis. The increased deposits of proinflammatory IL-6 and TNF-alpha in the T lymphocytes of women with endometriosis may be related to T-regulatory lymphocyte function and their inability to suppress cell proliferation in endometriosis. GnRH-Analogous Goserelin treatment normalises cytokine production and induces patient recovery. CONCLUSIONS The significant functional and phenotypic differences between the lymphocytes from healthy women and women with endometriosis were noted. The diminished IFN-gamma production in relation to decreased NK cells number and the increased IL-4 production before the treatment and normalisation after the treatment suggest the involvement of the deregulated T-cell system in the growth stimulation and recruitment of endometriotic cells. The increased CD4:CD8 ratio, IL-6, TNF-alpha deposits and diminished anti-inflammatory IL-10 production by lymphocytes may participate in the pathogenesis of endometriosis, and may secondarily affect the monocyte/macrophage function.

Abstract
Innate immunity includes neutrophil inflammatory function, tissue destruction and regulatory cytokine production. Programmed cell death (apoptosis) is postulated to be a key mechanism for neutrophil elimination during inflammation. The aim of the present study was to evaluate the neutrophil apoptosis in relation to IL-8, IL-10 and IL-12 production in vitro by neutrophils of patients suffering from diabetes mellitus (DM)1 and the first-degree relatives of patients with DM1. The early stage of neutrophils apoptosis was assessed morphologically, and the later stage by DNA-binding dye propidium iodide, both after treatment with lipopolysaccharide (LPS), insulin or anti-CD95 antibody (Ab) as stimulators. CD16 (FcgammaRIII) receptor expression was also evaluated. Production of IL-8, IL-10, and IL-12 cytokine was evaluated in supernatant after neutrophil incubation for 21 h in culture medium alone, in medium in the presence of LPS, insulin or anti-CD95 antibody (Ab). Cytokine concentrations were measured by enzyme-linked immunosorbent assay (ELISA) method using commercially available kits. Our study demonstrates that LPS inhibits the early stage of apoptosis (as evaluated morphologically) of healthy donors' neutrophils. The LPS-dependent early apoptosis inhibition of neutrophil of patients with DM1 or in prediabetics was decreased in comparison with control. The later stage of apoptosis of neutrophils treated in vitro with anti-CD95 Ab of patients suffering from DM1 was decreased in comparison with prediabetics and healthy donors (propidium iodide (PI) staining). LPS-induced production of anti-apoptotic cytokines IL-8, IL-10 by neutrophils of prediabetic and patients with DM1 was increased. The formyl-methionyl-leucyl-phenylalanine (fMLP)-induced proapoptotic reactive oxygen intermediates (ROI) production was significantly higher in DM1 patients. We have concluded that neutrophils from prediabetic and diabetic patients demonstrated the misbalance in anti-apoptotic IL-8 and IL-10 cytokine and proapoptotic ROI production. LPS-dependent IL-12 overproduction by neutrophils is responsible for the switch in T helper Th1/Th2 balance to Th1 and in this way may participate in inflammation and autoimmune DM1 progression.

Abstract
The purpose of this study was to analyze the immunological characteristics of nonpregnant women with recurrent spontaneous abortions (RSA) of unknown etiology. We analyzed how differences of the immunological state of individual groups of women with RSA and various types of RSA (primary vs. secondary aborters) might influence on results of paternal lymphocytes immunization. In this prospective study the immunological characteristics of 117 nonpregnant women with unexplained RSA in comparison to 44 healthy, nonpregnant multigravid women, were analyzed. The following immunological parameters were studied: peripheral blood lymphocyte subpopulations (CD3+, CD4+, CD8+, CD3+/HLA-DR+), lymphocyte proliferative response to phytohaemaglutynin (PHA) and allogenic lymphocytes (in mixed lymphocyte reaction--MLR), the effect of women's sera on MLR, neutrophil chemiluminescence and anticardiolipin (ACA) as well as antinuclear (ANA) antibodies titers. We found that in nonpregnant RSA women the CD8+ lymphocytes percentage was lower (20.2% vs. 23.9%) and the CD4+/CD8+ ratio higher (2.37 vs. 1.9) as compared to the controls. In comparison with normal multigravidas in recurrent aborters an absence of serum factors suppressing MLR (blocking antibodies) and a high incidence of autoantibodies was observed (ACA: 53.8% vs. 9.1%; ANA: 42.7% vs. 6.8%). The pregnancy success ratio was significantly lower for alloimmunized women with medium/high titers of ACA than for those without ACA (64% vs. 96%, p < 0.001). It was proved there were no significant differences in the estimated immunological parameters between groups of women suffering from either primary or secondary abortions. It was also shown that there is an equally high efficiency of paternal lymphocyte immunization in preventing future abortions both in primary (88%) and secondary (86%) aborters. In conclusion it can be assumed that considering the immunological conditions of nonpregnant women with recurrent spontaneous abortion of unexplained etiology differ from healthy and fertile women. These differences are mainly connected to the humoral immunity and manifested in absence of blocking antibodies in sera of women with RSA and in frequent occurrence of antinuclear and anticardiolipin antibodies. Among autoantibodies, only ACA at medium and high levels are the ones that can negatively influence on the pregnancy outcome in women with RSA who underwent paternal lymphocytes immunization. The clinical classification of women with RSA into primary and the secondary aborters is reflected neither in immunological results nor in efficacy of paternal lymphocytes immunization.

Abstract
Contents of Al, Fe, Zn, Cu, Cd, Mn, Ni, and Hg were determined in 14 species of psyllids and in leaves of their host plants from unpolluted sites (Finland) and industrially polluted sites in Poland. Generally, psyllids accumulated low amounts of metals, but their metal burdens increased with age. Exuvia were important for the elimination of Al, Ni, and Mn, and larval wax for Al, Cu, and Ni. Biomagnification of metals, expressed as the concentration factor (cf) was low (cf: 0.56-1.08) for Mn, Al, and Ni, but high for Cd (cf: 5.86). Trioza chenopodii, Cacopsylla ulmi, and Psylla betulae represented the microconcentrators (cf: 0.9-1.25); the remaining species were the macroconcentrators (cf: 2.0-4.9). In polluted areas Psyllopsis fraxini eliminated large amounts of Al, Fe, Cu, Mn, and Cd with honeydew. This way of metal elimination was of less importance in species from unpolluted sites. Adults of Cacopsylla mali, P. fraxini, P. betulae, and Cacopsylla sorbi fall a prey to ants and may be important in transfer of Zn, Fe, Cu, Cd, and Ni. In comparison with aphids their role in metal transfer is marginal, due to better self-defence mechanisms and higher mobility, which protect them from potential predators and parasites.

Abstract
Encapsulation of an OKT3 cell line in hollow fibers was evaluated in vitro and in vivo. The cell line is a mouse hybridoma producing immunoglobulin G2a (IgG2a) against CD3 human T lymphocytes and thus may function as a nonspecific activation system of a subpopulation of human T lymphocytes. For encapsulation purpose, hollow fibers of polypropylene K600 PP Accurel (Akzo, Germany) were selected. Hollow fibers were siliconized to improve membrane biocompatibility for in vivo experiments. The siliconized hollow fibers exhibited acceptable diffusive permeability (P) [ml/min/m2] for small solutes (for creatinine, p = 63.9 +/- 2.0, n = 3) and larger solutes (for albumin, p = 16.9 +/- 1.9, n = 3; for IgG, p = 1.0 +/- 0.2, n = 3). The 12 cm long hollow fibers were filled with a suspension of OKT3 cells of an average density of 10(6) cells/ ml, and both ends were sealed. The encapsulated cells were cultivated in RPMI 1640/10% CS medium at 37 degrees C, 5% CO2 for a period of 3 to 4 days. After the culture period, the medium was tested on human peripheral blood lymphocytes for the presence of anti-CD3 antibody and read in a flow FACS-trac cytometer (Becton Dickinson Immunocytochemistry Systems, San Diego, CA). The tightness of hollow fiber sealing was tested with a bubble point method. The number of cells increased after cultivation by four- to nine-fold on average (n = 11). Ten experiments were performed in vivo with OKT3 cells encapsulated in hollow fibers and implanted subcutaneously into mice for 3 days. In 50% of the experiments, some anti-CD3 antigens on human lymphocytes were found; however, the difference, in comparison with control, in percent of CD3+ was insignificant. In conclusion, the hollow fiber method for cultivation of hybridoma cells in vitro allows for separation of cells from the medium containing secreted anti-CD3 antibodies and is effective in maintaining cell viability. In vivo application needs additional study.
