Abstract
Lung cancer represents the most common type of human malignancy and is the main cause of cancer-associated mortality worldwide. To improve the effectiveness of treatment strategies, a better understanding of the mechanisms of cancer progression and invasiveness is required. Recently, B-cell activating factor (BAFF) and a proliferation-inducing ligand (APRIL), two relatively newly described cytokines belonging to the tumor necrosis factor superfamily, have been shown to play a role in cancer progression. However, at present, the effects of both cytokines on lung cancer cells remain unclear. The present study aimed therefore to understand the direct effects of BAFF and APRIL on non-small cell lung cancer (NSCLC) progression. To do so, reverse transcription quantitative PCR and western blotting were used to evaluate whether A549 and H2030 NSCLC cells express receptors for both BAFF and APRIL. The results demonstrated that both investigated cell lines expressed BAFF-R (receptor specific to BAFF only) and transmembrane activator and CAML interactor (TACI; shared receptor for both cytokines). In addition, functional experiments were performed to determine the effects of BAFF and APRIL stimulation on cancer cell viability. The results demonstrated no direct effects of BAFF and APRIL on NSCLC cell proliferation and invasiveness. In summary, the present study demonstrated that NSCLC cells possess the ability to respond directly to both BAFF and APRIL. However, activation of BAFF-R and TACI signaling in cancer cells did not increase the proliferative capacity and invasiveness. Further investigation is thus required to better understand the role of BAFF and APRIL on the progression of NSCLC.

Abstract
BACKGROUND Ultrasound elastography is a noninvasive method of imaging based on the estimation of the mechanical properties of tissue. Data in adults indicate that decreased flexibility in comparison to the surrounding healthy tissue is characteristic of malignancy (in most thyroid carcinomas, except for follicular thyroid carcinoma). The purpose of our study was to assess the deformation of thyroid nodules and to evaluate the usefulness of elastography in predicting malignant thyroid nodules in adolescent patients. METHODS We examined 47 children with 62 thyroid nodules. All patients underwent elastography and fine needle aspiration cytology (FNAC). RESULTS Thirty-seven girls (79%) and 10 boys (21%) were included in the study. A strain ratio <2 was observed in 17 nodules (27% of the study group), a strain ratio between 2 and 4.9 in 34 nodules (55%) and a strain ratio >5 in 11 nodules (18%). According to cytological examination, 3 nodules (4.8% of the study group) were malignant. Two of them were hard (strain ratio ≥5), and 1 nodule had a strain ratio of 2. CONCLUSIONS Our results suggest that elastography can be complementary to conventional ultrasonography and useful while making a decision about FNAC. At the same time, it should not replace the cytological assessment of thyroid nodules in children and adolescents.

Abstract
INTRODUCTION We showed previously that the prothrombotic effect of one hour aldosterone (ALDO) infusion in rats was only partially mediated by the mineralocorticoid receptor (MR). Bearing in mind that ALDO potentiates the effects of angiotensin II (Ang II), in the present study we investigated the role of Ang II receptor type 1 - AT1 in acute ALDO prothrombotic action. MATERIALS AND METHODS The experiments were performed in a stasis-induced venous thrombosis model in male Wistar, normotensive rats. ALDO (30μg/kg) was infused for 1h. Valsartan (VAL; 10mg/kg), a selective AT1 receptor antagonist, was administered in a single bolus injection before ALDO infusion. Eplerenone (EPL, 100mg/kg), a selective MR receptor antagonist, was administered per os before ALDO. Thrombus weight and incidences of thrombosis were assayed. Bleeding time and platelet adhesion to collagen were evaluated as primary hemostasis parameters. The plasma levels of some coagulation and fibrinolysis parameters, and plasma NO metabolite levels were assayed. RESULTS AT1 blockade with valsartan significantly reduced ALDO-induced thrombosis expressed as a reduced thrombus mass (p<0.05 vs ALDO) and diminished the incidence of thrombosis. Valsartan reduced the ALDO-induced changes in bleeding time and platelet adhesion, as well as in coagulation, fibrinolysis, and NO metabolite levels. The effect of AT1 blockade in ALDO-induced thrombosis was similar to the effect of MR blockade. However, dual blockade of AT1 and MR showed no additional benefit. CONCLUSIONS ALDO prothrombotic action is partially mediated via AT1 receptor in the mechanism involving enhanced platelet activation, induced coagulation, impaired fibrinolysis and reduced NO bioavailability.

Abstract
Tumour necrosis factor-alfa (TNF-α) is an inflammatory cytokine with a wide spectrum of biological activity, including angiogenesis. Tumour necrosis factor-related apoptosis inducing ligand (TRAIL), which belongs to the TNF family of proteins, plays a role in the regulation of vascular responses, but its effect on the formation of new blood vessels (angiogenesis) is unclear. We analysed TRAIL concentrations in parallel with pro-angiogenic cytokines in serum and their expression in trephine biopsy (TB) in 56 patients with newly diagnosed IgG MM and 24 healthy volunteers. The study showed statistically higher concentrations of TRAIL and TNF-α, as well as of VEGF and its receptor, in MM patients compared to healthy volunteers and patients in advanced stages of the disease. Furthermore, we observed a significant decrease in all studied pro-angiogenic cytokines and significant increase of TRAIL concentration after anti-angiogenic therapy, with meaningful differences between responders (at least partial remission) and patients with progression during the induction treatment. It was also established that TRAIL correlated statistically and negatively with pro-angiogenic cytokines such as VEGF with its receptor and expression of VEGF and syndecan-1 in TB. In summary, our data indicate that in MM patients, both clinical course and treatment responsiveness are associated with dynamic yet corresponding changes of levels of TRAIL parallel pro-angiogenic mediators such as VEGF with its receptor and expression of VEGF and syndecan-1 in TB.

Abstract
B cell-activating factor (BAFF), a proliferation-inducing ligand (APRIL) and apoptosis-inducing ligand (TRAIL) were demonstrated in several haematological diseases including acute myeloid leukemia (AML). Those cytokines are capable of activating a broad spectrum of intracellular signalling cascades that can either induce apoptosis or protect from programmed cell death. We have analysed BAFF, APRIL and TRAIL serum concentrations in 76 patients with newly diagnosed AML and 40 healthy volunteers. The values were significantly higher for APRIL and BAFF but lower for TRAIL compared to healthy volunteers. Induction therapy significantly reduced the values for BAFF and increased them for TRAIL. Moreover, the concentration of BAFF and APRIL was significantly lower and the concentration of TRAIL higher in a group of patients with complete remission compared to non-respondent AML patients. In addition, higher concentrations of BAFF and lower of TRAIL predicted a shorter overall survival, suggesting thereby an important prognostic marker and possible therapeutic target in AML.

Abstract
BACKGROUND Tumor growth in multiple myeloma (MM) is regulated by the cytokine networks which are produced by myeloma cells and the microenvironment of the bone marrow. Interleukin-17 (IL-17) is implicated in the increased angiogenesis in the bone marrow of MM. Recent studies reported elevated levels of interleukin 17A (IL-17A) in the sera of patients with advanced stages according to Durie-Salmon classification. MATERIAL/METHODS We compared the concentration of IL-17A and IL-17E in the blood serum of 34 newly diagnosed MM patients with healthy subjects' sera. We also evaluated the concentration of IL-17A and IL-17E in the blood serum of MM patients and the relation to the percentage of plasma cells and other clinical parameters. The concentration of IL-17E and IL-17A of healthy subjects and patients with MM was assessed by enzyme-linked immunosorbent assay (ELISA). RESULTS Our data confirm that IL-17A and IL-17E serum levels were significantly higher in all MM patients and also in patients with advanced stage compared with healthy subjects. We found the correlation between serum levels of IL-17A in MM patients and percentage of plasma cells. Our results also showed that if serum levels of IL-17E were higher in MM patients, the percentage of plasma cells and beta-2-microglobulin levels were lower. CONCLUSIONS The IL-17 family of cytokines may suppress or promote tumor growth. There seems to be some balance between the effects of IL-17A and IL-17E. The role of increased levels of IL-17E needs further investigation to understand its role in the pathobiology of MM.

Abstract
A twenty eight-year-old male presented with a two week history of dyspnea, cough, hemoptysis, chest pain, and fever 38-39°C. He also complained of loss of appetite, general weakness and left leg pain for two months preceding admission. He was referred with suspicion of lung tumor to our institution. Chest X-ray showed almost total atelectasis of the right lung with compensatory overinflation of the contralateral lung. Using computed tomography (CT), a lesion of diameter of 19.3 x 14.1 x 19.1 cm in the right lung, pleuritis, Th3 osteolysis, and compensatory overinflation of the left lung was seen. Bronchoscopy revealed a total obstruction of the right main bronchus due to submucosal infiltration and compression of the right main bronchus with negative histology of bronchial biopsy specimens. Transthoracic fine needle aspiration revealed celullae suspectae probabiliter neoplasmaticae suggesting tumor fusocellularis. USG of the abdomen revealed liver with numerous heterogeneous, solid areas hypo- and hyperechogenic, some of them with features of liquid or the disintegration up to diameter of 74 mm. Subsequent fine needle aspirations of the thorax and liver revealed fibrolamellar hepatocarcinoma and carcinoma adenoides of the lung. Patient underwent chemotherapy with 5-FU/DDP/VCR with no response. This report presents a case of a rare lung metastasis from FL-HCC.

Abstract
BACKGROUND Cannabinoid receptors CB1 and CB2 are part the endocannabinoid system that plays an important role in the process of proliferation and apoptosis of different neoplastic cells. B-cell chronic lymphocytic leukaemia is one of the diseases in which these processes are altered. AIM The aim of our study was the assessment of cannabinoid receptor expression on the B-lymphocytes in bone marrow trephine biopsy from leukaemic patients at diagnosis and after purine analogue treatment. METHODS The biopsy was taken routinely and standard immunohistochemical staining procedure for paraffin embedded sections was applied. The cannabinoid receptors were detected using specific primary polyclonal antibody anti-CB1 and anti-CB2. Additionally, an existence of cannabinoid receptors was confirmed by flow cytometry. RESULTS The results showed that the expression of CB1 receptor on the surface of neoplastic cells was lower than that of CB2 (17.0+/-3.1% and 92.1+/-1.7% respectively, p<0.001). Nine of the patients responded to applied treatment with a reduction in leukaemic infiltration (77.2+/-6.9% to 30.2+/-6.5%, p=0.007) and CB1 receptor expression (24.4+/-4.8% to 8.6+/-2.9%, p=0.01), but there was no change in CB2 expression (91.7+/-2.7% vs 90.9+/-2.8%, p=0.69). Four patients without remission expressed even greater number of the receptors. In all of the cases both cannabinoid receptor types antibodies gave positive reaction. Furthermore, the existence of cannabinoid receptors on neoplastic lymphocytes was confirmed by flow cytometry. CONCLUSION The study provides original evidence for the existence of cannabinoid receptors on B-lymphocytes in chronic lymphocytic leukaemia patients. The receptors are thought to be a new structure that can modify the course of the disease and may be considered as a new target in leukaemia treatment.

Abstract
AIM: To analyze the protein expression essential for apoptosis in liver steatosis.
METHODS: The expression of proapoptotic proteins p53, Bax, and antiapoptotic Bcl-2 in hepatocytes with steatosis (SH) and without steatosis (NSH) was evaluated in 84 patients at various stages of non-alcoholic fatty liver disease (NAFLD).
RESULTS: Immunohistochemical staining of liver tissue showed the activation of p53 protein in SH and NSH with increased liver steatosis, diminished Bcl-2 and slightly decreased Bax protein. Positive correlation was found between the stage of liver steatosis with p53 expression in SH (r = 0.54, P < 0.01) and NSH (r = 0.49, P < 0.01). The antiapoptotic protein Bcl-2 was diminished together with the advancement of liver steatosis, especially in non-steatosed hepatocytes (r =0.43, P < 001).
CONCLUSION: Apoptosis is one of the most important mechanisms leading to hepatocyte elimination in NAFLD. The intensification of inflammation in NAFLD induces proapoptotic protein p53 with the inhibition of antiapoptotic Bcl-2.

Abstract
BACKGROUND/AIMS Gene p53 plays an important role in apoptosis or regeneration of damaged tissues. HCV activates gene p53 directly and/or indirectly. In chronic hepatitis, hepatocyte regeneration is regulated by gene p53 and growth factors. The aim of the study was the evaluation of protein p53 expression on hepatocytes in chronic hepatitis C regarding inflammatory activity and fibrosis as well as the influence of interferon alpha 2b (IFNalpha2b) on gene p53 activity. METHODOLOGY In 24 patients with chronic hepatitis C treated with IFNalpha2b (18MU sc/week/48 weeks), in whom liver biopsies were performed before and after IFNalpha2b treatment. The immunohistochemical method determined protein p53 in formalin-fixed, paraffin-embedded liver tissue sections. The percentage of p53-positive hepatocytes and intensity of protein p53 accumulation were evaluated under a light microscope. RESULTS IFN treatment caused the increase in the percentage of p53-positive hepatocytes and the intensity of protein p53 accumulation. The highest level of protein p53 expression was observed in IFNalpha2b-treated tissues with the decrease in inflammatory activity and fibrosis. HCV infection elimination did not affect protein p53 expression. We observed the decrease in p53-positive hepatocytes in tissues without improvement of morphological regeneration during IFNalpha2b therapy. CONCLUSIONS The increase in protein p53 expression can be considered a prognostic marker of the positive effect of IFNalpha2b treatment and HCV elimination. It may result from the effect of the increase in regeneration or apoptosis of HCV infected hepatocytes.

Abstract
OBJECTIVES Nitric oxide (NO) is involved in the control of pancreatic blood flow and secretion, and its role in the maintenance of pancreatic tissue has been suggested. The aim of our study was to evaluate the influence of NO on pancreatic trophic parameters during acute pancreatitis induction and the pancreas recovery process. DESIGN/METHODS Acute pancreatitis was induced in rats by a supramaximal dose of caerulein. During acute pancreatitis induction, rats were treated with L-arginine (a substrate for NO synthesis), glyceryl trinitrate (NTG, NO donor), glycine, N(G)-nitro-L-arginine (L-NNA, NO synthase inhibitor), L-arginine + L-NNA, or saline. Pancreatic weight, total contents of RNA, DNA, protein, amylase and chymotrypsin as well as pancreas histology and the number of proliferating acinar cells were evaluated after pancreatitis induction in all groups and additionally after 7 and 14 days of recovery in untreated acute pancreatitis rats or those injected with L-NNA and/or L-arginine. RESULTS Pancreas destruction after acute pancreatitis was evidenced by similar decreases of all parameters in untreated acute pancreatitis rats or those treated with L-NNA or glycine when compared to control healthy animals. The recovery process after acute pancreatitis was not affected by L-NNA injections; however, the increased cell proliferation occurred later than in untreated rats. NTG and especially L-arginine treatment resulted in significant attenuation of pancreas damage (partially prevented by L-NNA treatment) as evidenced by biochemical data with a slight improvement in morphology. Treatment with L-arginine alone or in combination with L-NNA resulted in augmented cell proliferation after acute pancreatitis induction followed by earlier recovery in comparison to untreated acute pancreatitis rats or the L-NNA-injected group. CONCLUSION The present study suggests the involvement of NO in mild acute pancreatitis and in the recovery process after inflammatory damage.

Abstract
BACKGROUND/AIMS Fine-needle biopsy (FNB) is one of the diagnostic methods for the diagnosis of focal lesions in the liver. The method is relatively fast, inexpensive and safe. Complications after FNB are observed in only a few cases. Color Doppler sonography (CDS) is one way of minimizing the number of FNB complications. The aim of the present study is to evaluate CDS in the monitoring of FNB in the diagnosis of focal lesions in the liver. METHODOLOGY The patient group consisted of 73 patients: 28 male and 45 female with a mean age of 53.5 years. Initially, all patients were examined using traditional B-mode gray-scale sonography. After visualization of focal lesions in the liver their echostructure and position were analyzed. Color Doppler sonography was the introduced for the visualization of vascularization of the liver. FNB was performed under the guidance of CDS. The cytological specimens obtained were microscopically evaluated. RESULTS Of the 73 patients, 18 cases were diagnosed with liver abscess, 19 with cysts of the liver, and 36 with malignant tumors. Amongst the patients with malignancy tumors, the tumors were unifocal in 15 cases, and multifocal in 221. Histopathologically, there were primary hepatocellular carcinomas in 22 patients and metastatic tumors in 14 patients. During the first 48 hours after FNB no complications such as subcapsular hematoma or intraperitoneal bleeding were observed. CONCLUSIONS Introducing CDS for ultrasound guided percutaneous FNB of the liver avoids such complications as bleeding, especially in patients with a high risk of hemorrhage.

Abstract
The course of radiculopathy is sometimes associated with weakness and wasting of muscles. Very rarely in such cases, however, is hypertrophy of muscle fibres observed. Three cases are presented of sciatica with enlarged calves caused by hypertrophy of type 1 or types 1 and 2 muscle fibres. In light of the literature and the results obtained, an attempt is made to explain the cause of rare clinical symptoms and draw attention to diagnostic and therapeutic difficulties.

Abstract
The cases of polycystic disease of kidney selected from 33 years postmortem data were presented. They were classified into 4 types (according to Osathanond, Potter and Heptinstall) and the results correlated with accompanying malformations. It has been established that type I of polycystic disease of kidney was mostly correlated with CNS, skull and spine abnormalities. Type II and III were coexisting with genitourinary and ++gastrointestinal system malformations. No type IV of the disease has been found.
