Abstract
Cancer and ionizing radiation exposure are associated with inflammation. To identify a set of radiation-specific signatures of inflammation-associated genes in the blood of partially exposed radiotherapy patients, differential expression of 249 inflammatory genes was analyzed in blood samples from cancer patients and healthy individuals. The gene expression analysis on a cohort of 63 cancer patients (endometrial, head and neck, and prostate cancer) before and during radiotherapy (24 h, 48 h, ~1 week, ~4-8 weeks, and 1 month after the last fraction) identified 31 genes and 15 up- and 16 down-regulated genes. Transcription variability under normal conditions was determined using blood drawn on three separate occasions from four healthy donors. No difference in inflammatory expression between healthy donors and cancer patients could be detected prior to radiotherapy. Remarkably, repeated sampling of healthy donors revealed an individual endogenous inflammatory signature. Next, the potential confounding effect of concomitant inflammation was studied in the blood of seven healthy donors taken before and 24 h after a flu vaccine or ex vivo LPS (lipopolysaccharide) treatment; flu vaccination was not detected at the transcriptional level and LPS did not have any effect on the radiation-induced signature identified. Finally, we identified a radiation-specific signature of 31 genes in the blood of radiotherapy patients that were common for all cancers, regardless of the immune status of patients. Confirmation via MQRT-PCR was obtained for BCL6, MYD88, MYC, IL7, CCR4 and CCR7. This study offers the foundation for future research on biomarkers of radiation exposure, radiation sensitivity, and radiation toxicity for personalized radiotherapy treatment.

Abstract
The validity of the Brink-Axel hypothesis, which is especially important for numerous astrophysical calculations, is addressed for ^{116,120,124}Sn below the neutron separation energy by means of three independent experimental methods. The γ-ray strength functions (GSFs) extracted from primary γ-decay spectra following charged-particle reactions with the Oslo method and with the shape method demonstrate excellent agreement with those deduced from forward-angle inelastic proton scattering at relativistic beam energies. In addition, the GSFs are shown to be independent of excitation energies and spins of the initial and final states. The results provide a critical test of the generalized Brink-Axel hypothesis in heavy nuclei, demonstrating its applicability in the energy region of the pygmy dipole resonance.

Abstract
The purpose of the study was to identify the psychological peculiarities of patients with disorders of the musculoskeletal system in order to identify in the future the targets of medical and psychological intervention, correction and complex treatment of this contingent. The study methods: Inventory form SF-36 - short form of the nonspecific Inventory for determination of a life quality (The 36-Item Short Form Health Survey, Coping Inventory for Stressful Situations, CISS), S. Norman, D. F. Endler, D. A. James, M. I. Parker, adopted by T. L. Kryukova, A. Buss and A. Durkee Hostility Inventory, BDHI, adopted by A. L. Osnitsky), Test of self-assessment of stress resistance of S. Kouhen and G. Willianson The study showed a significant difference (p<0,05) in the quality of life of the examined main group and comparison group. In the course of the study it was confirmed that the significant reasons for the decrease in the quality of life of the patient are age-related, individual-psychological differences and social ones. Correlation analysis revealed the relationship of aggression with indicators of the quality of life of the subjects, a direct relationship between indicators of "physical health" and "physical functioning" and between indicators of "pain" and "physical functioning", an inverse relationship between indicators of stress resistance and "physical health". Identification of the targets of medical and psychological correction will make it possible to develop a program of prevention, rehabilitation of people of mature age with with disorders of the musculoskeletal system, taking into account the factors of influence and the involvement of relevant specialists while maintaining an individual approach.

Abstract
BACKGROUND This work summarizes our experience with WT1 monitoring before and after allogeneic hematopoietic stem cell transplantation (allo-HSCT). PATIENTS AND METHODS The expression of WT1 gene was measured by real-time polymerase chain reaction in peripheral blood according to the European Leukemia Net recommendations. Between May 2005 and August 2019, we analyzed 147 consecutive patients with acute myeloid leukemia with high WT1 expression at diagnosis, transplanted in first (CR1) or second (CR2) complete remission. RESULTS At the time of allo-HSCT, 107 patients had WT1-normal expression (WT1 ≤ 50 copies), and 40 patients had WT1-high expression. The median follow-up was 21 months. The estimated 5-year overall survival and event-free survival was significantly better in the WT1-normal cohort (65% and 57% vs. 37% and 25%; P = .0003 and P < .0001, respectively) and 5-year cumulative incidence of relapse was significantly lower in the WT1-normal group (19% vs. 53%; P < .0001). Five-year non-relapse mortality was not significantly different (20% and 23%). Multivariate analysis revealed WT1-high expression and acute graft-versus-host disease grade 3/4 as significantly negative prognostic factors for OS. Overall, 49 patients developed WT1 molecular relapse in the post-transplant period; in 14 cases, the therapeutic intervention was done. In all but 1 relapsed patient where WT1 minimal residual disease (MRD) was monitored (38 patients), we detected WT1-high levels (sensitivity of 97%). CONCLUSION The results of the analysis confirmed our previous experience that WT1 status before allo-HSCT is a strong prognostic factor for both OS and relapse risk. In addition, we confirmed the usefulness of this marker for MRD monitoring after allo-HSCT. The main advantage is the possibility of frequent MRD monitoring in peripheral blood and early bone marrow examination based on WT1-high expression.

Abstract
Atopy is excessive production of IgE in response to allergens. We evaluated in patients undergoing allogeneic hematopoietic cell transplantation (HCT) the following hypotheses: (1) Atopy is "curable" in atopic patients receiving HCT from a nonatopic donor (D-R+), and (2) Atopy is transferable from atopic donors to nonatopic recipients (D+R-). Atopic patients with atopic donors (D+R+) and non-atopic patients with non-atopic donors (D-R-) served as controls. We measured levels of multiallergen-specific IgE (A-IgE, atopy defined as ≥0.35 kUA/L) in sera from 54 patients and their donors pre HCT and from the patients at ≥2 years post HCT. Only 7/12 (58%) D- R+ patients became nonatopic after HCT. Only 1/11 (9%) D+R- patients became atopic. Eleven of 13 (85%) D-R- patients remained nonatopic. Unexpectedly, 11/18 (61%) D+R+ patients became nonatopic. In conclusion, contrary to our hypothesis and previous reports, the "cure" of atopy may occur in only some D-R+ patients and the transfer of atopy may occur rarely. The "cure" may not be necessarily due to the exchange of atopic for nonatopic immune system, as the "cure" may also occur in D+R+ patients.

Abstract
IntroductionThe current situation in Ukraine is characterized by multitude social-stress factors, resulting in an increase in alcohol consumption and alcohol addiction, which arises as a mechanism to compensate the adverse mental stress and different variant of chronic stress disorder.ObjectiveSubstantiate the neurobiological basis of mutual influence of stress burden and alcohol addiction.AimTo study the biochemical mechanisms that underlie the vicious circle of stress and alcohol addiction.MethodsStudies the features of hypothalamic-pituitary-adrenal (HPA) axis under stress and alcohol available in Medline, Institute for Scientific Information Databases (Science citation index expanded and Social sciences citation index), EMBASE, and Cochrane Library were identified and reviewed.ResultsAlcohol, just like stress, affects the HPA axis, changing the reaction of its parts and, by reducing the production of cortisol, which produces in response to stress and prolongs subjective experiences of nervous tension caused by stress. Stress, through the output of cortisol, reduces the effect of alcohol leads to a desire to further alcohol abuse. The system includes elements of the extended amygdala, which have as reinforcement and stress reactivity. Central nucleus amygdala plays a leading role in the reinforcing effects of pharmacological agents with narcogene potential and performs persuasive role in the activation of hypothalamic reinforcement mechanisms. This allows us to consider neurohormonal system, including the amygdala, hypothalamus, pituitary and adrenal glands as structural and functional basis of formation depending on various narcogene, primarily alcohol.ConclusionsDysregulation of the HPA axis is a neurobiological basis of mutual influence of stress burden and alcohol addiction.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Abstract
BACKGROUND Atopy is defined as excess allergen-specific IgE (A-IgE). IgE is produced by plasma cells that differentiate from allergen-specific B cells. B cells are known to be killed by chemotherapy; however, it is not known whether A-IgE-secreting plasma cells are killed or inhibited by chemotherapy. If yes, serum A-IgE levels would be expected to decrease after chemotherapy. OBJECTIVES We aimed to determine whether A-IgE levels in atopic individuals (serum A-IgE ≥0.35 kUA/L) decrease into the nonatopic range (< 0.35 kUA/L) after chemotherapy. METHODS In 105 patients undergoing chemotherapy for acute leukemia, we measured serum A-IgE before and after chemotherapy. In a subset of these patients, we also measured B cell counts before and after chemotherapy. RESULTS Of the 105 patients, 36 were atopic. In these patients, median A-IgE level before chemotherapy was 1.6 kUA/L whereas the median level after chemotherapy was 0.6 kUA/L (p < 0.001). In 12/36 (33%) patients, A-IgE levels decreased into the nonatopic range. In nonatopic patients (n = 69), the median A-IgE level also dropped: from 0.04 kUA/L before to 0.03 kUA/L after chemotherapy (p = 0.001). Among the total patients (n = 105), the median pre:post-chemotherapy A-IgE ratio was 1.8 (2.6 in atopic and 1.5 in nonatopic patients). In contrast, the median ratio of pre:post-chemotherapy B cell counts was 87.6. CONCLUSIONS A-IgE levels decrease after chemotherapy but markedly less than B cell counts. Thus, at least some A-IgE plasma cells appear to survive chemotherapy.

Abstract
Cartilage fatigue may be a factor in the precocious development of degenerative changes in the temporomandibular joint (TMJ). This cross-sectional study estimated potential for cartilage fatigue via TMJ energy densities (ED) and jaw muscle duty factors (DF), which were combined to calculate mechanobehavioral scores (MBS) in women with (+) and without (-) bilateral TMJ disc displacement (DD). All subjects gave informed consent to participate and were examined using Diagnostic Criteria (DC) for Temporomandibular Disorders (TMD) and magnetic resonance (MR) and computed tomography (CT) images. Forty-seven subjects were categorized into +DD ( n = 29) and -DD ( n = 18) groups. Dynamic stereometry (MR images combined with jaw-tracking data) characterized individual-specific data of TMJ stress-field mechanics to determine ED (ED = W/ Q mJ/mm3, where W = work done, Q = volume of cartilage) during 10 symmetrical jaw-closing cycles with a 20-N mandibular right canine load. Subjects were trained to record masseter and temporalis electromyography over 3 days and 3 nights. Root mean square electromyography/bite-force calibrations determined subject-specific masseter and temporalis muscle activities per 20-N bite-force (T20 N, µV), which defined thresholds. Muscle DF (DF = % duration of muscle activity/total recording time) were determined for a range of thresholds, and MBS (ED2 × DF) were calculated. Intergroup differences in ED, DF, and MBS were assessed via analyses of variance with Bonferroni and Tukey honest significant difference post hoc tests. Average ED for contralateral TMJs was significantly larger ( P = 0.012) by 1.4-fold in +DD compared to -DD subjects. Average DF were significantly larger (all P < 0.01) for +DD compared to -DD subjects by 1.7-, 2.5-, and 1.9-fold for day, night, and overall, respectively. Daytime MBS were significantly larger (all P < 0.04) by up to 8.5-fold in +DD compared to -DD subjects. Significantly larger ED, DF, and MBS were shown in women with compared to women without bilateral TMJ DD.

Abstract
OBJECTIVE Cartilage fatigue, due to mechanical work, may account for the early development of degenerative joint disease (DJD) in the temporomandibular joint (TMJ), and why women are three times more likely to be afflicted. This study tested for gender differences in mechanical energy densities in women and men with healthy TMJs. DESIGN Eighteen women and eighteen men gave informed consent. Research diagnostic criteria including imaging were used to ensure that subjects' TMJs were normal, without disc displacement or signs of DJD. Numerical modeling determined TMJ loads (Fnormal). Jaw tracking and three-dimensional dynamic stereometry characterized individual-specific data of stress-field dynamic mechanics during 10 symmetrical jaw closing cycles. These data were used to estimate tractional forces (Ftraction). Energy densities were then calculated, where: Energy Density = W/Q (W = work done or mechanical energy input = Ftraction*distance of stress-field translation, Q = volume of cartilage). Two-way analysis of variance (ANOVA) and follow-up two-group comparisons tested mean energy densities for ipsilateral and contralateral TMJs in women vs men. RESULTS Mean energy densities ± standard deviations in ipsilateral and contralateral TMJs in women were 9.0 ± 9.7 and 8.4 ± 5.5 mJ/mm3, respectively, and were significantly larger (P = 0.004 and 0.001, respectively) compared to ipsilateral and contralateral TMJs in men, which were 5.6 ± 4.2 and 6.3 ± 4.2 mJ/mm3, respectively. CONCLUSIONS Energy densities were significantly larger in healthy TMJs of women than men. Larger TMJ energy densities during normal jaw functions could predispose earlier mechanical fatigue of the TMJ disc.

Abstract
This study was aimed at elucidating the fate of three important nuclear envelope components - lamins B and A/C and nucleoporin Nup160, during meiotic maturation of mouse oocytes. These proteins were localized by epifluorescence and confocal microscopy using specific antibodies in oocytes at different stages from prophase I (germinal vesicle) to metaphase II. In immature germinal vesicle oocytes, all three proteins were detected at the nuclear periphery. In metaphase I and metaphase II, lamin B co-localized with the meiotic spindle, lamin A/C was found in a diffuse halo surrounding the spindle and to a lesser degree throughout the cytoplasm, and Nup160 was concentrated to the spindle poles. To our knowledge, this is the first report on nucleoporin localization in mammalian oocytes and the first successful detection of lamins in mature oocytes. While the distribution patterns of both lamins closely paralleled the respective stages of mitosis, Nup160 localization in metaphase oocytes corresponded to that in mitotic prometaphase rather than metaphase. The peculiar distribution of this nucleoporin in oocytes may reflect its role in meiosis-specific mechanisms of spindle assembly and its regulation.

Abstract
Overexpressed Wilms tumor gene 1 (WT1) has been found in a majority of patients with acute myeloid leukemia (AML). The aim of this study was to confirm the applicability of WT1 expression measurement as a marker of minimal residual disease (MRD). The expression of WT1 gene was measured by real-time polymerase chain reaction in peripheral blood (PB) according to European Leukemia Net (ELN) recommendations. The WT1 expression was related to the expression of a reference gene Abelson (ABL) and the results were calculated as a number of WT1 copies related to 104 copies of ABL gene. The upper normal limit of WT1 expression was set at 50 copies of WT1 to 104 copies of ABL. Morphological, flow cytometry and chimerism examinations were evaluated according to standard protocols.A total of 51 AML patients with overexpressed WT1 gene were analyzed. The median follow-up after transplantation was 14 (2-72) months. WT1 expression levels exceeding the upper normal limit were considered as a sign of impending hematological relapse, in accord with morphological, flow cytometry and chimerism data, as well as with the expression of the specific fusion genes. Moreover, in 7 patients the rise of WT1 expression preceded all other standard methods. Patients with high WT1 expression before allogeneic hematopoietic stem cell transplantation (allo-HSCT) had significantly worse outcome than patients with low WT1 level. Examination of WT1 expression in PB of patients with AML is a useful tool for MRD monitoring. Moreover, the WT1 gene expression before stem cell transplantation seems to be of prognostic significance.

Abstract
Despite of the importance of cytoskeletal proteins for ovarian function and pathology, very few studies have addressed the presence and distribution of these proteins in polycystic ovaries. We investigated sections of human polycystic ovarian tissue for vimentin and a set of cytokeratins by epifluorescence. The studied proteins showed strong colocalization. Positive reaction was detected in two main ovarian compartments: with weak intensity in follicular cells and very strong in perinuclear position in oocytes of primordial follicles. Epifluorescent study of the oocytes from primordial follicles allowed us to identify the immunopositive structure in oocytes as Balbiani body, a transient organelle responsible for establishing oocyte polarity and ooplasm gradients in nonmammalian vertebrates. Our results suggest functional interaction of different types of cytoplasmic intermediate filament proteins in polycystic ovaries and a possible importance of the Balbiani body for human oogenesis in norm and pathology.

Abstract
This review summarizes conventional and recent applications of genomic in situ hybridization (GISH). GISH is a well recognized technique, but its modifications and applications have not been widely used. Here, we show how modifications to the GISH technique can be used as tools to 'paint' plant chromosomes. In addition, we describe novel applications, e.g. how GISH banding could be used for karyotyping plant chromosomes. We further discuss recent phylogenetic applications of GISH that allow a semiquantitative signal analysis and the possibility of comparing and combining this cytogenetic technique with DNA sequence-based phylogenetic trees.

Abstract
Dasatinib is effective second line treatment for patients with chronic myeloid leukemia (CML) resistant or intolerant to imatinib. We report here the first experiences with dasatinib therapy in 71 CML patients resistant or intolerant to imatinib from the real clinical practice of 6 hematological centers in the Czech Republic. Dose 100 mg daily and 70 mg twice daily was administered to patients with chronic phase (CP) and advanced phases (AP) CML. In chronic phase (n=46), complete hematological reponse (CHR) was achieved in 97%, major cytogenetic reponse (MCgR) in 77% and complete cytogenetic response (CCgR) in 67%. Major molecular reponse (MMR) was achieved in 19/31 patients in median of 10 months. In advanced phase (n=25), CHR was attained in 77%, MCgR in 39%, CCgR in 33% and MMR in 2/18 patients. Eleven different baseline mutations were followed up in 15 patients. Dasatinib eliminated mutations in most of the patients, but 3 patients acquired a new one. Novel mutations were detected under dasatinib therapy in 2 patients. Dasatinib was well tolerated, cytopenias were common and was managed by dose modification. The estimated progression free survival (PFS) at 12 months was 97+/-3% in CP and 62+/-21% in AP. The median time to treatment failure was 605 days in AP while it was not reached in CP patients. Our clinical experiences, described here, confirmed that dasatinib is associated with high response rates especially in imatinib resistant or intolerant CML patients in chronic phase.

Abstract
Introduction Procalcitonin (PCT) and C-reactive protein (CRP) are established markers of infection in the general population. In contrast, several studies reported falsely increased PCT levels in patients receiving T-cell antibodies. We evaluated the validity of these markers in patients scheduled for hemopoietic stem cell transplantation receiving anti-thymocyte globulin (ATG) during conditioning. We also assessed renal and liver functions and their relationship to PCT and CRP changes. Methods Twenty-six patients without clinical signs of infection were prospectively studied. ATG was administered in up to three doses over the course of 5 days. PCT, CRP, white blood cell (WBC) count, urea, creatinine, glomerular filtration rate, bilirubin, alanin amino-transferase (ALT), and gamma-glutamyl transferase (GGT) were assessed daily during ATG administration. Pharyngeal, nose, and rectal swabs and urine samples were cultured twice weekly. Blood cultures were obtained if clinical symptoms of infection were present. Results Baseline (BL) levels of both PCT and CRP before ATG administration were normal. WBC count decreased after ATG administration (P = 0.005). One day after ATG administration, both PCT and CRP levels increased significantly, returning to BL levels on day 4. Microbiological results were clinically unremarkable. There was no interrelationship between PCT levels and BL markers of renal or liver functions (P > 0.05 for all comparisons). Bilirubin and GGT were increased on days 2 to 5 and ALT was increased on day 3 (P < 0.05 versus BL). No difference in renal functions was observed. Three patients developed bacterial infection on days 7 to 11 with different dynamics of PCT and CRP. There was no association between the number of ATG doses and PCT levels or between the risk of developing infection and previous PCT levels. Conclusions ATG triggered a marked early surge in PCT and CRP followed by a steady decrease over the course of 3 days. The dynamics of both PCT and CRP were similar and were not associated with infection. PCT levels were independent of renal and liver functions and were not predictive of further infectious complications. A direct effect of ATG on T lymphocytes could be the underlying mechanism. Hepatotoxic effect could be a contributing factor. Neither PCT nor CRP is a useful marker that can identify infection in patients receiving ATG.

Abstract
Two patients with the characteristic high human herpesvirus 6 (HHV-6) DNA loads in peripheral blood caused by chromosomally integrated (CI) virus received a haematopoietic stem cell transplant (HSCT) from a donor without CI HHV-6. Both patients died in consequence of cytomegalovirus (CMV) pneumonitis. At autopsy, high amounts of CMV DNA were detected in lungs but at much lower levels in other organs. In contrast HHV-6 DNA was detected at high levels throughout the organs with the exception of donor-derived haematopoietic tissue. In individuals with chromosomal integration, HHV-6 DNA is found in every tissue of recipient origin indicating inheritance through the germ line.

Abstract
Purine analogs are often used for conditioning preceding allogeneic hematopoietic stem cell transplantation (HCT). We prospectively tested fludarabine (Flu) 40 mg/m(2)/day x 5 days vs cladribine (Clad) 10 mg/m(2)/day x 5 days plus oral busulfan (1 mg/kg q6 h x 2 days) and total body irradiation 200 cGy in 32 recipients of matched sibling and unrelated donor (URD) HCT. Patients were similar in age (median 52 years), diagnosis, extensive pre-HCT therapy (56 vs 63%), and high-risk disease status (81 vs 93%). Neutrophil engraftment was prompt (median 11 vs 12 days), but early graft failure using Clad halted randomization. Platelet recovery was prompt (median Flu 18 vs Clad 24 days). Graft-versus-host disease (GVHD) after Flu vs Clad was similar; (acute grade II/IV 56 vs 69%, P=0.26; chronic 50 vs 31%, P=0.27). Nonrelapse mortality (Flu 25 vs Clad 38%, P=0.47) and progression-free survival at 3 years were similar as well. Multivariate analyses showed slightly, but not significantly lower relative risk (RR) of neutrophil engraftment with Clad (RR 0.6 (95% CI 0.2-1.3) P=0.16) and with URD RR 0.4 (0.2-1.0) P=0.04). Older patients with advanced hematologic malignancies achieve satisfactory outcomes using either of these reduced intensity conditioning regimens.

Abstract
BACKGROUND Thymic epithelial cells often form lymphoid-epithelial cell (LEC) complexes, thought to contribute both to normal T-cell differentiation and to leukemogenesis. The distribution of the nerve growth factor (NGF) and NGF immunoreactivity modulation of complex-forming thymus epithelial cells were studied in mice with experimental acute L1210 leukemia. MATERIALS AND METHODS Light and electron microscopic methods and cell separation techniques were applied. RESULTS Immunoperoxidase and immunogold labelling showed subcapsular and subseptal overexpression of NGF by epithelial cells in leukemic thymus. NGF immunopositive epithelial cells were closely associated with lymphoid cells. The increased immunoreactivity of epithelial cells correlated with LEC complex formation, including thymic nurse cell-like structures and rosettes in the external cortex. CONCLUSION These results provide new structural and immunocytochemical evidence for intimate contact between NGF-producing epithelial cells and lymphoid cells and suggest that NGF immunoreactive LEC complexes are involved in thymic microenvironmental reorganization during leukemogenesis.

Abstract
BACKGROUND AND OBJECTIVES Leptin was demonstrated to stimulate the proliferation of hematopoietic stem cells in vitro, but there is scarce information concerning serum leptin levels in patients with hematological diseases. The aim of our study was to measure serum leptin levels in patients undergoing mobilization of peripheral blood stem cells (PBSC) before autologous stem cell transplantation (ASCT). DESIGN AND METHODS Eighteen patients indicated for ASCT were included in the study. The blood samples were obtained before the initiation of mobilization chemotherapy, at the phase of maximal leukopenia and on the second day of stem cell harvest. Serum leptin levels, soluble leptin receptor, cortisol, insulin, tumor necrosis factor alpha (TNFalpha), and interleukin-1 receptor antagonist (IL-1ra) levels were measured in the withdrawn samples. RESULTS The basal values of parameters measured except for higher levels of IL-1ra in mobilized group did not differ significantly from those of a control group of healthy subjects. Serum leptin levels decreased significantly at the leukopenia phase and remained suppressed in the stem cell harvest phase (means +/- standard error means (SEM): 12.2 +/- 2.4 vs. 7.7 +/- 1.5 vs. 9.3 +/- 1.9 ng mL(-1)). No significant changes were found in soluble leptin receptor, insulin, cortisol, and TNFalpha levels throughout three measurements, while IL-1ra levels increased significantly in the SC harvest phase compared to the previous two measurements. INTERPRETATION AND CONCLUSIONS As no metabolic variations explaining suppressed leptin levels were found, this suppression could be the result either of G-CSF administration or increased leptin consumption by activated stem cells.

Abstract
The aim of the present study was to evaluate serum copper concentration changes in patients with benign cysts or carcinomas of ovary, and to compare these concentrations with the normal reference serum copper levels. Patients included in the study were as follows: benign ovarian cyst cases (n = 19), endometrial cyst cases (n = 5), ovarian carcinoma cases (n = 6), female patients with no ovarian disease (n = 161). Reference serum copper levels in apparently healthy subjects were 16.8 +/- 4.15 mumol/l (mean +/- SD). Serum copper concentration were significantly increased in ovarian carcinoma patients (22.98 +/- 3.90 mumol/l) in comparison with benign cyst patients (18.40 +/- 4.61 mumol/l) (p < 0.05), in with endometrial cyst patients (15.94 +/- 4.24 mumol/l) (p = 0.02), and in comparison with normal levels in controls (p < 0.001). Copper/zinc ratios were highest in ovarian carcinoma patients--1.68, intermediate in benign cyst patients--1.42, and lowest in endometrial cyst patients--1.08. The mechanisms underlying serum copper concentration variations in the different groups are briefly discussed with special emphasis on these in ovarian carcinoma patients.

Abstract
Diagnosis of male genital tract inflammations plays a significant role in andrology. Although genital infections are often silent they can severely impair male infertility. In seminal plasma of 100 patients were determined IgG and SigA (radial immunodiffusion) the number of peroxydase-positive cells in addition to conventional semen parameters and microbiological investigations. There was carried out quantitative determination of alpha-amylase in connection with semen liquefaction. The results showed that exact quantitation of above mentioned parameters distinguish inflammatory male adnexal affections, which is appropriate for control of anti-inflammatory treatment and facilitates the diagnosis of inflammatory process in andrology.

Abstract
Over a period of 20 months we investigated 1366 vaginal specimens from pregnant women for GBS (group B streptococci) carrier in three microscopic patterns, evaluated by Nugent score system. More frequently we isolated GBS in group I intermedia (score 4-6)--20.8%, (when Lactobacillus spp. is missing--67.4%, without or associated with other nonanaerobic microorganisms (60.5%). All isolated GBS strains showed sensitivity to ampicillin and carbenicillin. Good sensitivity was found to cefazolin (92.4%) ant to cefuroxim (94.9%). The strains showed 13.7% resistance to erythromycin and 4.1% to clindamycin.

Abstract
About 8% of our patients reveal predominantly single abnormality-state, known like monomorphic teratozoospermy, which concerns round headed spermatozoa, amorphous heads, small heads, tapering heads, decapitated spermatozoa, middlepieces and tail defects. In the light of electron-microscopy study the quality and information exactness increases significantly in comparison to conventional semen analysis. Such kind of study, however is not acquitted in normal fertile men, although the finding some of the above mentioned defects, but with less frequency. The assessment of human semen quality must be complex and coordinately without depreciation of the other methods of semen analysis.

Abstract
Biochemical, cytological and morphological studies in Wistar male rats. For N-hexane inhalation treatment, dynamic exposure chambers maintaining a concentration of 5,500 mg/m3 over 5 hours per day were used for 8 days. Immediately there after, the animals were given a single whole-body exposure to 4 Gy X-rays. Bronchoalveolar lavage fluid (BALF) was obtained from removed lungs. Lung homogenates were prepared subsequent to intracapillary lung perfusion via the right cardiac ventricle. Short-term n-hexane inhalation treatment was found to increase BALF total cell counts, predominantly alveolar macrophages (AM); elevated activities in lactate dehydrogenase (LDH) and alkaline phosphatase (ALP) evidenced injury affecting type I and type II pneumocytes over early post-treatment times. Whole-body irradiation alone moderately decreased AM numbers in respiratory pathways. Exposure to both agents combined resulted in depressed activity of a major antioxidant enzyme, superoxide dismutase, and diminished contents of nonprotein sulfhydryl groups in the lungs. Most of the endpoints recorded underwent greater change in the case of combined treatment, indicating synergistic action of n-hexane and ionizing radiation with regard to the biological effects studied.

Abstract
Rats received a protein-deficient standard diet and, separately at different hours of the day, protein (casein). The control group was given the standard diet added with casein. The livers of the rats were examined for histological and ultrastructural changes. The smallest changes were observed in animals which had received protein at eight o'clock. The control animals and the animals which had received protein at thirteen and nineteen o'clock, respectively, showed slight fatty infiltration of the liver.
