Abstract
Daylight is an important factor necessary for the proper embryonic development of birds, which raises the question, what happens when birds nest in relatively dim sites? The study experimentally tested whether there is a relationship between light conditions at the nesting site and the protoporphyrin-based pigmentation in the eggshell of the Great Tit (Parus major). We hypothesised that at lower light levels, eggs are less pigmented to increase the amount of light reaching the embryo. Our study system consisted of two types of nest boxes: "dark", in which the only source of light was the entrance hole, and "bright", which had two additional side windows. Photographs of clutches taken during the incubation period were used to quantify eggshell pigmentation. Multispectral image analyses were performed to measure variables correlating with protoporphyrin content, such as spot brightness, average spot size, spotting coverage, and spot red chroma. Repeatability analysis indicated that eggshell colouration characteristics were significantly and moderately repeatable between eggs from a single clutch, which suggests that they are under genetic and environmental control. However, none of the pigmentation traits differed significantly between the two types of nest boxes. We speculate about other ecological aspects that might have influenced the observed variability in eggshell pigmentation.

Abstract
Inflammation is an etiological factor of various chronic diseases contributing to more than 50% of worldwide deaths. In this study, we focus on the immunosuppressive role of the programmed death-1 (PD-1) receptor and its ligand (PD-L1) in inflammatory-related diseases, including chronic rhinosinusitis and head and neck cancers. The study included 304 participants. Of this number, 162 patients had chronic rhinosinusitis with nasal polyps (CRSwNP), 40 patients had head and neck cancer (HNC) and there were 102 healthy subjects. The expression level of the PD-1 and PD-L1 genes in the tissues of the study groups was measured by qPCR and Western blot methods. The associations between the age of the patients and the extent of disease and genes' expression were evaluated. The study showed a significantly higher mRNA expression of PD-1 and PD-L1 in the tissues of both the CRSwNP and HNC patient groups compared to the healthy group. The severity of CRSwNP significantly correlated with the mRNA expression of PD-1 and PD-L1. Similarly, the age of the NHC patients influenced PD-L1 expression. In addition, a significantly higher level of PD-L1 protein was noticed also for both the CRSwNP and HNC patient groups. The increased expression of PD-1 and PD-L1 may be a potential biomarker of inflammatory-related diseases, including chronic rhinosinusitis and head and neck cancers.

Abstract
INTRODUCTION The clinical syndrome that includes asthma, nasal polyps and hypersensitivity to nonsteroidal anti-inflammatory drugs is referred to as airway disease exacerbated by nonsteroidal anti-inflammatory drugs. Patients usually have the most severe form of nasal polyps. Asthma and chronic rhinosinusitis with nasal polyps share a common inflammatory profile, involving type 2 helper T lymphocytes. T-cell activity can be inhibited via the programmed death receptor, PD-1, leading to modulation of the immune response. Therefore, the purpose of this study is to evaluate the expression of genes encoding PD-1 and its ligand PD-L1 in nasal polyp tissue in patients with asthma exacerbated by non-steroidal anti-inflammatory drugs and to correlate the results with clinical data. MATERIAL AND METHODS The material used for the study consisted of 54 tissue sections of nasal polyps. In the specimens, the expression of PD-1 and PD-L1 genes was determined at the mRNA level by qPCR. Statistical analysis was used to evaluate the results of the study. RESULTS The expression of PD-1 and PD-L1 genes in the tissue of polyps was statistically significantly higher than in the nasal mucosa of patients in the control group. In addition, there was a correlation between the expression of both genes at the mRNA level and the severity of nasal polyps in the paranasal sinuses analyzed from computed tomography images of the paranasal sinuses and assessed using the Kennedy scale. CONCLUSIONS Determining the expression of PD-1 and PD-L1 genes may provide a marker for the severity of polypoid lesions. In addition, learning more about the PD-1/PD-L signaling pathway and how it can be modulated may provide a potential therapeutic strategy for patients with inflammatory diseases.

Abstract
BACKGROUND Chronic rhinosinusitis (CRS) is a group of heterogeneous diseases characterized by epithelial inflammation and tissue eosinophilic infiltration. IL-5, POSTN, and IL-33 are important factors that act as chemoattractants for eosinophils, and a tissue-remodeling protein positively correlated with eosinophils in blood and mediators of eosinophilic infiltration. The aim of the study was to determine the expression of IL-5, POSTN and IL-33, at the gene and protein levels, in eosinophilic CRS with nasal polyps (CRSwNP) and without nasal polyps (CRSsNP), and to correlate this expression with clinical severity. MATERIALS AND METHODS The study included 40 CRSwNP patients and 53 CRSsNP patients and 40 control subjects. The expression of IL-5, POSTN and IL-33 mRNA was determined in sinonasal mucosal samples and in nasal polyp tissue by real-time PCR. Protein levels in the serum of CRSwNP patients were measured by ELISA. Computed tomography was evaluated according to Lund-Mackay scores, and visual analog scale scores were assessed. RESULTS NP tissue demonstrated significantly higher IL-5 and POSTN mRNA expression than the sinonasal tissue in the CRSsNP and CRSwNP groups. CRS groups demonstrated elevated IL-33 mRNA expression in comparison to controls irrespective of the presence of NP. No correlation was found between IL-5, POSTN and IL-33 mRNA expression and disease severity. CRSwNP group demonstrated significantly higher serum IL-5, POSTN and IL-33 protein levels than controls, and this corresponds to disease severity. CONCLUSION Serum IL-5, POSTN and IL-33 levels may be important markers for classification of eosinophilic CRSwNP patients, along with disease severity.

Abstract
We examined the relationships between different types of in-group positivity and prejudice toward gay and lesbian people among heterosexual men. We assumed that prejudice toward gay and lesbian people among heterosexual men should be predicted by gender-related collective narcissism (i.e., an unrealistic belief about in-group's greatness which is contingent on external validation and extremely sensitive to any signs of threats) and not secure gender in-group identification (i.e., a confidently held in-group evaluation which is independent of the recognition of the group by others and serves as a buffer against threats). Across two studies (final Ns = 212 and 180) we found that gender-related collective narcissism (but not secure gender in-group identification or gender self-esteem) is positively related to prejudice toward gay and lesbian people among heterosexual men. The results of Study 2 demonstrated that this relationship was largely accounted for by the perceived out-group threat.

Abstract
Background:
Leonotis nepetifolia (L.) R. Br. (Lamiaceae) is a shrub traditionally used
to alleviate inflammatory conditions.
Objective:
The present study aimed at investigating the biological activity of methanolic nontransformed and transformed Rhizobium rhizogenes root extracts from L. nepetifolia against human
melanoma cells.
Methods:
Cytotoxicity and genotoxicity properties, the impact on topoisomerase I activity, and
proapoptotic activity were evaluated by the MTT test, comet assay, topoisomerase I assay, and
fluorescence-activated cell sorting analysis. Moreover, the expressions of p53 were examined by
qPCR and Western blot analysis. Docking studies were conducted to assess the potential interactions of the identified phytochemicals with the p53 binding protein Mdm-2, and computational
analyses exhibited their antioxidant potential.
Results:
Both extracts showed cytotoxic potential against human melanoma cells, but generally the
activity was more potent for transformed roots than untransformed (IC50 760 μg/mL and 980
μg/mL, respectively). A similar effect was revealed during the evaluation of genotoxic and
proapoptotic properties. Moreover, the expression of p53 was also found to be increased after extract treatment. The most dominant identified compounds in both extracts were as follows: (+)-
catechin, p-coumaric acid, m-coumaric acid, and (+)-rosmarinic acid. Docking studies and computational analysis showed that (+)-rosmarinic acid possesses the highest binding affinity to the p53
binding protein, Mdm-2, and exhibits the best antioxidant property from the most commonly identified phytochemicals.
Conclusion:
Our findings revealed the potential of L. nepetifolia transformed root extract as a
source of bioactive compounds with cytotoxic, genotoxic, and proapoptotic activity against human
melanoma cells as well as antioxidant properties.

Abstract
To date, there has been no systematic examination of cross-cultural differences in group-based shame, guilt, and regret following wrongdoing. Using a community sample (N = 1358), we examined people's reported experiences of shame, guilt, and regret following transgressions by themselves and by different identity groups (i.e., family, community, country) in Burkina Faso, Costa Rica, Indonesia, Japan, Jordan, the Netherlands, Poland, and the United States. We assessed whether any variation in this regard can be explained by the relative endorsement of individualistic or collectivistic values at the individual level and at the country level. Our findings suggest that people's reported experience of these emotions mostly depends on the transgression level. We also observe some variation across individuals and countries, which can be partially explained by the endorsement of collectivistic and individualistic values. The results highlight the importance of taking into account individual and cultural values when studying group-based emotions, as well as the identity groups involved in the transgression.

Abstract
Plant parasitism by other plants, combined with abiotic environmental stress, offers a unique opportunity to study correlational nutritional relationships in terms of parasite-host interactions and their functional roles in nutrient cycling in ecosystems. Our study analysed the transfer of selected mineral elements, including heavy metals, from soil to different organs in hosts (Punica granatum and Fraxinus angustifolia) and from hosts to the expansive holoparasite (Orobanche laxissima) in cinnamonic soil habitats in Georgia (Caucasus). We also identified other correlated trophic and bioactive effects in the parasite-host relationship. O. laxissima was characterized by a high accumulation tendency for micro- and macroelements, such as K and Ca, and heavy metals, such as Zn, Ni, and Cd. Parasites can reduce the concentration of heavy metals in host tissues owing to this high accumulation tendency. In total, 85 compounds were identified in the examined parasite and its hosts. Despite the distinct phytochemical content of species of the infected host, the parasite produced specific metabolites with dominant phenylethanoid glycosides (PhGs), with acteoside and crenatoside being the primary dominant compounds - ca. 98% of all polyphenols. Polyphenols in parasite specimens that are correlated with Cu and Zn are antagonistic to polyphenols correlated with Fe, Pb, Cr, and Ni. The profile of polyphenols in the host species was both qualitatively and quantitatively distinct from the profile of the compounds in the parasite and between hosts (only acteoside in group PhGs was common between the parasite and Fraxinus host), which indicates the existence of a unique compound biosynthesis pathway in the parasite. Our results demonstrated that the parasite, particularly in its flowers, exhibited higher polyphenol content, antioxidative effects (ABTS-+, DPPH, and FRAP), and inhibitory effects.

Abstract
Recently, the interest in mushroom consumption has been growing, since their taste and low calorific value are appreciated, but also due to their nutritional value. In determining the usefulness of mushrooms in the human diet, it is important to consider the conditions of their occurrence to perform the assessment of bioaccumulation of minerals. The aim of the study was: (a) to determine the content of selected macronutrients (P, K, Ca, Mg, Na) in fruiting bodies of Boletus edulis, Imleria badia, Leccinum scabrum and the soils, (b) to determine their bioaccumulation potential taking into account the habitat conditions, and (c) an attempt to estimate their role in covering the requirement for macronutrients of the human organism. The research material was obtained in the NW of Poland: Uznam and Wolin, the Drawa Plain and the Ińsko Lakeland. In the soil, we determined the content of organic matter, pH, salinity and the content of absorbable and general forms of macronutrients. The content of macronutrients in mushrooms was also determined. Chemical analyses were performed using the generally accepted test methods. The study showed that in NW Poland, B. edulis grew on the acidic soils of Arenosols, and I. badia and L. scabrum grew on Podzols. The uptake of K, Mg and Ca by the tested mushrooms was positively, and P and Na negatively correlated with the content of these elements in the soil. The acidity of the soil affected the uptake of K and Mg by mushrooms. There was no effect of the amount of organic matter in the soil noticed on the content of macronutrients (except sodium) in mushrooms. Among the studied macronutrients, none of the mushrooms accumulated Ca, while P and K were generally accumulated in the highest amounts, regardless of the species. Each of the other elements was usually accumulated at a similar level in the fruiting bodies of the species we studied. The exception was I. badia, which accumulated higher amounts of Mg compared to B. edulis and L. scabrum. Mushrooms can enrich the diet with some macronutrients, especially in P and K.

Abstract
(1) Background: The interaction of the programmed death receptor (PD-1) with its ligand 1 (PD-L1) allows cancer cells to escape from the control of the immune system. Research evaluating the expression of immune checkpoint genes in the tissues of laryngeal tumors may contribute to the introduction of new effective immunotherapeutic methods in this group of neoplasms. The aim of this study was to evaluate the expression of the gene for the programmed death receptor (PD-1) and its ligand (PD-L1) in laryngeal tumors (T1, T2, T3) in patients without lymph node involvement and distant metastases. (2) Methods: The study included 73 patients: 39 of them were diagnosed with carcinoma planoepiteliale keratodes (study group) and 34 with nasal septal deviation undergoing septoplasty (control group). Biological material for molecular tests (Real time PCR) was collected during surgical procedures. Furthermore, all study participants completed a questionnaire regarding, among others, smoking and body weight. (3) Results: Gene expression for programmed death receptor 1 (PD-1) and its ligand 1 (PD-L1) was, statistically, significantly higher (p < 0.0001) in tumor tissue than in unchanged mucosa. Moreover, it was found that the greater the tumor size, the higher the expression level of the tested molecules. (4) Conclusions: Although further research on the role of the PD-1/PD-L1 pathway in laryngeal tumors is necessary, the presented reports are promising and may constitute a contribution to considerations on the introduction of targeted immunotherapy with anti-PD1 and anti-PD-L1 monoclonal antibodies in the treatment of these tumors.

Abstract
Three experiments investigated the influence of penile erection on ascriptions of mental capabilities to men. Drawing on sexual objectification literature and the distinction between agency and experience in mind perception, three competing predictions were formulated. The mind redistribution hypothesis assumed that penile erection would lower agency and heighten experience attributions, the animalistic dehumanization hypothesis predicted the decrease in agency, but not experience, and the literal objectification hypothesis implied the simultaneous decrease in both agency and experience. In Experiment 1 (N = 219; 128 females), erection salience lowered agency, but not experience capabilities ascribed to male targets. Experiment 2 (N = 201, 113 females) replicated the negative effect of erection salience on perceived agency (but not experience) and revealed that erection salience lowered intentions to hire a male target. This effect was explained with the loss of perceived agency. Experiment 3 (N = 203, 98 females) verified the causal relationship between penile erection, agency and hiring intentions. Taken together, these results supported the animalistic dehumanization hypothesis.

Abstract
Introduction: The primary aim of this research was to evaluate the oxidative stress markers and the level
of oxidative DNA damage in the pathogenesis of head and neck cancer.
Materials/Methods: Sixty-two subjects matched for age and gender, including 31 patients with head and neck
cancer and 31 control patients without cancer symptoms, were enrolled in our study. In our
work, the activity of antioxidant enzymes: catalase (CAT), superoxide dismutase (SOD) and
glutathione peroxidase (GPX), as well as a total antioxidant status (TAS), were estimated.
Additionally, an alkaline comet assay was used to measure the level of DNA damage in the
group of patients with head and neck cancer and the group of healthy control patients. These
tests were performed on a blood sample with and without prior incubation of dinitratebis
(1-phenyl-5-(2-hydroxyphenyl)-3-methyl-N1pyrazol-κN2)cooper(II).
Results: Significant increases of SOD, GPX CAT, TAS (P <0.001) were seen in blood from patients with
head and neck cancer and prior incubation of cooper (II) component compared to blood from
healthy controls without prior incubation of analyzed chemical. Moreover, we did not observe
any relationship between the level of DNA damage and the studied component dinitratebis
(1-phenyl-5-(2-hydroxyphenyl)-3-methyl-N1pyrazol-κN2)cooper(II) in the group of patients
with head and neck cancer or in healthy controls.
Discussion: Free radicals such as reactive oxygen species, which induce oxidative stress, may contribute
to head and neck carcinogenesis. Therefore, we suggest that modulation of pro-oxidant
/antioxidant status might be a relevant target for both prevention and therapy.

Abstract
Aim: Sudden sensorineural hearing loss (SSNHL) involves acute unexplained hearing loss, nearly always one-sided of 30dB or greater over at least three contiguous audiometric frequencies. The aetiology of SSNHL is mostly unknown. According to the literature, the causes include vascular, microbial and autoimmune problems. There is still no agreed standard treatment. The aim of the paper was to evaluate the results of combined pharmacotherapy and hyperbaric oxygen therapy in patients with idiopathic sudden deafness.
Material/Methods: The study was carried out on 40 patients with SSNHL. The patients were divided into two groups: group I – 24 patients treated with the combined pharmacotherapy and hyperbaric oxygen therapy and group II – 16 patients treated only pharmacologically. The patients from Group 1 were treated in the Centre of Hyperbaric Therapy CREATOR Ltd. in Lodz, Poland. Each patient underwent 15 sessions in a hyperbaric chamber. In all patients, the percentage of hearing loss for the selected frequencies was assessed before and after the therapy according to Sabine and Fowler.
Results: The group of 40 patie nts aged from 33 to 77 years (mean 52.4) included 21 females and 19 males. Group I consisted of 24 patients, 11 females and 13 males, group II consisted of 16 patients, 10 females, and 6 males. After therapy, the mean hearing level in all patients improved by 27.14%, in Group I – by 34.34%, in Group II – by 16.3%.
Conclusions: Early hyperbaric oxygen therapy combined with steroid therapy improves prognosis and shows good results in sudden hearing loss treatment.

Abstract
Worldwide use of electronic cigarettes has been rapidly expanding over recent years, but the long-term effect of e-cigarette vapor exposure on human health and environment is not well established; however, its mechanism of action entails the production of reactive oxygen species and trace metals, and the exacerbation of inflammation, which are associated with potential cytotoxicity and genotoxicity. The present study examines the effects of selected liquid chemicals used in e-cigarettes, such as propylene glycol/vegetable glycerin, nicotine and flavorings, on living organisms; the data collected indicates that exposure to e-cigarette liquid has potentially detrimental effects on cells in vitro, and on animals and humans in vivo. While e-liquid exposure can adversely influence the physiology of living organisms, vaping is recommended as an alternative for tobacco smoking. The study also compares the impact of e-cigarette liquid exposure and traditional cigarette smoke on organisms and the environmental impact. The environmental influence of e-cigarette use is closely connected with the emission of airborne particulate matter, suggesting the possibility of passive smoking. The obtained data provides an insight into the impact of nicotine delivery systems on living organisms and the environment.

Abstract
BACKGROUND Head and neck neoplasms stand for 6% of all malignant neoplasms worldwide. Chemotherapy has limited use due to the biological properties of the tumor (in the majority of cases moderately and poorly differentiated squamous cell carcinoma). The fundamental molecule used in treatment is cisplatin and its derivates, that can be associated with fluorouracil. The new chemotherapeutic agents are not in common use during the treatment of head and neck malignancies. However, the use of low molecular weight complexes Pd (II) carries the potential of being more effective in therapy. MATERIAL AND METHODS Fifty-one patients, 30 men and 21 women (aged 52.9 ± 12.1 years) with head and neck cancer were included in the study. Fifty-one healthy subjects, 31 men and 20 women, (aged 54.1 ± 14.7 years) years formed the control group. Antioxidant enzymes, superoxide dismutase, and catalase activities in erythrocytes were examined. RESULTS An increased level of antioxidant enzymes was seen in the blood samples from patients with head and neck cancer after incubation with Pd (II) complex. In the group we obtained a statistically significant result p = <0.001. DISCUSSION That project may contribute to the development of new, more efficient head and neck cancer treatment strategies. In our opinion, the results can be used in the future to develop a valuable prognostic marker of the disease. This is important because the initial phase of cancer is asymptomatic. The search for factors involved in pathogenesis translates into economic benefits and makes therapy more effectiveness through the reduction of treatment expenses.

Abstract
HA preparations in intraarticular injections have been applied in medicine since 1986 and became widely used in Poland at the beginning of the 90s of the twentieth century. Since then, numerous cases of successful application of intra-articular injections (the so called viscosupplementation) have been described in Polish and foreign literature. Changes in the molecular mass of hyaluronic acid and the related specific spatial structure result in different metabolic and immunological properties. Presently, in clinical practice, it is indicated to use the preparations produced by selected manufacturers who offer different forms of HA, containing different percentage of active substance (1 to 2.5%) and different molecular mass, making the desired number (1-5) of intra-articular injec-tions possible, depending on the type and intensity of a specific disease unit. Numerous studies have been con-ducted to confirm the effectiveness of treatment using hyaluronic acid. In Poland a research program was implemented to assess the practical application of 2 ml of Biolevox HA preparation in 2.2% concentration. During the study 15,000 patients were subjected to analysis. The physicians participating in the study injected the hyaluronic acid, in that case, Biolevox HA, to the knee joint, in patients with osteoarthritis, chondromalacia, knee joint injuries and other conditions.

Abstract
Heterocyclic compounds containing nitrogen ions, like pyrazoles, aziridines, diaziridines and their metal ion complexes with Cu(II), Zn(II) and Ru(III) and others exhibit a wide range of biological activity, including mainly anti-inflammatory, antioxidant, anticancer, and antimicrobial properties. Biological significance of these molecules and thus their potential use in medicine has driven growing interest into their coordination chemistry. A knowledge of the relationship between the structure of chemical compounds and their activity is needed for the synthesis of the preparations possessing the most beneficial features. The choice of interposed substituents may improve biocidal and antitumor action, reduce the toxicity of the initial substance, or even completely eliminate its adverse effects for healthy tissues. The main aim of this review paper is to present the current state of knowledge concerning the synthesis and biological activity of complexes with small heterocyclic ligands containing transition metal ions.

Abstract
INTRODUCTION Chest pain is one of the symptoms of lung cancer.Chest pain disrupts patient's functioning in somatic and psychic area. PURPOSE Whether the existence of chest pain affects the level of perioperative anxiety in lung cancer patients. Is there a relationship between everyday functioning due to the chest pain and the level of perioperative anxiety? Is there a relation between anxiety associated with pain and gender? What is the cause of anxiety in this group of the patiens? METHODOLOGY The study was conducted among 150 patients with lung cancer before the scheduled surgery. Data was collected with the use of questionnaire assessment of perioperative anxiety level in patients with lung cancer. RESULTS The chest pain before the surgery was confirmed by 63 (42%) patients, in case of 87 (58%) patients it was not identified. Chest pain was in case of 48% women and 36% men. 50 (33,3%) research participants who experienced chest pain and 35 patients (23,3%) without this symptom declared experiencing perioperative anxiety. In patients with lung cancer, the correlation: between chest pain and perioperative anxiety was (Z = -4.67; p< .001); between the difficult daily functioning of pain and perioperative anxiety was (Z = -4.72; p< .001); between gender and perioperative anxiety associated with pain was (Z = -3.24; p = 001).Patients afraid of: pain (37,3%), breathing problems (24,0%), physical disability (16,0%), eating problems (12,0%) sleep disorders (9,3%), nothing (1,3%). CONCLUSIONS Patients with chest pain exhibited significantly higher of perioperative anxiety levels than non-symptomatic patients, as well as higher anxiety levels due to deteriorated daily functioning caused by the disorder. Women had a higher level of anxiety associated with pain than men before the surgery. Patients with lung cancer were most afraid of pain in the perioperative period.

Abstract
The musculoskeletal diseases and injuries affect not only the musculoskeletal system itself, but also the closely related structures, such as blood vessels and nerves (both within the central and the peripheral nervous system). If these relationships are neglected or the directed neuroprotective and neuro-regeneration therapy is delayed, the final effect of the treatment is compromised. The aim if this paper is describing the important medical and social problem of peripheral neuropathies from the point of view of epidemiology, etiopathogenesis, imaging diagnostics and complex medical procedures using modern approaches and techniques, based on the available literature.

Abstract
INTRODUCTION Our aim was to determine the effect of the single nucleotide polymorphisms (SNP) -93G>A of the MLH1 gene (rs1800734) and Gly322Asp of the MSH2 gene (rs4987188) on the risk of colon cancer (CC) and identify any relationship with clinical factors. MATERIAL AND METHODS The study included 144 unrelated patients with sporadic CC (71 males; mean age: 61.7 ±11 years) and 151 control patients (74 males; mean age: 63 ±11 years). DNA was extracted from peripheral blood lymphocytes, and genotypes were determined by polymerase chain reaction-restriction fragment length polymorphism. RESULTS In our population, the homozygous G/G genotype of the -93G>AMLH1 gene increased the risk of sporadic CC (OR = 2.07; 95% CI: 1.11-3.83; p < 0.02). For A/G and A/A genotypes, the MLH1-93G>A polymorphism was significantly more common in women (p = 0.034). The SNP demonstrated differences in allele distribution according to the location of the tumor, i.e. right vs. left side (p = 0.014), and disease recurrence (p = 0.022). Significant differences were found in the occurrence of Gly322Asp of MSH2 with regard to primary and recurrent disease (p = 0.001). CONCLUSIONS The -93G>AMLH1 polymorphism plays an important role in evaluating the risk of sporadic CC. It can also be used as an indicator in some patients with left-sided and recurrent tumors. MSH2 Gly322Asp is a potential marker in patients with risk of recurrence.

Abstract
Enterococcus faecalis represents an important factor of hospital-associated infections (HAIs). The knowledge on its evolution from a commensal to an opportunistic pathogen is still limited; thus, we performed a study to characterise distribution of factors that may contribute to this adaptation. Using a collection obtained from various settings (hospitalised patients, community carriers, animals, fresh food, sewage, water), we investigated differences in antimicrobial susceptibility, distribution of antimicrobial resistance genes, virulence-associated determinants and phenotypes, and CRISPR loci in the context of the clonal relatedness of isolates. Bayesian Analysis of Population Structure revealed the presence of three major groups; two subgroups comprised almost exclusively HAI isolates, belonging to previously proposed enterococcal high-risk clonal complexes (HiRECCs) 6 and 28. Isolates of these two subgroups were significantly enriched in antimicrobial resistance genes, presumably produced a polysaccharide capsule and often carried the aggregation substance asa1; distribution of other virulence-associated genes, such as esp and cyl, formation of a biofilm and gelatinase production were more variable. Moreover, both subgroups showed a low prevalence of CRISPR-Cas 1 and 3 and presence of small CRISPR2 variants. Our study confirms the importance of HiRECCs in the population of E. faecalis and their confinement to the hospital settings.

Abstract
Little is known about the inflammatory response of the endometrium in repeat-breeding cows with subclinical endometritis (SE). The objective of this study was to evaluate the mRNA expression of prostaglandin-endoperoxide synthase 2 (PTGS 2), prostaglandin F2α synthase (PTGFS) and prostaglandin E2 microsomal synthase 1 (mPTGES 1) in the endometrium of repeat-breeding cows with and without SE. SE was diagnosed cytologically using the cytobrush method, with the threshold being set at 5% polymorphonuclear neutrophils. Biopsy samples were obtained from the endometrium of repeat-breeding cows with SE (n = 10) and without SE (n = 10). The mRNA expression of the synthases was evaluated using qRT-PCR. Significantly higher (P < 0.05) expression of the PTGS 2 gene was detected in the repeat breeders with SE, whereas there was no significant difference in the expression of PTGFS and mPTGES 1 mRNAs between repeatbreeding cows with SE and those without it (P > 0.05). Our study confirms that increased endometrial expression of the PTGS 2 gene is involved in the inflammatory response in repeat breeders.

Abstract
UNLABELLED The cholecystectomy procedure is the most routinely performed intervention in general surgery. The current international gold standard is via the laparoscopic approach. It is a safe, minimally-invasive procedure; however, it is associated with complications in 1% of cases. The aim of the study was to analyze patient feedback, by means of a survey, to determine how much knowledge patients possessed about their disease state and proposed surgical intervention, based primarily on information contained within the informed consent form developed by the Association of Polish Surgeons. MATERIAL AND METHODS This study involved the participation of 51 patients who underwent laparoscopic cholecystectomy, indicated by a diagnosis of gallstones, in the years 2014 and 2015. RESULTS Despite having signed the informed consent form, there was considerable variation among the responses given to the survey by the 51 patients in this study. Some patients' responses were tangential to the questions asked; many patients did not respond to any of the sub points. CONCLUSIONS Given that this study is based on a small sample size of patients, it must be presumed that the process by which the patient declares his or her informed consent requires further consideration with respect to the means by which it is obtained. The authors of this study thus recommend that multimedia resources be harnessed as part of the process of obtaining the informed consent of patients prior to surgical intervention.

Abstract
Substances of natural origin are the subject of growing interest on the part of both researchers and doctors. One of the well known herbal medicines extensively examined in terms of clinical and pharmacological is artichoke (Cynara scolymus L.), which was used in European medicine from the 18th century. His multidirectional treatment is a documented fact and it is associated with treatment of dyspepsia, influence of active substances contained in artichoke on plasma lipid levels and with a strong antioxidant effect of the artichoke extract--due to this properties, artichoke compounds have a protective effect on liver cells.

Abstract
The aim of this study was to develop and validate the method of cynarin and luteolin, the main constituents of artichoke (Cynara scolymus L.) leaf extract, determination in plasma. The compounds were separated using the high-performance liquid chromatography technique with diode array detection (HPLC-DAD). The analysis was preceded by liquid-liquid extraction using as the extracting agent ethyl acetate. The HPLC separation was performed on C18 column under gradient conditions using a mobile phase - 0,05% trifluoroacetic acid in water and methanol. The detector was set at lambda=330 nm. The validation was related to linearity, sensitivity (LOD and LOQ), accuracy and repeatability. In the validated method the linearity was achieved within concentration range 1,5625 - 50,0 microg/cm3 for the cynarin (R2=0,9989) and 1,5625 - 200,0 microg/cm3 for the luteolin (R2=0998). The limits of detection for cynarin and luteolin was: 0,75 microg/cm3 and 0,1 microg/cm3 and the limits of quatification: 2,25 microg/cm3 and 0,2 microg/cm3, respectively. Coefficient of variation for the inter-day and the intra-day analysis, which is a precision and accuracy parameter, do not exceed 10%. Recovery was 67% for the cynarin and 96% for the luteolin. The practical application of this method was proved by analysis of plasma samples from rats. The animals were administrated artichoke leaf extract - orally and intraperitoneally at a dose of 3 g/kg body weight or pure substances - intraperitoneally at a dose 1 mg/kg of luteolin and 0,5 mg/kg of cynarin. The presence of investigated compounds was proved only in samples after intraperitoneal administration of pure substances. The developed method is used to determine simultaneously cynarin and luteolin, after intraperitoneal administration of pure compounds.

Abstract
OBJECTIVES Oxidative stress (OS) plays an important role in the pathogenesis of multiple sclerosis (MS). In MS patients depression is often observed. Cryotherapy might have an effect on OS. The aim of this study was to compare the effects of whole body cryotherapy (WBCT) on changes in total antioxidative status (TAS) of plasma and activities of antioxidative enzymes in erythrocytes from depressive and non depressive MS patients. METHODS Twenty-two MS patients with secondary progressive disease course (12 depressive and 10 non depressive) were treated with 10 exposures in a cryochamber. Before and after WBCT the plasma TAS and the activities of superoxide dismutase (SOD) and catalase (CAT) in the erythrocytes were measured. RESULTS The level of TAS in depressive MS group was significantly lower than in non depressive MS (P < 0.0003). WBCT increased the level of TAS in depressive (P < 0.002) more than in non depressive MS patients (P < 0.01). WBCT treatment of MS patients resulted in the significant increase of TAS level in plasma but had no effects on activities of SOD and CAT. CONCLUSIONS Our results indicate that WBCT suppresses OS in MS patients, especially in depressive patients.

Abstract
OBJECTIVE There is evidence that multiple sclerosis (MS) is not only characterized by immune mediated inflammatory reactions but also by neurodegenerative processes. Neutralization of oxidative stress and excitotoxicity, might represent a therapeutic approach to provide neuroprotection in MS. The purpose of this study was to compare changes in total antioxidative status and activities of chosen antioxidative enzymes, such as: SOD, CAT in erythrocytes of patients with MS before and after using WBCT with control group. MATERIALS AND METHODS 32 patients with multiple sclerosis (ICD10-G35) and 20 healthy subjects were recruited for the study. The examined MS group (n=16) was treated with a series of 10 daily exposures in a cryogenic chamber (2-3 min, from -120 degrees C to -110 degrees C) and program of exercises. The control MS group (n=16) had only exercises. Plasma TAS as well as SOD and CAT activities in erythrocytes were measured. RESULTS The level of TAS in MS patients was distinctly reduced compared to healthy subjects. After two weeks of WBCT treatment an increase of TAS in the whole examined group (p>0.01) were observed in relation to control MS group. There was not increase of CuZnSOD and CAT activities. CONCLUSION Our results suggest positive antioxidant effects of WBCT as a short-term adjuvant treatment for patients suffered due to MS.

Abstract
Colorectal cancer is a serious medical and economic problem in Poland, as the detection and results of its treatment are very low. Due to this fact, medical research is still conducted in order to find out the symptoms of this tumor and proper preventive measures. According to one hypothesis of carcinogenesis, the process of creating the tumor begins and develops when the balance between the production of reactive oxygen species (ROS) and their deactivation by the "antioxidant protective barrier of the organism" is disturbed. As a result of this theory, it has been decided to examine the plasma concentration of the dietary minerals which work as antioxidants. The results entailed conclusions which prove the free radicals theory of carcinogenesis. They also confirm the part which the antioxidant protective barrier plays in the defence against ROS and their carcinogenic consequences.

Abstract
UNLABELLED Coxarthrosis results in physical limitations (hypokinesis) and a necessity to change one's life style to the one that does not require much movement. Physical inactivity leads rapidly to metabolic processes inhibition. The processes of protein, carbohydrate and lipid catabolism intensify. Abnormal metabolism of polyunsaturated fatty acids occurs, which consequently leads to the development of reactive oxygen species (ROS) and to the acceleration of lipid peroxidation. Therefore, it is well-founded to seek for a new group of compounds demonstrating interesting biochemical properties. Among such already known compounds are chromone, azole and flavone derivatives, known for their oxidative properties. The aim of the study was to assess the antioxidant enzymes: catalase (CAT) and glutathione peroxidase (GPX) in erythrocytes in 25 patients suffering from coxarthrosis in comparison with healthy persons. MATERIALS AND METHODS The activity of catalase was determined in erythrocytes using the method of Beers and Sizer at 240 nm on the Beckman spectrophotometer. The activity of glutathione peroxidase was estimated using the method of Little and O'Brien at 412 nm on the Beckman spectrophotometer. The research was conducted with the permit of the Bioethics Committee No RNN/260/08/KB dated 20.05.2008. Blood for the tests was taken from periulnar vein to anticoagulant tubes (EDTA). The group consisted of 25 patients hospitalized in the Trauma and Orthopaedic Ward of the Hospital in Łódź. RESULTS The results of the tests on erythrocytes in the patients with physical limitations reveal the increase of glutathione peroxidase and catalase activity by about 50% in all patients, who were administered the dichlorobis (N1-dichloromethyl-3,5-dimethylpyrazole, copper (II) compound in comparison to the control group, where the foregoing compound was not used. CONCLUSION The research results significantly emphasise that adding of new chemical compounds to blood in investigation of oxidative properties has a considerable influence on the activity of the selected enzymes (catalase and glutathione peroxidase) in comparison to the control group. The research reveals an increase of the activity of all antioxidant enzymes, where newly synthesized chemical compounds were used. The results of antioxidative capacity tests confirmed that complex compounds with Cu (II) ions have a significant influence on the antioxidative status. The studies on the foregoing enzymes also indicate that overproduced free radicals participate in the whole course of the coxarthrosis.

Abstract
UNLABELLED Coxarthrosis used to be referred to as the "doctors' cross" pointing to the difficulties of the treatment. Degenerative processes in the bones usually concern large joints: knee joints in 25-40% of cases, similarly in case of hip joints. Because of the role the joints play, the arthrosis may result in physical limitations or disability. The aim of the study was to evaluate the activity of catalase and superoxide dismutase (CuZn-SOD) in erythrocytes in patients suffering from the coxarthrosis--as the studied group and in healthy people--as the control group. MATERIALS AND METHODS Determining the activity of catalase and superoxide dismutase in the group of 17 patients hospitalized because of coxarthrosis. RESULTS In the study about 90% increase of the activity of the enzymes was determined in the studied group, in which the chemical compound 3{(2-aminothiazolyl)methylene}4H-1-benzopyran-4-one was added to the blood, in comparison with the control group. CONCLUSION The results of the test on catalase and superoxide dismutase clearly indicate that the free radicals participate in the whole course of coxarthrosis.

Abstract
INTRODUCTION Short- or long-lasting hypokinesis is to a large degree the consequence of negative habits of human beings towards a comfortable and more sedentary lifestyle. The period of decreased physical activity can cause disturbance in the balance between systemic processes of the oxidation and reduction, which leads to an increase in reactive oxygen species (ROS) and oxidative stress generation. The aim of the study was to determine the effect of melatonin administration on the cellular superoxide dismutase (CuZn-SOD) activity in red blood cells of patients with short- and long-term hypokinesis as compared to the group of subjects with normal physical activity. MATERIAL AND METHODS The study included 33 subjects with immobilization. The study group was divided into two subgroups (depending on hypokinesis duration): group A: 15 subjects classified for total hip alloplasty (a short-lasting decrease in physical activity); group B: 18 subjects suffering from multiple sclerosis or the stroke of brain (the long-term hypokinesis). The control group (group C) comprised 17 subjects with normal physical activity. Melatonin was applied at a dose of 5 mg daily, one hour before sleep. The CuZn-SOD activity in red blood cells was determined, according to the Misra and Fridovich method, in two periods: 1) on the first day, 2) on the 10th day (group A), and 30 days (group B) after melatonin administration. RESULTS A slight increase in CuZn-SOD activity (+3.1%) was observed in group A 10 days after alloplasty and melatonin administration as compared to group B, where a considerable rise in the enzyme activity (+23.3%) was found 30 days after rehabilitation and melatonin supplementation. The average CuZn-SOD activity in both investigative groups was lower than that in the controls (group C). CONCLUSIONS It was estimated that the short- and long-lasting hypokinesis leads to an increase in ROS generation, what is confirmed by the increase in CuZn-SOD activity. The results of the study on superoxide dismutase activity indicate that oral administration of melatonin for the period of 30 days has a more favorable influence on antioxidative processes than 10-day's melatonin intake.

Abstract
UNLABELLED Colorectal cancer is a serious medical problem. According to one hypothesis of carcinogenesis, tumour creation process begins and develops when the balance between the production of reactive oxygen species (ROS) and their disactivation by the antioxidant protective barrier of the organism is disturbed. THE AIM OF THE STUDY was, following this theory, to examine the plasma concentration of the dietary minerals with antioxidant properties. MATERIAL AND METHODS The research material was the blood of 8 people, taken to vacuum test tubes with an anticoagulant - 4 ml of sodium heparin. The activity of catalase was marked following Beers method, while the activity of superoxide dismutase according to H.P. Misra and J. Fridovich method. RESULTS The results show that the copper complex added, i.e. dichlorine(3,4,5-trimethyl-N1 - pyrazol-1yl) Cu(II) from derivatives of azoles, has a large impact on the activity of selected enzymes. After adding it, their activity increased by ca 67% in comparison with the control group. It proves the efficacy of this compound. CONCLUSIONS The results prove the free radicals theory of carcinogenesis. They also confirm the part which the antioxidant protective barrier plays in the defense against ROS and their carcinogenic consequences.

Abstract
It is very important for contemporary medicine to create new effective cytotoxic compounds of platinum with better clinical tolerance. Harmful elements which exist in food delivered to a human organism may either get inactive or activate complex processes which may to lead to illnesses such as tumors. One of these elements are. Undoubtedly, free radicals. They destroy, among other things, the DNA, causing changes in the genetic code and its mutations. More recently came the publication of speaking a lot about the capabilities of the organism to defend against the above-mentioned factors. Eating adequate amounts of fruits and vegetables contain antioxidants in its composition contributes positively to our body and reduces the risk of cancer.

Abstract
UNLABELLED Chemotherapy is an important field of clinical medicine and pharmacology Chemotherapy is the main method of treating the neoplasm. It involves treating the neoplastic disease with the use of natural or synthetic anticancer drugs commonly known as the cytostatics. The cancer therapy involving the cytostatics is a difficult and not always effective process, which requires taking into consideration the mechanisms of action, pharmacokinetics and the dosage schemas. The complexity of the chemotherapy is influenced by: still incomplete knowledge of causes of neoplasm formation, slight biological differences between the cancer cells and the regular cells, very small selectivity of cytostatics' action, narrow therapeutic index of the anticancer drugs, high toxicity for healthy cells and unsatisfactory anticancer activity. The aim of the study was to obtain the complex compounds of copper (II), and especially of dinitrate (V) di (3,4, 5-trimethyl-N1-pyrazol-kappaN2) copper (II), and its subsequent testing for pro- and antioxidative activity in people suffering from neoplastic diseases of the digestive tract (colorectal and gastric carcinoma). Material and methods. The activity of catalase was determined in erythrocytes patients suffering from colorectal and gastric carcinoma and in control group (hernia, chronic gastric ulcer disease and haemorrhoids) using the method of Beers and Sizer at 240 nm on the Beckman spectrophotometer. RESULTS The results of the test on catalase in patients suffering from colorectal and gastric carcinoma indicate that the addition to the blood of the complex compound of Cu(II) significantly influences the activity of the enzyme in comparison with the control group in which the substance tested was not used. In the tests a marked statistical difference was observed between the studied and the control group. CONCLUSION The results reveal that chemical compounds, that is, dinitrate (V) di (3,4,5-trimethyl-N1-pyrazol-kappaN2) copper (II), has a significant influence on the activity of catalase, the antioxidant enzyme.

Abstract
UNLABELLED The mechanism of functioning of the well-balanced protection system against free radicals is based on the mutual and synergistic activity of its all elements. One of the first organism reactions to physical effort is an elevated oxygen requirement due to an increased rate of metabolism, particularly in the skeletal muscles involved in performing physical work. In case of insufficient antioxidative system of blood plasma, free radicals attack the erythrocytic membrane externally and internally, leading to formation of considerable amounts of reactive oxygen species (ROS). The aim of this study was to evaluate the influence of dosed submaximal and maximal physical exercise on the plasma total antioxidant status (TAS) concentration in professional sportsmen and in subjects of normal physical activity. MATERIAL AND METHODS 41 rugby players (junior and senior group) and 20 men of normal physical activity (control group) were the subject of the study. The plasma TAS concentration was determined: before an effort in the control group, and after 30-minute restitution period in sportsmen. RESULTS The concentration of TAS values in subjects of normal physical activity before exercises were on average 0.65 +/- 0.15 mmol/l. In the junior group after the dosed submaximal physical exercise, the mean TAS concentration was 0.69 +/- 0.29 mmol/l, but the dosed maximal exercise lead to an increase in TAS values - 0.73 +/- 0.34 mmol/l. The higher plasma TAS concentration after the dosed submaximal physical exercise was observed in the senior group as compared to the junior group, and was on average 0.93 +/- 0.22 mmol/l. However, after the maximal exercise, the TAS concentration decreased and its average value was 0.66 +/- 0.26 mmol/l. CONCLUSIONS The results of the study indicate that the intensity of performed exercises affects the plasma TAS concentration during a single physical activity. The plasma TAS concentration was higher in sportsmen regardless of the type of effort as compared to the control group. Supplementation of micromolecular antioxidants present in nutrients ingested by the sportsmen might have influenced the study outcomes.

Abstract
UNLABELLED A pyrazole system is incorporated in many biological molecules which play an important part in genetic processes. It seems that co-ordinating biological molecules, which would serve as carriers, should contribute to minimising the toxic effects of the potential platinic drugs. AIM OF THE STUDY Assessment of in vivo biological activity, and in particular of antineoplastic activity of new platinum(II) and palladium(II) complexes. MATERIAL AND METHODS The assessment of toxicity of the compounds was made with the Deichmann and Le Blanck method. The antineoplastic activity of the new complex compounds--pyrazole derivatives with Pt(II) and Pd(II) ions was tested on mouse L1210 leukemia cell culture and on lymphatic leukemia P388. BDF1 or CDF1 mice divided into groups of 5-9 animals were subject to the tests. RESULTS Complexes 13, 21, 25, 16, 24 and 28 did not reveal any antineoplastic activity to the mouse L1210 leukemia, whereas complexes 13, 21 and 25 revealed in-vivo antineoplastic activity to the P388 leukemia, extending the mouse's survival time by about 50%. The control group consisted of mice which were administered a 14% methylcellulose solution. CONCLUSIONS As a result of the tests conducted to asses the in-vivo antineoplastic activity it was found that the 25 complex demonstrates the strongest activity to the P388 leukemia. It may be presumed that it is caused by trans configuration of the complex predisposing to the creation of interstrand cross-links. It may be also caused by the presence of the chloromethyl substituents, located on N1 nitrogen atom of the ligand, which increases the capacity of nitrogen N7 guanine alkylation in DNA.

Abstract
UNLABELLED A nitrogen ring is present in many biological molecules, which play an important part in cell division as well as in genetic information transfer. It is also a part of the purine system, which builds DNA and has potential places/spots of platinum drug co-ordination. Therefore, it may be hoped, that platinum(II) complexes with diazol ligands will have considerable affinity for DNA binding sites. The work was aimed at assessment of biological activity and especially of cytotoxic activity, of new complex connections of the selected diazols with Pt(II) and Pd(II) ions. MATERIALS AND METHODS The MTT test is aimed at the assessment of cytotoxicity of chemical compounds. It consists in the colorimetric determination of a product--farmazon, formed after adding MTT (bromide 3[4,5-dimetylo-2-ilo]-2,5-difenylotetrazolu) to the culture suspension in the presence of the compound subject to the test. All the tested Pt(II) complexes before adding to the cell cultures were dilluted in DMF. MTT tests for individual complexes were conducted on two cell lines L1210 and P388. RESULTS Compounds 13, 21 and 25 on P388 neoplastic cell revealed about three times smaller in-vitro cytotoxicity, whereas platinum(II) and palladium(II) complexes 13, 21, 25, 43, 46, revealed cytotoxicity being about 3-4 times smaller than the reference cisplatin. Complex 45 revealed eight times smaller activity and complex 44 revealed significantly small, about two hundred smaller activity. CONCLUSION Based on the MTT tests it may be concluded that compounds 13, 21 and 25 reveal selective cytotoxicity to P388 neoplastic cells.

Abstract
Free radicals are substantial elements that take part in proper function of metabolic pathways of human cells and tissues in hydrophobic as well as in hydrophilic environment. Nevertheless overproduction of above molecules causes oxidative stress, a process which is very harmful for lipids, proteins, and others molecules what reduces their normal function. To protect against adverse effects of free radicals and theirs derivatives to human body there is a group of antioxidants divided into enzymatic and non-enzymatic substances. Enzymatic antioxidants are represented mainly by enzymes such as: copper-zinc superoxide dismutase (CuZnSOD), catalase (CAT), glutathione peroxidase (GPx) and glutathione reductase (GR). Glutathione (GSH), thioredoxin (Trx), vitamins, melatonin, polyphenols, trace elements, albumin, and others function as non-enzymatic free radicals scavengers. This work in a brief way describes properties of chosen representants of non-enzymatic antioxidant system.

Abstract
The increasing interest in flavonoids means higher demand for the complex and synthetic knowledge about those substances. The following study is an overview of the contemporary knowledge about the mentioned substances, and hopefully it will magnify this topic. Flavonoids are the ingredients of many nutrition substances and a vital diet element. They are also a group of many medicines with different influence on live organisms. At the moment, there are over hundreds of bio-flavonoids identified. The phenol compounds are used as natural drugs in the cases of various sicknesses of blood, breathing, food, and urinary circuit, and in dermatology as well. The existence of these compounds in the diet, especially maintenance of their proper consumption level, is a very important element in the prevention of many diseases, such as atherosclerosis. The intensity of experimental studies on flavonoids in the last decade (mainly studies on cell cultures) showed varied attributes of these compounds. The results give hope for the use of flavonoids in prevention and neoplasmatic treatment. Phenol compounds as antioxidants may affect in many different aspects: direct reaction with free radicals, scavenging free radicals, growing dismutation of free radicals to the compounds with much lower reactiveness, chelatation of pro-oxidant metals (mainly iron), delaying or strengthening many enzymes. What is more, they can strengthen the functionality of other antioxidants, such as vitamins resolving in fat, and low-molecular substances resolving in water. The wide spectrum of the functions of flavonoids and their synthetic derivatives gives hope for the research of new chemical compounds (drugs) with exploratory characteristics.

Abstract
Reactive oxygen species (ROS) and reactive nitrogen species (RNS) are produced during variety of biological processes. Low concentration of these molecules influences cell growth, differentiation or proliferation. Above derivatives of oxygen and nitrogen take part in physiological processes such as signal transduction, regulation of protein kinases or transcription factors. ROS and RNS regulate redox balance, regulate immune responses, activate macrophages and neutrophils. Under theirs' control is cell adhesion and relaxation of smooth muscles. These molecules are very important for correct function and life of the cell.

Abstract
Contemporary coordinative chemistry is still searching new substances that might constitute good ligands for transient metal ions: Cu(II), Ni(II), Co(II), Pt(II), Pd(II) oraz Cr(III). Pyrazole and its derivatives are able to make complexes with transient metal ions. There is a connection between pharmacological and chemical structure among pyrazole derivatives used in a medical treatment. A chemical division is coincident with a pharmacological division. Pyrazole-5 derivatives are mainly analgesic, antipyretic and less anti-inflammatory and diastolic but pyrazolidyn-3.5-dion derivatives are anti-inflammatory. The main part of non-steroid anti-inflammatory drugs belonging to pyrazolone derivates has a phenyl group at the first position. The activity and toxicity of this drugs are dependent on groups being at the fourth position. For example, the dimethylamino group makes aminophenazon antianalgetic, and yet is also responsible for a big toxicity. Azole derivatives are antimycotic and are ingredients of some ointments and creams. Chemical groups at the fourth position may determine the activity and the toxicity. These days a great attention is paid on a synthesis which is linking pyrazole and ions of platinum Pt(II) and palladium Pd(III) due to anticancer properties but pharmacology is not known very well.
