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.

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.

The aim of the study was to analyze the physicochemical synthesized complex 3 [(1,3- thiazol -2- ylimino) methyl)]-4H- chromene -4 -one with tetrachloroplatinate(II) dipotassium and determination peroxidase activity and glutathione (GPX) in red blood cells of cancer patients and healthy subjects. Materials and methods. Tests were carried out with the approval of the Bioethics Committee No. RNN/260/08/KB. Blood was collected into tubes with anticoagulant (heparin lithium). Determination of glutathione peroxidase activity was performed by methods of Little and O'Brien in 20 person groups hospitalized at the Department of General and Colorectal Surgery Veterans General Hospital in Łódź. Results. The study was an increase of activity in the control without the compound and after the introduction of the complex relative to the treatment groups. In healthy subjects, without the use of glutathione peroxidase complex averaged 73.25 ± 23.88 U / g Hb after application of the compound corresponds to the reference group 81.01 ± 25.94 U / g Hb. In contrast, in patients without the use of the complex activity amounted to 42.85 ± 27.49 U / g Hb. In the study group, which uses synthesized complex GPX activity corresponds to 67.72 ± 13.44 U / g Hb. Conclusions. The obtained results underline that the introduction of significant blood antioxidant complex research has a significant impact on the results of the determinations. Statistically significant (p < 0.05) difference occurred in both test and no relation to the administration of the complex in relation to the control of 1. 2. [ABSTRACT FROM AUTHOR]
