Objectives: The aim of the investigation was to study the hormonal status (sex hormones: estradiol (E 2), progesterone (P), testosterone (T); non-sex gonadotropic hormones-luteinizing hormone (LH) and follicle-stimulating hormone (FSH)) of women with benign and malignant tumors of uterine body in the reproductive, menopause and postmenopause periods. Also the distribution features of the blood ABO system phenotype groups and their link to the development of uterine body tumors have been studied. Methods: The determination of hormones was made by the enzyme analysis method (ELAIZA), provided by the proper ELAIZA kits. For the study of blood ABO system antigens, internationally recognized immunoserology methods were used. Results: Investigations revealed the increased level of E 2 and T on the background of the reduced P in the blood of the women with uterine tumors in the reproductive, menopause and post-menopause period. As for gonadotropic hormones, the decreased levels of LH and FSH have also been detected. From the ABO system phenotype groups A(II) group had the highest frequency between the women with malignant uterine tumor in the reproductive age. O (I) phenotype group was the most frequent in case of menopause and post-menopause women with uterine malignant tumors. Conclusions: Hormonal imbalance creates good conditions for the proliferation of uterine tissues and hence causes the development of benign and malignant uterine tumors. The imbalance of the sex steroid and gonadotropic hormones in the blood of post-menopause women indicates on the genotoxic * Corresponding author. mechanism of cancer development on the background of age-related changes. A(II) group had the highest frequency between the reproductive age women with uterine malignant tumor, while O (I) group was the most frequent in case of menopause and post-menopause patients.
Introduction and Objectives: One of the characteristic changes of tumor formation is accumulation of genetic disorders in mitochondrial and nuclear genome. Mitochondrial disorders, from its side, are responsible for failure of metabolism, apoptosis, cell growth, formation of reactive oxygen species, etc. Overprpoduction of reactive oxygen species (ROS) significantly impacts the respiration chain enzymes and entirely the antioxidant system of mitochondria. Finally this may become a favorable condition for normal cells transformation.The purpose of the presented work was to study the mitochondrial defects and to establish their role in prostate cancer development.Results: Experimental results demonstrate significant increase of the activity of mitochondrial succinate dehydrogenaze (complex II) of the malignant epithelial cells of prostate, and slight changes in cytochrome oxydase (complex IV) activity. Also significant activation of the antioxidant system (glutathione-dependant system) of mitochondria in prostate malignant epithelial cells was revealed.Conclusion: The above mentioned mitochondrial changes (II and IV complexes of respiration chain, activity of the antioxidant system) partially demonstrate the alterations in mitochondrial energy metabolism, which from its side, may indicate to resistance of prostate cancer cells and correspondingly to intensification of proliferation processes.
Objectives: Fluorescence spectroscopy which can be used for optical tissue diagnosis of tumor pathology deserves special interest. The purpose of the work was to study blood plasma and tumor tissue of men with different forms of prostate tumors by using laser induced fluorescence. Blood plasma and tumor tissue of the patients with benign hyperplasia of the prostate (BHP), BHP with inflammation, BHP with high grade PIN (BHP with HGPIN) and adenocarcinoma of prostate (CaP) have been studied. Results: In case of blood plasma fluorescence, intensity of the plasma proteins corresponding peak (340-360 nm) was increasing in the following manner: control group → BHP → BHP with HGPIN → CaP. The intensity of the nicotinamide coenzymes correspond peak (440-460 nm) was increased in case of BHP with HGPIN and CaP patients, but decreased in case of BHP, compared to control. In case of tumor tissue, the changes of the collagen peak (390-400 nm) intensity have been revealed in all cases of prostate tumor tissues. These alterations point to altered collagen biosynthesis levels in different tumor tissues, that reflects the structural changes and characteristics of malignant transformation. Also the changes of the nicotinamide coenzymes peak (440-460 nm) intensity in all spectra of tumor tissues were observed. The highest intensity of the peak was observed in the spectra of BHP with HGPIN and in prostate cancer tissue. Conclusions: Alterations of the coenzymes peak intensities perfectly reflect and are in accordance with the specific energy metabolism of prostate epithelial cells. Normalization of fluorescent spectra from different forms of prostate tumor tissues has shown that, each form has typical spectral shape and ratio of fluorescence peaks intensities. L.

The significance of ABO blood system groups antigens in development of some malignant tumors is already established. The alteration of hormonal homeostasis must also be taken into account. Hence the aim of the investigation was to study ABO and Rh blood system antigens and hormonal status among reproductive age women with benign and malignant breast tumors. Methods: The determination of hormones was made by the enzymatic analysis method (ELAIZA), provided by proper ELAIZA kits. For the study of ABO and RhHr system antigens, internationally recognized immunoserology methods were used. Results: High index of the breast gland tumors were revealed in patients with A(II) phenotypic group, according to the ABO system. The frequency distribution of O(I) phenotypic group was low among women with breast tumors. Among D, C, E, c and e antigens of the Rh system, the frequency of D and E antigens were increased in benign and malignant breast tumors patients. The study of hormonal balance revealed thyroid gland hypofunction and increased level of estradiol on the background of increased testosterone and decreased progesterone levels. Such hormonal imbalance and excess production of estradiol creates conditions for malignant tumor formation in reproductive age women. Conclusion: The highest frequency of breast cancer in reproductive age was revealed in A(II) group patients. The wide spectrum of hormonal disorders were revealed in breast tumor patients of the reproductive age, which was especially clear in cases of malignant tumor.■ UDC: 616006 ■ Breast tumors ■ Blood group antigens ■ Rh system ■ Hormones
