At present, there are practically no studies deciphering the mechanisms of the possible influence of opportunistic pathogens on the morphological changes in the prostate gland. Many authors doubt that bacteria are the cause of chronic prostatitis. In clinical practice with prostate diseases preference is given to ultrasound examination as a reliable and time-consuming diagnostic test. At the same time, many authors note that for the diagnosis of inflammatory diseases of reproductive organs, the study of relevant secrets is an actual and promising scientific direction.The aim of the study was the investigation of qualitative and quantitative composition of microflora, a number of ejaculate proteins against the background of a different echoscopic picture of prostate.Materials and methods. The study included 18 men was in infertile couples for more than 3 years with a previously diagnosed chronic prostatitis (N41.1, observation group), and 28 healthy volunteers (comparison group). All participants in the study performed transrectal ultrasound. In the ejaculate, the concentrations of immunoglobulins of the main classes, total protein and albumin, as well as the level of oxidative modification of proteins were determined. Microbiological examination of the ejaculate was performed according to generally accepted methods. For statistical evaluation of the data obtained, an unpaired version of Student's t-test was used. Differences were considered statistically significant at p<0.05.Results. Microflora of the ejaculate in observation group was represented mainly by gram-positive cocci. In 39% of cases, the growth of Gram-negative microflora was established, from which Escherichia coli was isolated in 71% of the samples. In most samples, microorganisms were in the association, which is more typical for diffuse changes in prostate tissue. In cases with fibrosis, a noticeable narrowing of the spectrum of the released microflora was recorded: from Gram-negative bacteria only E. coli was isolated, and Gram-positive microorganisms were absent altogether. It was shown that the development of fibrosis in the prostate gland tissue is accompanied by an increase in the concentration of total protein and albumin in the ejaculate. When the process goes to the calcification stage, the levels of these indicators decrease. It was found that in all cases, with the exception of severe fibrosis, the concentration of IgG increases and IgA decreases. The development of fibrosis is accompanied by a decrease in the level of IgG. In the present study, in determining the level of oxidative modification of proteins, a decrease in the concentration of such molecules was found in patients of observation group.Discussion. In general, chronic inflammation in prostate of men of reproductive age in more than 60% of cases was characterized by fibrosis of the organ tissue and/or the formation of calcifications. In such situation, conditions are created for the persistence of opportunistic pathogenic microflora in fibro-modified tissue beyond the reach of immune system factors. In addition, there are phenomena of secondary immunodeficiency at the local level, manifested in a decrease in the number of leukocytes and their radical-producing function. That is why we consider the detection of conditionally pathogenic microorganisms as an essential fact of the pathogenesis of prostatitis, especially in the case of fibrosis and the formation of calcifications. Thus, the qualitative and quantitative study of microflora, the presence and degree of modification of the main protein components of the ejaculate, to a greater or lesser extent reacting to infectious inflammation, is primarily an asymptomatic one, broadens the concept of the pathogenesis of chronic prostatitis. As an addition to the ultrasound, its results allow us to clarify the duration of the inflammatory process, and to significantly decipher the echographic changes recorded at different stages of the development of the disease.

Introduction. Currently the chronic prostatitis (NIH type IV) remains insufciently studied and difcult to treat with antibiotics. When making the diferential diagnosis of chronic prostatitis it is generally accepted by the EAU   and Russian guidelines that the detected microorganisms in the prostatic fuid and the ejaculate practically do not difer from each other. The tactics of treating patients with asymptomatic prostatitis by means of antibacterial drugs remains disputable. Most reputable authors believe that this category of patients shall receive treatment in case   of infertility, pregnancy miscarriage or forthcoming surgery on the prostate gland. Recently, EAU guidelines have expressed doubts regarding the identity of the microbiota found in the prostatic secretions and the ejaculate.The study objective. Comparative analysis of the detectability of microorganisms in prostatic secretions and the ejaculate by means of bacteriological analysis among the men with chronic prostatitis of category IV.Materials and methods. The study involved 117 men who went to the urological clinic to pregravid examination or on the occasion of infertility. All patients were diagnosed with prostatitis of category IV based on a standard examination, and then a bacteriological analysis of prostatic secretions and ejaculate was performed. During the research the prostatic fuid and ejaculate were taken simultaneously and the analysis was carried out in one and the same bacteriological laboratory. In case the titer of the detected microorganisms was signifcant, the patients were ofered to undergo treatment without the use of antibiotics but with combination of bovhyaluronidase azoximer with prostate protectors and/or OM-89; after that a control bacteriological study was performed.Results. In the prostatic secretions and in the semen, the most commonly found gram-positive microorganisms were Staphylococcus spp. and Enterococcus spp.; the representatives of the Enterobacteriaceae were found less frequently. It was statistically proven that the titer of bacteria in the prostatic secretions was considerably higher than that in the ejaculate (p <0.01). Sterile cultures were statistically-proven to be more frequent in ejaculate compared with prostatic secretions (13.7 % vs 3.4 %, p <0.01). When analyzing the coincidences for bacteria, low concordance was obtained for all identifed microorganisms (gram-positive bacteria varied from 48.3 to 79.5 %, gram-negative bacteria varied from 57.1 to 80.0 %). After the combined therapy, the bacterial mass signifcantly decreased in the prostate secretion from 104.3 ± 1.6  CFU/ml to 103.3 ± 2.0 CFU/ml (p = 0.008), while in the semen the bacterial mass decreased from 103.5 ± 1.8 CFU/ml to 102.6 ± 2.1 CFU/ml (p = 0.02). In the prostatic secretions, there was a statistically-proven decrease in the number of gram-negative bacteria (p = 0.05). As soon as the treatment was completed all the patients demonstrated the normalized number of leukocytes according to microscopy of prostate secretions or spermogram.Conclusion. The ejaculate is a more sterile biomaterial compared with the prostatic fuid, which should be taken into account in the diferential diagnostics of the chronic prostatitis of category IV and MAGI. The use of non-antibacterial treatment regimens, such as bovhyaluronidase azoximer, prostate protectors and OM-89, can reduce the titer of bacteria to insignifcant values both in the prostatic secretions and in the semen; and in some cases make the ejaculate sterile.

Alkaline water is in the focus of scientific interest over the last decade, due to its ability to alkalize the organism as well as its antioxidant effect. The aim of our research is to determine the impact of ionized water by adding enzymatic and non-enzymatic antioxidants, glutathione and vitamin C, during hyperthermic stress, on the concentration of total proteins. The experiment performed on a white laboratory Wistar rats, a female sex, weighing 180-220 g, young rats, divided into three groups of 15 individuals. Oxidative stress was caused by acute hyperthermic exposure at 41˚C. The first group is the control group (KPM), the second group is treated with ionized water (TAM), and the third group with ionized water with added glutathione and vitamin C (TAD). The duration of treatment lasted 21 days. Acute hyperthermic exposure caused a significant difference in total protein concentration between the 7th and 14th day taken as the starting points and the 21st day of treatment, respectively, on the day of hyperthermic exposure of rats. Such a significant difference was observed in the KPM and the TAM group (p <0.001), whereas the TAD group is an exception where no statistically significant difference was observed in the same period (p> 0.05). Animals treated with ionized water on day 14 showed a significantly higher total protein concentration (p <0.01) compared to the group receiving only natural water, which is consistent with the finding obtained by comparison between the KPM and TAD group at 21st day where the difference is also statistically significant (p <0.05). The acute application of the treatment with ionized water, without or in combination with other antioxidants, in the absence of hyperthermic stress does not lead to a significant alteration in protein concentration. The hyperthermic exposure intensifies the production of oxygen radicals and the potential for oxidative modification of proteins and molecules with a protein structure. Individual action of ionized water as well as synergism with the added antioxidants caused a high protective effect on oxidative damage. Because of this, the effect of oxidative cleavage is less pronounced in rats treated with ionized water and antioxidants because they have a stronger antioxidant defense that prevents oxidative modification of proteins and all biomolecules in the body.

Periplasm of bacteria is the space outside the permeability barrier of plasma membrane but enclosed by the cell wall. The contents of this special milieu exterior could be regulated by the plasma membrane from the internal, and by the cell wall from the external environment of the cell. Unlike the gram-negative organism, the presence of this space in gram-positive bacteria is still controversial because it cannot be clearly demonstrated. We have shown the importance of some periplasmic bodies in the secretion of penicillinase from Bacillus licheniformis.In negatively stained specimens prepared by a modified technique (Figs. 1 and 2), periplasmic space (PS) contained two kinds of structures: (i) fibrils (F, 100 Å) running perpendicular to the cell wall from the protoplast and (ii) an array of vesicles of various sizes (V), which seem to have evaginated from the protoplast.

Blood cultures are positive in approximately only 50 per cent of the patients with nongonococcal bacterial infectious arthritis and about 20 per cent of those with gonococcal arthritis. But the concept that gram-negative bacteria could be involved even in chronic arthritis is well-supported. Gram stains are more definitive in staphylococcal arthritis caused by gram-positive bacteria than in bacterial arthritis due to gram-negative bacteria. In the latter situation where gram-negative bacilli are the problem, Gram stains are helpful for 50% of the patients; they are only helpful for 25% of the patients, however, where gram-negative gonococci are the problem. In arthritis due to gram-positive Staphylococci. Gramstained smears are positive for 75% of the patients.

AbstractOur interest has focused on the investigation of the anti-obese potential of kidney beans (P. vulgaris) pods extract. In the course of the study, obesity development in rats was induced with high-calorie diet. Control and obese rats then have consumed with aqueous kidney beans (P. vulgaris) pods extract during 6 weeks (200 mg/kg). Results show that the long-term consumption of P. vulgaris pods extract can lead to the reduction of hyperglycemia and insulin resistance development. Furthermore, we saw a normalization of lipid peroxidation parameters and oxidative modification of protein due to the consumption of the kidney beans (P. vulgaris) pods extract. Our experimental data demonstrate the ability of the kidney beans (P. vulgaris) pod extracts to mitigate obesity development but the details of this mechanism remains to be not fully understood.

magnesium oxide nanoparticles (MgO NPs) were prepared by simple wet chemical method using different calcination temperatures. The prepared NPs were characterized by Electrostatic Discharge (ESD), Scanning Electron Microscope (SEM) and X-ray Diffraction (XRD). It demonstrates sharp intensive peak with the increase of crystallinty and increase of the size with varying morphologies with respect to increase of calcination temperature. Antibacterial studies were done on gram negative bacteria (E.coli) and gram positive bacteria (S.aureus) by agar disc diffusion method. The zones of inhibitions were found larger for gram positive bacteria than gram negative bacteria, this mean, antibacterial MgO NPs activity more active on gram positive bacteria than gram negative bacteria because of the structural differences. It was found that antibacterial activity of MgO NPs was found it has directly proportional with their concentration.

Antimicrobial resistance (AMR) has become one of the more serious threats to the global health. The emergence of bacteria resistant to antimicrobial substances decreases the potencies of current antibiotics. Consequently, there is an urgent and growing need for the developing of new classes of antibiotics. Three prepared novel iron complexes have a broad-spectrum antimicrobial activity with minimum bactericidal concentration (MBC) values ranging from 3.5 to 10 mM and 3.5 to 40 mM against Gram-positive and Gram-negative bacteria with antimicrobial resistance phenotype, respectively. Time-kill studies and quantification of the extracellular DNA confirmed the bacteriolytic mode of action of the iron-halide compounds. Additionally, the novel complexes showed significant antibiofilm activity against the tested pathogenic bacterial strains at concentrations lower than the MBC. The cytotoxic effect of the complexes on different mammalian cell lines show sub-cytotoxic values at concentrations lower than the minimum bactericidal concentrations.
