Summary. The aim was to identify the features of the lacrimal fluid cytokine profile in patients with bacterial keratitis of the II degree of severity and type 1 DM in the dynamics of observation. Materials and methods. The lacrimal fluid cytokine profile was analyzed in 6 patients with type 1 DM and bacterial keratitis of the II degree of severity and 6 nondiabetic patients with bacterial keratitis of the II degree of severity on the 1st day, 10-14th day and 24th day of observation. Data from 14 healthy individuals of the appropriate age were used for comparison. II degree of severity of bacterial keratitis was determined according to our proposed scheme at a sum of points 15-21. All patients were treated with instillations of ofloxacin, antiseptics, antioxidants, reparents, artificial tears, mydriatics, systemic anti-inflammatory therapy. The concentration of interleukins (IL)-1β, IL-6 and IL-10 in the lacrimal fluid of the sick and the contralateral eye was determined by quantitative colorimetric enzyme-linked immunosorbent assay using ELISA kits. Results and discussion. In patients with bacterial keratitis of the II degree of severity, both with DM and nondiabetic, within 10-14 days of observation invented the expression of proinflammatory cytokines IL-1β and IL-6 in the lacrimal fluid of the sick eye and anti-inflammatory cytokine IL-10 - in lacrimal fluid of the contralateral eye (p<0.05). In DM patients, a longer expression of IL-1β and IL-6 was detected in the lacrimal fluid of the sick and the contralateral eye, which was observed on the 24th day of the study (p<0.05). Conclusions. There are features of the lacrimal fluid cytokine profile in DM patients with bacterial keratitis of the II severity in the dynamics of observation, namely the longer expression of proinflammatory cytokines IL-1β, IL-6 in the sick and the contralateral eye.

Summary. In patients with diabetes mellitus (DM) there are features of the dynamics of the I degree severity bacterial keratitis, leading to prolongation of the disease and worsening of its consequences. The aim was to identify immunological features of the dynamics of the I degree severity bacterial keratitis depending on the presence of type 1 DM. Materials and methods. The level of interleukins (IL) was analyzed, namely IL-1β, IL-6 and IL-10 in the lacrimal fluid of the sick and the contralateral eye of 6 patients with type 1 DM and the I degree severity bacterial keratitis and 6 nondiabetic patients with I degree severity bacterial keratitis on the 1st day, 10-14th day and 24th day of observation. Data from 14 healthy individuals of the appropriate age were used for comparison. The severity of bacterial keratitis was determined according to our scheme at a total score of ≤ 14. All patients were treated with instillations of ofloxacin, antiseptics, antioxidants, reparents, artificial tears, mydriatics, systemic anti-inflammatory therapy. The level of IL in the lacrimal fluid was determined by quantitative colorimetric enzyme-linked immunosorbent assay using ELISA kits by ANOGEN according to the instructions for use. Results and discussion. In patients with I degree severity bacterial keratitis, both DM and nondiabetic, on the 1st day of observation there was an increase in the level of IL-1β and IL-6 in the lacrimal fluid of the sick eye and IL-10 – of the contralateral eye compared to healthy persons, on the 10th-14th day — increase in the level of IL-1β and IL-6 of the sick and the contralateral eye, as well as IL-10 – of the contralateral eye (p<0.05). On the 24th day in nondiabetic patients with I degree severity bacterial keratitis normalization of interleukin levels in the lacrimal fluid of the sick and the contralateral eye was found, but in DM patients remained elevated levels of IL-1β, IL-6, both in the sick and in the contralateral eye (p<0.05). Conclusions. In DM patients there are immunological features of the dynamics of the I degree severity bacterial keratitis, namely a longer increase in the level of proinflammatory cytokines IL-1β, IL-6 in the lacrimal fluid of the sick and the contralateral eye.

Cytokine- and chemokine-mediated signalling is involved in the neuroinflammatory process that leads to retinal ganglion cell (RGC) damage in glaucoma. Substances with anti-inflammatory properties could decrease these cytokines and chemokines and thus prevent RGC death. The authors of this study analysed the anti-inflammatory effect of a hydrophilic saffron extract standardized to 3% crocin content, focusing on the regulation of cytokine and chemokine production, in a mouse model of unilateral laser-induced ocular hypertension (OHT). We demonstrated that following saffron treatment, most of the concentration of proinflammatory cytokines (IL-1β, IFN-γ, TNF-α, and IL-17), anti-inflammatory cytokines (IL-4 and IL-10), Brain-derived Neurotrophic Factor (BDNF), Vascular Endothelial Growth Factor (VEGF), and fractalkine were unaffected in response to laser-induced OHT in both the OHT eye and its contralateral eye. Only IL-6 levels were significantly increased in the OHT eye one day after laser induction compared with the control group. These results differed from those observed in animals subjected to unilateral OHT and not treated with saffron, where changes in cytokine levels occurred in both eyes. Therefore, saffron extract regulates the production of proinflammatory cytokines, VEGF, and fractalkine induced by increasing intraocular pressure (IOP), protecting the retina from inflammation. These results indicate that saffron could be beneficial in glaucoma by helping to reduce the inflammatory process.

ABSTRACT Campylobacter jejuni is a major cause of diarrhea in humans. A mouse lung model of infection was previously established for C. jejuni. We used this model to study cytokine production in the lungs and correlated it with pathological changes. C. jejuni strain 81-176 or sterile phosphate-buffered saline was intranasally inoculated into adult BALB/c mice. The levels of proinflammatory cytokines (gamma interferon, tumor necrosis factor alpha, interleukin-1β [IL-1β], IL-2) and anti-inflammatory cytokines (IL-4, IL-10), in addition to those of IL-6, were assessed on days 1, 3, and 5 postinfection by enzyme-linked immunosorbent assay, and the ratios of proinflammatory cytokines to anti-inflammatory cytokines were calculated. Since IL-6 is unique in that it is both a proinflammatory cytokine and a TH2 cytokine, it was considered to be both in the determination of these ratios. The significance of the cytokine levels and ratios were determined by the Mann-Whitney U test (P ≤ 0.05). The induction of proinflammatory cytokines in the lungs of infected mice, as indicated by the cytokine levels and ratios, coincided with the accumulation of neutrophils and activated macrophages, in addition to the clearance of the bacterial load and bacteriumlike structures that we have previously shown in the same groups of mice. This was followed by increased levels of anti-inflammatory cytokines and the resolution of inflammation and pathology in the lungs. This study demonstrates the dynamics of cytokine production and their correlation with tissue inflammation and the resolution of infection. This model is useful for further studies of the pathogenesis of C. jejuni infection and vaccine evaluation.

Background. It has now been established that inflammatory cytokines are involved in all the stages of the development of coronary heart disease. It has been scientifically proved that the severity of coronary heart disease directly correlates with the increase in the level of proinflammatory cytokines, while data on the role of proinflammatory interleukin IL-8 and anti-inflammatory interleukin IL-4 are contradictory. The aim of the study was to evaluate the levels of proinflammatory cytokines (IL-8, TNF-) and anti-inflammatory interleukin (IL-4) in patients with various forms of coronary heart disease who underwent re-stenting of the coronary arteries. Materials and methods. By the method of enzyme-linked immunosorbent assay, the levels of cytokines were determined in 28 patients who had previously undergone myocardial infarction with stenting of an infarct-related artery, re-admitted due to the development of acute coronary syndrome, who underwent repeated stenting of coronary arteries. The same method was performed on 24 patients who also had previously undergone myocardial infarction with stenting of the infarction-associated artery, who were admitted to the clinic for staged stenting of the coronary arteries. Results. In patients with chronic coronary syndrome the levels of IL-4 a do not exceed the reference values, in patients with acute coronary syndrome the levels of IL-4 there was an increase 3,700,24 and 359,8066,94 pg/ml, р 0,001. In patients with chronic coronary syndrome the levels of IL-8 a do not exceed the reference values, in patients with acute coronary syndrome the levels of IL-8 there was an increase 7,341,29 and 69,7518,25 pg/ml, р 0,001. Conclusions. The increase in the level of IL-4 has a compensatory character and, along with a slight increase in TNF-, can be considered as a positive factor stabilizing the course of the disease.

Objective — improvement of methods of treatment of chronic generalized periodontitis based on the analysis of the cytokine profile of patients. Methodology. A study of 120 patients with chronic periodontitis of varying severity aged 30 to 50 years was conducted. All patients were randomized into 5 groups according to the severity of the disease and therapy. all patients received traditional anti-inflammatory therapy. In group 4, in addition to the main treatment, patients received laser therapy sessions. In group 5, patients with severe chronic periodontitis were administered remaxol along with laser therapy. Evaluation of the condition of periodontal tissues was carried out according to clinical indices. PMA, SBI, API, OHI-s, and periodontal indices were used. The serum levels of IL-1β, IL-2, IL-4, IL-6, IL-8, IL-10, IFN-γ, and TNF-α were studied by enzyme immunoassay. Results: In chronic generalized periodontitis of moderate and severe severity, the content of all studied proinflammatory cytokines in the blood serum increases, and more significantly in the group of patients with severe disease. At the same time, the content of anti-inflammatory mediators undergoes ambiguous changes: in group I, the content of IL-4 increases significantly, and in group II it does not change significantly. In turn, IL-10 in group I does not decrease significantly, but in group II it becomes significantly less than normal. The inclusion of laser therapy and remaxol in the complex of standard measures showed high efficiency in reducing the severity of the pathological process, which was expressed in a faster subsiding of inflammatory phenomena in periodontal tissues. Conclusions: An increase in the content of proinflammatory cytokines in the blood serum in chronic generalized periodontitis was revealed, and more significantly in the group of patients with a severe course of the disease. At the same time, an imbalance of the system of pro-inflammatory and anti-inflammatory cytokines is registered. The use of laser therapy and remaxol in the complex treatment of CPT was the most effective.

Purpose: To investigate the potential anti-inflammatory effects of the seeds of Opuntina humifusa and its active constituents.Methods: The extract of O. humifusa seeds was tested for the inhibition of nitric oxide (NO) production in liposaccharide (LPS)-stimulated RAW 264.7 cells using Griess reagent. The active constituents were isolated using bioassay-guided isolation methods. The effects of the active constituent on NO, proinflammatory cytokines, nuclear factor-kappa B (NF-κB) and nuclear factor of kappa light polypeptide gene enhancer in B-cells inhibitor (IκB) were evaluated by enzyme-linked immunosorbent assay (ELISA) and western blot analysis.Results: The seed extract of O. humifusa significantly attenuated LPS-induced NO production in RAW 264.7 cells (p < 0.05). Bioassay-guided fractionation resulted in the isolation of isoamericanin A as an active constituent. Isoamericanin A reduced LPS-induced production of NO, iNOS, and proinflammatory cytokines (TNF-α and IL-6) in a concentration-dependent manner (p < 0.05). Furthermore, the effect was accompanied by decreased translocation of NF-κB from the cytosol to the nucleus and the decreased phosphorylation of IκB in the cytosol induced by LPS (p < 0.05).Conclusion: The seed extract of O. humifusa and its active constituent, isoamericanin A, have antiinflammatory effects in LPS-stimulated RAW 264.7 cells, suggesting that they have potentials as antiinflammatory agents. Keywords: Opuntia humifusa seeds, Isoamericanin A, Nitric oxide, RAW 264.7 cells, NF-kappa B
