The level of expression of anti-inflammatory cytokines NF-kB, IL-6, IFN-y, Caspasa-3, FC in chickens in the lungs and intestines during the modeling of infectious bronchitis in chickens was studied. To simulate coronavirus pneumonia, the vaccine was administered individually, 10 doses per head orally. The chickens of the 1st experimental group were fed with the Lyumantse preparation at the rate of 3 kg / t of feed, the 2nd experimental group received the Glitsevir drug at the rate of 200 μg / 0.3 ml per head. The chickens of the control group did not receive the preparations. It was revealed that antiviral drugs in the experimental groups suppressed the destruction of epithelial cells in the intestine. This may not always be an indication of a positive character, as in the case of apoptosis, not only the intestinal cells affected by the virus particles but also healthy cells are destroyed. There was a decrease in the number of active macrophages in the intestines of the experimental groups relative to the control. The amount of interferon produced was also below the control, which indicates a decreased activity of the immune system. A higher pro-inflammatory activity in the respiratory system of chickens was detected when Glicevir was used. It consists of increased expression of IL-6, interferon-gamma, macrophage receptor to Fc antibody fragments and inflammatory regulatory factor NF-kB genes compared to Lumantse with anti-inflammatory activity, but also compared to untreated control group chickens. It is concluded that it is possible to predict the risk of an exacerbation of an infectious process in the lungs against the background of a local decrease in the viral load in the intestine. An integrated approach is needed in the treatment of coronavirus infections, including either systemic antiviral drugs or anti-inflammatory drugs.

Este trabajo se fundamenta en la evaluación de la actividad antiinflamatoria de extractos de sofrito de tomate, así como de compuestos estándares de la dieta mediterránea, usando un modelo experimental optimizado basado en larvas de pez cebra. La migración de neutrófilos en larvas de pez cebra de 96 horas post fertilización se indujo mediante una lesión y se potenció añadiéndole lipopolisacárido, dicha migración se visualizó y cuantificó mediante análisis de imagen. El efecto antiinflamatorio del extracto de tomate y de los compuestos utilizados fue correlacionado porcentualmente por la disminución de la migración de los neutrófilos. Los resultados muestran que el extracto de tomate presentó una reducción en la migración de neutrófilos de 40 % respecto al grupo control. Por otra parte, el ácido clorogénico y la cianidina presentes en el sofrito de tomate utilizados como estándares presentaron una disminución de la migración de neutrófilos de un 66,7 % y 62,5 % respectivamente. Estos porcentajes son comparables a los resultados observados en ensayos con drogas antiinflamatorias como la indometacina y piroxicam. Los resultados muestran que el extracto de sofrito de tomate presenta posible actividad antinflamatoria demostrada por la reducción de la migración de neutrófilos, además el modelo se mostró sensible y válido para ser aplicado en matrices alimentarias complejas. The main of this study was to evaluate the anti-inflammatory activity of tomato sofrito extracts, as well as standard compounds present in the Mediterranean diet, using an optimized experimental model based on zebrafish larvae. Neutrophil migration in zebrafish larvae 96 hours post fertilization was induced by a cut in the caudal fin and enhanced by adding lipopolysaccharide and was visualized and quantified by image analysis. The anti-inflammatory effect of tomato extract and the compounds used was correlated by the percentage decrease in the migration of neutrophils. The results showed that, tomato extract showed a reduction in neutrophil migration of 40% compared to the control group. Moreover, chlorogenic acid and cyanidin present in tomato sofrito sauce showed a decrease in neutrophil migration of 66.7% and 62.5% respectively. These percentages are comparable to the results observed in trials with anti-inflammatory drugs such as indomethacin and piroxicam. The results show that tomato sofrito extract has possible anti-inflammatory activity demonstrated by the reduction of neutrophil migration, furthermore the model was sensitive and valid to be applied in complex food matrices.

Background: Nonsteroidal anti-inflammatory drugs such as diclofenac are used for relief of pain and inflammation, but frequently cause gastrointestinal complications. This study aimed to explore that combination of diclofenac and ?-tocopherol (áT) are better analgesic as well as anti-inflammatory agent than that of diclofenac alone.Objective: To assess the effects of combination of diclofenac with á-tocopherol on pain and inflammation.Methods: This prospective experimental study was conducted in the Department of Physiology, Bangabandhu Sheikh Mujib Medical University (BSMMU), Shahbag, Dhaka between January to December 2013. For this purpose, 15 male Long Evans rats were studied. On the basis of vitamin and drug administrations, the rats were divided into three (3) groups (5 rats in each). Control group received normal saline, one experimental group received diclofenac sodium (DS) at a dose of 10 mg/kg/body weight, and another experimental group received combination of DS with áT at a dose of 10 mg/kg/body weight and 500mg/kg/body weight, respectively. All the groups received single dose and equal volume (1 ml) through intraperitoneal route 1 hour before the test. Just one hour after administrations, they were subjected to formalin test followed by formalin induced paw edema test. The data were statistically analyzed by ANOVA followed by Bonferroni Post Hoc test.Results: Combined administration of DS and áT significantly (p<0.001) lowered the variables for nociceptive pain, central analgesic activity, inflammatory pain and inflammation than individual intervention of DS.Conclusion: From this study it may be concluded that, combined administration of diclofenac sodium and ±-tocopherol were more effective in lowering pain and inflammation than individual administration of diclofenac.Bangladesh Soc Physiol. 2015, June; 10(1): 30-35

Privileged Structures

Rheumatoid arthritis, arthrosis and gout, among other chronic inflammatory diseases are public health problems and represent major therapeutic challenges. Non-steroidal anti-inflammatory drugs (NSAIDs) are the most prescribed clinical treatments, despite their severe side effects and their exclusive action in improving symptoms, without effectively promoting the cure. However, recent advances in the fields of pharmacology, medicinal chemistry, and chemoinformatics have provided valuable information and opportunities for development of new anti-inflammatory drug candidates. For drug design and discovery, thiophene derivatives are privileged structures. Thiophene-based compounds, like the commercial drugs Tinoridine and Tiaprofenic acid, are known for their anti-inflammatory properties. The present review provides an update on the role of thiophene-based derivatives in inflammation. Studies on mechanisms of action, interactions with receptors (especially against cyclooxygenase (COX) and lipoxygenase (LOX)), and structure-activity relationships are also presented and discussed. The results demonstrate the importance of thiophene-based compounds as privileged structures for the design and discovery of novel anti-inflammatory agents. The studies reveal important structural characteristics. The presence of carboxylic acids, esters, amines, and amides, as well as methyl and methoxy groups, has been frequently described, and highlights the importance of these groups for anti-inflammatory activity and biological target recognition, especially for inhibition of COX and LOX enzymes.

Neuroinflammation is an integral part of epilepsy pathogenesis and other convulsive conditions, and non-steroidal anti-inflammatory drugs (NSAIDs) present a potent tool for the contemporary search and design of novel anticonvulsants. In the present paper, evaluation of the anticonvulsant activity of the potential NSAID dual COX-2/5-LOX inhibitor darbufelone methanesulfonate using an scPTZ model in mice in dose 100 mg/kg is reported. Darbufelone possesses anticonvulsant properties in the scPTZ model and presents interest for in-depth studies as a possible anticonvulsant multi-target agent with anti-inflammatory activity. The series of 4-thiazolidinone derivatives have been synthesized following the analogue-based drug design and hybrid-pharmacophore approach using a darbufelone matrix. The synthesized derivatives showed a significant protection level for animals in the scPTZ model and are promising compounds for the design of potential anticonvulsants with satisfactory drug-like parameters.

A significant role in the pathogenesis of peritonitis is attributed to free radical mechanisms of tissue damage. Due to inhibition of a number of membrane-bound enzymes and FRO of lipids of plasma membranes, foci of secondary necrosis appear in the peritoneum. Oxidized lipids have antigenic properties, and therefore stimulate autoimmune processes of tissue damage. In the pathogenesis of peritonitis, an important role is played by inflammatory mediators - cytokines. Their biological activity is manifested by the action on highly specific receptors located on cells. At the same time, interleukins and tumor necrosis factor act on all cells, exhibiting a systemic effect. It was found that the activity of ceruloplasmin in the blood plasma of patients in the control group progressively decreased from the first to the fifth day of the postoperative period, from 77.2 ± 5.61 to 59.32 ± 4.42 o.o. / g of protein, and in the patients of the experimental group it increased highly reliably - from 77.2 ± 5.61 to 97.31 ± 4.42 o.o. / h protein (p <0.001). The same pattern is characteristic of catalase activity. The activity of glutathione peroxidase in patients of both groups significantly decreased up to 3 days after the operation and increased on the fifth day, and it was more pronounced in the patients of the experimental group. When studying the level of cytokines, it was found that the expression of proinflammatory cytokines IL-1b, IL-8, TNFa exceeded the control values, while the expression of anti-inflammatory cytokines IL-1Ra was "delayed" (almost twofold). The highest expression of IL-1b, IL-8 potentiated further chain of pro-inflammatory reactions indicates the adequacy of the anti-inflammatory response and the relative balance between pro-inflammatory and anti-inflammatory cytokines and the adequacy of anticytokine therapy. The total number of septic complications (PBS) in the control group was 82.4%, and in the experimental group it was 66.7%. In dynamics study of pro- and antioxidant systems and serum concentra-tions of cytokine in the patients with acute peritonitis was high prognostic significance of results this study, which allows defining treatment tactic of these patients. To include in complex post-operative treatment of these pa-tients with evaluated antioxidant and anticytokine therapy allowed reducing the development of purulent-septic complications from 82.4 to 66.7%, which increased effectively of treatment in such patients and reduced the term of hospitality.

Inflammation is the response of living tissues to injury. The process affects physiological changes such as erythema, edema, asthma and fever. Non-steroid Anti-inflammatory Drugs (NSAIDs) have been developed since they could inhibit inflammation process because of its ability to inhibit biosynthesis of prostaglandin, one of inflammation mediators, through inhibition of cyclooxigenase (COX) enzymes. Molecules, which have been reported having anti-inflammatory activity, for example, are curcumin, some curcumin derivatives and curcumin analogues. One of curcumin analogues that has been  developed is pentagamavunon-0 (PGV-0) whose IUPAC name is 2,5-bis(4'-hidroxy-3'-methoxy-benzylidene)cyclo-pentanone. But PGV-0, which is like curcumin, practically insoluble in water, so it causes problems in the development. The aim of this research is to synthesize a derivative of PGV-0, a natrium salt of PGV-0 (natrium pentagamavunonate-0/Na-pentagamavunonate-0), which is hoped to have a better anti-inflammatory activity and solubility in water than PGV-0. PGV-0 was synthesized by reacting vanillin and cyclopentanone catalized by acid. Na-pentagamavunonate-0 was synthesized with PGV-0 as a starting material using an appropriate method. This research was able to synthesize new compound that was estimated as a natrium salt of PGV-0 (natrium pentagamavunonate-0/Na-pentagamavunonate-0).   Keywords: Curcumin, PGV-0, Na-pentagamavunonate-0, anti-inflammation

Aim. The article deals with developing and assessing the efficiency of a complex nutritional support program for the joint-ligament system in athletes and physically active people. Materials and methods. The clinical evidence of biologically active substance (BAS) efficiency and functional orientation was obtained from the representative group of people with knee-joint osteoarthrosis. The main group of participants received a BAS complex with synergistic properties in terms of metabolism correction during osteoarthrosis: BAS 1 – 2 pills, BAS 2 – 1 capsule (2 times per day, 12 weeks), and BAS 3 – 1 capsule (2 times per day, 8 weeks). Nonsteroidal anti-inflammatory drugs were also prescribed to participants from the main and control groups. We used the general and special methods for assessing the quality and functional properties of specialized products. Knee joints were studied by using the Lequesne index (scores) characterizing pain syndrome, maximal distance, and daily movement activity. The intensity of pain syndrome was assessed with the visual analog scale (VAS, in mm). Results. We provided a scientific justification for the qualitative and quantitative content of BAS recipes for complex nutritional support of the joint-ligament system: BAS 1 – chondroprotective orientation; BAS 2 – an optimal source of minerals and vitamins; BAS 3 – polyunsaturated fatty acids. The results obtained revealed that specialized products improve the movement activity of participants with osteoarthrosis and significantly decrease pain syndrome (36 %). Apart from a chondroprotective effect such nutrition provides an anti-inflammatory effect and allows decreasing the intake of Nonsteroidal anti-inflammatory drugs in the absence of side effects. We revealed an insignificant number of disease recurrence – 6.7% (in the control group – 36.5 %) and established the mechanisms of such an influence. Conclusion. The application of biologically active complexes could serve as a reliable means of preventing and treating the diseases of the joint-ligament system, providing physical performance, and preserving health in athletes and physically active people.
