Background. Root canal treatment is a main role in decreasing infection from root canal and pulp. The main cause of periapical damage mostly are bacteries. E.faecalis is a bactery that is found as an etiology of endodontic treatment failure. Cell wall of this bacteria is containing Lipoteichoic acid (LTA). LTA can penetrate into the periradicular tissue, act as endotoxin in host and cause periradicular inflammation then lead to bone destruction. LTA stimulates immunology reaction that produce Tumor Necrosis Factor alpha (TNF-α) and Transforming growth factors beta (TGF-ß). TNF-α is a main mediator and also have an important role in inflamation response otherwise TGF-ß is working as a multifunction  regulator of cell growth and differentiation during reforming and remodelling.  Purpose. The aim of this study is to know about the expression of TNF-α and TGF-ß during the periapical tissue damage due to induction of E.faecalis. Method. This study used laboratory experimental with the post test only control group design. A total of 30 male rats were randomly divided into 3 main groups, Group A (control negative) : normal tooth. Group B (control positive) : every tooth was induced only by sterile BHI-b. Group C (treated group) : every tooth  was induced by 10 μl BHI-b E.faecalis ATCC212(106 CFU). The animals were sacrificed 21 days later and prepared for histological examination of tissue damage, then we did the immunohistochemistry  followed by calculation on the light microscope. Result. The analysis revealed that the expression of TNF-α at treated group are higher than negative control and positive control but the expression of  TGF-ß at treated group are higher than the negative control group but lower than positive control. Conclusion. From this study we know that the expression of TNF-α and TGF-ß are changing during the periapical tissue damage that induced by E.faecalis.

ABSTRACT: Objectives: This study aimed to determine the effects of propolis on immune mediators and tissue histopathology in rats with L-arginine-induced acute pancreatitis (AP). Methods: This study was conducted at Imam Abdulrahman Bin Faisal University, Dammam, Saudia Arabia between September and November 2017. A total of 24 male albino Wistar rats were divided into three equal groups. Group one was the negative control, group two was the positive control (L-arginine-induced AP) and group three received treatment (L-arginineinduced AP and propolis). The rats in group three were treated with 100 mg/kg propolis for seven days after AP induction. Pancreatic tissue was evaluated histologically and levels of interleukin (IL)-6, IL-22 and IL-1β and tumour necrosis factor-alpha (TNF-α) were measured. Results: Propolis reduced the quanitity of proinflammatory molecules (TNF-α, IL-1β and IL-6) in group three compared to group two, significantly increased the overall anti-inflammatory effect of IL-22 (P <0.005) and reduced interstitial inflammation and neutrophil cell infiltration of the pancreatic tissues. Conclusion: Propolis may exert a therapeutic effect in AP. Further studies are required to demonstrate the mechanisms of propolis in AP.Keywords: Propolis; Arginine; Pancreatitis; Interleukins; Cytokinesis; Rats; Saudi Arabia.

Purpose: Accumulating evidence shows the genus of Sambucus exerts a broad spectrum ofmedicinal potencies such as anticancer, antiviral, antibacterial, and antidiabetes. Based on theprevious studies, we hypothesized that bioactive compounds of Sambucus might alter severalbiological systems, including the immune system. Therefore, this study extensively aimed toevaluate the immunomodulatory activities of Sambucus javanica extracts in 7,12-dimethylbenz[a]anthracene (DMBA)-treated BALB/c mouse.Methods: The experimental mice were orally administrated with 2.8 mg.kg-1 BW of DMBA forten times within a month. After that, the mice were treated by S. javanica berries and leavesextracts for 2 weeks. Subsequently, the inflammation rate was evaluated by using flow cytometryanalysis, whereas the necrosis incidences were observed by hematoxylin & eosin staining.Results: Based on the results, we found the expression of tumor necrosis factor alpha (TNF-α)and interferon gamma (IFN-ɣ) were increased however after treated by S. javanica berries andleaves extracts were significantly decreased. In the same way, necrosis incidence was increasedin the DMBA-treated group however it was diminished with S. javanica extracts treatment.Conclusion: Together, these results suggested that S. javanica extracts have immunomodulatoryactivities to suppress inflammation and reduce necrosis incidence in experimental mice.<br />

Inflammatory mediators have an important role in the pathogenesis of periodontal disease. One of the leading mediators of the initiation of the pathological process is interleukin-1 (IL-1) – an endogenous pyrogen, a lymphocyte-activating factor. Numerous pro-inflammatory effects of interleukin-1β (IL-1β) occur in synergy with tumor necrosis factor alpha (TNF-α) and interleukin-6 (IL-6), effects on hematopoiesis, participates in nonspecific anti-infective defense.The objective of the study is to determine levels of interleukin-6 and tumor necrosis factor alpha (TNF-α) in patients with hypertension II stage and generalized periodontitis of the II degree depending on the treatment method.There were examined 30 patients with hypertension of the II stage and with generalized periodontitis of the II degree. Patients’ age ranged from 35 to 54 years. These patients were divided into two groups. The control group included 10 patients without general somatic pathology and with healthy periodontitis of the same age. The result of the analysis of tumor necrosis factor alpha (TNF-α) in patients in the first group before the treatment was 10.69±2.33 pg/ml. After the treatment this indicator was 6.97±1.57 pg/ml (p>0.1) in patients of the first group.In patients of the second group the tumor necrosis factor alpha (TNF-α) was 9.49±2.2 pg/ml; after the treatment according to the offered scheme this figure decreased up to 2.77±0.9 pg/ml (p<0.01). The level of tumor necrosis factor alpha (TNF-α) in the control group was 1.5±0.77 pg/ml.Interleukin-6 was 9.91±2.04 pg/ml before the treatment in the first group. After the treatment according to the standard scheme, the level of interleukin-6 was 6.33±0.97 pg/ml (p>0.1). In the second group, before the treatment the level of  interleukin-6 was 9.65±2.41 pg/ml; after the treatment according to the offered scheme it was 2.62±0.5 pg/ml (p<0.01). In the control group the interleukin-6 level was 2.24±0.51 pg/ml.Analyzing the obtained results after the treatment in both groups we can conclude: after the treatment of generalized periodontitis of the II degree in patients with hypertension of the II stage, indices of pro-inflammatory cytokines decreased and ranged in normal limits; in patients from the second group (who received the offered scheme of treatment -including medicines) indexes of pro-inflammatory cytokines were significantly lower than in patients with the standard treatment scheme; the proposed scheme of treatment is more effective for treatment patients with generalized periodontitis of the II degree and hypertension of the II stage.

The emergence of the novel coronavirus and then pandemic outbreak was coined 2019- nCoV or COVID-19 (or SARS-CoV-2 disease 2019). This disease has a mortality rate of about 3·7 percent, and successful therapy is desperately needed to combat it. The exact cellular mechanisms of COVID-19 need to be illustrated in detail. This study aimed to evaluate serum cytokines in COVID-19 patients. In this study, serum was collected from volunteer individuals, moderate COVID-19 patients, severe cases of COVID-19 patients, and patients who recovered from COVID-19 (n = 122). The serum concentrations of interleukins such as IL-1, IL-4, IL-6, IL-8, IL-10, and tumor necrosis factor-alpha (TNF-α), were measured by enzyme-linked immunosorbent assays (ELISA). The concentrations of IL-1 and TNF-α were did not differ significantly among groups. However, the concentration of IL-6 was significantly higher in moderate COVID-19 and severe cases of COVID-19 groups compared to control and recovered groups indicating it to be an independent predictor in the coronavirus disease. The levels of IFN-γ and IL-4 were significantly lower in the recovery group than the severe case of the COVID-19 group. In contrast, the level of IL-10 in recovered COVID-19 patients was significantly higher in compare to severe cases, COVID-19 patients. Varying levels of cytokines were detected in COVID-19 group than control group suggesting distinct immunoregulatory mechanisms involved in COVID-19 pathogenesis. However, additional investigations are needed to be to be performed to understand the exact cellular mechanism of this disease.

Preeclampsia is a pregnancy-specific syndrome that may be dangerous especially to the fetus. Different cytokines have been found to be elevated in women with preeclampsia and may have possible roles in the development of this disorder. Alleles of the interleukin-6 (IL-6) and tumor necrosis factor alpha (TNF-α) genes are associated with preeclampsia in several studies in different populations. The aim of the present study was to investigate the relationship between IL-6 (G174C) and TNF-α (G-308A) gene polymorphisms with preeclampsia in North Coastal Andhra Pradesh of India. The TNFA (-308 A/G) and IL6 (-674G/C) genotypes were determined in 100 preeclamptic women and 100 normal pregnant women as control group, using allele-specific oligonucleotides-polymerase chain reaction method. Data was analyzed using chi-square and Fisher’s exact tests. TNF-α (G-308A) G/G genotype showed a significantly higher frequency among the preeclamptic group than the control group (odds ratio, 0.4603, 95% confidence interval, (0.2521- 0.8405); P = .005). G/A genotype also showed higher frequency among the preeclamptic group compared to control group (odds ratio, 2.508, 95% confidence interval, ((1.341-4.689); P = .001). IL-6 (G174C) genotype significantly higher frequency among the preeclamptic group than the control group (odds ratio, 0.4603, 95% confidence interval, (0.2521- 0.8405); P = .005).  The present study might suggest a role for TNF-α (G-308A) and -174 GC of IL-6 genotype in the development of preeclampsia; suggesting that they are of differing genetic predisposition/pathophysiology.

Abstract Introduction An important open question in the literature is whether endometrial receptivity marker levels are different in infertility related diseases than healthy women. The aim of the study is to compare the levels of interleukin two (IL-2) and tumor necrosis factor alpha (TNF-α) during the implantation window in the endometrial flushing fluid of polycystic ovary syndrome (PCOS), endometrioma, leiomyoma patients with healthy controls. Material and Methods In this case control study, after obtaining endometrial flushing fluids at mid-luteal phase of ovulatory women with PCOS (n = 20), endometrioma (n = 19), leiomyoma (n = 20) and healthy controls (n = 20), IL-2 and TNF-α levels were measured using ELISA kits in BioTek ELISA devices. Results Mean TNF-α levels (ng/mL) were similar for the PCOS (305.6, p = 0.220) and the leiomyoma group (246.3, p = 0.502) compared to healthy patients (261.1). However, the levels were higher in the endometrioma group (338.2, p = 0,004) than the control group (261.1) in a statistically significant way. Mean IL-2 levels (ng/mL) were significantly lower in the PCOS (290.9, p = 0.0005), the leiomyoma (282.9, p = 0.0002) and the endometrioma patients (229.5, p = 0.0009) than the control group (416.0). Conclusion Relative to the control group, endometrial flushing fluid TNF-α levels were significantly higher in endometrioma patients and IL-2 levels were significantly lower in PCOS, leiomyoma and endometrioma patients. In benign gynecological diseases, endometrial markers related to infertility seem to show differences in endometrial flushing fluid. Future studies might identify the reference values for these markers, and endometrial markers can be used to diagnose gynecologic disorders causing infertility.

Urinary tract infections may induce severe inflammation, transient impairment in renal function and scar formation, ranging in severity from acute symptomatic pyelonephritis to chronic pyelonephritis, and have the potential to lead to renal failure and death. In the present study, the relationship between production of tumour necrosis factor-alpha (TNF-α), interleukin-1beta (IL-1β), neutrophil recruitment, bacterial colonization and tissue damage was investigated using a mouse model of acute ascending pyelonephritis induced with planktonic and biofilm cells ofPseudomonas aeruginosa. Neutrophil influx correlated with rise in TNF-α and IL-1β, indicating an association between these cytokines and neutrophil infiltration. However, biofilm cells ofP aeruginosainduced higher levels of TNF-α and IL-1β leading to higher neutrophil infiltration causing tissue damage, assessed in terms of malondialdehyde, lactate dehydrogenase and glutathione content, which may have contributed to bacterial persistence compared with their planktonic counterparts. The results of the present investigation suggest that exaggerated cytokine production duringP aeruginosa-induced pyelonephritis causes tissue damage operative through neutrophil recruitment leading to bacterial persistence in host tissues. The findings of the present study may be relevant for the better understanding of disease pathophysiology and for the future developments of preventive strategies against pyelonephritis based on anti-inflammatory intervention.

The present study was designed to assess the stress responses to a simulation model of the undersea environment that is similar to some undersea working conditions such as submarine rescue, underwater salvage and underwater construction. Restraint, hyperbaric air and immersion were chosen to produce the simulation stress model in rats for four hours. Rats were randomized into five groups: control group, restraint (R) group, hyperbaric air (H) group, restraint plus hyperbaric air (RH) group, and restraint plus hyperbaric air plus immersion (RHI) group. The results showed that the responses to the simulation stress model of the undersea environment induced by R, H, RH and RHI involved the upregulated norepinephrine (NE), dopamine (DA) and 5-hydroxytryptamine (5-HT) of the central nervous system (CNS), upregulated adrenocorticotropic hormone (ACTH), corticosterone (CORT) and blood glucose of the neuroendocrine system, upregulated interleukin-1 (IL-1), interleukin-6 (IL-6) and tumor necrosis factor alpha (TNF-α) of the immune system, and increased anxiety in rats. Compared with hyperbaric air, restraint tended to activate stronger stress responses. Conclusively, this work established a simulation stress model of the undersea environment induced by restraint, hyperbaric air and immersion. It further provided experimental data of such a model that showed significant activation of the CNS, neuroendocrine and immune systems and anxiety in rats. In this experiment we provided an experimental basis for undersea work such as working aboard a submarine.

Objective: The objective of the study was to determine the severity level of keratitis, inflammatory response, and clinical feature of fungal keratitis associated with tumor necrosis factor-alpha (TNF-α) and matrix metalloproteinase (MMP)-9 expression, with and without steroid administration. Methods: The mice corneas were inoculated with 108 CFU Candida albicans (CA), divided into two groups, one group with steroid administration and other group without steroid, and uninoculated cornea is used as the control. The mice eyes were observed for the development of keratitis and assess the clinical score to categorize severity level of the keratitis. After 7 days, they were enucleated for analysis of TNF-α and MMP-9 expression with immunohistochemistry and histopathologic examination. Results: Results show that the group inoculated with Candida and steroid has more moderate and severe level of keratitis compared to the group inoculated with Candida only. The final clinical score in the group of CA injected with steroid was 5–12 with mean 8.89 (2.67). The histopathological examination confirmed the presence of prominent inflammatory response in steroid group. The mean of TNF-α expression in Candida keratitis with and without steroid injections is 50.1 (8.09) and 31.7 (6.89) consecutively, compared to 16.8 (1.58) of control group. The mean of MMP-9 expression in Candida keratitis with steroid injection is higher than Candida keratitis group without steroid injection and control group, which are 46.6 (4.3), 37.8 (4.96), and 17.2 (1.73), respectively. This difference is statistically significant. Conclusion: Administration of steroids to Candida keratitis has negative effect to corneal tissue, resulting in more severe inflammatory response associated with increased TNF-α and MMP-9 expressions.

 Objective: The aim of this study was to investigate the effects of the short-term use of a probiotic milk drink on salivary tumor necrosis factor-alpha (TNF-α) in children with acute lymphoblastic leukemia (ALL) during the induction phase of chemotherapy.Methods: A randomized, case-controlled clinical trial was carried out. The samples of the study were collected from 11 children with ALL and 11 healthy children as the control. Both groups received a probiotic milk drink. The probiotic milk drink contained Lactobacillus casei (6.5×109 colony forming unit/mL). The subjects were instructed to rinse 5 mL of probiotic milk drink for 30 s over the course of 2 weeks. Unstimulated saliva samples were collected from patients at baseline and 1 and 2 weeks after rinsing with the probiotic milk drink. The levels of TNF-α were determined using a human TNF-α enzyme-linked immunosorbent assay kit.Results: The salivary TNF-α levels in the experimental group decreased but not to a statistically significant degree (p>0.05) when comparing the baseline with weeks 1 and 2 after rinsing. There was a significant decrease of salivary TNF-α levels in the control group (p<0.05) when comparing the baseline with 1 and 2 weeks after rinsing. The concentration of salivary TNF-α in the experimental group was higher than in the control group (p<0.05).Conclusion: This study demonstrates the effect of a short-term intake of a probiotic milk drink on children with ALL during the induction phase of chemotherapy. The results show a reduction of salivary TNF-α after taking the probiotic milk drink after 1 week and 2 weeks, although the results were not statistically significant.
