Etlingera alba is one of the Etlingera plants that has not been studied intensively. Plants that belong to the same genus have similar constituents and pharmacological activities. Thus, we aim to investigate the chemical composition and pharmacological activities, namely, anti-inflammatory and antibacterial properties, of E. alba rhizome extract (EA). The chemical constituent was detected using the test tube method. The inflammatory model rats were obtained by inducing them with 1% carrageenan, and their palm edema volume and cytokine levels, namely, IL-6, IL-12, and TNF-α, were measured. Antibacterial activity was performed with broth microdilution. The phytochemical screening of EA was detecting alkaloids, flavonoids, tannins, steroids, and phenols. The EA has anti-inflammatory activity by reducing the palms’ edema volume and cytokine levels (IL-6, IL-12, and TNF-α), and the optimal concentration was 400 mg/kg body weight (BW). On the other hand, EA also exhibited antibacterial properties against E. coli and S. enterica. In conclusion, similar to other Etlingera plants, EA also demonstrates pharmacological activities, namely, anti-inflammatory and antibacterial properties.

Schizophrenia is a complex psychiatric disorder that exhibits an interconnection between the immune system and the brain. Experimental and clinical studies have suggested the presence of neuroinflammation in schizophrenia. In the present study, the effect of antipsychotic drugs, including clozapine, risperidone, and haloperidol (10, 20 and 20 μM, respectively), on the production of IL-1α, IL-1β, IL-2, IL-4, IL-5, IL-6, IL-10, IL-17, IL-18, INF-γ, and TNF-α was investigated in the unstimulated and polyriboinosinic-polyribocytidilic acid [poly (I:C)]-stimulated primary microglial cell cultures. In the unstimulated cultures, clozapine, risperidone, and haloperidol did not influence the cytokine levels. Nevertheless, in cell cultures under strong inflammatory activation by poly (I:C), clozapine reduced the levels of IL-1α, IL-1β, IL-2, and IL-17. Risperidone and haloperidol both reduced the levels of IL-1α, IL-1β, IL-2, and IL-17, and increased the levels of IL-6, IL-10, INF-γ, and TNF-α. Based on the results that were obtained with the antipsychotic drugs and observing that clozapine presented with a more significant anti-inflammatory effect, clozapine was selected for the subsequent experiments. We compared the profile of cytokine suppression obtained with the use of NLRP3 inflammasome inhibitor, CRID3 to that obtained with clozapine, to test our hypothesis that clozapine inhibits the NLRP3 inflammasome. Clozapine and CRID3 both reduced the IL-1α, IL-1β, IL-2, and IL-17 levels. Clozapine reduced the level of poly (I:C)-activated NLRP3 expression by 57%, which was higher than the reduction thay was seen with CRID3 treatment (45%). These results suggest that clozapine might exhibit anti-inflammatory effects by inhibiting NLRP3 inflammasome and this activity is not typical with the use of other antipsychotic drugs under the conditions of strong microglial activation.

The advantage in response of Th2 over Th1 is observed in normal pregnancy in peripheral blood. A disturbance of this balance can lead to symptoms of miscarriage and pregnancy loss. The aim of this study was to evaluate the pro- and anti-inflammatory cytokines in sera of women who were diagnosed with missed miscarriage in the first trimester and to compare this systemic immune response to the response in women with normal pregnancy. The study group consisted of 61 patients diagnosed with missed miscarriage. In total, 19 healthy women with uncomplicated first trimester created the control group. Cytokines were determined in the maternal serum by ELISA. The analysis included INF-γ, TNF-α, Il-1β, Il-4, Il-5, Il-6, Il-9, Il-10, Il-13 and TGF-β1. Th1 cytokine levels in the study group reached slightly higher values for INF-γ, Il-1β and slightly lower for IL-6 and TNF-α. In turn, Th2 cytokine levels in the study group were slightly higher (Il-9, Il-13), significantly higher (Il4, p = 0.015; Il-5, p = 0.0003) or showed no differences with the control group (Il-10). Slightly lower concentration involved only TGF-β1. Analysis of the correlation between levels of pro- and anti-inflammatory cytokines resulted in some discrepancies, without showing predominance of a specific immune response. The results did not confirm that women with missed miscarriage had an advantage in any type of immune response in comparison to women with normal pregnancy.

Inflammation is the host's protective response to any stimulus that harms the body. Excessive inflammatory process causes tissue damage. Therefore, an anti-inflammatory agent is needed. The use of natural ingredients, especially sea sponges, is an option to reduce the side effects of anti-inflammatory agents. This utilization is related to the discovery of new agents. So, we tested the effect of the ethanol extract of Petrosia sp. as an anti-inflammatory agent. Animal induced with 1% carrageenan and left for 1 hour. After that the animals were divided into 6 groups (n = 4) and given oral treatment, namely: Group I (normal group); Group II (negative group); Group III (ethanol extract of Petrosia sp. Concentration of 0.05mg/ml); Group IV (ethanol extract of Petrosia sp. Concentration 0.1mg/ml); Group V (ethanol extract of Petrosia sp. Concentration 0.2mg/ml); and Group VI (positive group, Diclofenac Sodium). After 1 hour, the animals were measured for edema volume and plasma TNF-α levels. Based on the research conducted, the ethanol extract of Petrosia sp. decreased edema volume and plasma TNF-α levels in inflammatory mice. The concentration of 0.2mg/mL had a significant effect on the negative control used (p <0.05). On the other hand, Petrosia sp. indicates the presence of alkaloids, flavonoids, and steroids. They may play an important role in the anti-inflammatory process. Thus, it can be concluded that the ethanol extract of Petrosia sp. has anti-inflammatory activity.

Inflammatory Action

Banana inflorescences are a byproduct of banana cultivation consumed in various regions of Brazil as a non-conventional food. This byproduct represents an alternative food supply that can contribute to the resolution of nutritional problems and hunger. This product is also used in Asia as a traditional remedy for the treatment of various illnesses such as bronchitis and dysentery. However, there is a lack of chemical and pharmacological data to support its consumption as a functional food. Therefore, this work aimed to study the anti-inflammatory action of Musa acuminata blossom by quantifying the cytokine levels (NOx, IL-1β, TNF-α, and IL-6) in peritoneal neutrophils, and to study its antiparasitic activities using the intracellular forms of T. cruzi, L. amazonensis, and L. infantum. This work also aimed to establish the chemical profile of the inflorescence using UPLC-ESI-MS analysis. Flowers and the crude bract extracts were partitioned in dichloromethane and n-butanol to afford four fractions (FDCM, FNBU, BDCM, and BNBU). FDCM showed moderate trypanocidal activity and promising anti-inflammatory properties by inhibiting IL-1β, TNF-α, and IL-6. BDCM significantly inhibited the secretion of TNF-α, while BNBU was active against IL-6 and NOx. LCMS data of these fractions revealed an unprecedented presence of arylpropanoid sucroses alongside flavonoids, triterpenes, benzofurans, stilbenes, and iridoids. The obtained results revealed that banana inflorescences could be used as an anti-inflammatory food ingredient to control inflammatory diseases.

Objective: To study the baseline cytokine levels and their relation with the severity of illness and mortality in critically ill children with severe sepsis. Design: Subgroup analysis of a randomized, double-blind, placebo-controlled trial. Setting: Pediatric intensive care unit of a tertiary level teaching hospital in India. Patients: Fifty children with severe sepsis aged 3 months to 12 years. Material and Methods: Blood was collected at admission for estimation of pro-inflammatory (interleukin 6 [IL-6], IL-12p70, IL-17, and tumor necrotic factor α [TNF-α]) and anti-inflammatory (IL-10 and transforming growth factor β1 [TGF-β1]) cytokines. Primary Outcome: To find out correlation between cytokine levels and severity of illness scores (Pediatric Risk of Mortality [PRISM] III score, Sequential Organ Failure Assessment [SOFA], and Vasoactive-Inotropic Score [VIS]). Secondary Outcomes: To compare cytokine levels among survivors and nonsurvivors. Results: Baseline pro-inflammatory cytokine levels (median [interquartile range]) were IL-6: 189 (35-285) pg/mL, IL-12p: 48 (28-98) pg/mL, IL-17: 240 (133-345) pg/mL, and TNF-α: 296 (198-430) pg/mL; anti-inflammatory cytokine levels were IL-10: 185 (62-395) pg/mL and TGF-β1: 204 (92-290) ng/mL. Pro-inflammatory cytokines showed positive correlation with PRISM III score: IL-6 (Spearman correlation coefficient, ρ = 0.273, P = .06), IL-12 (ρ = 0.367, P = .01), IL-17 (ρ = 0.197, P = .17), and TNF-α (ρ = 0.284, P = .05), and anti-inflammatory cytokines showed negative correlation: IL-10 (ρ = −0.257, P = .09) and TGF-β (ρ = −0.238, P = .11). Both SOFA and VIS also showed weak positive correlation with IL-12 (ρ = 0.32, P = .03 and ρ = 0.31, P = .03, respectively). Among nonsurvivors (n = 5), the levels of all the measured pro-inflammatory cytokines were significantly higher as compared to survivors, IL-6: 359 (251-499) pg/mL versus 157 (97-223) pg/mL, P < .0001, IL-12p70: 167 (133-196) pg/mL versus 66 (30-100) pg/mL, P < .0001, IL-17: 400 (333-563) pg/mL versus 237 (122-318) pg/mL, P = .009, and TNF-α: 409 (355-503) pg/mL versus 330 (198-415) pg/mL, P = .002, respectively. Conclusion: In critically ill children with severe sepsis, pro-inflammatory cytokines (especially IL-12p70) showed a weak positive correlation with severity of illness and were significantly higher among nonsurvivors.

A series of 3-[2-chloroquinolin-3-yl)methylene]-5-aryl-furan-2(3H)-ones {3(a-p)} were synthesized. The required 3-(substitutedbenzoyl) propionic acids {2(a-d)} were prepared under Friedal Craft acylation reaction conditions. The substituted 2-chloroquinoline-3-carbaldehydes {1(a-d)} were synthesized by reaction of substitutedphenylethanone-oxime with phosphorus oxychloride in presence of dimethyl formamide using the Vilsmeir Haack reaction method. These compounds were screened for their anti-inflammatory and antibacterial activities along with their ulcerogenic and lipid peroxidation potentials. The compounds that showed significant anti-inflammatory activity were further screened for their analgesic activity. The compounds were less toxic in terms of ulcerogenicity as compared to a standard, which was also supported by lipid peroxidation studies. The antibacterial activities were performed against Staphylococcus aureus and Escherichia coli. Compounds 3f, 3n and 3o showed significant activity against both S. aureus and E. coli having an MIC value of 6.25?g mL-1.

Background: Bacteria playing a role in periodontitis are Gram-negative anaerobic bacteria that can release endotoxin or lipopolysaccharide (LPS). LPS acts as a stimulus to a variety of host cells that can stimulate expression of pro-inflammatory cytokines in periodontal disease, such as IL-1α, IL-1β, and TNF-α. Increased TNF-α then can lead to periodontal tissue destruction. Furthermore, cassava leaves have many health benefits due to flavonoid organic compound contained, known to possess anti-inflammatory activity are used as a medicine. Purpose: This study aimed to determine the effect of cassava leaf flavonoid extract as a basic ingredient of anti-inflammatory gel on TNF-α expression in Wistar rats suffering from periodontitis induced with Escherichia coli (E. coli) LPS. Method: This study used 24 male Wistar rats. Those rats were divided into six groups. Group 1 consisted of four rats induced with E. coli LPS for 2 weeks, and then decapitation was performed on day 3. Group 2 consisted of four rats induced with E. coli LPS for 2 weeks, and then decapitation was conducted on day 7. Group 3 consisted of four rats induced with E. coli LPS for 2 weeks, treated with the topical cassava leaf flavonoid extract gel (Manihot esculenta) at a concentration of 25%, and then decapitation was performed on day 3. Group 4 consisted of four rats induced with E. coli LPS for 2 weeks, treated with the topical cassava leaf flavonoid extract gel (Manihot esculenta) at a concentration of 25%, and then decapitation was conducted on day 7. Group 5 consisted of four rats induced with E. coli LPS for 2 weeks, treated with the topical cassava leaf flavonoid extract gel (Manihot esculenta) at a concentration of 50%, and then decapitation was performed on day 3. And, group 6 consisted of four rats induced with E. coli LPS for 2 weeks, treated with the topical Cassava leaf flavonoid extract gel (Manihot esculenta) at a concentration of 50%, and then decapitation was conducted on day 7. The topical Cassava leaf flavonoid extract gel was inserted into gingival sulcus on the first right molar of their lower jaw by using a blunted syringe needle. The gel was given two times a day for 7 days. Result: The expression of TNF-α in the control group was more than that in the treatment groups given the Cassava leaf flavonoid extract gel at the concentrations of 25% and 50%. The expression of TNF-α in the treatment groups given the cassava leaf flavonoid extract gel at the concentration of 50% was lower than that in the treatment groups given the cassava leaf flavonoid extract gel at the concentration of 25%. Conclusion: Cassava leaf flavonoid extract gel could be used as an anti-inflammatory gel characterized by a decrease in TNF-α expression in rat models suffering from periodontitis.

We investigated whether LPS-induced hypothermia develops in a serotype-specific manner in biotelemetered conscious rats. Two different Escherichia coli serotypes of LPSs were injected at a dose of 250 μg/kg ip. E. coli O55:B5 LPS elicited an initial hypothermia and subsequent fever, but E. coli O111:B4 LPS caused more potent monophasic hypothermia. Serum tumor necrosis factor (TNF)-α levels were dramatically elevated at the initial phase of the hypothermia induced by both LPSs. This elevation tended to subside at the nadir of E. coli O55:B5 LPS-induced response but progressively increased at the nadir of E. coli O111:B4 LPS hypothermia. Serum IL-10 levels were moderately elevated at the initial phase of the hypothermia and persisted at the same level at the nadir of each LPS-induced response. No change was observed at the serum IL-18 levels. A selective cyclooxygenase (COX)-1 enzyme inhibitor, valeryl salicylate (20 mg/kg sc), abolished the hypothermia without any effect on the elevated cytokine levels. Another COX-1-selective inhibitor, 5-(4-chlorophenyl)-1-(4-methoxyphenyl)-3-(trifluoromethyl)-1H-pyrazole (SC-560; 1 mg/kg sc) inhibited hypothermic responses as well. Meanwhile, cytokine levels were also reduced by SC-560 treatment. These findings suggest that LPS-induced hypothermia may have serotype-specific characteristics in rats. E. coli O111:B4 LPS has more potent hypothermic activity than E. coli O55:B5 LPS; that may presumably be related to its higher or sustained capability to release antipyretic cytokines, such as TNF-α. COX-1 enzyme may be involved in the generation of the hypothermia, regardless of the type of LPS administered.

Background: Cytokines play an important role in signaling the immune system to build an adequate immune responseagainst HIV. HIV distorts the balance between pro and anti-inflammatory cytokines causing viral replication. Highly active antiretroviral treatment (HAART) acts by trying to restore pro and anti-inflammatory cytokine balance. It is not clear how HAART non-adherence influences circulating cytokine levels. This study therefore determined cytokine levels in HAART non-adherent individuals. Methods: This cross-sectional study recruited 163 participants (51 controls, 23 HIV-1+ HAART naive, 28 HAART-adherent6 months, 19 HAART-adherent 12 months and 42 HAART non-adherent). Cytokines were analyzed by ELISA while CD4 T cells determined in 3.0 μl of whole blood using BD FACSCaliburTM and viral load in 0.2ml plasma sample using Abbott Molecular m2000sp sample preparation and m2000rt real-time amplification and detection systems (Abbott MolecularInc., Illinois, USA) according to the manufacturer’s methods. Results: IL-4, IL-6, IL-10, TNF-α and TGF-β were significantly elevated in HIV-1 HAART non-adherent compared withHIV-1 HAART adherent and healthy controls P<0.01. IFN- γ was significantly decreased in HIV-1 HAART non-adherentcompared with HIV-1 HAART adherent and healthy controls P<0.01. TNF-α and TGF-β were significantly reduced in HIV-1 HAART adherent patients at 12 months compared to those at 6 months P<0.01. IL-4 and IL-10 correlated positively withviral load. IL-4, IL-6, IL-10, TNF-α and TGF- β associated inversely with CD4 T cell counts and body mass index (BMI). Conclusion: This study established that HAART adherence is immunologically beneficial to the pro and anti-inflammatory cytokine balance milieu while non-adherence appears to cause alterations in pro and anti-inflammatory cytokines warping the balance in this dichotomy. Keywords: Cytokines; non-adherence; HAART.
