BACKGROUND: Fertility is affected by both the reproductive organs and external factors (genetics, hormones, radiation exposure, use of insecticides, and nutrition). The histological structure of the ovaries is an indicator of reproductive function. Insect repellent use with pyrethroid active ingredients and its impact on health has become a discussion in the medical sector for years. Disruption of the reproductive system homeostasis may cause several issues, from disruption of ovarian function to infertility. γ-Oryzanol has higher antioxidants than vitamin E. It is found mostly in rice bran oil (RBO). Researchers have investigated the effectiveness of RBO and γ-Oryzanol, but the number of studies focusing on the reproductive system is very limited. Results of in silico showed anti-inflammatory potential, and nitric oxide γ-Oryzanol is stronger than the antioxidant activity. It also showed γ-Oryzanol bond with Foxo3a and Growth Differentiating Factor 9 (GDF9), indicating the γ-Oryzanol potential for reproductive health (women). Studies also reported that γ-Oryzanol administration caused anti-inflammatory and antioxidant activity compared to RBO in improving ovarian physiological function using tumor necrosis factor α (TNF-α) levels, Foxo3a expression, and GDF9 expression exposed to one push transfluthrin as the parameter. AIM: We aimed to investigate antioxidant and anti-inflammatory activity of γ-Oryzanol compared to rice bran oil to repair ovarian histological structure from one push transfluthrin exposure effect. METHODS: Experimental research, post-test only control group design approach, with a completely randomized design, consisted of 6 (six) groups of Wistar strain female rats. They were exposed to one push with the active ingredient of transfluthrin 21.3%, by inhalation for 6 hours, RBO 0.3 mg/g/ body weight (BW)/day, γ-Oryzanol 3.75 ml/g/BW/day. Statistical analysis was done with the Mann Whitney’s posthoc Kruskal Wallis test with IBM SPSS version 25 software. RESULTS: γ-Oryzanol had more potent anti-inflammatory and antioxidant activity than RBO in improving the ovarian histology structure (including maintaining ovarian weight, increasing follicular growth, and suppressing follicular abnormalities) through decreased TNF-α levels and decreased Foxo3a expression, and increased GDF9 expression. CONCLUSION: The administration of γ-Oryzanol improves the ovarian histological structure from free radicals effects, namely exposure to one push of transfluthrin.

Abstract Background Inflammation is a symptom associated with many diseases. This symptom is treated with steroidal and non-steroidal anti-inflammatory drugs, which can cause severe side effects when used as long-term treatments. Natural products are an alternative source of new compounds with anti-inflammatory activity. Jefea gnaphalioides (Astereaceae) (A. Gray) is a plant species used to treat inflammatory problems, in Mexico. This study determined the anti-inflammatory activity and the composition of the methanol extract of Jefea gnaphalioides (MEJG). Methods The extract was obtained by heating the plant in methanol at boiling point for 4 h, and then the solvent was evaporated under vacuum (MEJG). The derivatization of the extract was performed using Bis-(trimethylsilyl) trifluoroacetamide, and the composition was determined by GC-MS. Total Phenols and flavonoids were determined by Folin-Ciocalteu AlCl3 reaction respectively. The antioxidant activity of MEJG was determined by DPPH method. The acute and chronic anti-inflammatory effects were evaluated on a mouse ear edema induced with 12-O-Tetradecanoylphorbol-13-acetate (TPA). Acute oral toxicity was tested in mice at doses of MEJG of 5000, 2500 and 1250 mg/kg. The levels of NO, TNF-α, IL-1β and IL-6 were determinate in J774A.1 macrophages stimulated by Lipopolysaccharide. The production of inflammatory interleukins was measured using commercial kits, and nitric oxide was measured by the Griess reaction. Results The anti-inflammatory activity of MEJG in acute TPA-induced ear edema was 80.7 ± 2.8%. This result was similar to the value obtained with indomethacin (IND) at the same dose (74.3 ± 2.8%). In chronic TPA-induced edema at doses of 200 mg/kg, the inhibition was 45.7%, which was similar to that obtained with IND (47.4%). MEJG have not toxic effects even at a dose of 5000 mg/kg. MEJG at 25, 50, 100 and 200 μg/mL decreased NO, TNF-α, IL-1β and IL-6 production in macrophages stimulated with LPS. The major compounds in MEJG were α-D-Glucopyranose (6.71%), Palmitic acid (5.59%), D-(+)-Trehalose (11.91%), Quininic acid (4.29%) and Aucubin (1.17%). Total phenolic content was 57.01 mg GAE/g and total flavonoid content was 35.26 mg QE/g MEJG had antioxidant activity. Conclusions MEJG has anti-inflammatory activity.

Abstract Background This study evaluated the in vitro antioxidant activity and comparison of anti-inflammatory and cytotoxic activity of Harpagopytum zeyheri with diclofenac. Methods In vitro assays were conducted using water, ethanol and ethyl acetate extracts of H.zeyheri. The antioxidant activity was evaluated using the 2,2'-diphenyl-1-picrylhydrazy (DPPH) and 2,2'- azino-bis (3-ethylbenzothiazoline-6-sulphonic acid) (ABTS)assays. The anti-inflammatory activity was determined by measuring the inhibition of nitric oxide (NO) on lipopolysaccharide (LPS)-induced RAW 264.7 mouse macrophages as well as cytokine (TNF-α and IL-10) expression on LPS-induced U937 human macrophages. For cytotoxicity, cell viability was determined using the 3-(4, 5-dimethylthiazol- 2-yl)-2,5-diphenyl tetrazolium bromide (MTT) assay. Results The ethyl acetate extract had the lowest IC50 values in the DPPH (5.91µg/ml) and ABTS (20.5µg/ml) assay compared to other extracts. Furthermore, the ethyl acetate extracts effectively inhibited NO and TNF-α and proved to be comparable to diclofenac at some concentrations. All extracts of H. zeyheri displayed dose dependent activity and were associated with low levels of human-IL-10 expression compared to quercetin. Furthermore, all extracts displayed low toxicity relative to diclofenac. Conclusions These findings show that H. zeyheri has significant antioxidant activity. Additionally, similarities exist in inflammatory activity of H. zeyheri to diclofenac at some concentrations as well as low toxicity in comparison to diclofenac.

This trial was performed to determine the effect of rice bran oil (RBO) inclusion in diets of broiler chickens on performance, carcass characteristics, blood parameters, meat quality, antioxidant activity, liver lipid content, and liver histological structure. The 35-day feeding trial was conducted on 240 one-day-old Ross 308 broiler chickens, allocated to four treatment groups with six replicates each. RBO was examined at different inclusion levels, 0% (control), 1% (RBO1%), 1.5% (RBO1.5%), and 2% (RBO2%) in a completely randomized design. The results showed that at the end of the trial (35 days) the RBO supplementation had positive effects (p < 0.001) on the productivity parameters, but the feed intake was linearly decreased due to RBO inclusion. In addition, RBO supplementation linearly improved (p < 0.05) the dressing percentage, breast yield, immune organs relative weights, and meat glutathione concentration, while it decreased (p < 0.01) the abdominal fat yield and meat crude fat, triglycerides, cholesterol, and Malondialdehyde (MDA) contents in broiler’s meat. Moreover, serum total protein, globulin, and high-density lipoprotein contents improved noticeably (p < 0.01) due to offering an RBO-supplemented diet, but serum total lipids, total cholesterol, triglyceride, low-density lipoprotein, and aspartate aminotransferase concentrations linearly reduced (p < 0.01). The RBO supplementation augmented (p < 0.05) the phagocytic index, phagocytic activity, and antibody titer compared to control. On the other hand, RBO inclusion had no effect on the breast, thigh, or abdominal fat color parameters. Moreover, RBO supplementation reduced (p < 0.01) the content of total saturated FA (SFA), but increased (p < 0.01) the content of total monounsaturated FA (MUFA), and polyunsaturated FA in both breast and thigh meat. Chemical analysis of the liver tissue samples revealed that the inclusion of RBO linearly reduced (p < 0.05) hepatic cholesterol, triglyceride, and MDA contents. Histologically, the lipid percentage and number of lipid droplets (p < 0.01) were markedly lessened in the RBO-supplemented groups. The histological structure of the liver asses by light and electron microscope were normal in all groups without any pathological lesions. It is concluded that RBO could be used as a valuable ingredient in broiler chickens’ diets to stimulate the growing performance and immune status, enhance the antioxidant activity and blood lipid profile, augment liver function, and improve the nutritive value of the meat.

Background: NSAIDs are the most widely prescribed medications worldwide for their anti-inflammatory, antipyretic, and analgesic effects However, their chronic use can lead to several adverse drug events including GI toxicity. The selective COX-2 inhibitors developed as gastro-sparing NSAIDs also suffer from serious adverse effects which limit their efficacy. Objective: Local generation of reactive oxygen species is implicated in NSAID-mediated gastric ulceration and their combination with H2 antagonists like famotidine reduces the risk of ulcers. The objective of this work was to design and synthesize novel methanesulphonamido isoxazole derivatives by hybridizing the structural features of NSAIDs with those of antiulcer drugs (ranitidine, famotidine, etc.) to utilize a dual combination of anti-inflammatory activity and reducing (antioxidant) potential. Method: The designing process utilized three dimensional similarity studies and utilized an isoxazole core having a potential for anti-inflammatory as well as radical scavenging antioxidant activity. The compounds were assayed for their antiinflammatory activity in established in vivo models. The in vitro antioxidant activity was assessed in potassium ferricyanide reducing power (PFRAP) assay employing ascorbic acid as the standard drug. Results: Compounds (5, 6, 9 and 10) showed anti-inflammatory activity comparable to the standard drugs and were also found to be non-ulcerogenic at the test doses. Compounds 6-10 exhibited good antioxidant effect in the concentration range of 1.0-50.0 µmol/ml. The test compounds were also found to comply with the Lipinski rule suggesting good oral absorption. Conclusion: A new series of isoxazole based compounds is being reported with good anti-inflammatory activity coupled with antioxidant potential as gastro-sparing anti-inflammatory agents.

AbstractFisetin is a naturally occurring flavonoid that possesses several pharmacological benefits including anti-inflammatory activity. However, its precise anti-inflammatory mechanism is not clear. In the present study, we found that fisetin significantly inhibited the expression of proinflammatory mediators, such as nitric oxide (NO) and prostaglandin E2 (PGE2), and cytokines, such as interleukin-6 (IL-6) and tumor necrosis factor-alpha (TNF-α), in lipopolysaccharide (LPS)-stimulated RAW 264.7 macrophages. Additionally, fisetin attenuated LPS-induced mortality and abnormalities in zebrafish larvae and normalized the heart rate. Fisetin decreased the recruitment of macrophages and neutrophils to the LPS-microinjected inflammatory site in zebrafish larvae, concomitant with a significant downregulation of proinflammatory genes, such as inducible NO synthase (iNOS), cyclooxygenase-2a (COX-2a), IL-6, and TNF-α. Fisetin inhibited the nuclear localization of nuclear factor-kappa B (NF-κB), which reduced the expression of pro-inflammatory genes. Further, fisetin inactivated glycogen synthase kinase 3β (GSK-3β) via phosphorylation at Ser9, and inhibited the degradation of β-catenin, which consequently promoted the localization of β-catenin into the nucleus. The pharmacological inhibition of β-catenin with FH535 reversed the fisetin-induced anti-inflammatory activity and restored NF-κB activity, which indicated that fisetin-mediated activation of β-catenin results in the inhibition of LPS-induced NF-κB activity. In LPS-microinjected zebrafish larvae, FH535 promoted the migration of macrophages to the yolk sac and decreased resident neutrophil counts in the posterior blood island and induced high expression of iNOS and COX-2a, which was accompanied by the inhibition of fisetin-induced anti-inflammatory activity. Altogether, the current study confirmed that the dietary flavonoid, fisetin, inhibited LPS-induced inflammation and endotoxic shock through crosstalk between GSK-3β/β-catenin and the NF-κB signaling pathways.

Aims: The present investigation was aimed at exploring the phytoconstituents using Gas Chromatography Mass Spectroscopy and to evaluate antioxidant and anti-inflammatory properties of the leaf extracts. Materials and Methods: The extracts were obtained sequentially with petroleum ether, ethyl acetate and water using soxhlet apparatus. The anti-inflammatory property of the identified compounds using GC- MS spectroscopy was evaluated in silico. The antioxidant activity was performed by DPPH and H2O2 method whereas anti-inflammatory study was carried out by HRBC membrane stabilization method. Terpenoids were found to be major constituents in petroleum ether extract while, phenols and flavonoids were predominantly found in ethyl acetate extract. Results and Discussion: The GC-MS analysis of the extract revealed six major molecules including Squalene, 19β, 28- epoxyleanan-3-ol and 2-tu-Butyl-5-chloromethyl-3-methyl-4-oxoimidazolidine-1-carboxylic acid. The ethyl acetate extract showed a significant antioxidant activity (P<0.01) in both DPPH method (70.87 %) and H2O2 method (73.58%) at 200 µg mL-1 . Increased membrane stabilization of petroleum ether extract was observed in the in vitro anti-inflammatory activity study. A strong relationship between the terpenoid content and anti-inflammatory activity was obtained from the correlation (0.971) and docking study. Conclusion: These results justify T. involucrata to be a rich source of terpenoids with potent antiinflammatory property.
