Obesity is associated with several co-morbidities including chronic pain. Systemic low-grade chronic inflammation and dysregulation of pro-inflammatory cytokines have been proposed to underlie these phenomena. This study characterized pain and inflammation, and levels of the pro-inflammatory cytokine visfatin, in a rodent model of obesity, and investigated whether treatment with the visfatin inhibitor, FK866, has anti-inflammatory and/or analgesic effects in normal and obese rats. The effects of pre-administration of FK866 (3, 10 mg/kg; i.p.) on carrageenan (3%; i.d. into the left paw)-induced thermal and mechanical hypersensitivity and paw oedema was measured in adult male Wistar rats fed a normal diet (ND) or high fat diet (HFD) for 12 weeks. HFD-fed rats displayed an increased sensitivity to acute mechanical nociceptive stimulation, and potentiated mechanical hyperalgesia and peripheral inflammation to carrageenan. Levels of circulating visfatin were increased in HFD-fed rats. Treatment with FK866, a visfatin inhibitor, was effective in reducing carrageenan-induced hyperalgesia and paw oedema in both ND-fed and HFD-fed rats. These data show that FK866 has anti-inflammatory and analgesic properties. The potentiated response to pain and inflammation, and elevated visfatin levels in HFD-fed rats supports the hypothesis that obesity is a chronic low-grade inflammatory disorder. Reversal of this co-morbidity by blocking visfatin may be a novel therapeutic strategy for managing pain with obesity.

Summary Introduction: Potato (Solanum tuberosum L.) is an important vegetable crop in Syria. Potato tuber moth Cussonia barteri is a small tree that grows in the sub-Saharan part of Africa. Various parts of the plant are used for the treatment of a variety of ailments in ethno-medicine. Objective: To evaluate the anti-inflammatory and analgesic effect of the methanol leaf extract of Cussonia barteri. Material and methods: The leaves were air-dried, powdered and repeatedly extracted with methanol using a Soxhlet apparatus. The resulting methanol extract (100, 200 and 400 mg/kg) was evaluated for anti-inflammatory activity using carrageenan-induced paw oedema, xylene-induced ear oedema and formalin-induced arthritis tests. Analgesic effect was evaluated using acetic acid-induced mouse writhing, hot plate and tail flick tests. Results: All doses of the extract significantly (p<0.05) reduced carrageenan-induced paw oedema, however the 400 mg/kg dose gave a sustained effect. The extract significantly inhibited xylene induced ear oedema at all doses. There were no significant (p>0.05) reductions in paw swellings due to formalin. In the acetic acid induced writhing test, the extract significantly (p<0.05) decreased writhing at 400 mg/kg only. Reaction times were not significantly different from the control in the hot plate and tail flick tests. Conclusion: This study has shown that the methanol extract possesses acute anti-inflammatory and peripherally mediated analgesic effects.

Abstract Objectives Obesity-induced, chronic, low-grade inflammation is involved in the pathogenesis of cardiovascular disease (CVD). Numerous spices have anti-inflammatory properties in animal models and humans. However, few studies have examined the anti-inflammatory effect of spices in the context of daily meal consumption, which is typically how spices are consumed. The objective of this study was to investigate the anti-inflammatory effect of chronic spice consumption in adults with overweight/obesity at risk for CVD. Methods Nonsmoking adults (30–75 years old) with overweight/obesity (BMI ≥ 25 and ≤ 35 kg/m2), elevated waist circumference (≥94 cm for men and ≥ 80 cm for women) and at least one other risk factor for CVD were recruited for a 3-period, crossover, randomized controlled-feeding study (n = 63). In random order, participants consumed an Average American Diet (AAD) for 4 weeks containing: 1) 0.6 g of spice blend per 2100 kcal, 2) 3.2 g of spice blend per 2100 kcal, or 3) 6.4 g of spice blend per 2100 kcal with a≥2-week washout period between each test period. The spice blend was comprised of 24 popular spices. Blood was collected at baseline and after each test period. Peripheral blood mononuclear cells were isolated, and the % of monocyte subsets (classical; CD14++CD16−, intermediate; CD14++CD16+, non-classical; CD14+CD16++) were quantified using flow cytometry. Plasma pro-inflammatory cytokine levels (TNF-α, IL-1β, IL-6, IL-8, MCP-1) were measured using ELISA. In a subset of participants (n = 6), transendothelial migratory function of each monocyte subset through MCP-1 stimulated human umbilical vein endothelial cells was evaluated. Results Plasma IL-6 was significantly reduced after consuming the AAD containing 3.2 g compared to 0.6 g of spice blend in men and postmenopausal women (P = 0.031). Transendothelial migration of classical monocytes was significantly reduced following consumption of the AAD containing 3.2 g and 6.4 g of the spice blend compared to 0.6 g of spice blend (P = 0.011). Conclusions Consumption of an AAD with spices for 4 weeks attenuated inflammatory outcomes including plasma IL-6 and transendothelial migration of classical monocytes in adults with overweight/obesity.

Heliotropium indicum is a plant of the Boraginaceae family reported to have multiple beneficial health effects, including analgesic, anti-malaria, anti-microbial, anti-tumor, anti-inflammatory, amongst others. 42 Male Wistar rats were used for this study. Group A served as control and received distilled water only. Groups B, C, D, E, and F were fed with the extract of Heliotropium Indicum in different concentrations. (500 mg/kg, 1000 mg/kg, 1500 mg/kg 2000 mg/kg and 3000 mg/kg) respectively. This study showed that Heliotropium indicum contains phytochemicals such as saponins tannins, cardiac glycosides, and terpenoids. Our results revealed that Heliotropium indicum decreased the ALT, AST, ALP, and bilirubin levels, especially at doses from 1500 mg/kg B.W. Also, inflammatory cytokine expressions were significantly reduced at similar doses. However, the level of antioxidants (GSH, CAT, GST, SOD, GPx) were significantly increased by Heliotropium indicum administration at doses ranging from 1500 mg/kg to 3000 mg/kg. The antioxidative potentials of Heliotropium indicum are further complemented by its ability to reduce inflammatory cytokine expression, including TNF-α, IL-1β, IL-6, COX-2 as well as NO and LPO. Ethanol extract of Heliotropium indicum at doses between 1500 mg/kg and 3000 mg/kg has antioxidative, anti-inflammatory effects and can counteract lipid peroxidation.

Background: Inflammation is a complex process mainly comprises of three phases namely acute, sub-acute and chronic. In acute inflammatory conditions fluid and granulocytic cells accumulate at the site of injury because of the changes in small blood vessels. This response often activates systemic response such as leucocytosis, protein catabolism, fever and synthesis of C-reactive protein, an acute-phase protein In Ayurvedic texts, several herbo-mineral preparations to fight against inflammation have been found; among them, Vatavidhvamsana Rasa (VVR) is one, which is said to be remarkable in inflammation condition. Aim and Objectives: To assess the anti-inflammatory and analgesic effects of VVR in pharmacologically validated models. Materials and methods: Wistar strain albino rats weighing 200 ± 20 of either sex were used in the study. VVR was administered at a dose of 22.5 mg/kg for the rat. Results: Vatavidhvamsana Rasa (VVR) showed a significant decrease in the carrageenan-induced paw oedema after 1-hour interval in comparison to the control group (P<0.05) and at 3 hours and 5 hours intervals it showed a non-significant decrease in carrageenan-induced paw oedema in albino rats.  In the analgesic activity, VVR treated group showed a significant increase in radiant heat response at 30 min. interval (P<0.05) and non-significant increase at 60 mins in comparison to initial and control group. Conclusion: The results concluded that Vatavidhvamsana Rasa has anti-inflammatory and analgesic activity. Accordingly, it can be used in the management of pain and inflammatory conditions.

AbstractIntroductionCoronary artery disease (CAD) is one of the major causes of death worldwide. Despite extensive treatments, many patients still exhibit low-grade systemic inflammation which increases risk of new cardiovascular events. Currently, there is no standard anti-inflammatory strategy to treat CAD.Lutein is an antioxidant abundant in the Mediterranean diet which is known to be cardioprotective. We have previously shown that plasma lutein is inversely correlated to inflammation levels in CAD patients and that it exerts direct anti-inflammatory effects on patients’ immune cells ex vivo. We have also demonstrated that consuming spinach in the form of smoothie can maximize lutein liberation in vitro. The present study is a feasibility study in preparation for a cross-over intervention study in CAD patients. It aimed to compare the efficacy and practicality of raising plasma lutein using lutein-rich smoothies or lutein supplements.Materials and methods7 healthy participants were advised to consume 1) 85 g spinach in smoothies ≥ 5 days/week or 2) 10 mg lutein supplements daily in a cross-over design in two separate 8-week interventions while keeping their usual diets. A 6-week washout period during which their normal diet was maintained separates the two intervention periods. Training on smoothie making was provided. Adherence was recorded daily, and the practicality was ranked in surveys fortnightly. Plasma was collected on 11 occasions. Plasma carotenoids (lutein, β-cryptoxanthin, lycopene, α-carotene and β-carotene) were quantified by HPLC.ResultsBoth interventions received the two highest scores in terms of taste, ease of use and time consumption. Plasma lutein was increased by both interventions while no change was found in other plasma carotenoids. The lutein-raising effect was higher in supplements compared to smoothies. The smoothies raised plasma lutein levels on an average of 117 %, 143 %, 167 % and 142% from baseline after 2, 4, 6 and 8 weeks of consumption respectively (Pfor trend = 0.003). The lutein supplements increased plasma lutein on an average of 519 %, 637 %, 672 % and 715 % from baseline after 2, 4, 6 and 8 weeks respectively (Pfor trend = 0.002). Lutein returned to baseline levels for all participants 4 and 6 weeks after the smoothies and 8 and 10 weeks after the supplements.DiscussionBoth methods are effective in increasing plasma lutein in healthy humans. Although the supplements exert higher lutein-raising effects compared to the smoothies, further testing on subjects with CAD is required to determine if the observed effects lead to inflammation reduction with clinical significance.

Abstract Trees and shrubs of the genus Cordia are widely distributed in the warmer regions, including Indonesia. The aim of this study was to evaluate the analgesic and anti-inflammatory properties of the ethanolic extract of plant leaves in Wistar albino rats. The analgesic activity was evaluated using the hot plate method and acetic acid-induced writhing, and the anti-inflammatory activity was determined using carrageenan-induced paw oedema. The results showed that the Cordia sebestena ethanol extract (100, 200 and 400 mg/kg) exhibited significant analgesic effects in a dose-dependent manner in the two pain models tested. The extract also exhibited significant anti-inflammatory effects in the carrageenan-induced inflammation test. The data obtained support the traditional folklore therapeutic claim about its analgesic and anti-inflammatory properties. Nonetheless, further scientific investigation is required to establish its analgesic and anti-inflammatory properties in other experimental models and clinical settings.

The anti-inflammatory and analgesic effects of the ethanolic extract (SLEE) and fruticulin A from the leaves ofSalvia lachnostachyswere evaluated in mice, using experimental models of inflammation (paw oedema and pleurisy induced by carrageenan injection) and hyperalgesia (electronic Von Frey). Oral administration of SLEE (30, 100, and 300 mg/kg) and fruticulin A (0.3 and 3.0 mg/kg) decreased the total leucocytes number in pleural lavage, protein extravasation, and paw oedema. SLEE (100 mg/kg) and fruticulin A (3 mg/kg) also exhibited antihyperalgesic activity in carrageenan induced mechanical hyperalgesia. In addition, fruticulin A (3 mg/kg) prevented mechanical hyperalgesia, inhibiting TNF but not L-DOPA-induced mechanical hyperalgesia. In conclusion, SLEE and fruticulin A display anti-inflammatory and analgesic properties. Therefore, fruticulin A is at least partially responsible for the activity observed in the ethanolic extract ofSalvia lachnostachys.

Background: The objective of the study was to investigate the effect of fenofibrate on acute and subacute models of inflammation in adult male Wistar rats.Methods: After obtaining clearance from Institutional Animal Ethics Committee, six adult male Wistar rats were allocated to each of the three groups i.e. control, aspirin and fenofibrate. Acute inflammation was studied using carrageenan induced rat paw oedema and the volume displacement due to paw oedema was measured using the plethysmograph. Subacute inflammation was studied using foreign body insertion (cotton pellet and grass pith) models. Dry granuloma weight and histopathological examination of the granuloma were the outcome measures for measuring subacute inflammation. The percentage inhibition of inflammation with aspirin and fenofibrate was calculated in both acute and subacute models. The experiments were conducted according to the guidelines of the Committee for the Purpose of Control and Supervision on Experiments on Animals (CPCSEA). The mean volume displacement obtained with a plethysmograph, the mean dry weight of granuloma and the percentage inhibition with aspirin and fenofibrate were analyzed by one way analysis of variance (ANOVA) using Graph pad prism software.Results: Aspirin and fenofibrate significantly reduced both acute and subacute inflammation (p<0.001). Dunnet’s test showed a significant difference in the study groups when compared to the control. The reduction of inflammation with fenofibrate was comparable to aspirin.Conclusions: Oral fenofibrate showed significant anti-inflammatory activity, which was comparable to aspirin, in both acute as well as sub-acute models of inflammation. This anti-inflammatory effect may benefit atherosclerosis in patients receiving fenofibrate for hyperlipidemia.
