BACKGROUND:In this clinical trial we compared the effects of broccoli sprouts powder, as an alternative and complementary treatment, to those of standard triple therapy, as a common medical treatment, on cardiovascular risk factors following the H.pylori eradication in patients with type 2 diabetes.

METHODS:Eighty-six type 2 diabetic patients with positive H.pylori stool antigen test (HpSAg) were randomized to receive one of the three following regimens: STT) Standard triple therapy (omeprazole 20 mg, clarithromycin 500 mg, amoxicillin 1000 mg, twice a day for 14 days), BSP) 6 g/d broccoli sprouts powder for 28 days, and combination of these as STT + BSP. After 4 weeks of treatment, H.pylori eradication rates were assessed by HpSAg. Anthropometric measures, blood pressure, serum lipids and lipoproteins as well as serum high sensitive- C reactive protein were also assessed at baseline and at the second examination.

RESULTS:Seventy-seven participants completed the study [STT (n = 28), BSP (n = 25), STT + BSP (n = 24)]. The H.pylori eradication rates were 89.3%, 56.0% and 91.7% in STT, BSP and STT + BSP groups, respectively. After the treatment, both systolic and diastolic blood pressure significantly decreased in STT + BSP group (P < 0.05). Serum triglycerides and TG/HDL-C ratio increased in STT patients group (<0.05). Serum hs-CRP levels significantly decreased in the patients who were treated with BSP per se (3.0 ± 2.5 at baseline vs. 2.3 ± 2.1 after the treatment, P < 0.05).

CONCLUSION:Compared to standard triple therapy, BSP regimen in addition to considerable effects on H.pylori eradication had also favorable properties on cardiovascular risk factors following the H.pylori eradication.

Novel coronaviruses (CoV) have emerged periodically around the world in recent years. The recurrent spreading of CoVs imposes an ongoing threat to global health and the economy. Since no specific therapy for these CoVs is available, any beneficial approach (including nutritional and dietary approach) is worth investigation. Based on recent advances in nutrients and phytonutrients research, a novel combination of vitamin C, curcumin and glycyrrhizic acid (VCG Plus) was developed that has potential against CoV infection. System biology tools were applied to explore the potential of VCG Plus in modulating targets and pathways relevant to immune and inflammation responses. Gene target acquisition, gene ontology and Kyoto encyclopedia of genes and genomes (KEGG) pathway enrichment were conducted consecutively along with network analysis. The results show that VCG Plus can act on 88 hub targets which are closely connected and associated with immune and inflammatory responses. Specifically, VCG Plus has the potential to regulate innate immune response by acting on NOD-like and Toll-like signaling pathways to promote interferons production, activate and balance T-cells, and regulate the inflammatory response by inhibiting PI3K/AKT, NF-κB and MAPK signaling pathways. All these biological processes and pathways have been well documented in CoV infections studies. Therefore, our findings suggest that VCG Plus may be helpful in regulating immune response to combat CoV infections and inhibit excessive inflammatory responses to prevent the onset of cytokine storm. However, further in vitro and in vivo experiments are warranted to validate the current findings with system biology tools. Our current approach provides a new strategy in predicting formulation rationale when developing new dietary supplements.

BACKGROUND: Elemental diet is considered an effective primary treatment for active Crohn's disease, but it is usually given by a feeding tube.

METHODS: Twenty-two patients (12 males, median age 30 years, range 18-60) with moderately active Crohn's disease were enrolled in a randomized study in which the efficacy of an elemental diet administered orally was compared to high-dose corticosteroids in achieving clinical and laboratory remission. Ten patients were treated by oral elemental diet (Peptamen, Clintec, USA) and 10 received corticosteroids. Both treatment regimens lasted 2 weeks. The two groups did not differ with respect to age, sex, body weight, location of disease, treatment or disease activity prior to the study. In all patients studied, simple Crohn's disease activity index, nutritional status (expressed as body mass index), percentage of ideal body weight, fat mass, fat free mass, erythrocyte sedimentation rate, interleukin-6, intestinal permeability (expressed as permeability index), prealbumin, retinol binding protein and multiskin test were evaluated before and after treatment.

RESULTS: After 2 weeks of treatment, there were significant improvements in simple Crohn's disease activity index, erythrocyte sedimentation rate, permeability index, body mass index, prealbumin, retinol binding protein and multiskin test in the elemental diet group. There were significant improvements in simple Crohn's disease activity index and fat free mass in the corticosteroid group.

CONCLUSIONS: These data suggest that, in the short term, an oral elemental diet is at least as effective as steroids in inducing remission of mild-moderately active Crohn's disease, but it may be more effective in improving the nutritional status of these patients, probably through a more rapid restoration of normal intestinal permeability.

The treatment of acne vulgaris poses a challenge to the dermatologist, and the disease causes emotional anxiety for the patient. The treatment of acne vulgaris may be well-suited to home-use applications, where sufferers may be too embarrassed to seek medical treatment. This randomized controlled study is designed to quantify the effectiveness of using a blue light device in a therapy combined with proprietary creams, in the investigation of a self-treatment regimen. A total of 41 adults with mild-to-moderate facial inflammatory acne were recruited. The subjects were randomly assigned to combination blue light therapy (n = 26) or control (n = 15). Photography was used for qualitative assessment of lesion counts, at weeks 1, 2, 4, 8, and 12. All subjects in the treatment cohort achieved a reduction in their inflammatory lesion counts after 12 weeks. The mean inflammatory lesion counts reduced by 50.02% in the treatment cohort, and increased by 2.45% in the control cohort. The reduction in inflammatory lesions was typically observable at week-3, and maximal between weeks 8 and 12. The treatment is free of pain and side-effects. The blue light device offers a valuable alternative to antibiotics and potentially irritating topical treatments. Blue light phototherapy, using a narrow-band LED light source, appears to be a safe and effective additional therapy for mild to moderate acne.

BACKGROUND:Stomatitis is a common consequence of chemotherapy and a condition for which there is little effective treatment. Although the management of patients with other chemotherapy-related toxicities has improved in recent years, the incidence of stomatitis is increasing because of more intensive treatment and is often a dose limiting factor in chemotherapy. The authors assessed the efficacy of a homeopathic remedy, TRAUMEEL S(R), in the management of chemotherapy-induced stomatitis in children undergoing bone marrow transplantation.

METHODS:A randomized, placebo-controlled, double-blind clinical trial was conducted in 32 patients ages 3-25 years who had undergone allogeneic (16 patients) or autologous (16 patients) stem cell transplantation. Of the 30 evaluable patients, 15 were assigned placebo, and 15 were assigned TRAUMEEL S both as a mouth rinse, administered five times daily from 2 days after transplantation for a minimum of 14 days, or until at least 2 days after all signs of stomatitis were absent. Stomatitis scores were evaluated according to the World Health Organization grading system for mucositis.

RESULTS:A total of five patients (33%) in the TRAUMEEL S treatment group did not develop stomatitis compared with only one patient (7%) in the placebo group. Stomatitis worsened in only 7 patients (47%) in the TRAUMEEL S treatment group compared with 14 patients (93%) in the placebo group. The mean area under the curve stomatitis scores were 10.4 in the TRAUMEEL S treatment group and 24.3 in the placebo group. This difference was statistically significant (P<0.01).

CONCLUSIONS:This study indicates that TRAUMEEL S may reduce significantly the severity and duration of chemotherapy-induced stomatitis in children undergoing bone marrow transplantation.

Sterile inflammation occurs when inflammatory proteins are increased in blood and tissues by nonpathogenic states and is a double-edged sword depending on its cause (stress, injury, or disease), duration (transient versus chronic), and inflammatory milieu. Short-term fasting can exert a host of health benefits through unknown mechanisms. The following experiment tested if a 24 h fast would modulate basal and stress-evoked sterile inflammation in plasma and adipose. Adult male F344 rats were either randomized to ad libitum access to food or fasted for 24 h prior to 0 (control), 10, or 100, 1.5 mA-5 s intermittent, inescapable tail shocks (IS). Glucose, nonesterified free fatty acids (NEFAs), insulin, leptin, and corticosterone were measured in plasma and tumor necrosis factor- (TNF-) α, interleukin- (IL-) 1β, IL-6, and IL-10 in plasma, and subcutaneous, intraperitoneal, and visceral compartments of white adipose tissue (WAT). In control rats, a 24 h fastreduced all measured basal cytokines in plasma and visceral WAT, IL-1β and IL-6 in subcutaneous WAT, and IL-6 in intraperitoneal WAT. In stressed rats (IS), fasting reduced visceral WAT TNF-α, subcutaneous WAT IL-1β, and plasma insulin and leptin. Short-term fasting may thus prove to be a usefuldietary strategy for reducing peripheral inflammatory states associated with visceral obesity and chronic stress.

There is considerable support for the view that aerobic exercise may confer cognitive benefits to mild cognitively impaired elderly persons. However, the biological mechanisms mediating these effects are not entirely clear. As a preliminary step towards informing this gap in knowledge, we enrolled older adults confirmed to have mild cognitive impairment (MCI) in a 6-month exercise program. Male and female subjects were randomized into a 6-month program of either aerobic or stretch (control) exercise. Data collected from the first 10 completers, aerobic exercise (n=5) or stretch (control) exercise (n=5), were used to determine intervention-induced changes in the global gene expression profiles of the aerobic and stretch groups. Using microarray, we identified genes with altered expression (relative to baseline values) in response to the 6-month exercise intervention. Genes whose expression were altered by at least two-fold, and met the p-value cutoff of 0.01 were inputted into the Ingenuity Pathway Knowledge Base Library to generate gene-interaction networks. After a 6-month aerobic exercise-training, genes promoting inflammation became down-regulated, whereas genes having anti-inflammatory properties and those modulating immune function or promoting neuron survival and axon growth, became up-regulated (all fold change≥±2.0, p<0.01). These changes were not observed in the stretch group. Importantly, the differences in the expression profiles correlated with significant improvement in maximal oxygen uptake (VO2max) in the aerobic program as opposed to the stretch group. We conclude that three distinct cellular pathways may collectively influence the training effects of aerobic exercise in MCI subjects. We plan to confirm these effects using rt-PCR and correlate such changes with the cognitive phenotype.

BACKGROUND:It is important to manage inflammation after craniotomy. It may be prudent to reduce the excessive usage of antibiotics and to add supplementary treatments like acupuncture, which would be effective and safe. However, there are only a few studies available to date on the effects of acupuncture on anti-inflammatory response after craniotomy. The aim of this study was to explore the anti-inflammatory effects of acupuncture in patients after a craniotomy.

METHODS:This study was a single-center, prospective, open-label, controlled trial. Forty-four subjects who underwent craniotomy for an unruptured aneurysm, facial spasm, or brain tumor were allocated to either an acupuncture group or a control group. Both groups received postoperative routine care in the Department of Neurosurgery. The subjects in the acupuncture group also received a total of 6 acupuncture treatments sessions within 8 days after craniotomy. Acupuncture treatments included acupuncture, electroacupuncture, and intradermal acupuncture. The serum interleukin (IL)-1β and IL-6, tumor necrosis factor-α (TNF-α), C-reactive protein (CRP), and erythrocyte sedimentation rate levels were assessed four times within 7 days after surgery. The presence of fever, use of additional antibiotics, presence of infection including pneumonia or urinary tract infection, and safety were also reviewed.

RESULTS:The IL-1β levels of subjects who underwent aneurysmal clipping were significantly lower in the acupuncture group (P = .02). TNF-α levels of subjects who underwent aneurysmal clipping at the seventh postoperative day were also significantly lower in the acupuncture group (P = .03). Six cases of fever of unknown origin were observed in the control group, while none were seen in the acupuncture group, revealing that the incidence of fever was significantly lower in the acupuncture group (P = .02). No adverse events occurred during the trial.

CONCLUSION:Acupuncture showed a possibility of alleviating inflammation by attenuating the levels of proinflammatory cytokines and significantly reduced the incidence of fever of unknown origin in patients after craniotomy. Acupuncture would be suitable as an adjunctive therapy to alleviate inflammation after craniotomy.

BACKGROUND The aim of this pragmatic study was to explore the intervention of acupuncture combined with hydrotherapy and perceived effects in type 2 diabetic patients with recently diagnosed, mild, lower-extremity arterial disease (LEAD) in comparison with a control group. MATERIAL AND METHODS One hundred twenty-six diabetes patients who were diagnosed mild LEAD according to ankle-brachial blood pressure index (ABPI) and peripheral neuropathy symptom were randomly assigned to either an experimental (n=64) or control group (n=62). The experimental group attended and completed (1) a 30-min session of acupuncture in certain selected points, and (2) a 30-min hydrotherapy exercise every 2 days for 15 weeks. The outcome parameters were assessed at baseline, after intervention, and at 6-week follow-up. RESULTS The intervention was associated with an improvement in leg flow conductance and partial physical capacities, including chair-sit-and-reach, the walking impairment questionnaire (WIQ), and physical component summary score (PCS), compared to the control group. The treatment benefits were sustained throughout the 6-week follow-up endpoint. There was no difference in fasting glucose levels, Hb1Ac, blood pressure, or BMI after the intervention. At the endpoint of 6-week follow-up, acupuncture plus hydrotherapy appeared to reduce inflammatory response by decreasing IL-6, TNF-α, malondialdehyde, and SOD, and increasing glutathione. CONCLUSIONS Acupuncture plus hydrotherapy, without significant glycemic-controlling effects in the type 2 diabetic patients with mild LEAD, exerts a measurable benefit in disease-specific physical functions and health-related quality of life.Our results suggest that the combined therapy regulates the inflammatory process and oxidative stress and contributes to immune protection.

AIMS:Oxidative stress and inflammation have been implicated in the pathogenesis of vascular dementia (VD). Thioredoxin-interacting protein (TXNIP) plays a vital role in oxidative stress and NOD-like receptor protein 3 (NLRP3) inflammasome activation. There is evidence that acupuncture has an antioxidative and neuroprotective effect in VD. In this study, we investigated whether acupuncture can attenuate cognitive impairment via inhibiting TXNIP-associated oxidative stress and inflammation in VD rats.

METHODS:Both common carotid arteries were occluded (2-vessel occlusion [2VO]) in rats to model VD. The neuroprotective effect of acupuncture was assessed by the Morris water maze and Nissl staining. Oxidative stress was assessed by detecting levels of reactive oxygen species, DNA oxidation, and antioxidase. Western blot, real-time PCR, and immunofluorescence were used to detect the expression of TXNIP, NLRP3, caspase-1, and IL-1β. A TXNIP siRNA intraventricular injection was applied to investigate whether acupuncture mimicked the effect of TXNIP inhibitor.

RESULTS:Our findings demonstrated that VD rats treated with acupuncture had reduced hippocampal neuronal loss and oxidative stress. The upregulation of TXNIP, NLRP3, caspase-1, and IL-1β induced by 2VO was also reversed by acupuncture. Furthermore, TXNIP siRNA had a similar effect as acupuncture on cognition, hippocampal neurons, and ROS production in VD rats.

CONCLUSION:In conclusion, our study suggests that the neuroprotective effects of acupuncture in VD are mediated through reducing expression of TXNIP-associated oxidative stress and inflammation.

Chronic heart failure (CHF), a clinical syndrome resulting from the consequences of various cardiovascular diseases (CVDs), is increasingly becoming a global cause of morbidity and mortality. We had earlier demonstrated that a 4-day forest bathing trip can provide an adjunctive therapeutic influence on patients with CHF. To further investigate the duration of the impact and the optimal frequency of forest bathing trips in patients with CHF, we recruited those subjects who had experienced the first forest bathing trip again after 4 weeks and randomly categorized them into two groups, namely, the urban control group (city) and the forest bathing group (forest). After a second 4-day forest bathing trip, we observed a steady decline in the brain natriuretic peptide levels, a biomarker of heart failure, and an attenuated inflammatory response as well as oxidative stress. Thus, this exploratory study demonstrated the additive benefits of twice forest bathing trips in elderly patients with CHF, which could further pave the way for analyzing the effects of such interventions in CVDs.

Necrotizing ulcerative gingivitis (NUG) is a microbial disease of the gingiva in the context of an impaired host response. This form of gingivitis is relatively rare. NUG is an infection characterized by gingival necrosis presenting as"punched-out"papillae, spontaneous bleeding, pain, oral malodor, and pseudomembrane formation. The primary predisposing factors are bacterial plaque and an inadequate diet, but smoking and psychological stress may also affect the disease severity. NUG is associated with a characteristic bacterial flora, which includes fusiform bacteria, spirochetes, and Prevotella intermedia. Conventional treatment includes control of both the bacterial plaque and the secondary factors, as well as topical or systemic treatment biostimulative effect on wound healing, pain control, and inflammatory processes. Patients with NUG were treated using adjunct use of a diode laser (980 nm) for the control of pain and to accelerate the wound healing at day 2. 3. 5. 9, energy density was 9 J/cm. After treatment, the patients' quality of life improved faster than with conventional treatment. These results suggest that low-level laser therapy (LLLT) is an effective treatment for the reduction of pain levels and healing times. As a result, our case report shows that LLTT has a positive effect in relieving the symptoms of NUG.

Aerobic exercise (AE) reduces lung function decline and risk of exacerbations in asthmatic patients. However, the inflammatory lung response involved in exercise during the sensitization remains unclear. Therefore, we evaluated the effects of exercise for 2 weeks in an experimental model of sensitization and single ovalbumin-challenge. Mice were divided into 4 groups: mice non-sensitized and not submitted to exercise (Sedentary, n=10); mice non-sensitized and submitted to exercise (Exercise, n=10); mice sensitized and exposed to ovalbumin (OVA, n=10); and mice sensitized, submitted to exercise and exposed to OVA (OVA+Exercise, n=10). 24 h after the OVA/saline exposure, we counted inflammatory cells from bronchoalveolar fluid (BALF), lung levels of total IgE, IL-4, IL-5, IL-10 and IL-1ra, measurements of OVA-specific IgG1 and IgE, and VEGF and NOS-2 expression via western blotting. AE reduced cell counts from BALF in the OVA group (p<0.05), total IgE, IL-4 and IL-5 lung levels and OVA-specific IgE and IgG1 titers (p<0.05). There was an increase of NOS-2 expression, IL-10 and IL-1ra lung levels in the OVA groups (p<0.05). Our results showed that AE attenuated the acute lung inflammation, suggesting immunomodulatory properties on the sensitization process in the early phases of antigen presentation in asthma.

White adipose tissue (WAT) is no longer considered a tissue whose main function is the storage of TAG. Since the discovery of leptin in 1994, several studies have elucidated the important role of WAT as an endocrine organ, the source of the adipokines. The low-grade inflammation observed in obese and cancer cachexia patients is explained, at least partially, by the exacerbated release of proinflammatory adipokines. Despite of the recent progress in the characterization of the various adipokines and lipokines produced by WAT, little is known about the mechanisms regulating the secretion of these molecules in different physiological and pathological circumstances. Chronic exercise is a nonpharmacological therapy employed in several chronic diseases and shows an anti-inflammatory effect through the regulation of the cytokine network. In this review, we address the potential mechanisms by which the aerobic physical exercise modulate the production and release of inflammatory adipokines, as well as the inflammation-lipolysis axis in WAT, with special focus in the therapeutic role of exercise in obesity-associated insulin resistance and cancer cachexia.

BACKGROUND:Mindfulness meditation training interventions have been shown to improve markers of health, but the underlying neurobiological mechanisms are not known. Building on initial cross-sectional research showing that mindfulness meditation may increase default mode network (DMN) resting-state functional connectivity (rsFC) with regions important in top-down executive control (dorsolateral prefrontal cortex [dlPFC]), here we test whether mindfulness meditation training increases DMN-dlPFC rsFC and whether these rsFC alterations prospectively explain improvements in interleukin (IL)-6 in a randomized controlled trial.

METHODS:Stressed job-seeking unemployed community adults (n = 35) were randomized to either a 3-day intensive residential mindfulness meditation or relaxation training program. Participants completed a 5-minute resting-state scan before and after the intervention program. Participants also provided blood samples at preintervention and at 4-month follow-up, which were assayed for circulating IL-6, a biomarker of systemic inflammation.

RESULTS:We tested for alterations in DMN rsFC using a posterior cingulate cortex seed-based analysis and found that mindfulness meditation training, and not relaxation training, increased posterior cingulate cortex rsFC with left dlPFC (p<.05, corrected). These pretraining to posttraining alterations in posterior cingulate cortex-dlPFC rsFC statistically mediated mindfulness meditation training improvements in IL-6 at 4-month follow-up. Specifically, these alterations in rsFC statistically explained 30% of the overall mindfulness meditation training effects on IL-6 at follow-up.

CONCLUSIONS:These findings provide the first evidence that mindfulness meditation training functionally couples the DMN with a region known to be important in top-down executive control at rest (left dlPFC), which, in turn, is associated with improvements in a marker of inflammatory disease risk.

Visceral adipose tissue is an immunogenic tissue, which turns detrimental during obesity by activation of proinflammatory macrophages. During aging, chronic inflammation increases proportional to visceral adipose tissue (VAT) mass and associates with escalating morbidity and mortality. Here, we utilize a mouse model to investigate the inflammatory status of visceral adipose tissue in lean aging mice and assess the effects of exercise training interventions. We randomized adult (11 months; n = 21) and old (23 months; n = 27) mice to resistance training (RT) or endurance training (ET), or to a sedentary control group (S). Strikingly, we observed an anti-inflammatory phenotype in the old mice, consisting of higher accumulation of M2 macrophages and IL-10 expression, compared to the adult mice. In concordance, old mice also had less VAT mass and smaller adipocytes compared to adult mice. In both age groups, exercise training enhanced the anti-inflammatory phenotype and increased PGC1-α mRNA expression. Intriguingly, the brown adipose tissue marker UCP1 was modestly higher in old mice, while remained unchanged by the intervention. In conclusion, in the absence of obesity, visceral adipose tissue possesses a pronounced anti-inflammatory phenotype during aging which is further enhanced by exercise.

BACKGROUND:Low-grade chronic inflammation in overweight subjects is thought to play an important role in disease development.

OBJECTIVE:It was hypothesized that specific dietary components are able to reduce low-grade inflammation as well as metabolic and oxidative stress.

DESIGN:Dietary products [resveratrol, green tea extract, alpha-tocopherol, vitamin C, n-3 (omega-3) polyunsaturated fatty acids, and tomato extract] selected for their evidence-based antiinflammatory properties were combined and given as supplements to 36 healthy overweight men with mildly elevated plasma C-reactive protein concentrations in a double-blind, placebo-controlled, crossover study with treatment periods of 5 wk. Inflammatory and oxidative stress defense markers were quantified in plasma and urine. Furthermore, 120 plasma proteins, 274 plasma metabolites (lipids, free fatty acids, and polar compounds), and the transcriptomes of peripheral blood mononuclear cells and adipose tissue were quantified.

RESULTS:Plasma adiponectin concentrations increased by 7%, whereas C-reactive protein (principal inflammation marker) was unchanged. However, a multitude of subtle changes were detected by an integrated analysis of the "omics" data, which indicated modulated inflammation of adipose tissue, improved endothelial function, affected oxidative stress, and increased liver fatty acid oxidation.

CONCLUSION:An intervention with selected dietary products affected inflammatory processes, oxidative stress, and metabolism in humans, as shown by large-scale profiling of genes, proteins, and metabolites in plasma, urine, and adipose tissue. This trial was registered at clinical trials.gov as NCT00655798.

Eucalyptus globulus possesses important pharmacological activities, including antioxidant and anti-inflammatory effects. We investigated the anti-fatigue, antioxidant, and anti-inflammatory effects of eucalyptus essential oil after swimming exercise using an animal model. Male Sprague– Dawley rats were administered eucalyptus oil (200 μL/h) daily via inhalation (15 min), and anti-fatigue effects were assessed following eucalyptus essential oil administration for 2 or 4 weeks when forced to swim until exhaustion while carrying ~5% body weight-equivalent. To assess antioxidantand anti-inflammatory effects, control and oil-treated groups were subjected to swimming, which was intensified from 90 min to 120 min daily over 4 weeks, with non-swimming groups included as controls. The 2- and 4-week-treated rats increased their swimming-to-exhaustion time by 46 s and 111 s, respectively. Additionally, lactate (LA), creatine kinase (CK), and lactate dehydrogenase (LDH) activities increased significantly in the non-treated swimming relative to levels observed in the non-swimming groups (P<0.05); however, no significant differences in these markers were observed between the treated groups. The anti-fatigue effects were related to LA clearance and reduced LDH and CK concentrations. Moreover, compared to the corresponding levels in the non-swimmers, the non-treated swimmers showed markedly elevated levels of liver malondialdehyde (MDA), xanthine oxidase (XO), and other factors, but significantly decreased (P<0.05) glutathione (GSH) concentrations. However, compared with that of the non-swimmer group, the treated swimming group showed no significant changes in these levels (P>0.05), suggesting stable XO and MDA production and maintenance of GSH levels. These results suggested that eucalyptus oil aromatherapy increased rat swimming performance and antioxidant capacity and decreased oxidative damage and inflammatory reactions in tissues, indicating good anti-fatigue, antioxidant, and anti-inflammatory effects after high-intensity endurance exercise.

The anti-inflammatory effect of Arnica montana 6cH was evaluated using acute and chronic inflammation models. In the acute, model, carrageenin-induced rat paw oedema, the group treated with Arnica montana 6cH showed 30% inhibition compared to control (P<0.05). Treatment with Arnica 6cH, 30 min prior to carrageenin, did not produce any inhibition of the inflammatory process. In the chronic model, Nystatin-induced oedema, the group treated 3 days previously with Arnica montana 6cH had reduced inflammation 6 h after the inflammatory agent was applied (P<0.05). When treatment was given 6 h after Nystatin treatment, there was no significant inhibitory effect. In a model based on histamine-induced increase of vascular permeability, pretreatment with Arnica montana 6cH blocked the action of histamine in increasing vascular permeability.
