RESUMO

BACKGROUND/AIM: This study aimed to research the effects of Harkány healing water on oxidative stress. The study was performed in a randomized, placebo-controlled, double-blind setup. PATIENTS AND METHODS: Twenty patients with psoriasis who underwent a 3-week-long inward balneotherapy-based rehabilitation were enrolled. Psoriasis Area and Severity Index (PASI) score and Malondialdehyde (MDA) - a marker of oxidative stress - were determined, on admission and before discharge. Patients were treated with dithranol. RESULTS: The mean PASI score - determined on admission and before discharge - decreased significantly after the 3-week-long rehabilitation 8.17 vs. 3.51 (p<0.001). The baseline MDA value of patients with psoriasis was significantly higher compared to controls (3.0±3.5 vs. 8.4±7.4) (p=0.018). MDA levels of patients receiving placebo water increased significantly compared to MDA levels of patients receiving healing water (p=0.049). CONCLUSION: The effectiveness of dithranol resides in the formation of reactive oxygen species. No increased oxidative stress was found in the patients treated with healing water, thus healing water seems to be protective against oxidative stress. However, further research is needed to confirm these preliminary results.

RESUMO

Polyphenols are capable of decreasing cancer risk. We examined the chemopreventive effects of a green tea (Camellia sinensis) extract, polyphenol extract (a mixture of blackberry (Rubus fruticosus), blackcurrants (Ribes nigrum), and added resveratrol phytoalexin), Chinese bayberry (Myrica rubra) extract, and a coffee (Coffea arabica) extract on 7,12-dimethylbenz[a]anthracene (DMBA) carcinogen-increased miR-134, miR-132, miR-124-1, miR-9-3, and mTOR gene expressions in the liver, spleen, and kidneys of CBA/Ca mice. The elevation was quenched significantly in the organs, except for miR-132 in the liver of the Chinese bayberry extract-consuming group, and miR-132 in the kidneys of the polyphenol-fed group. In the coffee extract-consuming group, only miR-9-3 and mTOR decreased significantly in the liver; also, miR-134 decreased significantly in the spleen, and, additionally, miR-124-1 decreased significantly in the kidney. Our results are supported by literature data, particularly the DMBA generated ROS-induced inflammatory and proliferative signal transducers, such as TNF, IL1, IL6, and NF-κB; as well as oncogenes, namely RAS and MYC. The examined chemopreventive agents, besides the obvious antioxidant and anti-inflammatory effects, mainly blocked the mentioned DMBA-activated factors and the mitogen-activated protein kinase (MAPK) as well, and, at the same time, induced PTEN as well as SIRT tumor suppressor genes.

RESUMO

The intake of carcinogenic and chemopreventive compounds are important nutritional factors related to the development of malignant tumorous diseases. Repetitive long interspersed element-1 (LINE-1) DNA methylation pattern plays a key role in both carcinogenesis and chemoprevention. In our present in vivo animal model, we examined LINE-1 DNA methylation pattern as potential biomarker in the liver, spleen and kidney of mice consuming green tea (Camellia sinensis) extract (catechins 80%), a chinese bayberry (Morella rubra) extract (myricetin 80%), a flavonoid extract (with added resveratrol) and coffee (Coffee arabica) extract. In the organs examined, carcinogen 7,12-dimethylbenz(a)anthracene (DMBA)-induced hypomethylation was prevented by all test materials except chinese bayberry extract in the kidneys. Moreover, the flavonoid extract caused significant hypermethylation in the liver compared to untreated controls and to other test materials. The tested chemopreventive substances have antioxidant, anti-inflammatory properties and regulate molecular biological signaling pathways. They increase glutathione levels, induce antioxidant enzymes, which decrease free radical damage caused by DMBA, and ultimately, they are able to increase the activity of DNA methyltransferase enzymes. Furthermore, flavonoids in the liver may inhibit the procarcinogen to carcinogen activation of DMBA through the inhibition of CYP1A1 enzyme. At the same time, paradoxically, myricetin can act as a prooxidant as a result of free radical damage, which can explain that it did not prevent hypomethylation in the kidneys. Our results demonstrated that LINE-1 DNA methylation pattern is a useful potential biomarker for detecting and monitoring carcinogenic and chemopreventive effects of dietary compounds.

RESUMO

The therapeutic effects of mineral waters have been attributed to the inorganic components alone; however, biologically active organic components are also present. We aimed to investigate whether the healing effect of Szigetvár thermal mineral water could relate to the organic matter in patients suffering from osteoarthritis of the hips and the knees. XAD macroreticular resins were used to prepare the organic fraction. Patients received a 30-min thermal water (34 °C) treatment in a bath tub, five times a week for 3 weeks. After randomization, patients were divided into three groups: tap water, mineral water, and organic fraction group. Primary outcomes were range of movement (ROM), Western Ontario and McMaster University Osteoarthritis Index (WOMAC), and visual analog scale (VAS) for pain severity, and the Short Form 36 (SF-36) questionnaire was used. These scores and indices were measured at baseline, after the last treatment, and at the end of the 3-month follow-up period. Seventy-four patients (age 67.3 ± 4.48 years) were enrolled: tap water n = 24, mineral water n = 26, and organic fraction n = 24. Treatment with the redissolved organic fraction significantly improved ROM, WOMAC, and SF-36 scores compared to the tap water. Our clinical trial provided evidence for the beneficial health effects of the organic fraction of Szigetvár medicinal water.

RESUMO

BACKGROUND AND AIMS: ß-Caryophyllene (BCP) is a plant-derived FDA approved food additive with anti-inflammatory properties. Some of its beneficial effects in vivo are reported to involve activation of cannabinoid CB2 receptors that are predominantly expressed in immune cells. Here, we evaluated the translational potential of BCP using a well-established model of chronic and binge alcohol-induced liver injury. METHODS: In this study, we investigated the effects of BCP on liver injury induced by chronic plus binge alcohol feeding in mice in vivo by using biochemical assays, real-time PCR and histology analyses. Serum and hepatic BCP levels were also determined by GC/MS. RESULTS: Chronic treatment with BCP alleviated the chronic and binge alcohol-induced liver injury and inflammation by attenuating the pro-inflammatory phenotypic `M1` switch of Kupffer cells and by decreasing the expression of vascular adhesion molecules intercellular adhesion molecule 1, E-Selectin and P-Selectin, as well as the neutrophil infiltration. It also beneficially influenced hepatic metabolic dysregulation (steatosis, protein hyperacetylation and PPAR-α signalling). These protective effects of BCP against alcohol-induced liver injury were attenuated in CB2 receptor knockout mice, indicating that the beneficial effects of this natural product in liver injury involve activation of these receptors. Following acute or chronic administration, BCP was detectable both in the serum and liver tissue homogenates but not in the brain. CONCLUSIONS: Given the safety of BCP in humans, this food additive has a high translational potential in treating or preventing hepatic injury associated with oxidative stress, inflammation and steatosis.

RESUMO

Since 1966, Szigetvár in Hungary is well recognised as a thermal spa. Many patients suffering from rheumatic diseases are treated with its thermal mineral water. Our objective was to investigate the effects of a 3-week-long outpatient balneotherapy-based rehabilitation program on patients suffering from osteoarthritis of the hips and the knees. During the treatment period, patients received a 30-min underwater jet massage in a bath tub, five times a week. One patient group received jet massage in a bath tub containing mineral water; the other group received the same treatment in tap water. Primary outcomes were measured by range of movement of the involved joints and Western Ontario and McMaster University Osteoarthritis Index (WOMAC). Visual analogue scale (VAS) was applied to measure current severity of pain. Furthermore, quality of life was assessed using the Short Form 36 questionnaire (SF-36). Range of movement (ROM) score, Western Ontario and McMaster University Osteoarthritis Index and visual analogue scale were determined before the first treatment, after the last treatment and 3 months after the last treatment. SF-36 questionnaire was filled in before the first and after the last treatment. Fifty patients (17 male, 33 female mean age 66.7 ± 4.79 years) were enrolled. After randomisation, patients were divided into two groups: tap water n = 24 and mineral water n = 26. Treatment with the thermal mineral water of Szigetvár significantly improved ROM, WOMAC scores, and SF-36-scored quality of life of the patients. Our double-blind study provided evidence for the beneficial health effects of another Hungarian thermal mineral water masking the colour, odour and pH of the tap water and mineral water.

RESUMO

BACKGROUND/AIM: This study aimed to report a balneotherapy-based psoriasis rehabilitation protocol and assess its effectivity. PATIENTS AND METHODS: Eighty psoriatic patients who underwent a 3-week-long inward balneotherapy-based rehabilitation were enrolled. Psoriasis Area and Severity Index (PASI) score and high sensitivity C-reactive protein (CRP) were determined on admission and before discharge. RESULTS: The mean PASI score and CRP level -determined on admission and before discharge-decreased significantly after the 3-week-long rehabilitation 7.15±7.3 vs. 2.62±3.05 (p<0.001) and 4.1±3.8 vs. 3.5±3.1 (p=0.026). A negative correlation was found between PASI delta and the number of spa therapies received (r=-0.228). CONCLUSION: After completing the 3-week-long spa therapy based rehabilitation, both PASI score and CRP levels showed improvement of psoriasis. The complex spa therapy used during the rehabilitation is an effective tool to reduce the symptoms of psoriasis and improve the patient's well-being.
