Background: Our previous findings demonstrated that in vitro supplementation of polyphenols, extracted from seeds of red grape (Nero di Troia cultivar), to peripheral lymphomonocytes from patients affected by allergic contact dermatitis (ACD) to nickel (Ni) could reduce release of pro-inflammatory cytokines and nitric oxide (NO), while increasing levels of interleukin (IL)-10, an anti-inflammatory cytokine. Objective: To assess whether an intervention with oral administration of polyphenols leads to a reduction of peripheral biomarkers in ACD patients. Method: At T0, 25 patients affected by ACD to Ni were orally administered with 300 mg polyphenols prodie extracted from seeds of red grape (Nero di Troia cultivar) (NATUR-OX®) for 3 months (T1). Other 25 patients affected by ACD to Ni received placebo only for the same period of time. Serum biomarkers were analyzed at T0 and T1. In both groups seven drop outs were recorded. Result: At T1 in comparison to T0, in treated patients, values of IFN-γ, IL-4, IL-17, PTX3 and NO decreased, while IL-10 levels increased when compared with T0 values. Conversely, in placebo-treated patients no modifications of biomarkers were evaluated at T1. Conclusion: Present laboratory data rely on the anti-oxidant, anti-inflammatory and anti-allergic properties of polyphenols.

Seed Extracts

Pumpkin seeds are commonly consumed in Greece. Although Cucurbita moschata is locally grown in Lemnos and is traditionally used in pumpkin pies, the seeds are currently discarded after consumption of the fruit flesh. The aim of the present study was to investigate the nutritional functionality of pumpkin seeds from Cucurbita moschata grown in Lemnos.Cucurbita moschatas’ seeds, raw or roasted, were appropriately extracted and the results are presented for raw versus (vs) roasted seed extracts. The phenolic content was expressed as μg gallic acid/g of seeds according to Folin-Ciocalteau assay (370.3 ± 19.1 vs 551.0 ± 22.0). Antioxidant capacity was expressed as equivalent amount for 50% scavenging in mg of seeds for DPPH (50.03 ± 5.91 vs 25.82 ± 6.77) and ABTS (17.85 ± 0.77 vs 12.77 ± 0.76) assays, and as μmol of trolox/g of seeds for FRAP (1.19 ± 0.05 vs 2.50 ± 0.23) and CUPRAC (2.13 ±0.11 vs 3.25 ± 0.06) assays. Anti-inflammatory/anti-thrombotic and anti-diabetic activities were expressed as mg of seeds for 50% inhibition of platelet activating factor (0.62 vs 0.15) and as μg of seeds for 25% inhibition of alpha-glycosidase (40.0 vs 61.0) activities respectively. Moreover, anti-atherogenic activity was expressed as the % increase in lag time of human plasma oxidation (62.7 versus 163.2)Raw and roasted pumpkin seed extracts exert anti-oxidant, anti-thrombotic/anti-inflammatory, anti-atherogenic and antidiabetic activities. Cucurbita moschata seeds may represent a novel opportunity for development of functional foods, with a local interest in Lemnos that would contribute also to the regional public health improvement.

Most of the synthetic drugs used at present as analgesic and anti-inflammatory agents cause many side effects and toxic effects. Many medicines of plant origin with analgesic and anti-inflammatory activity have been used since long time without adverse effects. The purpose of the study was to explore the anti-pyretic and anti-oxidant activity of fruits of Garcinia pedunculata. The fruit of G. pedunculata was collected from Shillong, Meghalaya and extraction is done by using methanol as a solvent. The methanol extract shows the presence of carbohydrate, glycoside, alkaloids, phenol and flavonoids. Acute anti-pyretic activity for the extract was investigated in pyrexia rat. Temperature level was determined after 1hours, 4 hours, 8 hours and 12 hours after giving the extract dose of 100mg/kg and 200mg/kg body weight, and it was found to produce a significant reduce in fever. DPPH radical scavenging activity (In-vitro anti-oxidant activity of G. pedunculata) of methanolic extract shows 38.31 as IC50 (µg/ml) whereas Ascorbic acid as standard in the same concentration shows 34.81 IC50 (µg/ml). The obtained result justified the traditional use of G. pedunculata as anti-pyretic and antioxidant purpose.

Purpose: Delineate the selected pharmacodynamics of a naturally occurring stilbene 3’-Hydroxypterostilbene. Objective: Characterize for the first time the pharmacodynamics bioactivity in several in-vitro assays with relevant roles in heart disease, inflammation, cancer, and diabetes etiology and pathophysiology. Methods: 3’-Hydroxypterostilbene was studied in in-vitro assays to identify possible bioactivity. Results: 3’-Hydroxypterostilbene demonstrated anti-oxidant, anti-inflammatory, cytotoxic, anti-adipogenic, histone deacetylase, and sirtuin-1 inhibitory activity. Conclusions: The importance of understanding individual stilbene pharmacologic activities were delineated.  Small changes in chemical structure of stilbene compounds result in significant pharmacodynamic differences. This article is open to POST-PUBLICATION REVIEW.

In this study, the anti-oxidant and anti-inflammatory efficacy of ozone oxidative preconditioning (OOP) were investigated on hydrogen peroxide (H2O2)-induced human lung alveolar cells. In MTT and trypan blue viability tests, while 100 μmol/L H2O2caused a 17.3% and 21.9% decrease in the number of living cells, respectively, ozone at 20 μmol/L regenerated cell proliferation and prevented 9.6% and 11.0% of cell loss, respectively. In addition, H2O2decreased the transcription levels of catalase (CAT), glutathione peroxidase (GPx), and superoxide dismutase (SOD) 5.43-, 2.89-, and 5.33-fold, respectively, while it increased Bax, NF-κβ, TNF-α, and iNOS expression 1.57-, 1.32-, 1.40-, and 1.41-fold, respectively. Ozone pretreatment, however, increased CAT, GPx, and SOD transcription levels 7.08-, 5.17-, and 6.49-fold and decreased Bax, NF-κβ, TNF-α, and iNOS transcriptions by 1.25-, 0.76-, 3.63-, and 7.91-fold, respectively. Moreover, intracellular glutathione (GSH) level and SOD activity were decreased by 46.2% and 45.0% in the H2O2treatment group, and OOP recovered 58.5% and 20.1% of the decreases caused by H2O2. H2O2also increased nitrite levels 7.84-fold, and OOP reduced this increase by half. Consequently, OOP demonstrated potent anti-oxidant and anti-inflammatory effects on in vitro model of oxidative stress-induced lung injury.
