Inflammatory Action

Protein glycation and oxidative stress lead to severe health complications in various diseases including diabetes mellitus. The intake of flavonoid-rich foods has been confirmed previously to have a positive effect on human health. Ginger is an important source of flavonoids and is one of the most widely used traditional medicines in many Asian countries. The aim of this study was to verify the therapeutic potential of methanolic extract from ginger against glycation and other oxidative stress-induced complications using in vitro study. In this study, quantitative estimations of antioxidant components such as total phenolic and flavonoids were determined by UV–visible spectrophotometry. The anti-inflammatory action of the ginger extract was checked by determining its protective action against the denaturation of proteins, anti-proteinase activity and its membrane stabilization effect. The anti-inflammatory action of ginger extract was found to be comparable with reference standard drugs. The antiglycating effect of ginger extract was investigated by placing bovine serum albumin (BSA) with glucose in the presence and absence of ginger extract for two weeks at 37 °C. The incubated samples were analyzed for the number of glycation products, secondary structural changes, aggregation and advanced glycation end products (AGEs) formation by checking browning intensity, determination of aggregation index and Congo red assays. Our findings demonstrated that ginger extract (600 µg/mL) significantly reduced the browning, secondary structural changes, aggregation and AGEs formation. Thus, it can be concluded from these results that ginger extract is a wealthy source of antioxidants and can be used to prevent the glycation and oxidative stress-induced damage of biomolecules in various health complications including inflammation.

The objective of this in vitro study was to evaluate the influence of remineralizing agents on the surface roughness of eroded tooth enamel. Forty incisive bovines were selected and sectioned to obtain specimens of 4mm X 4mm, resulting in a surface area of 16,00mm², with a thickness of 2.50mm. The specimens were immersed in lemon juice, twice a day, over 5 days, and randomly divided into the following 4 groups: G1 = No treatment; G2 = 1.23% APF; G3 = Fluoride Varnish 5% and G4 = Regenerated. The surface roughness of the specimens was analyzed by means of confocal laser scanning microscopy. The obtained data were submitted to ANOVA after attend the homogeneity (Levene´s) and normality tests (Kolmogorov-Smirnov). All tests were statistically significant at 5% (α=0.05). The results showed that there was no statistically significant difference on the enamel roughness surface area between groups in the experimental region and the founded values were higher at the experimental when compared to the control region, however, without differences between the groups in each region. It was concluded that the remineralizing agents were not able to reduce the surface roughness of the studied groups.   Keywords: Tooth Erosion. Dental Enamel. Fluorine. Tooth Remineralization. Resumo O objetivo deste estudo in vitro foi avaliar a influência de agentes remineralizantes na rugosidade da superficial do esmalte dental erodido. Quarenta bovinos incisivos foram selecionados e seccionados para obter espécimes de 4 mm x 4 mm, resultando em uma área superficial de 16,00 mm², com espessura de 2,50 mm. As amostras foram imersas em suco de limão, duas vezes ao dia, durante 5 dias, e divididas aleatoriamente nos 4 grupos seguintes: G1 = Sem tratamento; G2 = Flúor gel 1,23%; G3 = Verniz fluoretado 5% e G4 =Regenerate. A rugosidade superficial das amostras foi analisada por microscopia confocal de varredura a laser. Os dados obtidos foram submetidos à ANOVA após os testes de homogeneidade (Levene) e normalidade (Kolmogorov-Smirnov). Todos os testes foram estatisticamente significantes a 5% (α = 0,05). Os resultados mostraram que não houve diferença estatisticamente significante na rugosidade de área do esmalte entre os grupos na região experimental e os valores encontrados foram maiores na experimental quando comparados à região controle, no entanto, sem diferenças entre os grupos em cada região. Concluiu-se que os remineralizantes não foram capazes de reduzir a rugosidade da superfície dos grupos estudados. Palavras-chave: Erosão Dentária. Esmalte dentário. Flúor. Remineralização Dentária.
