Abstract Objective The aim of this study was to analyze the effect of grape seed extract containing cyanidin on osteoclastogenesis (by means of receptor activator of nuclear factor-κ B ligand [RANKL] and osteoprotegerin [OPG] levels) and the number of osteoclasts during orthodontic relapse in Wistar rats. Materials and Methods This study is an in vivo quasi experimental research. A total of 32 male Wistar rats were used in the study, which were randomly split equally into two groups, grape seed (GS) and control group (CG). All rats were given an orthodontic force of 35 cN using a stainless steel 3-spin coil spring that was activated for 7 days and then conditioned to be passive. During this phase, the GS group was administered grape seed extract containing cyanidin once per day. Orthodontic appliances were removed from both groups afterward, and then the alveolar bone tissue was isolated consecutively according to observation days (days 1, 3, 7, and 14), while OPG and RANKL levels were analyzed in their gingival crevicular fluid using a specific enzyme-linked immunosorbent assay (ELISA). Tissues were then stained with hematoxylin–eosin (H&E) and observed under a light microscope to count the number of osteoclast cells. Data were analyzed statistically using an independent t-test (p < 0.05). Results The number of osteoclasts in the GS group was significantly lower than that in the CG group on all experiment days (p = 0.021; p = 0.001; p = 0.024; p = 0.001; p < 0.05). ELISA results showed that the RANKL level of the GS group was significantly lower on days 3 and 7 (p = 0.025; p = 0.039; p < 0.05), while the OPG level was significantly higher on days 1 and 3 in the GS group than in the CG group (p = 0.039; p = 0.021; p < 0.05). Conclusion Grape seed extract can prevent postorthodontic relapse movement by inhibiting osteoclastogenesis and reducing the number of osteoclasts in Wistar rats.

Cadmium (Cd) is wide-spread toxic metal that pollutes most of the vegetables, which eaten by numerous populations all over the world. The aim of the current work is to evaluate the protective and prophylactic effects of the antioxidant materials in the grape seed extract (GSE) on the hepatic intoxication induced by cadmium chloride toxic material in male Wistar rats. Male adult Wistar rats were divided into four groups. Control group fed on balanced diet and given drinking water. Group two (control positive) given CdCl2 in the dose of 0.44 mg/kg body weight (BW) by stomach tube daily. Group three given grape seed extract GSE in the dose of (100 mg/kg BW) daily by stomach tube. Finally, the fourth group gave mixture of (GSE and CdCl2) by stomach tube in the recommended dose. Blood and liver tissues were collected for further biochemical and histopathological studies. CdCl2 significantly increased the serum levels of malondialdehyde, ALT and AST. Cadmium administration decreased levels of antioxidants (Catalase, GSH-R and GSH-Px). The liver of the control positive groups which given CdCl2 showed degenerative changes in the form of vacuolar and hydropic degeneration. Congestion was evident in the central vein and proliferation of the kupffer cells. These hepatic biochemical and degenerative changes were ameliorated by the co addition of GSE.

Positive Effects

From the last decade flavonoids have become very prominent in the studies related to grapes. It has also been outlined by the recent researches that the positive effects of the constituents derived from theresidues of grapes are due to the polyphenolic compounds. Grape Seed Extract (GSE) possess a wide spectrum of medicinal features to inhibit reaction of free radicals, prevent clumping of platelets, prevent inflammation etc. Apart from that GSE have gastro-protective, hepato-protective, and cardio-protective roles. It has been reveal that the residues derived from the seeds of the grapes with enhanced flavonol constituents are important to be utilized during the conditions of fungal infections as vaginal candidiasis due to candida preventing c h a r a c t e risti c s. Du e t o t h e p r e s e n c e o f proanthocyanidins grape seeds are used as a food supplement also.

Interest in the biological role of bioactive compounds present in medicinal herbs has increased over the last years. Of particular interest are plants that have an anti-Alzheimer activities. Several plants can be useful for Alzheimer (AD) management. Such as these which have anti-inflammatory activity, acetylcholinesterase (AChE) inhibitory action, antiapoptotic, slow the aggregation of amyloid peptide and antioxidant activities. Grape seed extract (GSE) is a complex mixture of several compounds, mostly represented by polyphenols and flavonoids. Their consumption is safe and is recognized to exert several health benefits. GS flavonoids have been associated with the reduced risk of chronic diseases, we present some findings on the potential benefits of GSE for the treatment of AD.

Abstract Aim: The aim of this study was to compare the reversal of shear bond strength of composite to bleached enamel immediately after bleaching followed by application of various antioxidant solutions. Material and Methods: Seventy central incisors were divided into seven groups. Groups I and II served as unbleached and bleached controls respectively. Groups III, IV, V, VI and VII served as the experimental groups and were subjected to 37.5% hydrogen peroxide bleaching followed by 10 min application of 10% sodium ascorbate, 25% alpha-tocopherol, 6.5% grape seed extract, 5% lycopene and 5% green tea extract respectively. Following composite bonding, shear bond strength was determined and the results were analyzed using ANOVA followed by Post Hoc Multiple Comparisons test. Results: The bond strength values for Group I (positive control) were maximum and significantly different than all the other groups except Grape seed extract group (Group V). When compared to Group II (bleached control), all the groups showed significantly higher bond strength. Significant difference in the bond strength values were seen between Group III (10% sodium ascorbate) and Group V. Also values for Group V were significantly different from Group VI (5% lycopene). All the other values showed insignificantly different results. Conclusion: All the antioxidant solutions improved the shear bond strength values after bleaching but only Grape seed extract application reversed the values to the non bleached levels. Lycopene was least effective. Other antioxidants showed comparable results.
