Because of the side-effects of commonly used anti-platelet and anticoagulant drugs, investigations into plant substances with similar activities are very common. Based on our own studies in recent years, we estimate that it is possible to use natural compounds to both inhibit coagulation pathway enzymes and to reduce blood platelets’ activation. As such, in our current study we wanted to verify the anti-platelet and anticoagulant properties of grape seed extract (GSE) using in vitro models. During our analysis, the following parameters were analyzed: Coagulation times, thromboelastometry assays (coagulation time, clot formation time and maximum clot firmness), aggregation of platelets and phosphorylation of vasodilator-stimulated phosphoprotein (VASP). Adenosine diphosphate (ADP)-induced aggregation was lower in GSE 7.5 µg/mL as well as in GSE 15.0 µg/mL. A similar dependence was observed in VASP assays for GSE 7.5 µg/mL and GSE 15 µg/mL. The effect on plasma coagulation tests was distinct only with GSE 15 µg/mL. All of the thromboelastometry variables were statistically significant with 15.0 µg/mL GSE concentration. Our results show, for the first time, the multi-potential effect of grape seed extract on coagulation systems, and clearly suggest that grape seed extract could be considered a promising nutraceutical in the prevention of cardiovascular thrombotic events caused by different mechanisms.

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 Objective Remineralization is an effective treatment that may stop or reverse early tooth decay. Grape seed extract (GSE) is the potential remineralizing agent under investigation. Materials and methods Sound human tooth sections were obtained from the cervical portion of the root and stored in demineralizing solution at 37°C for 96 hours to induce artificial root caries lesions. The sections were divided into four treatment groups including 6.5% grape seed extract, sodium monofluorophosphate (220 ppm) with 0.05% calcium glycerophosphate, 0.5% calcium glycerophosphate and control (no treatment). An in vitro pH cycling model was used to cycle the demineralized specimens through treatment solutions, acidic buffer and neutral buffer for 8 days at 6 cycles per day. Subsequently, they were evaluated using confocal laser scanning microscope. Data were analyzed using analysis of variance (p < 0.05). Results GSE revealed less demineralization and more remineralization compared with other groups. Conclusion GSE promotes remineralization of artificial root caries lesions. Clinical significance The search for the perfect remineralizing agent continues to this day. GSE could be a welcome addition to the remineralization armamentarium.

ABSTRACTObjective: Grape seeds are gaining more importance because the “Proanthocyanidins” present in them have excellent anticaries, remineralizing, andantibacterial properties. Although many preventive measures have been tried, dental caries remains one of the most prevalent diseases in humans.The ultimate goal of any intervention is the preservation of tooth structure, prevention of lesion progression and inducing remineralization. Thepresent in-vitro study was done to investigate the effect of grape seed extract (GSE) on artificial enamel caries in human teeth.Methods: A total of 50 sound premolars extracted from patients undergoing orthodontic treatment were used in the study. The teeth were cleanedand were immersed in a demineralizing solution for 96 hrs at 37°C and 50% relative humidity to create artificial lesions. The samples were randomlydivided into two groups of 25 each. Half of the samples were immersed in the GSE solution (test) and the other half in saline (control), respectively, for8 days. The samples were measured by microhardness tester to obtain values in Vickers hardness scale. Data were entered into Microsoft Excel andwere analyzed using independent t-test for inter-group comparison and paired t-test for intra-group comparison using SPSS version 21.Results: The mean±SD microhardness values after remineralization for the test and control groups were 357.56±5.53 and 337.60±6.38. GSE groupsignificantly increased the microhardness of the lesions (p≤0.001).Conclusion: GSE is a potential remineralizing agent and can be used to prevent progression of dental caries.Keywords: Grape seed extract, Remineralization, Dental caries.
