In 1969, a Canadian laboratory announced that its studies on synthetic alkaline (cyclamate) proved to be a carcinogen despite its use for more than twenty years in the beverage industry. There are many additives that have raised the controversy about the large extent of safety to consumers and the most famous controversy and consumption is the article of monosodium glutamate (MSG) which touched research on the negative impact on samples of research experiments. This research aims to study the effect (MSG) on the formation of retina in chicken embryos and the potential improvement effects of GSE grape seed extracts during incubation as part of the solutions provided in the event of the long term use of MSG and its accumulation in the body Human. The experimental groups were divided into 4 groups based on the injection period and the injected substances. The first control group(Injected with saline), the second group, treated with  MSG, the 3rd group were treated with Monosoudim glutamate and grape seed extract at days 0,1 of incubation, whereas the 4thgroup,was treated with MSG and then the GSE (M – G) were given at3,4 days post MSG . The effect of the experimental materials on the development of the retina at the age of 14 was investigated in the current work. The results showed that the treatment of embryos with MSG dose (0.1 ml) caused many of the abnormalities at the level of tissue formation of the retina, and after the treatment of the fetus with GSE was noted to reduce the damage to the tissue of the retina. The results showed that the treatment of embryos with MSG dose (0.1 ml) caused many of the abnormalities at the level of tissue form of the retina, and after the treatment of the fetus with GSE was noted to reduce the damage to the tissue of the retina.

  Excessive continuous noises exposure changes the male hormone system which leads to formation of oxidative stress and results in disrupt of semen quality. This condition can be reduced by the use of antioxidants. Grape seed is one of the antioxidants that contains phenol components that have Resveratrol compounds. This research aimed to observe the effect of noise exposure on the number of spermatozoa of male mice given grape seed extract. The method of the research was a post-test only control group design with research subjects of 30 male Mus musculus L. (Swiss Webster) mice divided into 5 groups: group A (treatment control) was not given noise exposure and grape seed extract, group B (negative control) was not given noise exposure and was given grape seed extract, groups C, D, E (treatment group) were given noise exposure with sequential intensities of 65 dB, 85 dB, 105 dB. The treatment was given for 33 days. The results showed that noise exposure with different intensities of 65 dB, 85 dB, 105 dB reduced the spermatozoa count of male Swiss Webster mice even with the administration of grape seed extract. One Way Anova test was used to analyze the data with p-value of 0.001. Conclusion: There were differences in spermatozoa count between the control group and the treatment group. Provision of noise exposure with a value above the threshold limit reduces the number of male Swiss Webster mice spermatozoa given with grape seed extract.

Background: Melasma is a common hyperpigmentation disorder, characterized by light-to-dark brown patches, usually distributed on sun-exposed areas of the body. The objective of this study was to evaluate the efficacy and tolerability of an oral nutritional supplement containing Pinus pinaster and Grape seed extract, vitamins and minerals, used concomitantly with a high SPF sunscreen in 30 women with mild-to-moderate facial melasma. Methods: Efficacy was assessed by measurement of the Melasma Area and Severity Index (MASI), instrumental analysis of the lesions (Mexameter®, VISIA®)) and Patient’s and Physician’s Global Assessment (PGA). Results: The MASI score decreased significantly compared with baseline at days 28, 56, and 84. Mexameter® analysis showed a significant decrease of ∆M (difference in the melanin index between melasma and adjacent area). VISIA® results also showed a reduction in the number and areas of UV pigmented spots and in the areas of melasma overtime. Both the Patient’s and Physician’s Global Assessment showed that the product led to an improvement of the lesions in terms of depigmentation and had positive cosmetic features without adverse events. Conclusion: The oral supplement subject of this study in combination with high SPF sunscreen was effective and well-tolerated for treatment of mild to moderate facial melasma.

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.

Effects of GSE and vitamins C and E on aspirin- and ethanol-induced gastric ulcer and associated increases of lipid peroxidation in rats were compared. Two experiments were conducted. Rats were randomized into eight groups: a negative control and seven groups that received aspirin or ethanol for ulcer induction: one positive control (vehicle) and six with VC, VE, or GSE (25 and 250 mg/kg). Ulcer indexes and gastric levels of malondialdehyde (MDA) were quantified. VC, VE, and GSE (25 and 250 mg/kg) decreased aspirin, and ethanol-induced ulcers and MDA values compared with positive control group. The magnitude of aspirin ulcer reduction was comparable for all treatments, and MDA decrease with GSE was higher than with VC and tended to be greater, albeit none significantly, than with VE. GSE was more effective than VC and VE for lowering the ethanol ulcers, while the decrease of MDA levels with GSE was greater than with VC, but comparable to that achieved with VE. GSE protected against ethanol-induced gastric ulcers more effectively than VC or VE, while its protection against aspirin ulcers was comparable for all treatments. GSE produced the greatest reductions of gastric MDA in both models.

Background: The risk of occupational exposure to acrylamide is high and long-term acrylamide exposure can cause neurotoxicity. Thus, therapeutic agents that can protect against acrylamide-induced neurotoxicity are needed. Objective: To investigate whether Grape Seed Extract (GSE) protects against acrylamide-induced neurotoxicity in mice. Methods: Mice were divided into saline, GSE, acrylamide, GSE followed by acrylamide, acrylamide followed by GSE, and simultaneous acrylamide and GSE treatment groups. Gene expression and antioxidant enzyme levels were then determined using RT-PCR and biochemical assays. Results: Gpx1 (P < 0.05), Prdx3 (P < 0.01), SOD1 (P < 0.05), and CAT (P < 0.05) significantly upregulated in GSE-treated mice, compared to those in untreated controls. In contrast, Gpx1 (P < 0.05), Prdx3 (P < 0.05), SOD1 (P < 0.05), and CAT (P < 0.05) significantly downregulated in acrylamide-treated mice compared to those in untreated controls. Results of the treatment with GSE before exposure to acrylamide or simultaneously with acrylamide indicated that GSE restored Gpx1, Prdx3, SOD1, and CAT expression to similar levels as those in the control group. GSE treatment after exposure to acrylamide did not exert any neuroprotective effects against acrylamide, as revealed by significant downregulation of Gpx1 (P < 0.05), Prdx3 (P < 0.01), SOD1 (P < 0.05), and CAT (P < 0.05) compared to that in untreated controls. Animals treated with grape seed before acrylamide treatment showed no significant change in LPO activities and a significant increase in GSH levels, compared to those in untreated controls. Conclusion: GSE exerted neuroprotective effects against acrylamide-induced neurotoxicity. Acrylamide caused oxidative stress 20 days post-exposure. However, grape seed treatment before exposure to acrylamide restored all test parameters to levels similar to control values.

In this study, the effects of grape seed extract on insulin, adiponectin and resistin levels in diabetic rats were aimed to investigate. Weight of about 300-350g 7-8 weeks 32 female Wistar Albino rats were used. Weight of about 300-350g 7-8 weeks 32 female Wistar Albino rats randomly divided into four groups of eight each: control group (C), group with diabetes (DM), grape seed extract group (GSE), diabetes mellitus and grape seed extract group (DM+GSE). The diabetic group 45 mg/kg single dose of streptozotocin was administered intraperitoneally, and the grape seed extract groups (DM+GSE and GSE) grape seed extract was given orally every day with an intragastric tube for 20 days (0.6 ml/rat). Blood samples were taken from the hearts of rat’s end of the experiment. The sera obtained were used for insulin, adiponectin and resistin analysis measured via ELISA with commercial kits. The insulin and adiponectin levels of the rats in the diabetes + grape seed extract group were found to be higher than those in the diabetes group. There was no significant change in the resistin level differences between the groups. As a result; It is possible to say that grape seed extract has an increasing effect on insulin level and adiponectin levels of diabetic rats are decreased due to diabetes and it has no significant effect on resistin levels. Detected by the positive effects of grape seed extracts, it may be useful to use for the regulating of the diabetes in human.

Proanthocyanidins, compounds highly concentrated in dietary fruits, such as cranberries and grapes, demonstrate significant cancer prevention potential against many types of cancer. The objective of this study was to evaluate cranberry and grape seed extracts to quantitate and compare their anti-proliferative effects on the most common type of oral cancer, oral squamous cell carcinoma. Using two well-characterized oral squamous cell carcinoma cell lines, CAL27 and SCC25, assays were performed to evaluate the effects of cranberry and grape seed extract on phenotypic behaviors of these oral cancers. The proliferation of both oral cancer cell lines was significantly inhibited by the administration of cranberry and grape seed extracts, in a dose-dependent manner. In addition, key regulators of apoptosis, caspase-2 and caspase-8, were concomitantly up-regulated by these treatments. However, cranberry and grape seed extracts elicited differential effects on cell adhesion, cell morphology, and cell cycle regulatory pathways. This study represents one of the first comparative investigations of cranberry and grape seed extracts and their anti-proliferative effects on oral cancers. Previous findings using purified proanthocyanidin from grape seed extract demonstrated more prominent growth inhibition, as well as apoptosis-inducing, properties on CAL27 cells. These observations provide evidence that cranberry and grape seed extracts not only inhibit oral cancer proliferation but also that the mechanism of this inhibition may function by triggering key apoptotic regulators in these cell lines. This information will be of benefit to researchers interested in elucidating which dietary components are central to mechanisms involved in the mediation of oral carcinogenesis and progression.

The efficacy of methotrexate (MTX), a widely used cytotoxic chemotherapeutic agent, is often limited by its severe hepatotoxicity. Regarding the mechanisms of these adverse effects, several hypotheses have been put forward, among which oxidative stress is noticeable. The present study was undertaken to determine whether grape seed extract (GSE), a new natural free radical scavenger, could ameliorate the MTX-induced oxidative injury in the rat liver. The animals were divided into 3 groups. Each group consisted of 12 animals. MTX-GSE group: rats were given GSE (100mg/kg body weight) orally for 15 days, and a single dose of MTX (20mg/kg, intraperitoneally) was added on the 10th day. MTX group: these received placebo distilled water (orally) instead of GSE for 15 days and the same MTX protocol applied to this group on the 10th day. Control group: rats were given distilled water (orally) through 15 days and physiological saline (intraperitoneally) instead of MTX was administered on the 10th day in a similar manner. On the 16th day, liver tissue samples were obtained under deep anaesthesia. The level of malondialdehyde (MDA), an end product of lipid peroxidation, and the activities of süperoxide dismutase (SOD) and catalase (CAT), two important endogenous antioxidants, were evaluated in the tissue homogenates. MTX administration increased the MDA level and decreased the SOD and CAT activities in the liver homogenates ( p < 0.001), while these alterations were significantly reversed by GSE treatment ( p < 0.001). MTX led to significantly reduced whole blood count parameters ( p < 0.05). When GSE was supplemented, no significant changes in blood count parameters were noted. It appears that GSE protects the rat liver and inhibits methotrexate-induced oxidative stress. These data indicate that GSE may be of therapeutic benefit when used with MTX.
