Objective: To evaluate the influence of combination of Grape seed extract and Zincovit tablets (nutritional food supplement) on blood glucose level in normal and streptozocin induced diabetic rats. Method: A total of 48 adult male Wistar rats (24 normal rats, 24 diabetic surviving rats) were divided into 8 groups of 6 rats each. Experimental hyperglycemia was produced in rats by single dose of ...

Grape seed extract (GSE) has in vitro antioxidant activity but whether or not it works in vivo is not clear. In a fully randomised, crossover trial with 4-week treatment periods on 36 men and women with above-average vascular risk, we aimed to demonstrate that 2 g/day of GSE (1 g of polyphenols) alone, or with 1 g/day of added quercetin in yoghurt, favourably alters vascular function, endotheli...

OBJECTIVES Myringosclerosis is an irreversible pathological healing mechanism of the tympanic membrane which can result in the formation of sclerotic plaques. Antioxidant treatment is a recognised prevention therapy and coenzyme Q10 (CoQ10), lycopene, and grape seed extract (GSE), were used in this manner. METHODS Forty-four Wistar rats were used in this experiment, and, following myringotomi...

Additional approaches to control malignancies are needed due to the emerging trends in the incidence of cancer of different organ sites. Due to the high frequency of hepatocellular carcinoma (HCC) and its poor prognosis, preventing HCC is an urgent priority. To explore the antioxidant and apoptotic pathways of grape seed extract (GSE) we induce HCC experimentally by diethylnitrosoamine (DEN) an...

SCOPE This work aims to evaluate changes in the fecal metabolomic profile due to grape seed extract (GSE) intake by untargeted and targeted analysis using high resolution mass spectrometry in conjunction with multivariate statistics. METHODS AND RESULTS An intervention study with six crossbred female pigs was performed. The pigs followed a standard diet for 3 days, then they were fed with a s...

The aim of the present study was to assess the anti-obesity effects of grape seed extract (GSE) supplement in C57BL/6J mice. Thirty mice were divided into three groups; normal diet control group (ND), high fat diet control group (HD) and high fat diet plus grape seed extract supplemented group (HD+GSE). Results were as follows: 1. GSE supplement reduced the weight gain in mice fed high fat diet...

Natural dietary antioxidants are studied for their ability to protect cells from miscellaneous damage. Grape seed extract (Vitis vinifera L., Vitacease) is a potent antioxidant. The present study aimed to investigate the protective effect of grape seed extract (GSE) against the possible testicular dysfunction caused by aluminium chloride (AlCl3) in male rats. Twenty sexually mature male albino ...

Background: Fluoxetine, a selective serotonin reuptake inhibitor, has been prescribed for the treatment of depression and has shown also efficacy in the treatment of bulimia nervosa and obsessive-compulsive disorder. Grape seed extract is a natural extract from the seeds of graps. It contains the most beneficial groups of plant flavonoids, proanthocyanidins oligomers. These flavonoids are poten...

Ionizing radiation (IR) causes oxidative stress through overwhelming generation of reactive oxygen species (ROS) in the living cells leading the oxidative damage further to biomolecules. Grapevine (Vitis vinifera L.) posses several bioactive phytochemicals and is the richest source of antioxidants. In this study, we investigated V. vinifera for its phytochemical content, enzymes profile and, RO...

Interactions between fungi occur when they grow on the same host plant. This is the case of Botrytis cinerea and Penicillium expansum on grape. P. expansum is also responsible for production of the mycotoxin patulin. In this study, the influence of the interaction between both fungi on fungal growth parameters was studied as well as the effect on the accumulation of patulin by P. expansum. For ...
