BACKGROUND Fruits of Vitis vinifera L., commonly known as grapes, are largely consumed worldwide because of their high nutritional and medicinal benefits. CONTEXT AND PURPOSE The present study investigated effects of V. vinifera fruits in ovalbumin-induced animal model of bronchial asthma. METHODS Male wistar rats (except group 1) were sensitized with allergen (ovalbumin, 40 mg/rat + alumin...

BACKGROUND The aerial parts of Vitis vinifera (common grape or European grape) have been widely used in Ayurveda to treat a variety of common and stress related disorders. In the present investigation, the seed extract of V. vinifera was evaluated for antistress activity in normal and stress induced rats. Furthermore, the extract was studied for nootropic activity in rats and in-vitro antioxida...

Resveratrol is a major phytoalexin produced by plants in response to various stresses and promotes disease resistance. The resistance of North American grapevine Vitis rupestris is correlated with a hypersensitive reaction (HR), while susceptible European Vitis vinifera cv. 'Pinot Noir' does not exhibit HR, but expresses basal defence. We have shown previously that in cell lines derived from th...

the yield and quality features of raisin are affected by various factors especially har-vest date and dipping solutions. combinations of different harvest date (four harvest dates) and post harvest alkaline emulsion (three alkaline solutions) were tested in vitis vi-nifera l. cv ‘paycamy’ green raisin production in kashmar, khorasan province of iran. such raisin quantitative and qualitative cha...

In previous studies, we have shown the relaxatory effect of grape leaf (Vitis vinifera) extract on isolated ileum, uterus and aorta. In rat aorta it was revealed that the NO and endothelium are involved in the relaxation induced by grape leaf extract. The aim of present study was to investigate the effect of the Vitis vinifera leaf hydroalcoholic extract (VLHE) on rat trachea precontracted by A...

The relaxatory effect of Vitis vinifera leaf extract on rat uterus has been reported and it was postulated that, the extract relaxed through the blockade of voltage dependent calcium channels. The extract also, relaxed rat aorta through NO and was dependent on the functional endothelium. In the present study, the effect of Vitis vinifera hydroalcoholic leaf extract (VHLE) on rat vas deferens pr...
