objective: diabetes is an important risk factor for cardiovascular events. the great percent of morbidity in patients with diabetes is due to endothelial dysfunction. the present study investigated the effects of hydroalcholic extract of nigella sativa (n. sativa) on contractile and dilatation response of isolated aorta in streptozotocin (stz)-induced diabetic rat. materials and methods: rats ...
The whole plant of Biophytum petersianum was extracted with a mixture of water – alcohol (1:1) to evaluate its relaxant effect on aorta rings. In isolated Wistar rat tissue, the hydro-ethanolic extract (0.1; 0.25 and 0.5 mg/ml) non-competitively antagonized calcium chloride and high-K + - induced aorta contractions in a concentration-dependent manner. Moreover, the inhibition of noradr...
reports have shown the antioxidant, hypotensive, hypolipidemic and vasodilatory effects of grape (vitis vinifera l.) seed extract. we have recently shown the relaxatory effect of grape leaf extract on rat uterus and reduction of frog heart rate and contractility. the aim of the present study was to investigate the relaxant effect of vitis vinifera leaf hydroalcoholic extract (vlhe) on rat thora...

The present data are related to the research article entitled "Whey peptide isoleucine-tryptophan inhibits expression and activity of matrix metalloproteinase-2 in rat aorta" [1]. Here we present data on removal of endothelium from aorta, endothelium dependent aortic relaxation and inhibition of expression of pro-MMP2 by di-peptide isoleucine-tryptophan (IW). Experiments were performed in rat a...

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...
In this study we characterized the effects of the protein phosphatase (PP) type 1 and type 2A inhibitor cantharidin (Cant) and its structural analogs cantharidic acid and endothall on PP activity, force of contraction, and myosin light chain phosphorylation in rat aorta. All compounds inhibited PP activity in homogenates of rat aorta with a rank order of potency of Cant = cantharidic acid > end...
in this study, the possible involvement of l-type voltage-operated calcium channels in the vasorelaxant effect of the flavonoid quercetin was investigated, using the isolated aortic rings from normal male rats. addition of quercetin (0.1 µm-1 mm) caused a significant dose-dependent relaxation of noradrenaline (na)- and kcl-preconstricted rings and nifedipine attenuated this response, especially...
