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...

Pioglitazone is a widely used anti-type 2 diabetic drug. Beside its insulin-sensitizing effects, pioglitazone exerts preventive roles against ischemic heart disease. Since one possible explanation is anti-hypertensive action, we examined effects of pioglitazone on contractility of isolated blood vessel. Endothelium-intact [End (+)] or -removed [End (-)] rat aorta is isolated and isometric tensi...
