Influences of hypercholesterolemia on the vessel function of isolated rat thoracic aorta.

The Effect of Flavonoid Naringenin on Contractile Response of Thoracic Aorta Isolated from Diabetic Rats

Background & Aims: Considering increasing incidence of cardiovascular disorders in diabetes mellitus and some evidence on antioxidant and antidiabetic potentials of naringenin, this study was conducted to evaluate the beneficial effects of 6-week administration of naringenin on contractile reactivity of isolated thoracic aorta in diabetic rats. Methods: Male Wistar rats were divided into contro...

The Effects of L-Citrulline Pretreatment on the Isometric Tension of the Isolated Perfused Rat Aorta

Background: The achievement of an effective compound for prevention/treatment of hypertension with fewer complications has been of interest in recent years. OBJECTIVES: This study aimed to examine the effects of L-citrulline pretreatment on the tension of isolated rat aortic tissues precontracted by different vasoconstrictors. METHODS: Sixteen male Wistar rats (300-350g) were randomly divided i...

the effect of taftan pozzolan on the compressive strength of concrete in the environmental conditions of oman sea (chabahar port)

cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...

study of the effects of gleditsia caspica extract in rat isolated thoracic aorta

Heartworm extract induces relaxation of isolated rat thoracic aorta

Isolated rat thoracic aortic strips undergoing noradrenaline-induced contraction were treated with an adult heartworm (HW) crude extract and then examined for isometric changes in tension. HW extract caused relaxation of endothelium-intact strips, but not endothelium-denuded strips. This effect was inhibited by treatment with NG-nitro-L-arginine methyl ester hydrochloride (L-NAME) and could be ...
