background: to assess the endothelial function via noninvasive method, in pregnant women with preeclampsia compared to normotensive pregnant women. materials and methods: brachial artery diameter was measured via ultrasound, in 28 women with preeclampcia in case group and normotensive pregnant women in control group, at rest, after inflation of sphygmomanometer cuff up to 250-300 mmhg, immediat...
while a wide array of pathological changes occur in cerebral arteries following subarachnoid hemorrhage (sah), the most consistent is endothelial damage. since the endothelium normally modulates reflexes that influence vascular tone, any damage to it may represent a significant contributor to cerebral vasospasm following sah. this experimental study investigates the correlation between endothel...
background and objective: cardiovascular disorders continue to constitute major causes of morbidity and mortality in diabetic patients. in this study, the effect of chronic administration of tribulus terrestris (tt) feeding was studied on aortic reactivity of streptozotocin (stz)-diabetic rats and some underlying mechanisms were investigated. materials and methods: male diabetic rats receive...
Objective(s): Angiotensin Ⅱ type 1 receptor blockers (ARBs) represent one of the widely used antihypertensive agents. In addition to anti-hypertension effect, some ARBs also show other molecular effects such as activating peroxisome proliferator-activated receptor-γ and so on. Here we studied the effects of telmisartan on the rat isolated mesenteric artery rings pre-contracted by phenylephrine ...
Cardiovascular disorders continue to constitute major causes of morbidity and mortality in diabetic patients. In this study, the effect of chronic administration of sesame (Sesamum indicum L) seed feeding was studied on aortic reactivity of streptozotocin (STZ)-diabetic rats. Male diabetic rats received sesame seed-mixed food at weight ratios of 3% and 6% for 7 weeks, one week after diabetes in...
purpose: to evaluate the adverse effects of intravitreal injection of sterile chloramphenicol eye drops on corneal endothelial cells of donated corneas. methods: 100 donor corneas were enrolled in the study. one eye of each donor underwent intravitreal injection of sterile chloramphenicol eye drops following vitreous tap and the fellow eyes were served as controls. after corneo-scleral excision...
Impaired endothelium-dependent relaxation of blood vessels is a common feature in diabetes but the exact underlying mechanisms have not yet been clarified. In the present study, endothelium-dependent vasorelaxation of aortic rings were evaluated in vitro in streptozocin-induced diabetic and age-matched control rats. Moreover, NO synthase activity of aortic endothelial cells was asse...
We examined the effect of endothelium and lipid emulsion on vasodilation induced by minoxidil at a toxic dose determined underlying mechanism. The effects endothelial denudation, NW-nitro-L-arginine methyl ester (L-NAME), methylene blue, 1H-[1,2,4]oxadiazolo[4,3-a] quinoxalin-1-one (ODQ), glibenclamide, alone or in combination, minoxidil-induced endothelium-intact rat aorta were examined. Addit...
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...
