Cromakalim dilates rat cerebral arteries in vitro.
Using an in vitro perfusion method, we examined the effects of cromakalim, a potassium channel opener, on the superior cerebellar arteries of 24 rats. Cromakalim had no effect on contractions induced by 129 mM K+ until a concentration of 10(-5) M was reached. Contractions evoked by 10(-5) M serotonin were attenuated by cromakalim in a concentration-dependent manner (p less than 0.05). The diame...
متن کاملP39: The Neuroprotection Effect of Erythropoietin in Cerebral Ischemia
Cerebral ischemia causes death of millions people all over the world, annually and also suffering more people from neurological deficits and neuromuscular disorders. In our country, 250 to 300 people experience mild to severe stroke, daily. In this study we reviewed 120 original paper selected from PubMED database. Our keywords were erythropoietin, anti-inflammatory, stroke, neuropathy and cere...
متن کاملDisease of Major Cerebral Vessels
In 1927 Egaz Moniz, Professor of Medicine at Lisbon University, presented a Paper to the Neurological Society of Paris, oulining his discovery of cerebral angiography. He had used strontium bromide and then sodium iodide, the injection being niade following a cut-down operation on the artery in the neck. In 1937 he recorded the first case of carotid artery occlusion to be demonstrated radiologi...
متن کاملNitroglycerin dilates coronary collateral vessels during exercise after blockade of endogenous NO production.
In a previous study nitroglycerin failed to dilate coronary collateral vessels during exercise. This study tested the hypothesis that failure of nitroglycerin to increase collateral flow occurred because endogenous nitric oxide (NO) had activated the guanylate cyclase vasodilator pathway so that additional NO from nitroglycerin could have no additional effect. Six dogs were collateralized using...
متن کاملNitric oxide dilates rat retinal blood vessels by cyclooxygenase-dependent mechanisms.
It has been suggested that nitric oxide (NO) stimulates the cyclooxygenase (COX)-dependent mechanisms in the ocular vasculature; however, the importance of the pathway in regulating retinal circulation in vivo remains to be elucidated. Therefore, we investigated the role of COX-dependent mechanisms in NO-induced vasodilation of retinal blood vessels in thiobutabarbital-anesthetized rats with an...
