Objective(s): Morphine dependence (MD) potently protects heart against ischemia reperfusion (IR) injury through specific signaling mechanisms, which are different from the pathways involved in acute morphine treatment or classical preconditioning. Since opioid receptor density changes post cerebral ischemia strongly correlated with brain histological damage, in the present study, we tried to el...

BACKGROUND Protection of remote ischemic preconditioning on neurocognitive function caused by bilateral common carotid artery occlusion has been investigated in rats. MATERIAL/METHODS Thirty-six male Sprague-Dawley rats were divided into 3 groups - control group (Group C, n=12), bilateral carotid arteries occlusion group (Group B, n=12) and remote ischemic precondition group (Group P, n=12). ...

1024x768 normal 0 false false false en-us x-none ar-sa background and objective: numerical modeling of biological structures would be very helpful tool to analyze hundreds of human body phenomena and also diseases diagnosis. one physiologic phenomenon is blood circulatory system and heart hemodynamic performance that can be simulated by utilizing lumped method. in this study, we can predict hem...

Nine cases of carotid body tumor chemiodectomas in seven Patients are presented and diagnostic and therapeutic problems discussed Similar to other reports, many cases undergo operative exploration without correct preoper.ativ.e diagnosis or ability of the surgeon to handle such lesions. The most important factor for correct diagndsis is including carotid body in differential diagnosis of latera...

The influence of common carotid occlusion on intraocular pressure was studied in rabbits by perfusion and tonographic techniques. Bilateral common carotid occlusion caused a greater ocular volume change than homolateral occlusion. If homolateral occlusion was followed by contralateral occlusion, there was consistently an additional fall in intraocular pressure. The initial fall in intraocular p...

Effects of Bilateral Carotid Artery Ligation on Brain Lactate and Pyruvate Concentrations in Normotensive and Spontaneously Hypertensive Rats • Brain lactate, pyruvate, and arterial acid-base balance were measured in normotensive rats (NTR) and spontaneously hypertensive rats (SHR) 60 minutes after bilateral carotid artery ligation. Brain lactate and lactate-pyruvate ratios were significantly i...

Coarctation of the aorta secondary to a cervicomediastinal thorotrastoma developed in a 30-year-old man 25 years after carotid arteriography. Other local manifestations of the thorotrastoma included occlusion of the left common carotid artery and partial occlusion of the left vertebral and left subelavian arteries, bilateral recurrent laryngeal nerve paresis, periesophageal adhesions, and multi...
