Investigation of sympathetic mechanism of inverse relationship between scalp and leg blood flow with increasing intracranial pressure in the rabbit
Intracranial pressure (ICP) is one of most important factors in determining health and function of cerebroscular system. However the methods of measuring ICP are usually invasive . In an attempt to find a noninvasive method to assess ICP, in previous study web found a reverse relationships between changes in ICP and blood flow in scalp (SBF) and leg skin (LSBF) . In this study the role of sympa...
متن کاملSympathetic stimulation using the cold pressor test increases coronary collateral flow.
BACKGROUND Little is known about the vasomotor function of human coronary collateral vessels. The purpose of this study was to examine collateral flow under a strong sympathetic stimulus (cold pressor test, CPT). METHODS In 30 patients (62 +/- 12 years) with coronary artery disease, two subsequent coronary artery occlusions were performed with random CPT during one of them. Two minutes before...
متن کاملStudies on the Course of Vasomotor Fibers as Measured by Thermic Changes in the Feet after Arterial Ligation and Section of the Spinal Cord at Various Levels.
In a previous paper (7) it was shown that in dogs under amytal anesthesia, ligation of both femoral arteries proximal to the profunda branch caused a decrease in the temperature of the feet which was interpreted as indicating a diminution of blood flow. The temperature of the feet remained at this lower level for several hours following which there was a spontaneous rapid rise indicating the de...
متن کاملThe effects of ATP-dependent potassium channel opener; pinacidil, and blocker; glibenclamide, on the ischemia induced arrhythmia in partial and complete ligation of coronary artery in rats
Objective(s): Electrical inhomogeneity between ischemic and non ischemic myocardium is the basis of arrhythmia which occurs following coronary artery occlusion. The leakage of potassium from the ischemic region to the non ischemic region is very effective in the generation of these arrhythmias. The aim of this study is to research the effect of ATP-dependent potassium (KATP) channel blocker (gl...
متن کاملEFFECTS OF NEURONAL BLOCKADE OF NORADRENALINE REUPTAKE IN AN EXPERlMENTAL MODEL OF HEART FAILURE
We investigated neuronal uptake of noradrenaline (NA) at the level of larger vessels (thoracic aorta and vena cava left renal artery and left renal vein lateral saphenous artery and lateral saphenous vein and finally central ear artery and marginal ear vein) in a model devised to mimic heart failure. The model presented here is the rabbit coronary ligation model in which myocardial infarcti...
