BRIEF REVIEWS Flow-Induced Trauma to Blood Cells
THE TECHNOLOGY of implantable vascular prostheses and extracorporeal circulation is now commonplace in modern medicine. The essential function of this technology is the passage and/or processing of blood in some manner, and this inevitably requires intimate and prolonged contact between the blood and various manmade devices, e.g., pumps, valves, tubing, membranes, etc. Some systems, such as the...
متن کاملMECHANISMS OF BLOOD FLOW INCREASE INDUCED BY ELECTRICAL STIMULATION
Previous studies have shown that electrical stimulation (ES) increases blood flow, but the exact mechanisms are not clear. The present study was designed to clarify some of the underlying mechanisms involved in this phenomenon. White adult rabbits Lt.-6 months old were used. Animals were anesthetized by sodium pentobarbital (40 mg/kg, IV) and skin blood flow in the thoracic back was recorde...
متن کاملExercise-induced blood flow in relation to muscle relaxation period
BACKGROUND Dynamic exercise is characterized by relaxation periods between contractions. The relaxation period should be considered as a causal factor for determining the magnitude of blood flow during dynamic exercise. The purpose of this study was to investigate the effect of muscle relaxation periods determined by the response of each subject on the exercise-induced blood flow response. ME...
متن کاملMyocardial blood flow in pacing-induced angina.
Current methods of measuring myocardial blood flow using 133xenon have failed to separate normals from patients with ischemic heart disease at rest. In the present study such a separation was attempted by utilizing pacing-induced tachycardia (PIT) to stress the myocardium. 133Xenon was injected into the left coronary artery to measure blood flow in 27 patients at rest and during pacing-induced ...
