The influence of coronary collateral flow on the assessment of myocardial perfusion by videodensitometry.

abstract：:The effect of chronic propranolol administration (2 mg.kg-1.d-1 for 14d) and withdrawal on microvascular perfusion was studied in rabbit myocardium. Fluorescein isothiocyanate-dextran was injected into four groups of anaesthetised open chest rabbits. Fluorescent microscopy was used to identify the perfused vessels and...

abstract：BACKGROUND:Nitric oxide (NO) attenuates neutrophil (PMN)-mediated damage, partly by inhibiting superoxide anion (O2-) generation and adherence to the coronary artery endothelium. L-Arginine is the endogenous substrate for production of NO via the NO synthase pathway. This study tested the hypothesis that the endogenous...
