[Experimental studies of the vascular reactions in selected microcirculatory areas as affected by various x-ray contrast media]

After application of various ionic and non-ionic contrast media in the myocardium and intestine of rats, significant changes of flow conditions in the terminal vascular bed were observed with intravital microscopy: Amidotrizoate causes severe disorder in microcirculation distribution (heterogeneous perfusion, functional shunts), while Ioxaglate, Iopromide, Iohexol, Iotrolan cause significantly less microcirculation reactions.
