title: [Iodized contrast media. I. effector action on serum enzymes].
abstract: In vitro studies were done to examine the effects of contrast media on blood enzymatic activities. The results observed are very significant: in the most simple cases they result in a competitive or mixed-type type inhibition of these enzymes. In systems which involve two substrates and two products a Bi-Bi ping-pong enzymatic mechanism is transformed in Bi-Bi random enzymatic mechanism.
