	The D-0-<(D)over bar(0)> mixing is analyzed in a weak gauged U(4)(L) x U(4)(R) chiral lagrangian model where the electroweak interaction is introduced as a gauge theory over the meson degrees of freedom. This model allows a particular realization of the G.I.M. mechanism and then could be useful in the study of processes where G.I.M. suppression is effective. As a test of the model we have also analyzed the K-0-<(K)over bar(0)> mixing. We find am, in good agreement with the experimental result and we show that the D-0-<(D)over bar(0)> mixing is very much suppressed in agreement with previous estimates in the Heavy Quark expansion framework.
