  We present analytical results on the two-loop anomalous dimensions of
currents for baryons, containing two heavy quarks $J = [Q^{iT}C\Gamma\tau
Q^j]\Gamma' q^k\epsilon_{ijk}$ with arbitrary Dirac matrices $\Gamma$ and
$\Gamma'$ in the framework of NRQCD in the leading order over both the relative
velocity of heavy quarks and the inverse heavy quark mass. It is shown, that in
this approximation the anomalous dimensions do not depend on the Dirac
structure of the current under consideration.
