The role of spin-orbit interaction, arises from the Dzyaloshinski-Moriyaanisotropic antisymmetric interaction, on the entanglement transfer via anantiferromagnetic XXZ Heisenberg chain is investigated. From symmetrical pointof view, the XXZ Hamiltonian with Dzyaloshinski-Moriya interaction can bereplaced by a modified XXZ Hamiltonian which is defined by a new exchangecoupling constant and rotated Pauli operators. The modified coupling constantand the angle of rotations are depend on the strength of Dzyaloshinski-Moriyainteraction. In this paper we study the dynamical behavior of the entanglementpropagation through a system which is consist of a pair of maximally entangledspins coupled to one end of the chain. The calculations are performed for theground state and the thermal state of the chain, separately. In both cases thepresence of this anisotropic interaction make our channel more efficient, suchthat the speed of transmission and the amount of the entanglement are improvedas this interaction is switched on. We show that for large values of thestrength of this interaction a large family of XXZ chains becomes efficientquantum channels, for whole values of an isotropy parameter in the region $-2\leq \Delta \leq 2$.
