  We present a construction of new bound entangled states from given bound
entangled states for arbitrary dimensional bipartite systems. One way to
construct bound entangled states is to show that these states are PPT (positive
partial transpose) and violate the range criterion at the same time. By
applying certain operators to given bound entangled states or to one of the
subsystems of the given bound entangled states, we obtain a set of new states
which are both PPT and violate the range criterion. We show that the derived
bound entangled states are not local unitary equivalent to the original bound
entangled states by detail examples.
