We find that the chemical potential of the $Θ^+$ is shifted in a density-dependent way to one-loop order. We also investigated the effect of the scaled nucleon mass in dense medium on the $Θ^+$ propagator. The results turn out to depend sensitively on the scaled nucleon mass and on the parity of the $Θ^+$.7 pages, 3 figures. Final version published in J. of. Kor. Phys.
