Abstract：
We studied the medium effects on ρ meson mass by taking account of the vacuum effects with the effective Lagrangian approach. We show that the ρ meson mass decreases with both temperature and chemical potential. Then we checked the validity of Brown-Rho scaling law in different conditions.
