  A simple relation between the effective parameters of chiral Lagrangians in
medium as predicted by BR scaling and Landau Fermi liquid parameters is
derived. This provides a link between an effective theory of QCD at mean-field
level and many-body theory of nuclear matter. It connects in particular the
scaling vector-meson mass probed by dileptons produced in heavy-ion collisions
(e.g., CERES of CERN-SPS) to the scaling nucleon-mass relevant for low-energy
spectroscopic properties, e.g., the nuclear gyromagnetic ratios $\delta g_l$
and the effective axial-vector constant $g_A^\star$.
