  This review is devoted to the discussion of hadron properties in the nuclear
medium and its relation to the partial restoration of chiral symmetry. Special
attention is given to disentangle in-medium effects due to conventional
many-body interactions from those due to the change of the chiral condensate.
In particular, we shall discuss medium effects on the Goldstone bosons (pion,
kaon and eta), the vector mesons (rho, omega, phi), and the nucleon. Also, for
each proposed in-medium effect the experimental consequence and results will be
reviewed.
