    "abstract": "The quantum hadrodynamics are studied by using non-perturbative\nrenormalization group equations. Approximate discrete gamma_5-symmetry is\nstudied. It is shown that the contributions of one-loop diagrams are important\nfor effective potential. A relation between the local-potential approximation\nand the usual Hartree approximation is discussed. The local-potential\napproximation includes contribution of the Fock term to nucleon self-energy,\ncontribution in the usual random phase approximation to meson self-energy and\nvertex corrections in part as well as the Hartree contribution to the effective\npotential. Approximate discrete gamma_5-symmetry is studied phenomenologically\nin the Hartree approximation. This approximate symmetry may exist in nuclear\nmatter.",
