The effective running coupling constants in the Walecka model are investigated by introducing renormalization-group equations at finite density, where couplings are divided into two parts: density dependence and momentum dependence. The results are applied to one-loop calculations in nuclear matter. {copyright} {ital 1997} {ital The American Physical Society}
