Within the relativistic Dirac-Brueckner approach we discuss the properties of highly-energetic nucleons and deltas in dense nuclear matter. The effective NN and N..delta.. interactions are constructed in a fully self-consistent way and reproduce all known properties of nuclear matter. We calculate the nucleon self-energy and the density-dependent effective NN and N..delta.. cross sections in a nuclear medium. Results show a sizable reduction of the ..delta.. (pion) production cross section and important changes in the ..delta.. absorption cross sections.
