The production of antibaryons is calculated in a microscopic transport approach employing multiple-meson fusion reactions according to detailed balance relations with respect to baryonantibaryon annihilation. It is found that the abundancies of antiprotons as observed from peripheral to central collisions of Pb + Pb at the SPS and Au + Au at the AGS can approximately be described on the basis of multiple interactions of 'formed' hadronic states which drive the system to chemical equilibrium by flavor exchange or quark rearrangement reactions.

Recently, a large enhancement of the dilepton yield in nuclear collisions was discovered at the CERN SPS. These data triggered a considerable theoretical effort searching for explanations. In my talk the experimental evidence for the dilepton enhancement and the present status of understanding is re
