  We review the experimental results on strangeness and antibaryon production
in heavy-ion collisions at the AGS and SPS. We argue that the observed
enhancement in kaon production at the AGS is consistent with hadronic
description, while the multistrange baryon and antibaryon results at the SPS
may need physics beyond hadronic nature. We call the need for measurements of
low energy antilambda-proton annihilation cross-section in the modeling of
antilambda to antiproton ratio; large value of this ratio is observed in
central heavy-ion collisions at the AGS and SPS. We speculate the importance of
an excitation function measurement of the ratio.
