  We first show that the pions produced at high $p_T$ in heavy-ion collisions
over a wide range of high energies exhibit a scaling behavior when the
distributions are plotted in terms of a scaling variable. We then use the
recombination model to calculate the scaling quark distribution just before
hadronization. From the quark distribution it is then possible to calculate the
proton distribution at high $p_T$, also in the framework of the recombination
model. The resultant $p/\pi$ ratio exceeds one in the intermediate $p_T$ region
where data exist, but the scaling result for the proton distribution is not
reliable unless $p_T$ is high enough to be insensitive to the scale-breaking
mass effects.
