  The experimental data from the 2m propane bubble chamber have been analyzed
for pC$\to \Lambda(K^0_s)X$ reactions at 10 GeV/c.
  The estimation of experimental inclusive cross sections for $\Lambda$ and
$K^0_s$ production in the p$^{12}C$ collision is equal to $\sigma_{\Lambda}$=
13.3$\pm$1.7 mb and $\sigma_{K^0_s}$= 3.8$\pm$0.6 mb, respectively.
  The measured $\Lambda /\pi^+$ ratio from pC reaction is equal to
(5.3$\pm0.8)*10^{-2}$. The experimental $\Lambda /\pi^+$ ratio in the pC
reaction is approximately two times larger than the
  $\Lambda /\pi^+$ ratio from pp reactions or from simulated pC reactions by
FRITIOF model for the same energy. The $\Lambda /\pi^+$ ratio in interaction
C+C at momentum 10 Gev/c is four times larger than the $\Lambda/\pi^+$ ratio
from p+p reactions at the same energy.
