  The amplitudes of hadron-hadron forward elastic scattering at high energy a
re investigated on the basis of analiticity and crossing-symmetry which is
valid in QCD. The universal uniformizing variable for them is proposed and the
formulae for crossing-even and crossing-odd amplitudes are derived. The same
parameters in these formulae determine the real and imaginary (total cross
sections) parts of the amplitudes. The analysis of the parameters determined
from experimental data clearly points to the quark-gluon stracture of hadrons.
The total cross sections for hyperon-proton scattering are predicted. They are
consistent with experimental data and, in particular, with the new
SELEX-collaboration measurement $\sigma_{tot}(\Sigma^{-} p)$.
