  New relations between Bjorken polarized, Bjorken unpolarized and
Gross-Llewellyn Smith sum rules are desribed. These relations are valid in the
region, where both perturbative series and the series in power-suppressed
$1/Q^2$-terms do not yet mahifest the features of asymptotic expansions. The
experimentally based considerations support these relations which may surve as
the guide for possible in future measurements of the Bjorken unpolarized sum
rule at Neutrino Factories.
