  The "returning to resonance" mechanism can be used to obtain the simple
procedure of taking RC to DIS cross section into account, in frames of
Drell-Yan picture. Iteration procedure is proposed.
  Kinematic region $y \to 1$ can be described in frames of Drell-Yan picture
using structure function approach. The large RC in the lowest order reflect
Sudakov form factor suppression, which can be taken into account in all orders
of perturbation theory. Basing on explicit calculation in two lowest orders of
perturbation theory we construct the cross section in $y \to 1$ region obeying
renormalization group equations and include the Sudakov-like form factor
suppression.
