  We study the evolution of the physical parameter values defined at the
sub-planckian energies to values at low energies. The Wilson action is the
basis of the research. The presence of the compact extra dimensions has two
consequences. The positive point is that the integration over extra dimensions
is a promising way to substantially reduce the parameters to be comparable with
the observational values. On the other hand, the discreteness of the energy
levels of compact extra dimensions complicates the analysis. This difficulty
can be overcome with the truncated Green functions.
