  The results of measurements of gamma-N total cross section, obtained by the
method of photoproduction processes registration at the Baksan Underground
Scintillation Telescope, are presented. These data at energies sqrt(s)=40-130
GeV confirm the effect of more rapid photon-hadron cross-section rise as
compared to the hadron-hadron ones. It is shown, the increasing of the additive
quark number in the products of photon hadronization can be one of the causes
responsible for this effect. On the basis of the analysis of experimental data
on both gamma-N and gamma-gamma total cross sections, the status of direct and
indirect cross-section measurements is discussed.
