  The gravitational interaction is discussed within the framework of gauge
gravitational theory in the Riemann-Cartan space-time. In the case of spatially
homogeneous isotopic gravitating systems the gravitational repulsion at extreme
conditions near limiting energy density and the transition from gravitational
repulsion to attraction in dependence on energy density is studied. The
conversion to Friedman regime and the transition to gravitational repulsion at
very small energy densities is analyzed.
