In the present report it is supposed that at the Planckian scales (energies) the Heisenberg Uncertainty Principle (HUP) is replaced by the Generalized Uncertainty Principle (GUP). The quantum-gravitational corrections (qgcs) within the scope of GUP are considered for the primordial black holes (pbhs) in the deSitter Space (very Early Univese) and radiation-dominant epoch. In all cases, the shifts in cosmological parameters generated by these corrections were investigated.
