  In the process of work it has been found that space-time quantum fluctuations
are naturally described in terms of the deformation parameter introduced on
going from the well-known quantum mechanics to that at Planck scales and put
forward in the previous works of the author. As shown, with the use of quite
natural assumptions, these fluctuations must be allowed for in Einstein
Equations to lead to the dependence of the latter on the above-mentioned
parameter, that is insignificant and may be ignored at low energies but is of
particular importance at high energies. Besides, some inferences form the
obtained results are maid.
