We generalize for the case of arbitrary hydrodynamical matter thequasi-isotropic solution of Einstein equations near cosmological singularity,found by Lifshitz and Khalatnikov in 1960 for the case of radiation-dominateduniverse. It is shown that this solution always exists, but dependence of termsin the quasi-isotropic expansion acquires a more complicated form.Comment: 7 pages, The collective of authors is enlarged and some comments and  references are adde
