On the basis of the Second Byurakan Survey (SBS) we have produced the largest and most homogeneous new complete samples of faint Markarian Galaxies and bright QSOs. The volume of reliable investigation of UVX galaxies reaches to ˜ 200 – 250Mpc,– ten times deeper than the FBS.

New reliable data for the surface density of bright QSOs in mag. range 16.05 < B < 17.45 and redshift 0.3 < z < 2.2 are presented. The complete sample of bright(B < 17m5) SBS QSOs contains 93 QSOs in these ranges. The new data allow us to assume that bright QSOs fast evolution might be perhaps the result of a selection effect.
