The results of spectral monitoring of the Seyfert galaxies NGC 4151 (1986 - 96) and 3C 390.3 (1995 - 96) obtained at the 6 m telescope are presented. The behaviour of the broad component profiles of Hβ and continuum is studied. Quasisimultaneous variations of the fluxes in the blue and red wings of Hβ in both galaxies are detected, which is indicative of the absence of considerable radial motions in BLR. The authors confirm the obtained by Veilleux and Zheng (1991) sinusoidal dependence with a period of ≡10 years for the ratios of the observed fluxes of the blue and red wings of Hβ in 3C 390.3 spectra.
