We present preliminary results of the long term spectral monitoring of two
active galactic nuclei with different broad line shapes: Ark 564 and Arp 102B.
Ark 564 is a bright nearby narrow line Syfert 1 (NLS1) galaxy with relatively
narrow permitted optical emission lines and a high FeII/H${\beta}$ ratio, while
Arp 102B is a nearby broad-line radio galaxy with broad double-peaked Balmer
emission lines. The spectra of Ark 564 were observed during 11-year period
(1999-2009) and the spectra of Arp 102B in the 12-year period (1998-2009), with
SAO 6-m and 1-m telescopes (Russia) and the GHAO 2.1-m telescope (Cananea,
Mexico).
