  Massive black holes detected in the centers of many nearby galaxies are
linearly correlated with the luminosity of the host bulge, the black hole mass
being about 0.1% of the bulge mass. An even stronger relation exists between
the BH mass (Mbh) and the stellar velocity dispersion in the host bulge. We
show that massive BHs of AGNs (measured by reverberation mapping) and their
bulge luminosity (measured by using a bulge/disk decomposition) follow the same
relations as ordinary (inactive) galaxies, with the exeption of narrow line AGN
which apparently have significantly lower BH/bulge ratios. Narrow line AGNs
seem to be outstanding also in the Mbh-velocity dispersion relation: the few
Seyfert galaxies with measured velocity dispersion seem to indicate that narrow
line Seyfert 1 galaxies have a smaller BH mass/velocity dispersion ratio than
quiescent galaxies and broad line Syferts. Estimating the velocity dispersion
for from the bulge luminosity with the Faber-Jackson relation more than doubles
the sample and supports these results.
