  In this paper, we report our preliminary results on enhanced star formation
activity in Seyfert 2 galaxies. By re-analysing the Tully-Fisher relation for
Whittle(1992)'s sample and for a Seyfert 2s' sample selecting from Veron-Cetty
& Veron (1996), we find that (1) almost all Seyfert 2 galaxies with
circumnuclear star formation have a ratio of far infrared (FIR) to blue
luminosities ($L_{FIR}/L_{B}$) to be larger than 1/3; (2) for Seyfert 2
galaxies with $L_{FIR}/L_{B} < 1/3$, the Tully-Fisher relation is similar to
that of the normal spiral galaxies; while for those with $\rm L_{FIR}/L_{B}
\geq 1/3 $, they are significantly different from the normal ones, which
confirms Whittle's suggestion of enhanced star formation activities in the
circumnuclear regions of these Seyfert 2 galaxies.
