  Recent NICMOS observations of the central regions of nearby barred galaxies,
NGC5383, NGC1530 and NGC1667 by Regan, Sheth and Mulchaey (1999), all show, in
the unsharp mask map, a pair of distinct trailing spirals which can be followed
all the way to the center. This result is in apparent conflict with the density
wave theory. In this report, we argue that this difficulty may be removed if we
take the self-gravitation of the disc into consideration, or the IILR does not
exist in these galaxies.
