We have studied the central parts of seven early-type galaxies -- the membersof the X-ray-bright galaxy group NGC 80 -- by means of integral-fieldspectroscopy at the Russian 6m telescope. We searched for signatures ofsynchronous evolution of the group galaxies. The following results have beenobtained. Five galaxies have revealed old stellar populations in the bulges,with the SSP-equivalent ages from 10 to 15 Gyr. A moderate-luminous S0 galaxyIC 1548 demonstrates consequences of recent star formation burst: theSSP-equivalent age of the bulge is 3 Gyr, that of the nucleus -- 1.5 Gyr. It isalso in this galaxy that we have found a circumnuclear polar gaseous disk whichchanges smoothly to counterrotating one at radii larger than 3 arcsec(1 kpc).Probably, IC 1548 had suffered an interaction with external gas accretion whichmight also provoke the central star formation burst. In the giant E0 galaxy NGC83 which is projected close to the group center but has a line-of-sightvelocity redshifted by 600 km/s with respect to the group systemic velocity, wehave observed a compact massive stellar-gaseous disk with the radius of some 2kpc demonstrating current star formation. Consequently, NGC 83, just as IC1548, has the young stellar population in the center. We speculate that a smallsubgroup leaded by NGC 83 is in process of infalling into the old massive grouparound NGC 80.
