Recently we have started a project dedicated to investigation of statistical environment properties of galaxies for all morphological types. One of the part of the project is a compilation of sample of isolated early-type disc galaxies with follow-up spectral studies. To date, we have observed at the 6m Russian telescope (SAO RAS) a sample of ~12 galaxies and surprisingly found that 7 of them have a large-scale ionized gas kinematics, and 5 of them have a gas decouplings. We will present these galaxies and discuss properties and origin of peculiar gaseous kinematics.
