We present new results of the study of the structure and kinematics of two peculiar galaxies UGC 4385 and UGC 4261 supposed to be the polar-ring galaxies on the basis of their previous photometric and long-slit spectroscopy investigation. New information about structure and kinematics of gaseous components was obtained using modern observing techniques such as integral field (3D) spectroscopy. Detailed analysis of the data confirmed that investigated objects have complicated multicomponent structure. The analysis of the spectral data of some candidates to the polar-ring galaxies (PRG) was held. The observations of galaxies were carried out on the 6-m telescope of the Special Astrophysical Observatory of Russian Academy of Sciences using Interferometer Fabry-Perot (IFP) in emission line Hα. For both galaxies the brightness distribution in the Hα-line and in the continuum near Hα, the velocity and velocity dispersion fields of ionized gas were constructed.
