Statistical research of galaxies with UV-excess has been carried out. Sample of 702 Kazarian's galaxies (KG) is used. More than 36 % KG have been identified with infra-red sources at wavelengths 12, 25, 60 and 100 microns. The calculation of FIR luminosities has shown that 4 % of KG is luminous IR galaxies with LFIR 10^11Lsun. More than 32 % KG have been identified with radio sources at frequency 1.4 GHz. Definition of radio luminosities has shown, that in the KG sample there is a radio-loud (LR; 10^25 W•Hz-1) BL Lac type object Kaz 273 with known radial velocity. Tight correlation (r = 0.93) between FIR and radio luminosities for galaxies with UV- excess is received. The investigation of connection FIR and radio luminosities for galaxies of different spectral classes has shown that the coefficient of correlation is higher (r = 0.99), and the inclination of dependence is steeper (a = 1.18) for Seyfert type galaxies. From calculations of logarithm of the ratio FIR and radio flux densities it is established, that in the sample there are 4 KG with radio excess, while galaxies with IR-excess are absent.
