Giant radio sources are the largest single objects in the Universe. Their projected linear sizes are greater than 0.7 Mpc. The largest known ``giant'' has a size of about 4.7 Mpc (which is comparable to those of cluster of galaxies or larger). Up to now, there are no unambiguous answers what are the reasons of the extremely large size of a small fraction of radio galaxies. It might be possible that giant radio sources have extremely powerful active galactic nuclei. In addition, they might evolve in low-density cluster environment and/or their nuclear activity could be of recurrent character. One can expect, that the behavior of the central active galactic nucleus should influence on intensities of the optical spectral lines of its host galaxy. In this paper we study correlations between ratios of the lines intensity, the total radio luminosity and the projected linear size of ''giants``. It seems, that the dominant ionization mechanism in ''giant`` host galaxies is photo-ionization by the central active galactic nucleus.
