Thirteen FRBs (Fast Radio Bursts) with identified host galaxies have been published so far, among them three are repeating and the rest are non-repeating. And the localization of FRBs and identification of the host galaxies still remain a challenging job today. The host galaxy of FRBs plays a very important role in the exploration of the origin of FRBs, and constraining the model of the progenitor. This paper studies the 13 localized FRBs. We find that the DM (Dispersion Measure) contributions from host galaxy fluctuates within certain range (0--240pc$\cdot $cm^-3). In addition, the DM contributions from host galaxy are likely correlated with properties of host galaxy (e.g. SFR (Star Formation Rate), metallicity). The statistical association between SFR (metallicity) and DM contributions from host galaxy is of important significance for study of FRBs adjacent environment.
