[en] New observational data on the spectra of thirteen planetary nebulae and their nuclei are given. New nuclei of the WOLF-RAYET type containing both nitrogen and carbon have been found. Previously adopted WOLF-RAYET designations have been modified. Nuclei of planetary nebulae, despite their occasional resemblance to WOLF-RAYET stars, should not be associated with the latter.
