  The search for pulsar (periodic) emission of five gamma-ray pulsars was
carried out using the summed power spectra and the summed periodograms. No
harmonics corresponding to the known pulsar periods were found. The upper
estimations of the integral flux density of the pulsars J0357+3205 (<0.5 mJy),
J0554+3107 (<0.5 mJy), J1958+2846 (<0.5 mJy), J2021+4026 (<0.4 mJy), and
J2055+2539 (<0.55 mJy) is obtained.
