By using the methods of transmission electron microscopy(TEM) and biochemical extraction-scanning electron microscopy(SEM),it was found that the macronucleus and micronucleus of the ciliated protozoan Euplotes elegans display different characteristics.

To search into the somatic function of the micronucleus of the ciliated protozoan Histriculus similes, all amicromucleates were generated with treatment of cis-dichlorodiammineplatinum(Ⅱ) (cis-platin), a DNA cross linking agent, which has differential effect on the micro- and macronucleus of Histriculus similes.

platin),a DNA cross linking agent,which exert differential ef- fects on the micro-and macronucleus of Histriculus similes For the reason that micronuclei in the G1 phase are more sensitive to cis.

During the dehydrogenation process, its phase transformation period includes nucleation and growth, and steady growth of the new phase with no new crystal nucleus appearing, according to the change of Avrami index.
