Appearance of granules in the Purkinje cells of dehydrated toads (Bufo arenarum Hensel)

Summary Seven days of dehydration produce alterations in the Purkinje cells of the toad, Bufo arenarumHensel. Aldehyde-fuchsin-positive granules appear in the cytoplasm of the cells and at the same time modifications take place in cytoplasmatic and nuclear ribonucleoproteins. These modifications consist of an increase in nucleolar volume and appearance of a nuclear cap, polarized towards the granules.This study was aided by a grant of the Consejo Nacional de Investigaciones Cientificas y Técnicas of Argentina.
