Twenty BALB/c mice were inoculated with cell suspension of Ehrlich tumor. Ten mice were inoculated in the cushion plant (solid form) and the other 10 in the peritoneum (ascitic form). Animals were euthanized on different times (7 and 14 days). Cytological and histological slides, immunohistochemical (PCNA) analysis and NORs silver impregnation technique were performed. The results showed more proliferation on the 7th day in the ascitic form and on 14th day in the solid form, using both analyses (PCNA and AgNORs). The alterations observed in the Ehrlich tumor s proliferation activity suggested that the growth curve is different between ascitic and solid forms. In the first one, the proliferation peak occurs on the seventh day and in the solid tumor the growth curve was more delayed, showing increased proliferative potential after seven days.
