for the two tumor cell lines tested by ,"–&"% rate. On the
other hand, their e+ects on normal cells ($T$ and CHO)
showed that these extracts had no cytotoxicity for these
cells (Table !). Furthermore, they showed an increase in
proliferation on $T$ cells (.broblast cells). A signi.cant
increase was observed in the proliferation especially at !,
or ,( h (approximately $"–,"% proliferation rate) (Table !).
However, this e+ect was not observed for CHOcells (Figure $
and Table !). For CHO, these extracts did not modify the
proliferation rate, even when the extract concentration or
time was changed.
