We examined the effects of pretreatment of monkey kidney normal cells (CV-1
) and human cervical tumor cells (HeLa) with membrane fusible erythrocyte g
hosts (MFEG) encapsulating superoxide dismutase (SOD-MFEG) on adriamycin (A
DM) cytotoxicity. The decrease in CV-1 cells with ADM was inhibited markedl
y, and the initiation of decrease in HeLa cells was delayed for 2 days by t
he pretreatment with SOD-MFEG, indicating that the delivered SOD held the a
ctivity in the cells. (C) 2000 Elsevier Science B.V. All rights reserved.
