A series of
experimental studies on the effects of LICC to the antitumor activity
and cytoim-munity of the tumor loaded animal are reported.The factors
affecting the genesis of LICC andits activity,such as induction time,
concentration of IL-2, cytotoxic cell defferentiation factor(CCDF)and
ratio of effector cell and target cell were screened by orthogonal
test.Thus the opti-mal condition to attain the highest activity of
LICC was obtained...
