    Abstract:
    The effects of horse anti-human alpha-fetoprotein (AFP) immunoglobulin (IgG) on growth, serum AFP concentration and histopathology of human endodermal sinus tumor serially xeno-transplanted in nude mice were examined. Anti-AFP IgG given in amounts sufficient to neutralize the serum AFP secreted by the tumor moderately reduced tumor size and significantly decreased the serum AFP levels of treated nude mice. On histopathologic examination, spindle shaped tumor cells of reticular pattern often fell into the state of necrosis. But little change was observed on the cells consisting of both solid patterns and Schiller-Duval bodies. With a growth rate of re-transplanted tissues respectively, which were obtained from both antibody administrated and control tumors, no disparity was found between two groups. Indeed this result is preliminary report, but inhibitory effects of anti-AFP IgG against tumor growth and AFP producing ability of endodermal sinus tumor xeno-transplanted in nude mouse is hopeful to apply these data on clinical cancer immunochemotherapy.
