Abstract
The protein-bound polysaccharide preparation, PS-K, was found to possess an antitumor effect against 3-methylcholanthrene-induced fibrosarcoma in mice which was shown to have a tumor-specific transplantation antigen. This antitumor effect seemed to be exerted through a host-mediated tumor immunity.
