The effects of two polysaccharides, AT-HW and AT-AL obtained from the fruiting bodies of Armillariella tabescens on murine sarcoma 180 tumor and peritoneal macrophages were examined at intraperitoneal administration. AT-HW from the hot-water extract and AT-AL from the alkaline extract significantly inhibited the tumor, and the results of different administration schedule and phagocytic system blockade suggested that the mechanism of AT-AL differed from that of AT-HW and branched (1→3)-β-D-glucans. AT-HW and AT-AL showed reticuloendothelial system-potentiating activity, increased the number of peritoneal exudate cells, activated on macrophages (acid phosphatase activity, glucose consumption, superoxide anion production), and enhanced mitogenic reaction, although AT-HW did not produce superoxide anion in vitro.
