Popis: Hericium erinaceus, an edible and medicinal mushroom belonging to the Basidiomyco ta family, has been used for curing gastric ulcers and stomach cancers in human beings and is also known to have good inhibitory effects on sarcoma 180 and Ehrlich carcinoma in mice. Neutral saline soluble (0.9% NaCl), hot water soluble and methanol soluble substances (hereinafter referred to as Fr. NaCl, Fr. HW and Fr. MeOH, respectively) were extracted from the fruiting body of the mushroom. In in vitro cytotoxicity tests, crude polysaccharides were not cytotoxic against cell lines such as Sarcoma 180, HepG2, HT-29 and NIH3T3 at concentrations of 10~2,000 μg/ml. Intraperitoneal injection with crude polysaccharides exhibited a life prolongation effect of 29.1~54.1% in mice previously inoculated with Sarcoma 180. Fr. Na increased the numbers of spleen cells by 2.9 fold at a concentration of 50 μg/ml compared with the control. Fr. Na improved the immuno-potentiating activity of B lymphocytes by increasing alkaline phosphatase activity by 5.5 fold compared with the control at a concentration of 200 μg/ml. Fr. NaCl increased the numbers of peritoneal exudate cells and circulating leukocytes by 4 and 2.3 folds at a concentration of 50 mg/kg, respectively. Therefore, the crude polysaccharides extracted from the fruiting body of H. erinaceus could improve antitumor activities in mice.
