Abstract: AIM: To investigate the effect of peritoneal macrophages in mice on tumoricidal activity against colon cancer HCT116, following intraperitoneal injection of Mistletoe Lectins. METHODS: 16 mice were divided into control group and intraperitoneal chemotherapy group. The number of peritoneal macrophages was counted by trypan blue exclusion. The amount of TNF-α and NO expressed by peritoneal macrophages was measured by ELISA and Griess, respectively. The cytotoxity of peritoneal macrophages supernatant against HCT116 was evaluated by MTT assay. RESULTS: It was found that the amount of peritoneal macrophages was increased, the expressions of TNF-α and NO were increased and the cytotoxicity against HCT116 in vitro was increased after intraperitoneal injection of Mistletoe Lectins. CONCLUSION: Intraperitoneal injection of Mistletoe Lectins can activate the peritoneal macrophages in mice and enhance the cytotoxity of the supernatant against HCT116 in vitro.
