Abstract: BACKGROUND/AIM: Laminarin, mainly found in the fronds of Laminaria, has antimicrobial characteristics and induces immune responses. However, there are no available information to show the laminarin effect on glutamic oxaloacetic transaminase (GOT) and glutamic pyruvic transaminase (GPT) levels in mice with leukemia in vivo. MATERIALS AND METHODS: O, respectively, by oral gavage every 2 days for 14 days (total of seven times). All mice were weighed during the treatment. After treatment, mice were sacrificed, blood was collected for determination of cell markers, liver and spleen samples were weighed, and spleens were used for phagocytosis and natural killer (NK) cell activity and cell proliferation using flow cytometric assay. RESULTS: Laminarin did not affect animal appearances, but increased the body weight at all doses. It reduced the weight of liver at 2.5 and 5 mg/ml and of spleen at 5 mg/ml. Laminarin increased CD3 (2.5 mg/ml) and CD19 (1 and 5 mg/ml) cell populations but reduced CD11b (5 mg/ml) cell populations, however, these did not affect Mac-3 marker level. Laminarin at 1 mg/ml increased phagocytosis by macrophages from peripheral blood mononuclear cell, but did not affect those from the peritoneal cavity. Laminarin increased NK cell cytotoxic activity at all doses and at a target ratio of 25:1 and 50:1. Laminarin did not affect B-cell proliferation, but at 5 mg/ml significantly reduced T-cell proliferation. Laminarin restored glutamate oxaloacetate transaminase (2.5 and 5 mg/ml) and glutamate pyruvate transaminase (2.5 mg/ml) levels. Based on these results, we suggest that laminarin can promote immune responses and protect against liver injury.
