摘要
Objective： To study the anti-tumor effects of the ferment liquid （FL） and to explore the anti-mutagenic effects induced by cyclophosphamide （CP）. Methods： Anti-tumor effects and Anti-mutagenic effects induced by cyclophosphamide （CP） of the ferment liquid were observed in tumor-bearing mice in vivo. Spleen lymphocytes proliferation of mice was stimulated by ConA and NK cell activity was analyzed by the lactate dehydrogenase （LDH） release assay. Results： FL Ⅰ,FL Ⅱ and FL Ⅲ of 16.7, 33.3 and 66.6 ml/kg inhibited growth of Sarcoma 180 sighificanth by 11.6%, 24.2%, 28.0%, 4.8%, 15.2%, 2.2% and 2.1%, 8.5%, 5.2% respectively. Polychromatic erythrocytes （PCE） at all doses of FL Ⅰ and FL Ⅱ were greatly decreased compared with control group （ P 〈 0.05）, but FL Ⅲ has no inhibition effents（ P 〉 0.05）. Production of IL-2 showed no significant difference between all treatment groups. The NK cell killing activity in all treated mice increased by FL Ⅰ and FL Ⅱ was significantly potentiated compared to controls （ P 〈 0.05）. Lymphocytes proliferation of ICR mice were stimulated by ConA 2.5 ml/L and there were no differences between groups. Conclusion： The present data suggested that three kinds of ferment liquid used as health drink have anfi-mutagenesis, immune enhancement effects and showed certain inhibitory effects on S180 tumor growth in vivo.
