[ Method] After acute toxicity test on mice, collagen peptide from C. nozakii were given to mice by continuous intragastric administration for 30 d at the doses of 25, 50, 100 mg/kg, and then the phagocytosis of macrophage, delayed type hypersensitivity （DTH） and serum hemolysin level were determined. [ Result] Collagen peptide from C. nozakii was atoxic or low toxic, and the three immune indices of experimental groups were signifi- canUy higher than those of the control group （treated with same volume of normal saline） at 0.05 or 0.01 level. E Conclusion] Collagen peptide from C. nozakii has a certain immunopotentiation.展开更多
