Abstract:
Objective: To study the immune enhancing effect of saponins from American ginseng and its mechanism. Methods: The drug dosage of American ginseng saponin extract and the optimal modeling dose of rapamycin were determined by tolerance test and immunodeficiency model establishment experiments. Zebra fish were divided into control group (0.5% dimethyl sulfoxide), model group (4 μg/mL rapamycin), and three origins American ginseng treatment groups with different concentrations (Shandong, Northeast, Canada, 4 μg/mL rapamycin +10, 25 and 50 μg/mL American ginseng saponin extract) 48 h after fertilization (48 hpf). After a certain period of incubation, the number of neutrophils in the tail of zebrafish, macrophage phagocytosis, and interferon gamma (IFN-γ) content in the body were used as indexes, and the growth rate of neutrophils was calculated to investigate the immune-enhancing effect of American ginseng saponins. Results: When the dosage of American ginseng saponins was higher than 50 μg/mL, the mortality of Zbra-fish increased with the increase of the concentration and the time of administration; Compared with control group, in model group, the number of neutrophils in the tail of zebrafish was decreased significantly (P < 0.01), and the content of IFN-γ in the body was decreased significantly (P < 0.01); Compared with model group, in 10 μg/mL and 25 μg/mL American ginseng treatment group, the number of neutrophils in the tail of zebrafish was increased significantly (P < 0.01), the number of macrophages engulfing ink particles was increased significantly (P < 0.01), the content of IFN-γ in vivo was increased significantly (P < 0.01), and the growth rate of neutrophils was between 19.73% and 96.49%. Conclusion: The American ginseng saponins have a better effect on enhancing immunity.
