Abstract: Purpose: To investigate the immunoregulation effect of polysaccharides from sweet potato vines (PSPV). Methods: By using carbon particle clearance test, study the nonspecific immunological function of (PSPV) on normal and immunosuppression mice. By using the hemolysin test, study the specific humoral immunological effect of PSPV on normal mice. Results: The carbon particle clearance index and phagocytic index of normal and immunosuppression mice are increased by giving PSPV to the mice. HPSPV, 800mg/kg dose, has remarkably significant effect on HC50. Conclusions: PSPV has potent enhancement effects on non-specific and specific humoral immunity function of mice.
