ABSTRACT

Codnopsispilosula polysaccharides (CPP) , which administered intra-peritoneally 200mg/kg?d-1 for 5 d or 8 d in mice, enhanced thephagocytic activity of peritoneal macrophages on chiken RBC, the erythrocyte (E)rosette formation of thymus T lymphocyte and the clearance rate of charcoal particles in normal mice and antagonized the inhibition of E rosette formation and of peritoneal phagocytic activity caused by cyclophosphamide ( CY ) or hydrocortisone ( HCT ) . It inhibited the delayed type hypersensitivity ( DT H ) induced by DNCB and enhanced DT H induced by dexamethasons ( DMS ) . It has regulatory important signification in resisting decrepitude.
