Effects of Fungus Polysaccharide on Immunological Activities of Serum and Lymphocyte of Penaeus chinensis

摘要

Fungus polysaccharide extracted from Cordyceps miliaris was used as immunopotentiator, and was tested the effects on immunological activities of serum and lymphocyte of Penaeus chinensis. After the prawns were injected intraperitoneally by fungus polysaccharose, the phagocytic rate and phagocytic index of lymphocyte, and the immune activities of serum were detected. The results showed as followed: When the prawn had been injected for 48 hours, the phagocytic rate of lymphocyte increased by 11. 4%, the phagocytic index increased by 39. 7% . The hemolytic ability and bacteriolytic ability of serum improved evidently over the control group, and preserved at a high level until 96 hours after injection. Hemagglutinating activity of the serum of P. chinensis enhanced too. The fungus polysaccharide could strengthen the non-specific immune function of P. chinensis.
