Title: Effects of mannuronate polysaccharide on enzymes of Penaeus chinensis related with immune and hemolysis
Abstract: Acid phosphatase (ACP), alkaline phosphatase (ALP) and peroxidase were found in the serum, meat and hepatopancreas extrace of Penaeus chinensis. The activities of ACP and ALP in the hepatopancreas were highest among the serum, meat and hepatopancreas. After Penaeus chinensis were stimulated by injection with 1. 0% polymannuronic acids, the activities of bacteriolysis and hemolysis in the serum increased, meat and the activities of ACP and ALP in the hepatopancreas enhanced obviously. ACP activity increased from 3. 21 (U. l00mL- 1 )of control group to 9.69(U. l00mL-1 ) and ALP activity increased from 4.09(U. l00mL- 1 ) to 13. 2(U' l00mL- 1 ) after 72 hours. However, the activities of these two enzymes in the serum and meat extract extract stable. The activities of POD in serum, and hepatopancreas changed little. So mannuronate polysaccharide could strengthen the immunological competence of Penaeus chinensis, and possessed some developmental value in aquatic culture.
