大肠杆菌感染后栉孔扇贝血淋巴中7种酶活力的变化

于１９９８年１１月对栉孔扇贝注射大肠杆菌，分别于１，１５，３０ｈ测定了栉孔扇贝血清和血名参与免疫防御的水解，氧化和氧化酶的活力。表明，大肠杆菌激发后，血清实验组的ＡＣＰ活力在１ｈ 于对照组，１５ｈ和３０ｈ时极显著地高于对照组

ACTIVITY CHANGE OF SEVEN ENZYMES IN HAEMOLYMPH IN SCALLOP Chlamys farreri AFTER CHALLENGE WITH Escherichia coli

Seven kinds of hydrolytic, oxidant and antioxidant enzymes participating in the immune defense in the haemolymph of Chlamys farreri were assayed at 1, 15 and 30 h after challenge with Escherichia coli in November, 1998. The results show that the ACP activities of experimental groups in serum were much higher than that of control groups at 1, 15 and 30 h. The ACP activities of experimental groups in haemocytes were much higher than that of control groups only at 15 h. The differences of AKP activities of experimental and control groups in serum and haemocytes were not obvious except the group of serum at 30 h. The differences of lysozyme activities of experimental and control groups in serum and haemocytes were not notable except the group of haemocytes at 15 h. The PO activities of experimental groups in serum were much higher than that of control groups at l, 15 and 30 h. There were no activities of PO in haemocytes. The differences of MPO activities of experimental and control groups in serum were not notable, but the differences in haemocytes were very significant. The differences of SOD activities in serum were not notable, but the differences in haemocytes at 15 and 30 h were very notable. The CAT activities of experimental groups in serum or in haemocytes were much higher than that of control groups at 1 h or at 1 and 15 h.
