The studies on the capacities of immune responses of lymphocytes in peripheral blood and immune organs of Grass Carp (Ctenpharyngoden idellus Cuvier et Valencinnes) to PHA and SPA with incorporation of 〓H-TdR and active reaction of Acid α-Naphthyl Acetate Esterase indicated that there were T and B lymphocytes in peripheral blood of grass carp, but only T lymphocyte and no B lymphocyte in the thymus of grass carp. It was justified that the T lymphocytes in peripheral blood was originated from the thymus, and B lymphocyte could be from the spleen and anterior kidney of grass carp.

运用〓H-TdR掺入法和酸性醋酸萘酯酶活性检测法分别研究了草鱼外周血以及免疫器官中的淋巴细胞对PHA和SPA的免疫应答以及化学标志特征，发现草鱼外周血中存在着类似于哺乳动物的T、B两类不同的淋巴细胞亚群；同时也发现胸腺中只有T淋巴细胞，而无B淋巴细胞，提示了胸腺中淋巴细胞可能是外周血中T细胞的来源，而B淋巴细胞可能来自脾脏或前肾。

After 10 days, 20 days and 30 days for grass carp (Ctenpharyngoden idellus Cuvier et Valencinnes) immunized by being injected Aeromonas hydrophilia, the ANAE (acid α-naphthyl acetate esterase) positive cells ratioes increased, and the same time it was found that the ACP activity increased up too, it showed that the fish bodies were being at immune responding situation and their immnue activities enhanced.

通过对草鱼免疫器官的六种同工酶的分析发现：LDH在血浆、血液细胞、脾脏和胸腺中都表达为5条区带，前肾还额外显示出X酶带，血浆只有3条酶带；ADH除了胸腺为一条带以外，其它的均为3条酶带；MDH和3-GPDH在这些组织中均表达为3条酶带；EST在前肾中为7条酶带，其余的都为6条酶带；POX只在前肾和脾脏中表达为2条酶带。

In addition, the r8 cDNA was also expressed at high level in pBAD/TOPO system and showed esterase activity after enterokinase cleavage followed by purification and renaturation.

此外类凝血酶基因r8在pBAD／TOPO中也得到高效融合表达，表达产物经酶切、纯化和复性，测得精氨酸酯酶活性。
