皱纹盘鲍食道的结构与功能

以组织学，组织化学，扫描电镜和透射电镜观察及酶活性测定等方法研究了皱纹盘鲍的食道，食道可分为前，中后，三段，中段又可分为食物通道和食道侧囊，食道粘膜上皮由纤毛柱状细胞，粘液细胞，闰状腺细胞，微绒毛细胞和分泌细胞组成，纤毛柱状细胞参与运输食物和分泌物，并呈现吸收细胞的结构特征；粘液细胞分泌中性和酸性粘多糖；颗粒状腺细胞内充盈分泌颗粒；微绒毛细胞呈现吸收细胞的特征；分泌细胞具有强的蛋白酶等酶活性，能以楔浆分泌形式分泌消化酶，该细胞还具有吸收和细胞内消化作用。食道中段还呈现3种植物多糖酶活性。     

应用双抗夹心ELISA法检测皱纹盘鲍致病病原—创伤弧菌的研究

以皱纹盘鲍脓足病致病病原－ － 创伤弧菌为抗原,制备兔抗血清,抗体纯化后以辣根过氧化物酶标记,建立检测创伤弧菌的双抗夹心ＥＬＩＳＡ 检测法。结果表明,双抗夹心ＥＬＩＳＡ 法有较高的灵敏度,可检出含菌１０４ 个／ｍｌ 的菌悬液。与创伤弧菌对照菌株有明显的阳性反应不与副溶血弧菌、溶藻胶弧菌、河流弧菌等８ 株对照菌株产生影响检测结果的交叉反应。应用该法检测３０ 份病鲍样品,阳性检出率为６６ ．７ ％ 。     

Physiological metabolism of Haliotis discus hannai Ino under different light qualities and cycles

The goal of this experiment was to examine the effects of different light qualities (red, white, blue) and cycles (12L:12D, 8L:16D, 4L:20D, 0L:24D, 16L:8D) on the survival, growth, metabolism and antioxidant defence system of Haliotis discus hannai Ino. Under red and white light at 4L:20D, the body weight‐specific growth rate of abalones was significantly higher than that of the 0L:24D group (P < 0.05). At 16L:8D, succinate dehydrogenase activity decreased and lactate dehydrogenase and alanine aminotransferase activity and the lactic acid content significantly rose (P < 0.05) in the red and white light groups. Under blue light, reactive oxygen species and malondialdehyde content for each light cycle were significantly higher than those of the red and white groups (P < 0.05). Under blue, white and red light, total antioxidant capacity (T‐AOC), superoxide dismutase (SOD) activity, glutathione peroxidase (GP_X) activity and reduced glutathione (GSH) content gradually rose with increased duration of light exposure. Under red light, significant differences in these parameters were detected between the 4L:20D and 16L:8D groups (P < 0.05). Under blue and white light at 16L:8D, values of T‐AOC, SOD, GP_X activity and GSH content were significantly lower than those of the 12L:12D group (P < 0.05). Overall, these results indicate that red light at light cycles of 4L:20D and 8L:16D is optimal for the culture and production of H. discus hannai, as these conditions promoted food intake, growth and health maintenance as well as normal physiological metabolism of the organism.

皱纹盘鲍幼鲍溃烂病病原菌的研究

从患有溃烂病的皱纹盘鲍幼鲍体上，分离到一种致病性细菌。经人工感染试验，证实该菌为皱纹盘鲍幼鲍溃烂病的病原菌。显微镜观察该细菌为革兰氏阴性，极生１～３根鞭毛，能运动的杆菌，大小为０．７～０．８×２．３～２．８ｕｍ。经细菌分类试验鉴定，该菌生长最适温度为２０～３０℃，最适ｐＨ值５．５～８．５。该菌在培养基Ｂ上产生蓝色的荧光素。能利用葡萄糖产酸不产气，果糖、Ｄ－半乳糖、甘露糖、木糖、阿拉伯糖、海藻糖发酵反应阳性，不能发酵乳糖、麦芽糖、鼠李糖、蔗糖，可分解山梨醇、肌醇、肌苷。过氧化氢酶、脲酶、氧化酶、及明胶液化反应阳性；能利用柠檬酸，不还原亚硝酸盐，不产生吲哚和硫化氢，ＭＲ和Ｖ．Ｐ．试验阴性。初步鉴定该病原菌为荧光假单胞杆菌。还进行了病原菌药敏试验，该菌对卡那霉素、呋喃唑酮、恶喹酸敏感，这些药物可作为防治该病的首选药。
