    The effects of several ecologic factors on the larval development and survival rate of the sea cucumber Apostichopus japonicus (Selenke) are analysed and summarized on the basis of the data obtained in 1979-1986. The optimal larval density is about 5×105/m3. The optimal number of postlarvae on unit area substratum was 1.0 × 105-4.2×105/m2. The survival rate from larvae to postlarvae was 34-80.8%, but 82.4% survival rate was achieved by feeding the larvae with three species of unicellular algae, Disnaliella euchloin,...

    The effects of several ecologic factors on the larval development and survival rate of the sea cucumber Apostichopus japonicus (Selenke) are analysed and summarized on the basis of the data obtained in 1979-1986. The optimal larval density is about 5×105/m3. The optimal number of postlarvae on unit area substratum was 1.0 × 105-4.2×105/m2. The survival rate from larvae to postlarvae was 34-80.8%, but 82.4% survival rate was achieved by feeding the larvae with three species of unicellular algae, Disnaliella euchloin, Dicrateria zhanjiangensis and Chaetoceros muelleri. The postlarvae adheres to the white PVC plate covered by benthonic diatoms. The shelf-shaped substratum made of PVC can provide larger space for 60-70% of postlarva in the pool to adhere to it. One ppm of dipterex is sufficient to kill harmful cope-pods.

    本文根据1979~1986年间刺参人工育苗试验结果,综合讨论了多年培育刺参幼体中涉及的幼体密度、饲料类别、附着器材质等主要因子对幼体成活率及发育变态为稚参的影响。结果表明:把握好上述因子及参数,可提高幼体的变态率及稚参的单位面积(1m~2,下同)出苗量,确保良好而稳定的育苗效果。

    The principles of the modified Dot-ELISA are to render the antigen dotted Nc paper adherent to the bottom of the shallow wells (10mm x 1.5mm) on a PVC plate and to apply antigens of 4 species of parasite i.e. Schistosoma japonicum, Paragonimus westermani, Clonorchis sinensis and Echinococcus granulosus separately on the same peice of NC paper, which is clearly partitioned into 4 squares by a cross( + ). Hence one serum sample can be screened against 4 antigens concurrently, and reactions with homologus...

    The principles of the modified Dot-ELISA are to render the antigen dotted Nc paper adherent to the bottom of the shallow wells (10mm x 1.5mm) on a PVC plate and to apply antigens of 4 species of parasite i.e. Schistosoma japonicum, Paragonimus westermani, Clonorchis sinensis and Echinococcus granulosus separately on the same peice of NC paper, which is clearly partitioned into 4 squares by a cross( + ). Hence one serum sample can be screened against 4 antigens concurrently, and reactions with homologus and heterologus antigens can be compared simultaneousely. Sixty serum samples, 15 for each parasitosis collected from parasitologically comfirmed patients,were tested by using this modified Dot-ELISA. 33 sera from healthy persons were employed as controls. The results showed that at optimum dilutions, the positive rate for the homologous antigen-antibody reaction reached 93%~100%, while false positive rate being 3%. With heterologous antibodies,cross reactions of 0~20% were observed.The modified Dot-ELISA turned out to be more convenient, labor-saving , easy to perform and could be developed into a diagnostic kit for multiple parasitological mass survey.

    改良的Dot-ELISA法,即将点好抗原的NC膜固着于PVC浅孔软板内进行试验。本文以血吸虫卵抗原、肺吸虫成虫抗原、华枝睾吸虫成虫抗原、细粒棘球蚴囊液抗原等4种抗原膜,用改良的Dot-ELISA法,对血吸虫病、肺吸虫病、华枝睾吸虫病、细粒棘球蚴病患者血清各15例以及正常人血清33份进行试验。结果表明:各种抗原与其对应的血清反应在适宜的比例中阳性率可达93%~100%。假阳性率3%。这种改良的Dot-ELISA法,简便易行,可望发展成为一种适用于现场开展多种寄生虫调查的药盒。
