Immune response of <Emphasis Type="Italic">Pseudosciaena crocea</Emphasis> to the injection of <Emphasis Type="Italic">Vibrio alginolyticus</Emphasis>

For the investigation of anti-infection immune response of Pseudosciaena crocea, 160 healthy fish samples were categorized into infected and control groups. Each individual fish in the infected group was injected intraperitoneally (i.p.) with 0.2 ml bacterial suspension of Vibrio alginolyticus in density of 2×10⁷ CFU/ml, while each individual in the control group was injected i.p. with 0.2 ml sterile saline solution (0.85%). It was observed that the artificial injection of V. alginolyticus significantly increased the number of erythrocytes, leucocytes, lymphocytes in peripheral blood as well as peripheral serum antibacterial activity and antibody titer of large yellow croaker, and significantly reduced the number of peripheral blood granulocytes as compared with those in the control group. No significant difference in acid phosphytase and superoxide dismutase activity of serum was detected between the two groups. It is suggested that non-specific immune factors including leucocytes and anti-bacteria substance in peripheral blood played important role at the initial stage of infection, and specific immune factors such as antibody then played important role in response to anti-infection at the latter stage.

Non-specific immune response of bullfrog Rana catesbeiana to intraperitoneal injection of bacterium Aeromonas hydrophila

Non-specific immune response of bullfrog Rana catesbeiana to pathogenic Aeromonas hydrophila was studied to 60 individuals in two groups.Each bullfrog in bacterium-injected group was injected intraperitoneally(i.p.) with 0.2 ml bacterial suspension at a density of 5.2 × 106 CFU/ml,while each one in control group injected i.p.with 0.2 ml sterile saline solution(0.85%,w/v).Three bullfrogs in both groups were sampled at 0,1,3,7,11,15 and 20 days post-injection(dpi) for the evaluation of non-specific immune parameters.It was observed that intraperitoneal injection of A.hydrophila significantly increased the number of leucocytes and that of NBT-positive cells in peripheral blood.Significant increases in serum bactericidal activity and serum acid phosphatase activity were also observed in the bacterium-injected frogs when compared with those in the control group.However,a significant reduction was detected in vitro in phagocytosis activity of peripheral blood phagocytes.No significant difference in changes in the number of peripheral erythrocytes,serum superoxide dismutase(SOD) activity,and lysozyme activity was detected between the two groups.It is suggested that bullfrogs may produce a series of non-specific immune reactions in response to the A.hydrophila infection.     

认真抓好机井建设进一步完善机井管理

区域概况沧州市地处河北省东部,黑龙港流域游,共辖16个县(市)、两个农场,总面积14051ｋｍ2,耕地1180万亩,总人口640万。是河北水资源最紧缺的地市之一。由于地表水源不足,工农业生产主要依靠地下水。近十年来,全市年均开采地下水96亿ｍ3,深层水平均超采近2亿ｍ3,造成地下水位

浅议沧州地下水压采的途径和对策

针对沧州市水资源开发利用中存在地表水不足,浅层地下水苦咸,深层地下水超采,导致水资源严重匮乏的现状。提出通过外调水、雨洪资源利用、节水工程、调整产业结构、健全管理制度等工程措施和非工程措施来实现工程水资源优化配置、实施综合治理措施,探索地下水压采的途径和对策,促进沧州市水资源可持续利用和经济社会可持续发展。     

实施南水北调 改善农村不安全饮水状况

针对沧州市水资源严重匮乏,由于特殊的地理位置和水文条件,造成土地盐碱、浅层水苦成、深层水含氟量高,致使农村饮水困难等问题,提出实施南水北调是解决沧州农村饮水安全的根本措施,并对南水北调配套工程的农村不安全饮水区进行了供水工程规划。     

沧州市农村饮水安全问题及对策
