STUDIES ON IMMUNODIAGNOSIS OF HEPATOPANCREATICPARVO-LIKE VIRUS DISEASES OF PENAEUS ORIENTALISII. RAPID EARLY DIAGNOSIS     

孙修勤  王文兴  邵济钧  张进兴  卢颖  薛清刚  宋庆云 《中国海洋湖沼学报》1993,(3)

This paper describes a rapid procedure for diagnosis of penaeid viral disease using the immune serological method. The SPA (Staphylococcal Protein A) coagglutination test in early diagnosis of penaeid viral disease has yielded satisfactory results.This is the first time SPA is used in China for diagnoses of viral diseases of marine invertebrates, especially penaeid shrimp.The SPA early diagnostic method is characterized by accuracy, rapidity, simplicity and convenience, low cost, high specificity, strong sensitivity and micro-detectability, and easy dissemination and adaptability in prawn farms.  相似文献

咸潮入侵对长江河口地区地下水质的影响   总被引：1，自引：0，他引：1  

奚建国  邱桢安 《上海国土资源》1991,(1):25-34

长江河口咸潮入侵对上海市自来水源水水质带来不良影响,从而殃及水厂产水质量而不利于生产和市民健康,这在上海市宝山区表现尤为显著。然而,宝山区地下承压含水层水质优良,资源丰富,且水质稳定,不受咸潮入侵影响。经研究,在不产生地面沉降危害等前提条件下,宝山区尚可扩采500万米~3/年优质地下水。  相似文献   

蒙脱石——一种治疗氟骨症的新药材     

李作贞 《陕西地质》1991,(2)

选作药用的蒙脱石。采自陕西省一处探明的粘土矿。矿体呈似层状,透镜状,产于第四系下更新统地层中,层位明显。矿石的矿物成分主要是蒙脱石和石英;化学成分以 SiO_2、Al_2O_3为主;总比表面和阳离子交换容量较大,交换性阳离子以 Ca~(2+)为主,其次是 Mg~(2+)。依照试验确定的活化方法和条件,将蒙脱石试样酸化处理,制成片剂,在氟病现场进行临床疗效观察。临床证明,用蒙脱石治疗氟骨症,效果显著,且无毒副作用。  相似文献   

某公路软弱地基上的高填方路基开裂失效病害处治对策研究     

陈紫云 《地质灾害与环境保护》2016,(1):51-58

以我国西南某高速公路软弱地基上的高填方路堤开裂失效病害实例作为研究对象,以病害现象反复发生反复处治、病害认识不断加深的历程作为基础:先是因为对软弱地基处理方式失当而在路堤填筑过程中产生了侧向滑移病害;后又因为对病害机制认识不准确,导致制定的治理方案处治病害不彻底,使得路堤重新填筑过程中再次产生了侧向滑移病害;然后,再次因为对病害机制的认识还是不到位,并且对治理方案作用机理的理解不透彻,导致了病害进一步加重而致使路堤不得不重新填筑。通过对病害发生、发展过程的再认识和再评估,对病害发生机制进行了较为深入的探究和论述,对未能达到预期的病害处治对策进行了总结和反省,提出了病害防治的应对策略和思路,形成了病害处治方案且经历了实践的验证。  相似文献   

对虾病毒病与化学需氧量相关关系研究   总被引：19，自引：0，他引：19  

马建新  刘爱英  宋爱芹 《海洋科学》2002,26(3):68-71

通过对虾池内主要环境因子与对虾病毒病相关关系的研究,发现虾池内化学需氧量（COD）太高是诱发对虾病毒病暴发流行的主要环境因子之一。利用多级S型净化池可以大幅度消除水体中的COD,有效预防对虾病毒病的暴发流行。  相似文献

刘大磊  董洵  卢毅 《海岸工程》2006,25(2):107-114

近年来,对虾病毒病的爆发,使我国养殖对虾的年产量大幅度下降,造成了巨大的经济损失。就对虾细胞培养研究现状、应用前景和存在的关键问题等进行了综述和讨论。  相似文献   

T-E染色法用于对虾暴发性流行病的现场快速诊断   总被引：13，自引：2，他引：13  

黄倢  杨丛海  于佳  宋晓玲 《海洋科学》1995,19(1):29-34

用Ｔ－Ｅ染色法可对该病进行现场快速诊断。取发病对虾的胃上皮区组织 或鳃组织，用Ｔ－Ｅ染液进行压片染色，可观察到上皮细胞核和结缔组织细胞核的病 毒性病理变化：细胞核质被挤到核的边沿，核内空泡化。发病严重的对虾胞核显著 膨大，核内呈嗜伊红着色。用这一染色法在现场仅需１０ｍｉｎ就可掌握对虾的细胞病 理变化，诊断结果与组织切片的Ｈ－Ｅ染色法一致。  相似文献
