Prenatal diagnosis of 21-hydroxylase deficiency by rflp analysis of the 21-hydroxylase,complement C4, and HLA class II genes

In 19 pregnancies at risk for 21-hydroxylase deficiency (21OHD) in 18 families with at lea one affected child, prenatal diagnosis was performed by RFLP analysis using the enzymi Taq I and EcoRI and the DNA probes specific for the 21 OH genes, the closely linke complement C4 genes and the highly polymorphic HLA class II genes DRB, DQB, and DPI For fetal DNA analysis either chorionic villi or cultivated amniotic cells were used. In all 1 cases, a clear prenatal diagnosis was possible either with the 21OH probe alone or in mo cases, by combining the results of the different closely linked loci.

回灌法处理城市垃圾填埋场渗沥液

在调研了国内外文献和模拟试验的基础上,阐述了用回灌法处理城市垃圾填埋场渗沥液的依据、工艺流程和技术参数,提出了应注意的问题。     

促进经济与环境协调发展的基本战略

从与国际先进大城市在环境与经济协调发展方面的比较中，分析上海目前的环境与经济协调发展的状况和面临的主要环境问题。根据上海的城市发展战略的目标和要求，提出了要遵循生态发展规律，以保持城市水资源和改善大气环境质量为重点，优先发展城市基础设施和环境建设，加快能源结构的改善和产业结构的调整，在发展经济的同时不断增加城市生存环境建设投入，以实现已确定的跨世纪的环境保护总目标，促进环境与经济的协调发展的７方面     

湖泊富营养化的形成机理与防治对策

分析了湖泊富营养化的形成机理,并从湖泊治理人才队伍的组建、控制目标的设定、外源性营养物质的控制、内源性营养物质的控制、湖泊生物-生态修复、管理等10个方面探讨了富营养化湖泊的防治对策,指出防治湖泊富营养化是一项复杂的系统工程,必须从控制污染源出发,重点开展生物-生态修复、完善管理对策,有计划分层次地逐步实施.     

两种共生模式之比较

在对两种共生模式—生态工业园和绿色供应链作了基本解释和案例分析后，比较了这两种模式的共性和异性，得出了它们在生态工业体系建设中具有统一性和互补性的结论，对建设城市生态工业体系提出了看法。     

Prenatal diagnosis of endocardial fibroelastosis

In a case of fetal heart failure caused by endocardial fibroelastosis, prenatal echocardiography clearly demonstrated; a thickened endocardium. We therefore suggest that an abnormal endocardium may be detected in utero by ultrasound, thus representing an important clue in the differential diagnosis of fetal nonimmune hydrops and in the evaluation of pregnancies at risk for endocardial fibroelastosis.     

铬在土壤-地下水系统中的污染研究

根据铬在土壤-地下水环境中的化学特性,通过实验,研究了两种价态的铬[Cr(Ⅲ),Cr(Ⅵ)]在水、土中的污染过程,并着重分析了Cr(Ⅵ)在水土体系中所产生的物理化学作用及其在土中的稳定性。结合铬污染实例,阐明了铬在水-土体系中污染的条件和迁移过程。     

Prenatal diagnosis for dystrophia myotonica using the polymerase chain reaction

The polymerase chain reaction has been used to detect an abundant class of short repeat DNA families of the form (dC-dA)n.(dG-dT)n, known as microsatellites. These units are found throughout the human genome and have been characterized for several loci including APOC2 on chromosome 19ql2-ql3.2. The locus APOC2 is linked to the gene for dystrophia myotonica and a microsatellite within this locus was used to derive polymorphisms in a family to predict the inheritance of the disease. Chorionic villus sampling (CVS) was performed at 151/2 weeks' gestation. Following DNA extraction from the CVS material and parental blood samples, microsatellite analysis was carried out by the polymerase chain reaction.
