The importance of chorionic villus sampling after first trimester diagnosis of cystic hygroma

The prenatal diagnosis of The Turner Syndrome is described at a menstrual age of 12 weeks. Detection of cystic hygroma was followed by vaginal chorionic villous sampling (CVS) which revealed a 45,X karyotype. Early documentation of fetal karyotype in the presence of a cystic hygroma is essential for accurate diagnosis and genetic counselling.     

絮凝法处理纸浆漂白废水的研究

研究了无机絮凝剂ＰＡＣ，ＰＳＡ，ＰＥＳ，ＭｇＣｌ２，ＣａＯ及其与有机高分子絮凝剂ＣＧＡ复全使用对两种不同工艺漂白废水的混凝处理特性，结果表明，水质１ＣＯＤｃｒ，ＡＯＸ去除率分别为６３．２％，４５．３％，水质２ＣＯＤｃｒ，ＡＯＸ去除率达７３．１￥％，５３．４％。化钙与碳酸钠具有相同的降解ＡＯＸ能力，硫离子在中性ｐＨ条件下可显著提高ＡＯＸ的去除率。     

烧结砖生产中氟的逸出及钙基废渣固氟特性研究

砖坯烧制过程中，氟逸出的初始温度约为600℃，大部分氟在约800℃至砖坯发生明显烧结的温度内逸出，以CaO含量高的粘土原料制砖，氟逸出量相对较少。在此基础上，提出在制砖原料中添加适量钙基废渣抑制氟的逸出，并进行了详细的实验室和工业性试验；结果表明，在适宜添加量下，存氟率由约25％增至70％以下，且不影响砖制品质量。     

Der Einfluß von Verbraucher und Handel auf die Qualität landwirtschaftlicher Produkte und Lebensmittel

The modern consumer is very much interested in healthy food. The reason is that a special group of consumers is focusing more and more attention on health and nutrition problems. Further, there is increased emphasis on education in food science at universities as well as polytechnics. For some years worldwide dietary goals are published with the intention to reduce nutrition-based sickness. For the first time in our nutrition report 1988, clear proposals for optimal nutrition were formulated.     

Limb reduction and chorion villus sampling

Upper limb reduction was diagnosed by ultrasound scan at 17 weeks after chorion villus sampling at 9 weeks' gestation. Pregnancy was terminated and necropsy confirmed limb reduction in an otherwise normal fetus. The relationship of limb reduction to amniotic band syndrome is discussed.
