兼性生化处理生活污水最佳工况研究

在常温条件下进行兼性生化处理生活污水试验,研究COD去除率与HRT、MLSS、进水有机物浓度和混合液水温的关系。在试验中最佳的水平搭配为MLSS=5500mg/L,进水有机物浓度=180mg/L,HRT=8h和混合液水温=20℃,与回归分析所得出MLSS=5881mg/L,进水有机物浓度=192.7mg/L,HRT=8.9063h和混合液水温=21.3790℃的最佳工艺条件相吻合。最后通过等高线分析得出常温下生活污水兼性生化的适宜范围。     

悬浮颗粒物对黄河铜的生物有效性影响的研究

利用t检验分析了悬浮颗粒物对黄河水体中铜的生物有效性的影响.结果表明,虽然过滤后水样的EC50比未过滤水样的EC50高,但是过滤前后24h-EC50和48h-EC50在统计学上没有显著差异;而过滤前后72h-EC50和96h-EC50存在显著差异.通过分析,认为造成这种现象的原因有两个:(1)未过滤的水样泥沙含量阻碍了藻类的光合作用;(2)试验过程中水样的理化性质发生改变,导致颗粒物中吸附的铜再次发生了解吸现象。     

青岛地区大气气溶胶海洋因子贡献研究

本文对青岛地区大气气溶胶海洋因子的贡献进行了分析研究，得出以下结构：（１）复季受海洋影响要比冬季明显得多；（２）就质量浓度而言，ＩＰ（ｉｎｈａｌａｂｌｅ ｐａｒｔｉｃｌｅ）中的海盐源要高于ＴＳＰ（ｔｏｔａｌ ｓｕｓｐｅｎｄｅｄ ｐａｒｔｉｃｕｌａｔｅｓ）；（３）海洋影响的程度和离海边的距离有关。离海逾远，受海洋影响就逾小；离海连逾近，受其影响就逾大；（４）ＩＰ冬季海盐源为２％－４％，夏季为１０％－     

Verification of carrier status for Becker muscular dystrophy from analysis of a blighted ovum

The polymerase chain reaction (PCR) was used on material from a blighted ovum to confirm indirectly the carrier status of a woman with a family history of Becker muscular dystrophy. Conventional testing including creatine kinase levels, muscle biopsy, and EMG had been inconclusive, and on the basis of one elevated creatine kinase level, the woman had been designated a possible carrier. Ultrasound examination at 10 weeks of pregnancy indicated a blighted ovum, from which DNA was subsequently extracted and subjected to PCR testing for determination of sex and genotypic status with respect to the known familial deletion of the dystrophin gene. The blighted ovum was found to have a Y chromosome and also to be deleted for at least exon 6 of the dystrophin gene, indirectly indicating that the mother most likely carried the family mutation for Becker muscular dystrophy.     

丁基锡化合物在水体悬浮颗粒物上的吸附行为研究

将海河河口表层底泥制成悬浮颗粒物（ＳＰＭ），采用批量平衡法首次研究了模拟河口条件下三丁基锡（ＴＢＴ）和二丁基锡（ＤＢＴ）在该ＳＰＭ上的吸附行为．结果表明，ＴＢＴ和ＤＢＴ均能在ＳＰＭ上发生吸附，尤以ＴＢＴ更为显著．吸附速率可用Ｋｕｏ和Ｌａｋｅ的经验公式描述；吸附过程受ＳＰＭ的浓度及ＴＯＣ含量、ｐＨ值、温度、腐殖酸浓度和盐度影响．实际河口水样中的ＳＰＭ对ＴＢＴ和ＤＢＴ的吸附百分率也较高，因此ＳＰＭ是ＴＢＴ和ＤＢＴ归趋的重要场所，去除ＳＰＭ可使水体得到一定净化．     

DNA polymorphism and globin chain analysis in the prenatal diagnosis of β-thalassaemia major in Taiwan

Thirty-six pregnancies in 25 families at risk of β-thalassaemia major received prenatal diagnosis. Chorionic villus sampling or amniocentesis was done in 35 pregnancies to obtain fetal cells for DNA linkage study, for which Southern blotting and DNA hybridization were used to detect seven restriction fragment length polymorphisms (RFLPs) within the β-globin gene cluster: ϵ-HincII, ^Gγ-HindIII, ^Aγ-HindIII, Φβ-HincII, 3′Φβ-HincII, β-AvaII, and 3′β BarnHI. β-Thalassaemia major was diagnosed in seven and excluded in 22 pregnancies. In the remaining six cases, β-thalassaemia major could not be excluded. In these six pregnancies and another one with late booking, ultrasound-guided cordocentesis was performed at the 22nd to 27th week of gestation. Globin chain composition was determined with urea-acetic acid-Triton X-100-12 per cent polyacrylamide gel electrophoresis. β-Thalassaemia major was diagnosed in two fetuses and excluded in the other five. Eleven fetuses (in which β-thalassaemia major was excluded) have been delivered and are healthy at more than 5 months old DNA linkage analysis coupled with globin chain electrophoresis provides an effective way for prenatal diagnosis of β-thalassaemia major, although these methods are being replaced by more direct detection techniques using oligonucleotide probes.     

Detection of fetal HLA-DQα sequences in maternal blood: A gender-independent technique of fetal cell identification

The objective of this study was to detect fetal HLA-DQα gene sequences in maternal blood. HLA-DQα genotypes of 70 pregnant women and their partners were determined for type A1. We specifically sought couples where the father, but not the mother, had genotype A1. In 12 women, maternal blood samples were flow-sorted. Candidate fetal cells were isolated and amplified by using PCR primers specific for a paternal HLA-DQα A1 allele. Fetal HLA-DQα A1 genotype was predicted from sorted cells; amniocytes or cheek swabs were used for confirmation. Six of twelve sorted samples had amplification products indicating the presence of the HLA-DQα A1 allele; 6/12 did not. Prediction of the fetal genotype was 100 per cent correct, as determined by subsequent amplification of amniocytes or cheek swabs. We conclude that paternally inherited uniquely fetal HLA-DQα gene sequences can be identified in maternal blood. This system permits the identification of fetal cells independent of fetal gender, and has the potential for non-invasive prenatal diagnosis of paternally inherited conditions.
