大庆红岗生态工业园区创建的现有条件

生态工业园是根据循环经济理念和工业生态学原理而设计建立的一种新型工业组织形态,在园区内通过废物交换、循环利用、清洁生产等手段,实现资源利用的最大化和废物排放的最小化.文章通过对大庆市石油、石油化工产业链现状分析及产品代谢和废物代谢分析,说明大庆红岗具有创建生态工业园区的区位和资源优势,园区所在区域内现已经初步形成了石油开采、石油化工、轻烃加工和化工建材产业(品)代谢连及废油、废水回注等废物代谢链的生态工业雏形,为创建大庆红岗生态工业(石化)示范园区奠定了一定的基础.

Flow sorting of fetal erythroblasts using intracytoplasmic anti-fetal haemoglobin: Preliminary observations on maternal samples

Monoclonal antibody to fetal haemoglobin (a₂γy₂) has been proposed as a fetal-specific reagent. We developed an intracellular staining protocol that combines fluorescein isothiocyanate or phycoerythrin conjugated anti-γ with the DNA binding dye Hoechst 33342 to identify and flow sort fetal erythroblasts from maternal blood. Our preliminary observations on anti-γ-positive cells sorted from four different pregnant women are described here, using fluorescence in situ hybridization (FISH) with chromosome-specific probes to identify fetal cells. Our data demonstrate that far fewer candidate fetal cells are sorted with this protocol than by current cell surface staining methods that employ the monoclonal antibody CD71. This results in increased fetal cell sorting purities. With this protocol, standard FISH techniques require modification due to the rigorous fixation with 4 per cent paraformaldehyde. Our initial data indicate the promise of this approach.     

废水中有机物对铁盐除磷的影响

通过批次实验探究了不同有机物对铁盐化学除磷的影响.结果显示，有机物对铁盐化学除磷的不利影响由强到弱依次为柠檬酸、黄腐酸、聚山梨酯-80、牛血清蛋白、葡萄糖、淀粉，柠檬酸的影响程度为其他五种有机物的5~20倍.较之含羟基有机物，含羧基有机物对铁盐除磷的不利影响更大.研究表明：铁盐化学除磷的实质是通过形成铁羟基氧化物（HFO）来除磷.含羧基有机物，如柠檬酸，可与磷酸根竞争HFO，有机物"抢占"HFO表面结合位点导致磷酸盐与HFO结合减少，从而使铁盐除磷效果下降.在所试柠檬酸浓度范围内，铁盐除磷率最高下降了90.70%.

The safety of fetoscopy: (I). Effect of umbilical vessel puncture on the fetal heart rate and cord histology

The fetal heart rate (FHR) was continuously monitored during 42 umbilical vessel punctures performed at the placental insertion of the cord in 24 diagnostic fetoscopies in which pure fetal blood was obtained. In only one patient did a deceleration first appear during puncture and aspiration of fetal blood. In two patients decelerations preceded fetoscopy and in two others they began during the fetoscopy but before puncture of an umbilical vessel. In 19 patients, the FHR did not change at all during the procedure. Fetal haemorrhage after sampling was either absent or minimal. Six pregnancies were terminated because a positive diagnosis had been made and 18 healthy babies were born. Umbilical cords were examined after 7 terminations of pregnancy and after 6 deliveries. In the former group the puncture could just be seen with the naked eye and the needle track was demonstrated histologically in 6. No traces of the puncture or other abnormalities were found in the cords after delivery. Fetal blood sampling from umbilical cord vessels, particularly at the placental insertion of the cord, is the technique of choice since pure fetal blood can be obtained without increasing the risk of fetoscopy.
