A new method of indirect determination of ascorbic acid(Vc) with ammonium sulfate and isopropyl alcohol by extraction-flotation of copper is studied in this paper. It shows that a small amount of Cu(Ⅱ) can be reduced to Cu( Ⅰ ) by Vc, then Cu(Ⅰ) reacted with the SCN-, which precipitated on the interface of isopropyl alcohol and H2O. A good linear relationship is observed between the flotation yield(E) of Cu( Ⅱ) and the amount of Vc. The detection limit for Vc is 1.76μg/mL. The method is simple, rapid (5 min), but suffers from little interference of common anions and cations. It has been successfully applied for the determination of Vc in fruits.

Male Sprague-Dawley rats administered xylene intrapetitoneally on alternate days at a dose of 125 or 250mg/kg for 30 days exhibited no marked changes in locomotor activity, learning and memory capacity. However in rats given xylene on alternate day at a dose of 500 mg/kg for 30 days, a significant decrease in locomotor activity, deficits in leaming ability and memory loss were detected. These xylene-induced behavioral ehanges were assoryiated with a decrease in fyendorphin and leuenkaphlin concentrations in the pons-medulla. On the contrary, xylene at a dose of 500mg/kg increased the β-endorphin level in caudate and c-fos expression in hippocampus. These data suggest that the xylene-induced behavioral alterations might be associated with the expression of Fos protein in the hippocampus.

查明油页岩的形成背景和高品质油页岩形成机制是开展油页岩原位改造的基础工作.利用有机碳、主微量元素、稀土元素、生物标志物等地球化学方法,对茂名盆地油柑窝组油页岩的沉积环境进行恢复并探讨了有机质聚集机制.结果表明,茂名盆地油柑窝组全段油页岩均富有机质,底部为薄层碳质页岩、砂岩和褐煤层段.Mo含量、Ba/Al、Ba_(bio)和生物标志物特征表明油柑窝组具有很高的初级生产力,油柑窝组存在间断性的“藻类勃发”现象;V/(V+Ni)、Ce_(anom)、Th/U、草莓体黄铁矿颗粒大小和Pr/nC_(17)-Ph/nC_(18)交汇图表明了沉积水体处于缺氧还原环境;Sr/Cu、Rb/Sr和气候指数C指示油柑窝组为温暖湿润的古气候条件;Sr/Ba、Ba/Ga、Ca/(Fe+Ca)、Al_(2)O_(3)/MgO以及伽马蜡烷等特征反映了古湖泊水体为淡水;Zr/Al、Rb/K和MnO含量指示为半深湖-深湖沉积环境.通过各指标与TOC含量之间的相关性分析,认为温暖湿润气候和淡水环境为藻类的繁盛提供了良好的环境,具备很高的初级生产力,直接影响了油页岩的品质和发育特征,具有丰富有机质来源的表层生产力是油页岩形成的首要条件,缺氧还原的半深湖-深湖环境有利于沉积有机质堆积和保存,是有机质聚集的促进因素.综合各因素,提出了茂名盆地油柑窝组优质油页岩有机质的聚集模式.
