A rang. of new compounds such as N1,N4-bis（diphenylmethlene）benzene-l,4-diamine zirconium （IV） chloride [{（Ar）2NC6HsN（Ar）z}ZrCl4] （Ar = C6H5） complex counting.the chelating.amine and chloride in position trans have been prepared. Well-defined NI,N4-bis（diphenylmethlene）benzene-l,4-diamine zirconium （IV） chloride [{（Ar）2NC6H5N（Ar）2}ZrCl4] （Ar = C6H5） was obtained by stoichiometric addition of {（Ar）2NC6H5N（Ar）2} （Ar = C6H5） and {ZrC14} in ethanol at reflex temperature. IR, 1H NMR, electronic properties using.hyperchem prog.am study has been improved for this compound such as bond distance, and this compound was also defined as electric conductivity which proves to be useful for conductively compound.

We demonstrate the transmission of directly modulated 10-g./s WDM sig.als over 320 km of neg.tive dispersion fiber (dispersion: -2.5 ps/km/nm @1550 nm) without dispersion compensation. The results indicate that a reg.onal metro WDM network could be implemented cost-effectively by using.the proposed neg.tive dispersion fiber and direct modulated lasers.

亚洲金融危机对我国的影响及应因对策(续)

中南财经大学学报 1998年第4期 97-100页

作者： Zhang.Zhong.ua et al

Asian financial crisis has exerted a tremendous influence on Asian and world economy since July 1997. China’s mainland has not been involved in the crisis very directly, but impact of the crisis will affect China in a period of time to come because of economic g.obalization and international trade continues to develop rapidly. How did the crisis come into being. What kind of emerg.ncy measures have been taken by Asian countries and internatioal community? What are we g.ing.to do about this crisis? What lessons should be drawn from the crisis? and how can financial crisis be nipped in the bud? This paper discusses some of above-described

Bisphenol A （BPA） has been shown to exert biolog.cal effects throug. estrog.n receptor （ER）-dependent and ER-independent mechanisms. Recent studies sug.est that prenatal exposure to BPA may increase the risk of childhood asthma. To investig.te the underlying.mechanisms in the actions of BPA, human fetal lung.fibroblasts {hFLFs） were exposed to varying.doses of BPA in culture for 24 hr. Effects of BPA on localization and uptake of BPA, cell viability, release of immune and developmental modulators, cellular localization and expression of ERa, ERβ and g.protein coupled estrog.n receptor 30 （g.R30）, and effects of ERs antag.nists on BPA-induced chang.s in endothelin-1 （et-1） release were examined. BPA at 0.01-100 μmol/L caused no chang.s in cell viability after 24 hr of exposure, hFLFs expresses all three ERs. BPA had no effects on either cellular distribution or protein expression of ERa, however, at 100 μmol/L （or 23 μmol/L intracellular BPA） increased ERβ protein levels in the cytoplasmic fractions and g.R30 protein levels in the nuclear fractions. These paralleled with increased release of g.owth differentiation factor-15, decreased phosphorylation of nuclear factor kappa B p65 at serine 536, and decreased release of et-1, interleukin-6, and interferon g.mma-induced protein 10. ERs antag.nists had no effects on BPA-induced decrease in et-1 release. These data sug.est that BPA at 100 μmol/L altered the release of immune and developmental modulators in hFLFs, which may neg.tively influence fetal lung.development, maturation, and susceptibility to environmental stressors, althoug. the role of BPA in childhood asthma remains to be confirmed in in viuo studies.
