Surface chemical characterization of deactivated low-level mercury catalysts for acetylene hydrochlorination

Mercury-containing catalysts are widely used for acetylene hydrochlorination in China. Surface chemical characteristics of the fresh low-level mercury catalysts and spent low-level mercury catalysts were compared using multiple characterization methods. Pore blockage and active site coverage caused by chlorine-containing organics are responsible for catalyst deactivation. The reactions of chloroethylene and acetylene with chlorine free radical can generate chlorine-containing organic species. SiO_2 and functional groups on activated carbon contribute to the generation of carbon deposition. No significant reduction in the total content of mercury was observed after catalyst deactivation, while there was mercury loss locally. The irreversible loss of HgCl_2 caused by volatilization, reduction and poisoning of elements S and P also can lead to catalyst deactivation. Si, Al, Ca and Fe oxides are scattered on the activated carbon. Active components are still uniformly absorbed on activated carbon after catalyst deactivation.

ICOS-Ig combined with CsA induces long term survival of cardiac allografts in mouse

Objective： To study the synergistic effect of ICOS-Ig combined with cyclosporine （CsA） on mouse heart transplantation and explore its therapeutic potential. Methods： ICOS-Ig fusion protein was generated by fusing the extraeellular portion of human ICOS and Fc portion of human IgG. To investigate the effect of ICOS-Ig on T-cell proliferation in vitro, ICOS-Ig or IgG was added to the primary MLR cultures （BALB/c spleen T cells as responder cells and irradiated C57BL/6 spleen cells as stimulator cells）. The cells responsiveness rates were detected by 3H-TdR methods. Then the T cells of each group in primary MLR were cultured as responder cells for secondary MLR, and irradiated C57BL/6 （donor） or C3H （third party） spleen cells as stimulator cells. To study the effect of ICOS-Ig on T-cell proliferation in vivo, CFSE-labeled C57BL/6 spleen cells were transferred to irradiated BALB/c mice. Mice were then treated with IgG, ICOS-Ig or CsA. Seventy two hours after transfer, the spleen cells of the mice were harvested for the detection of CD4^＋CFSE^＋ and CD8^＋CFSE^＋ by FACS. C57BL/6 mouse underwent transplantation of the hearts of BALB/c mouse and were then randomly divided into five equal groups： no treatment group, control lgG treated group （250 gg i.p. d2, 4, 6）, ICOS-Ig treated group （250 μg i.p. d2, 4, 6）, CsA treated group （10 mg/kg i.p. d0-6）, ICOS-Ig combined with CsA group. The cardiac allograft survival was monitored by daily palpation. Results： In primary MLR, ICOS-Ig inhibited T-cell proliferation, （inhibition ratio 58i8.2% in 50 μg/ml）. In secondary MLR, ICOS-Ig specifically inhibited donor spleen cells, which suggested ICOS-Ig could induce donor-specific hyporesponsiveness. In the CFSE dye assay, CD4^＋CFSE^＋ and CD8^＋CFSE^＋ in ICOS-Ig and CsA group was stronger than those in control group, which showed ICOS-Ig and CsA could inhibit the proliferation of allo-reactive T cells in vivo. In mouse heart transplantation model, survival was significantly prolonged in animals treated with ICOS-Ig or CsA as compared with controls. Moreover, ICOS-Ig combined with CsA group had even longer engraftment （〉100 d） than ICOS-Ig or CsA used alone. In histological examination, it was found that there were congestions and edemas in no treatment and IgG treated recipients, together with a lot of inflammatory cells infiltrated. Allogeneic hearts from ICOS-Ig and/or CsA immunized recipients revealed milder histological changes. It was revealed in mechanical analysis that splenic T cells from recipients also exhibited depressed mixed leukocyte reactions （MLR） and cytotoxic lymphocyte reactions （CTL）. Conclusion： These data suggest that ICOS-Ig combined with CsA induces a long-term survival of mouse cardiac allografts, whereas monotherapy is less effective in this regard. Thus, ICOS-Ig combined with CsA treatment may be a novel regimen to combat allograft rejection.

Expired drugs as vapor-phase corrosion inhibitors of copper in simulated marine atmospheric environment

Urea,paracetamol and glutamine(based on the expired drugs)were selected as vapor-phase corrosion inhibitors(VCIs)to study their corrosion protection effect on red copper in simulated marine atmospheric environment by using weight loss,electrochemical measurement techniques(specially designed electrochemical testing device for simulating marine atmospheric environments)and surface morphology characterization analysis(SEM/EDS,XRD,RAMAN,XPS).Weight loss results show that the three corrosion inhibitors have good corrosion inhibition effect on red copper,and the corrosion inhibition efficiency in the order of glutamine(83.62%)>urea(68.46%)>paracetamol(61.47%).Surface morphology characterization analysis provides evidence of adsorption of corrosion inhibitors molecules on the red copper surface,thus forming a protective film that blocked the red copper surface from the aggressive chloride ion attack.

STUDIES ON CULTIVAR-INDUCED CHANGES IN INSECTICIDE SUSCEPTIBILITY AND ITS RELATED ENZYME ACTIVITIES OF THE WHITE BACKED PLANTHOPPER, SOGATELLA FURCIFERA (HORVTH) (HOMOPTERA:DELPHACIDAE)

The susceptibility of Sogatella furcifera female adults on N22 to malathion increased as feeding time prolonged, while the day change of susceptibility to isoprocarb showed a inverse tendency. The activities of esterase and carboxylesterase were induced significantly after on N22 for one day, and then declined. The non susceptible level of adults to insecticides and enzyme activities seemed to be heightened after feeding on ASD7, a variety resistant to Nilaparvata lugens. The total phenol content in rice leaf sheath was the highest in N22, and could be regarded as one of the factors, which caused chages in susceptibility of S. furcifera to insecticide after feeding different rice varieties. It was recommended that suitable insecticides and planthopper resistant varieties should be coordinately used in practice so that they contribute more effects respectively.
