Änderungen in den Lymphozytensubpopulationen, in der Expression von HLA-DR Antigen und Interleukin-2 Rezeptor bei Patienten mit Lupusnephritis

Abstract

In this study peripheral blood mononuclear cells were tested for T lymphocyte subpopulations, interleukin-2 receptor (IL-2R) and HLA-DR antigen by monoclonal antibodies in 14 LN patients. In comparison with normal controls, 14 LN patients showed a decrease of T4 lymphocyte (0.01 < P < 0.05) and increase of T8 cells (P < 0.01) with reduction of T4/T8 ratio (P < 0.01). The expression of HLA-DR cells increased (P < 0.01), the expression of IL-2R activated by PHA significantly decreased (P < 0.01), while nonactivated IL-2R expression significantly increased (P < 0.01). T4/T8 ratio was significantly correlated with activated IL-2R expression (P < 0.01, r = 0.6599). The results indicated that there was a immunological defect in LN patients. The pathogenesis of LN might be heterogeneous.

Disposal of 3.5-dinitro-benzoicacid Wastewater by Semi-Coke/Ozone Combined Technology

“…Water pollution is one of the major environmental problems our country is facing, the wastewater with nitro compounds does great harm to human, animal and plant, so treating the wastewater with nitro compounds is becoming increasingly important [1]. About removing the organic matter from wastewater using catalytic ozonation, a lot of research about catalyst are limited to the metal oxide and activated carbon, but the metal oxide dissolves out easily, the activated carbon is expensive and losts activity easily during the reaction [2,3,4,5,6].…”

The effects of pH, initial concentration, ozone flow, temperature and semi-coke dosage on 3.5-dinitro-benzoic acid wastewater in the process of carbocoal catalytic ozonation are investigated. The results show that: the removal rate of COD increases with the rise of ozone flow and reaction time in a certain range; temperature has little effect on the removal rate of COD; the removal rate of COD achieve the maximum value when the pH is about 12; the COD removal rate of carbocoal catalytic ozonation is obviously better than single ozonation.

Evaluation of Airport Pavement Service Performance Based on Fuzzy Matter Element and Combination Weights Method

“…Occident countries started the systemic research of airport pavement performance evaluation from 1970s, the U.S. army corps of engineers at Wright-Patterson Air Force Base established the first airport pavement evaluation group in 1972, USACERL proposed the Pavement Condition Index(PCI) and a complete set of investigation, analysis and evaluation methods in 1981, and then developed the first airport pavement administration system in the world, DYNATEST adopted PCI research date, FWD testing date and Friction Coefficient to synthetically evaluate the pavement condition. In our country, the development of pavement evaluation research was laggard, Tongji University with Shanghai aerodrome as the base to develop the theoretic research of pavement evaluation [1,2], after 2002, Shanghai Pudong international airport and Tongji university cooperated and developed a suit of airport pavement administration systems aimed at Shanghai international airports [3]. But in China, there still had not formed a suit of airport pavement performance evaluation systems with strong applicability [4].…”
