The data showed that the level of serum CMSC and ICPIC was markedly decreased in acute phase and returned to normal in the 7th week after onset of disease.Correlation analysis revealed that there were positive correlation between the level of serum CMSC and ICPIC and the serum concentration of CH50, C3, C4, but no linear correlation between the level of serum CMSC and ICPIC and the amount of CIC. These results suggest that the declined serum CMSC and ICPIC in AGN may be associ ated with the pathogenesis of AGN.展开更多

Low concentrations of sodium salts of hexanoic, decanoic, palmitic and stearic acids were added to the prepared microemulsions to assess their ability to enhance microemulsion stability. Solubilization capacity of microemulsions was estimated and compared with their conductivities at the same water content. Solubilization capacity for YweenS0-containing microemulsions was found to be lower than that of Brij containing microemulsions. Different effects of the ionic surfactants at the maximum solubilization capacity were observed in both O/W and W/O microemulsions. Microemulsion conductivity results showed that different ionic surfactants exerted minor and comparable effects regardless to the implemented nonionic surfactant. Analysis of solubilization conductivity revealed that the presence of ionic surfactant can improve microemulsion solubilization capacity and provided that optimum physicochemical properties for both surfactants are fulfilled. These properties have direct impact at the goodness of the interracial film.展开更多
