Chlorine atoms were ？rstly introduced into lignin through its etheri？cation with epichlorohydrin. Then, hydrophilic amine groups were grafted to the modi？ed lignin structure through amination with ethylenediamine to obtain AEL. Subsequent acidi？cation of AEL led to the ionized aminated lignin （IAEL）. The results of our analyses showed that the nitrogen content of AEL was 6.9%. Foaming and emulsifying experiments indicated that AEL had better foamability and emulsifying properties than IAEL. Surface tension tests showed that AEL and IAEL had similar critical micelle concentration （CMC）. However, IAEL had lower surface tension （36.33 mN/m） than AEL （42.89 mN/m） at CMC. These results demonstrate the promising applicability of AEL as an emulsi？er and that of IAEL as feedstock in the production of detergent and dispersant.展开更多

Methods： Made detailed data about allergic reactions to oxaliplatin from 10 patients in our department, and made analysis and discussions about it while referring to related reference. Results： All the 10 patients had no history of allergies, 4 cases of allergies occurred during the course of multi-cycle chemotherapy, and 6 cases occurred on the first time of drug administration, whose allergic symptoms were present in the process of using oxaliplatin, with the infusion time from 10 to 25 rain. When relevant treatments such as drug withdrawal, hormone, intravenous calcium gluconate and magnesium sulfate were done to the patients, related symptoms could be soon relieved. Conclusion： Mechanisms of oxaliplatin allergic are still unclear. Applying calcium and magnesium may reduce the risk of neurotoxicity and reduce the degree of allergic reactions before administration of oxaliplatin.展开更多

This extraordinary profile was possible thanks to the use of phosphorus dendrimers for which various techniques of deposition on a given support were investigated and described and analyzed in this report.展开更多
