Biosynthesis of cerium oxide nanoparticles and their effect on lipopolysaccharide (LPS) induced sepsis mortality and associated hepatic dysfunction in male Sprague Dawley rats.

Biosynthesis of cerium oxide nanoparticles and their effect on lipopolysaccharide (LPS) induced sepsis mortality and associated hepatic dysfunction in male Sprague Dawley rats. Mater Sci Eng C Mater Biol Appl. 2018 Feb 01;83:148-153 Authors: Chen G, Xu Y Abstract The fetal/life challenging Sepsis is an urgent medical disaster which have developed "blood poisoning". The sepsis is one of the disorders of organs which cause death in patients. The investigational models that mimicchemical change of sepsis in human bodywereessential. We have synthesized CeO2 NPs using eco-friendly method using plant extract. The characterization of synthesized CeO2 NPs was studied using UV-Vis, FTIR, XRD, SEM, EDX and TEM analysis. The results were confirmed that the synthesized CeO2 was in nano size with spherical shape. The synthesized CeO2 nanoparticles were evaluated against lipopolysaccharide (LPS) male Sprague Dawley rats. We have intravenously administrated CeO2NPs (0.5mg/kg) to Sprague Dawleyratswhich are septic and checked the death rate, respiratory rate, blood pressure, body temperature. The rats could restore all parameters with decrease in hepatic damage, serum cytokines/chemokines, and swelling indicators. The Kupffer cells and macrophage cells treated with CeO2NPs and showed lowest TNF-a, IL-1b, IL-6, and HMGB1release. Due to the ROS, iNOS, COX-2, and nuclear factor-kappa light chain, the triggered B cells (NF-kB) transcriptional action was...
