Abstract: A cerium oxide nanocomplex, a composition containing the cerium oxide nanocomplex as an active ingredient, and their uses for preventing or treating inflammatory liver disease are disclosed. The present disclosure applies a biocompatible polymer composed of an optimal combination to significantly improve the biomedical stability, biosynthesis and efficiency of the production process of nanoparticles while maintaining the nanoparticles' excellent inhibitory activity against inflammation. In particular, the present disclosure may be applied as an effective therapeutic composition that effectively controls excessive immune response and inflammatory response and tissue injury in acute liver failure which is a serious condition of rapid loss of liver function that results in multiple organ failure and death.

Abstract: A cerium oxide nanocomplex, a composition containing the cerium oxide nanocomplex as an active ingredient, and uses thereof for preventing or treating peritonitis are disclosed. The cerium oxide nanocomplex improves the biomedical stability, biocompatibility, and efficiency of the production process of nanoparticles while maintaining the excellent inhibitory activity against inflammation by applying a biocompatible polymer composed of an optimal combination. The cerium oxide nanocomplex may be used as an excellent therapeutic composition that may greatly improve patients' survival rate by effectively inhibiting inflammatory response and quickly blocking tissue damage at early stage of peritonitis when a radical inflammatory injury occurs because of the penetration of bacteria, foreign body and immune cells into a perforated organ in the abdominal cavity.
Abstract: A cerium oxide nanocomplex, a composition containing the cerium oxide nanocomplex as an active ingredient, and their uses for preventing or treating brain edema are disclosed. The composition can be used as an efficient nanoparticle therapeutic composition by applying a biocompatible polymer composed of an optimal combination to significantly improve the biomedical stability, biocompatibility, and efficiency of the production process of nanoparticles while maintaining the nanoparticles' excellent inhibitory activity against inflammation. In particular, the composition may be used as an effective therapeutic agent that may help patients with severe cerebral infarction recover their neurological function and greatly improve their survival rate by inhibiting secondary inflammatory response and minimizing tissue injury caused by brain edema.
